Indonesia’s Orangutans and the Peatland Carbon Bomb
Indonesia is experiencing a dangerous convergence of climate stress, extreme drought, human land-use change, and wildfire across Sumatra and Borneo. As of September 2026, satellite observations indicate that more than 200,000 hectares have burned, releasing enormous quantities of greenhouse gases while blanketing large portions of Southeast Asia in toxic smoke and haze.
For Indonesia’s orangutans, this is more than a wildfire crisis. It is an accelerating ecosystem crisis in which climate change, drought, deforestation, and peatland destruction reinforce one another.
The Climate Change Feedback Loop
Climate change does not have to ignite a wildfire to make a fire catastrophe more likely. Instead, warming can intensify the environmental conditions that allow fires to spread, burn longer, and become increasingly difficult to control.
Indonesia’s recurring dry seasons are strongly influenced by natural climate variability, particularly El Niño. But a warmer climate can load the system with additional heat and alter the background conditions under which these natural cycles operate. During an exceptionally strong El Niño, prolonged drought and extreme heat can turn already vulnerable landscapes into tinderboxes.
That becomes particularly dangerous in Indonesia’s peatlands.
The Peatland Carbon Bomb
Indonesia contains vast tropical peatlands—wetlands formed from layers of partially decomposed organic material accumulated over thousands of years. When these ecosystems remain saturated, the waterlogged peat is relatively resistant to burning.
But decades of drainage and conversion for agriculture, palm-oil production, pulpwood plantations, roads, and other development have transformed many peatlands into something fundamentally different: enormous stores of carbon sitting above the water table.
Once dried, peat can ignite and continue smoldering underground. A surface fire may disappear while combustion continues below ground, allowing fires to persist for weeks or months and re-emerge far from the original ignition point.
Peat fires are also major sources of fine particulate pollution, creating severe health impacts across Indonesia and neighboring countries. Unlike an ordinary forest fire, a peat fire can continue consuming carbon-rich soil beneath the surface, releasing greenhouse gases long after the visible flames have disappeared.
From Forest Fire to Climate Feedback
The significance extends far beyond the individual fire.
When forests and peatlands burn, carbon that had been stored in vegetation and soil for centuries or millennia is rapidly transferred into the atmosphere. The resulting greenhouse-gas emissions contribute to additional warming, while the loss of forest reduces the ecosystem’s capacity to store carbon in the future.
This creates another reinforcing loop:
Forest and peatland destruction → carbon release → atmospheric warming → greater drought and heat stress → increased fire vulnerability
The system can therefore begin amplifying itself.
The Orangutan Connection
Orangutans are among the most visible casualties of this feedback system. Their remaining habitat is concentrated primarily in the forests and peatlands of Borneo and Sumatra. When these landscapes are cleared, drained, fragmented, or burned, orangutans lose not simply individual trees but entire interconnected ecosystems on which their survival depends.
Fire can kill animals directly, separate populations, destroy food sources, and further fragment already shrinking habitat. Smoke and prolonged drought add additional stress.
The orangutan therefore provides a remarkably tangible way to understand climate energy.
The heat accumulating in the Earth system does not remain an abstract number on a graph. It manifests through drought, altered rainfall, drying wetlands, wildfire, habitat destruction, ecosystem collapse, and ultimately the loss of living organisms.
A Global Feedback
The danger does not end at Indonesia’s borders.
Between September 1 and September 7, 2026, reported wildfire emissions were estimated to have increased dramatically, with approximately 19.7 million tons of carbon dioxide released during that period. If confirmed, such emissions demonstrate how rapidly a regional ecological disturbance can become part of the global climate system.
Indonesia’s peatlands are effectively biological carbon reservoirs. When they remain wet and intact, they help keep carbon out of the atmosphere. When they are drained and burned, they can become carbon sources instead.
That is the paradox of the peatland carbon bomb:
The ecosystem that once stored carbon becomes an engine for releasing it.
Climate Energy Is Coming Back Around
This is what makes Indonesia’s wildfire crisis so important in understanding climate change.
Climate energy moves through the Earth system. The atmosphere warms. Oceans redistribute enormous quantities of heat. Atmospheric circulation changes. Drought and precipitation patterns shift. Vegetation becomes stressed. Wetlands dry. Fire releases stored carbon. Carbon dioxide and other greenhouse gases increase atmospheric energy retention.
The process is not a simple straight line from warming to fire.
It is a feedback system.
Warming → drought → fire → carbon release → more warming → greater vulnerability
And in Indonesia, that feedback is colliding with one of the planet’s most biologically important ecosystems.
The orangutan is not separate from the climate system.
Neither is the peat beneath its feet.
The fire is where the climate feedback becomes visible.
🏔️ SIMPLIFIED INTRODUCTION: MOUNTAIN GLACIERS AT THE EDGE
Mountain glaciers are disappearing faster.
But the bigger danger may be what happens to the mountains when the ice disappears.
Record global heat and the powerful 2023–2024 El Niño helped drive extraordinary glacier mass loss worldwide. Now, with another potentially powerful El Niño developing against an already overheated climate, the consequences extend far beyond shrinking glaciers.
Extreme heat melts glacier ice.
Permafrost thaws.
Mountain slopes weaken.
Rain replaces snow.
Atmospheric rivers deliver enormous amounts of water.
Landslides block rivers.
Temporary lakes form.
And those lakes can suddenly burst downstream.
The danger is no longer simply ICE LOSS.
It is SYSTEM INSTABILITY.
This is what happens when multiple climate-sensitive systems begin moving together—and feedbacks start turning one disturbance into another.
Tipping Point Season: Mountain Glaciers at the Edge
The mountain isn’t just losing ice.
The mountain is changing.
The Full Report
The combination of the powerful 2023–2024 El Niño and record-breaking global heat severely accelerated the loss of mountain glaciers worldwide, producing some of the largest glacier mass-balance deficits ever recorded. What makes this period particularly important is not simply the amount of ice being lost, but the way extreme heat, altered precipitation, permafrost thaw, and increasingly volatile hydrology are beginning to interact across high-mountain environments.
2023–2024: A Global Glacier Mass-Loss Shock
Data compiled by the World Glacier Monitoring Service (WGMS) and the United Nations illustrate the extraordinary scale of recent glacier deterioration. The compounding effects of human-induced climate change and the 2023–2024 El Niño contributed to exceptionally severe melting conditions.
Record-breaking global mass loss
During the 2023 hydrological year, glaciers experienced a record-breaking global mass loss equivalent to approximately 1.1 meters of ice thickness. The total loss was roughly 600 gigatons of water, making 2023 the largest annual glacier mass loss recorded since systematic measurements began in 1976.
The deterioration continued in 2024. The 2024 hydrological year ranked as the fourth-worst year on record, with glaciers losing another approximately 450 billion tonnes of ice. It also marked the third consecutive year in which all 19 glacier regions monitored globally experienced a net mass loss.
The significance of these numbers extends beyond the glaciers themselves. Mountain glaciers function as frozen reservoirs, storing water that is gradually released into downstream river systems. Their rapid depletion therefore represents both a cryospheric transformation and a growing threat to water security, ecosystems, agriculture, hydropower, and communities downstream.
Tropical Glaciers: Exceptionally Vulnerable
Tropical glaciers, particularly those in the Andes and Indonesia, are exceptionally sensitive to changes in precipitation and temperature. The 2023–2024 El Niño amplified those vulnerabilities.
In the Peruvian Andes, research on the Quelccaya Ice Cap has shown how El Niño can suppress wet-season snowfall, replacing it with warmer and drier conditions. Fresh snow normally provides a highly reflective surface that returns much of the incoming solar energy back to space. When snowfall fails and bare glacier ice is exposed, the darker surface absorbs substantially more solar energy.
This creates a powerful feedback: less snowfall means less reflective snow cover; less reflective snow means greater absorption of solar energy; greater energy absorption accelerates melting and exposes still more bare ice.
Indonesia’s Puncak Jaya glaciers face an even more precarious future. These rare tropical glaciers were already critically endangered, and drought and temperature anomalies associated with El Niño accelerated the timeline toward potential disappearance.
European Alps and North American Ranges
El Niño does not directly control the climate of every mountain region. Its effects are superimposed on a much larger background trend of human-driven global warming.
In the European Alps, persistent and intense summer heatwaves produced severe glacier degradation. Melting occurred even at elevations above approximately 3,100 meters—heights that historically provided substantially greater protection from summer heat.
The North Cascades of the United States experienced a similar pattern. In areas such as North Cascades National Park, monitored glaciers continued to lose mass through both 2023 and 2024, consistent with a broader regional trend in which glacier melt rates have increased dramatically over recent decades.
The important signal is therefore not simply that glaciers are retreating. It is that the elevation, duration, and intensity of melting are changing. Ice that once remained protected through the summer is increasingly being exposed to temperatures capable of transforming both the surface and the internal structure of mountain glaciers.
The 2023–2024 Glacier Signal
Metric / Region
Impact from 2023–2024 Heat and El Niño
Global Mass Loss
2023 was the worst year on record, with approximately 600 Gt of ice lost. 2024 ranked fourth-worst. All 19 monitored glacier regions experienced net loss.
Tropical Glaciers
Reduced seasonal snowfall combined with extreme heat exposed darker bare ice, accelerating thinning and shortening extinction timelines.
Mid-Latitude Glaciers
Extreme high-elevation temperatures pushed the melt zone upward, exposing previously protected ice to rapid melting, fracturing, and structural deterioration.
Sea-Level Contribution
Glacier mass loss adds freshwater directly to the oceans, compounding sea-level rise driven by thermal expansion and other sources.
But the story does not end with glacier retreat.
The more consequential question is what happens when a warming atmosphere begins to destabilize the mountains surrounding and supporting those glaciers.
2026–2027: From Glacier Loss to Mountain Instability
The emerging 2026–2027 El Niño is occurring against an already unprecedented background of global warming. If the event develops with the exceptional strength currently being discussed, its influence will not be confined to ocean temperatures or atmospheric circulation.
High-mountain environments are particularly vulnerable because they sit at the intersection of several climate-sensitive systems: glaciers, snowpack, permafrost, steep rock faces, atmospheric circulation, and rapidly responding river networks.
The result can be a chain reaction in which one disturbance increases the probability or severity of another.
1. The Nepal–Tibet Glacial Collapse
The catastrophic disaster reported along the Nepal–Tibet border on August 26, 2026, provides a stark example of how extreme heat can intersect with high-altitude geological instability.
A massive section of glacier collapsed at approximately 5,200 meters, triggering an enormous avalanche of ice, rock, and mud that moved into the Trishuli and Bhotekoshi River valleys. The resulting destruction affected communities and critical infrastructure, including hydropower facilities and border transportation routes.
The thermal environment preceding the collapse is particularly significant. Meteorological analysis reportedly found prolonged and exceptional warmth at the elevation of the glacier, with temperatures averaging approximately 5°C (41°F) over a six-day period. Such temperatures are extraordinary at 5,200 meters and illustrate how extreme atmospheric warmth can penetrate environments historically protected by elevation.
The lesson is larger than a single glacier failure.
When temperatures rise far enough, high altitude is no longer the same form of protection it once was.
2. Feedback Mechanism: Permafrost Thaw and Slope Failure
Glacier retreat is only one component of high-mountain destabilization. Permafrost provides another critical structural control.
Permafrost consists of permanently frozen soil, rock, and ice. In steep mountain terrain, frozen water can act as a form of geological glue, binding fractured rock and stabilizing slopes.
Extreme warming attacks that structural support.
As temperatures rise, permafrost can thaw progressively deeper into mountain slopes. Ice within fractures melts, reducing the cohesion between rock surfaces. Water can then penetrate deeper into the fractured rock, while repeated freeze-thaw cycles and changing hydraulic pressures further weaken the structure.
The result can be slope failure.
A destabilized glacier, hanging ice mass, or fractured rock face may collapse as a single event, but the material released does not necessarily remain an avalanche of ice. It can entrain enormous quantities of rock, soil, sediment, and meltwater.
What begins as a glacier or rock failure can therefore become a high-speed debris flow or mudslide carrying millions of tonnes of material downstream.
This is a critical transition: climate change is not simply removing ice from mountains; it can alter the mechanical stability of the mountains themselves.
El Niño reorganizes global atmospheric circulation and changes the distribution of heat and moisture across the planet. Warmer ocean surfaces provide greater evaporation potential, increasing the amount of water vapor available to the atmosphere.
That additional atmospheric moisture can feed powerful atmospheric rivers—long, narrow corridors transporting enormous quantities of water vapor.
When these systems encounter mountain ranges, the consequences can become extreme.
Instead of falling as snow, warm atmospheric rivers can produce rain at elevations that historically received substantial snowfall. This creates a particularly dangerous combination: rain-on-snow events occurring simultaneously with already accelerated glacier and snowpack melt.
4. The Hydro-Thermal Double Whammy
Rain falling on snow and ice does more than add water.
Rain transfers sensible and latent heat directly into the snowpack and glacier surface. At the same time, the enormous volume of rainfall can rapidly increase runoff.
The result is a hydro-thermal double whammy:
Heat accelerates melting while water accelerates runoff.
Mountain drainage systems can become overwhelmed as rainfall, snowmelt, and glacier melt converge. Steep terrain magnifies the response, sending water and sediment rapidly into narrow valleys.
If landslides or debris flows block those valleys, temporary lakes can form behind natural dams of rock, ice, and sediment. Such impounded water can subsequently breach the blockage, generating devastating downstream floods, including glacial lake outburst floods (GLOFs).
One climate disturbance can become a cascade of physical disturbances.
The Compounding Cycle of Mountain Hazards
Climate Driver
Direct Physical Change
Resulting Environmental Hazard
Record Ambient Heat
Extreme high-elevation temperatures accelerate surface melting and weaken glacier structures.
Rapid ice loss, glacier destabilization, and structural collapse.
Permafrost Thaw
Ice binding rock and soil begins to melt, weakening the mountain’s internal structure.
Whole-slope failures, massive rockfalls, and debris-laden mudslides.
El Niño–Driven Moisture
Warmer oceans increase evaporation and atmospheric moisture availability.
More powerful atmospheric rivers and extreme precipitation events.
Rain-on-Snow Events
Warm rainfall adds heat and water directly to mountain snow and ice.
Accelerated melt, rapid runoff, flooding, and landslides.
Cascading Hydrology
Landslide and debris-flow material blocks narrow river channels.
Temporary lakes and potentially catastrophic glacial lake outburst floods.
Tipping Point Season
The most important signal may therefore not be the disappearance of an individual glacier.
It may be the increasing synchronization of multiple mountain processes.
Glacier loss changes surface reflectivity and water storage. Permafrost thaw weakens mountain slopes. Extreme heat raises the elevation of the melt zone. Atmospheric rivers deliver greater quantities of warm precipitation. Rain-on-snow events accelerate runoff. Landslides alter river channels. Temporary lakes form behind unstable debris dams. Those lakes can subsequently fail.
Each process can amplify another.
This is what makes mountain glacier loss a potential tipping-point problem. The danger is not necessarily one dramatic threshold at which a glacier suddenly disappears. The danger is a system in which multiple thresholds are approached simultaneously, feedbacks proliferate, interactions strengthen, and individual disturbances begin producing consequences far beyond their original location.
The mountain system becomes increasingly nonlinear.
A glacier that once functioned primarily as a frozen reservoir can become a source of floodwater. Permafrost that once stabilized a mountain slope can become a liability when it thaws. Snow that once stored water safely through the winter can become a mechanism for rapid runoff when warm rain falls on it. A landslide that once would have been a localized geological event can block an entire river and create a secondary flood disaster.
The result is a shift from ice loss to system instability.
That may be the larger lesson of Tipping Point Season: climate change is not simply making glaciers smaller. It is changing the physical relationships among ice, rock, water, atmosphere, and gravity.
And when those relationships begin changing together, the mountain can stop behaving like the mountain we knew.
How Coupled Climate Feedbacks Are Accelerating Earth-System Change
By Daniel Brouse
Simplified Introduction to:
🌎 TIPPING POINT SEASON
Tipping points are not necessarily isolated events waiting to happen one at a time.
Several have already begun moving together.
Ice loss changes albedo. Arctic warming alters atmospheric circulation. Greenland melt adds freshwater to the North Atlantic. Permafrost thaws and releases greenhouse gases. Forests are stressed by heat, drought, and fire. Ocean and atmospheric systems respond.
The important question is no longer simply: When will a tipping point occur?
It is: What happens when multiple tipping elements begin interacting with one another?
Tipping points come together. Feedbacks proliferate. Interactions strengthen. And acceleration emerges.
The climate system begins to change faster and in more complex ways than its individual pieces can be understood in isolation.
That is the idea behind the paper:
Tipping Point Season: Comingling Tipping Points and Proliferating Feedbacks
How Coupled Climate Feedbacks Are Accelerating Earth-System Change
The greatest danger may not be one tipping point suddenly toppling.
It may be several moving together.
🌡️ 1.5°C is not a magical switch.
It is a tripwire into a climate system where more interconnected components are being pushed toward critical states.
Tipping Point Season has begun.
Comingling Tipping Points
The climate system has entered a new phase. The significance of the first sustained period in which global temperatures repeatedly exceeded 1.5°C above the pre-industrial baseline during 2023–2024 is not simply the number itself, but what is happening around that number. Across the planet, multiple components of the Earth system are simultaneously experiencing unprecedented or rapidly intensifying stress. Polar ice is disappearing, Arctic amplification is accelerating, permafrost is thawing, ocean heat content continues to rise, extreme marine heatwaves are becoming more consequential, and tropical forests are being stressed by increasing heat and drought. These are not isolated phenomena. They are interacting.
The central climate question is therefore changing. It is no longer sufficient to ask when an individual tipping point will be crossed. We must ask whether multiple tipping elements are already beginning to influence one another strongly enough to create a self-reinforcing cascade. The evidence increasingly indicates that they are. This is the comingling tipping points: a condition in which multiple vulnerable Earth-system components are changing simultaneously, altering the boundary conditions experienced by other components and strengthening feedbacks between them. The result is feedback proliferation. One change creates another, that change alters another part of the system, and the resulting response feeds back into the original disturbance. The climate system begins to behave less like a collection of separate components and more like a tightly coupled network. As coupling increases, the rate of change can increase with it.
1.5°C Is Not a Switch. It Is a Tripwire.
The 1.5°C threshold should not be imagined as a magical switch that suddenly activates every climate feedback. Climate feedbacks have always existed. What changes as warming increases is their strength, frequency, geographic extent, persistence, and interaction with other feedbacks. At approximately 1.5°C of global warming, numerous tipping elements become increasingly vulnerable, including Greenland ice-sheet instability, West Antarctic ice-sheet instability, Arctic sea-ice loss, permafrost thaw, boreal forest degradation, Amazon rainforest degradation, AMOC weakening, coral-reef collapse, and mountain-glacier loss.
These systems are connected through the atmosphere, oceans, cryosphere, biosphere, and hydrological cycle, and that connectivity matters. A warmer Arctic changes atmospheric temperature gradients; changing gradients alter circulation; circulation changes precipitation, drought, storm tracks, and heat transport; those changes affect forests, soils, glaciers, snowpack, and oceans. Ice loss changes albedo and freshwater delivery, while freshwater changes ocean density and circulation. Forest degradation changes carbon uptake and atmospheric moisture recycling, while permafrost thaw releases additional greenhouse gases. Each response changes the conditions under which the others operate. This is not theoretical coupling. It is the physical architecture of the climate system.
The El Niño Accelerator
ENSO provides another mechanism by which an already-warmed climate system can experience rapid additional warming. During El Niño, heat stored in the tropical Pacific is redistributed toward the atmosphere and higher latitudes, producing a temporary but potentially enormous pulse of global surface warming. A major 2026–2027 El Niño would therefore not be occurring in the climate system of the twentieth century; it would be occurring on top of a much warmer baseline.
That distinction is crucial because the same El Niño forcing applied to a cooler climate and a highly warmed climate does not necessarily produce the same system response. Background conditions have changed, and a strong El Niño can push global temperatures substantially above the 1.5°C level and potentially toward or beyond 1.6°C for extended periods. The danger is not that El Niño creates anthropogenic warming. Rather, an exceptionally warm baseline combined with a powerful natural climate oscillation can push already-stressed tipping elements closer to critical states simultaneously. A climate pulse can therefore become a trigger.
From Individual Tipping Points to Comingling Tipping Points
Consider the sequence already emerging across the polar climate system: polar amplification → weakened equator-to-pole temperature gradient → altered atmospheric circulation → accelerated Arctic and Greenland ice loss. That initial sequence immediately activates multiple feedbacks.
The ice–albedo feedback begins when ice loss exposes darker ocean and land surfaces. Those surfaces absorb more solar energy, producing additional regional warming and further ice loss: ice loss → darker ocean and land surfaces → greater solar absorption → additional warming → additional ice loss ↺. The Arctic consequently changes from a highly reflective surface toward a darker, increasingly heat-absorbing system.
At the same time, a melt–elevation feedback can develop as an ice sheet loses mass and elevation. Lower ice-sheet surfaces are exposed to warmer atmospheric conditions, increasing surface melting and producing further elevation loss: ice loss → lower ice-sheet elevation → exposure to warmer air → increased surface melting → additional elevation loss ↺. Arctic warming also alters the vertical temperature structure of the lower atmosphere, contributing to a lapse-rate feedback in which changes in the vertical temperature gradient can reduce atmospheric cooling efficiency near the surface and promote additional warming: Arctic warming → altered lapse rate → reduced atmospheric cooling efficiency near the surface → additional near-surface warming → additional ice and snow loss ↺.
These are not three independent feedbacks operating in isolation. They interact. The resulting cryospheric response can then connect to the ocean through accelerated Greenland melt and increased freshwater input into the North Atlantic. Freshwater can reduce salinity and density, contributing to AMOC weakening. Ocean circulation then connects back to the atmosphere through altered North Atlantic heat transport, pressure fields, and storm tracks. Atmospheric circulation can consequently reorganize, increasing jet-stream waviness and creating conditions favorable to persistent blocking.
The resulting sequence can extend into slower-moving Rossby waves, persistent blocking and omega blocks, prolonged heat domes, drought, stalled atmospheric rivers, and extreme precipitation. The consequence is hydroclimatic whiplash, in which the same atmospheric circulation regime can produce drought in one region and catastrophic flooding in another, sometimes in rapid succession. The components are no longer simply responding independently to global warming; they are modifying one another’s operating environment.
Feedback Proliferation
Once multiple tipping elements become coupled, the number of potential feedback pathways increases dramatically. A single change can propagate through several systems simultaneously. Consider the sequence: polar amplification → atmospheric circulation change → ice loss → albedo reduction → additional warming → Greenland melt → freshwater input → ocean circulation disruption → atmospheric circulation change → precipitation redistribution → drought and flood extremes → ecosystem stress → carbon-cycle disruption → additional greenhouse forcing → additional warming.
The system is now operating as a network of interacting positive feedbacks. This is why the phrase feedback proliferation is more useful than simply listing individual feedbacks. The critical issue is not the existence of one feedback, but the rapidly expanding number of ways in which feedbacks can connect.
The Feedbacks Are Accelerating
Acceleration is particularly important because a climate system experiencing a given external forcing does not necessarily produce a constant rate of response. If feedbacks strengthen as warming increases, the response itself can accelerate. This creates a fundamental distinction between a linear response—forcing → proportional response—and a coupled nonlinear response in which forcing → response → feedback → stronger response → stronger feedback → acceleration.
This acceleration is increasingly visible in observations. Ocean heat has accumulated to extraordinary levels, marine heatwaves are becoming more intense and persistent, Arctic warming is occurring at multiple times the global average rate, Greenland is losing ice mass, Antarctica is losing ice mass, permafrost is thawing, extreme precipitation is intensifying as a warmer atmosphere carries more moisture, heat extremes are becoming more severe, and drought and wildfire are degrading major carbon-storing ecosystems.
These are not simply independent records of a warming planet. They are evidence of a planet whose internal responses are becoming increasingly consequential. The critical observation is not merely that each indicator is changing, but that multiple indicators are changing simultaneously across interconnected subsystems, with some changes occurring at accelerating rates. That is a signature of a system becoming increasingly nonlinear.
Water Vapor: The Fastest Amplifier
The water-vapor feedback demonstrates how rapidly a positive feedback can operate. Water vapor is the most abundant greenhouse gas in Earth’s atmosphere and provides one of the strongest and fastest positive feedbacks in the climate system. The Clausius–Clapeyron relationship indicates that the atmosphere can hold approximately 7% more water vapor for every 1°C of warming, assuming relative humidity remains broadly similar.
The sequence is straightforward: warming → increased atmospheric moisture → stronger greenhouse trapping → additional warming ↺. Water vapor does not provide the original forcing; it amplifies it. This feedback operates rapidly, on timescales ranging from days to weeks, and affects the entire atmospheric system. A warmer atmosphere also means that when moisture is transported into storm systems, more water can potentially be released as extreme precipitation. The same thermodynamic process that increases atmospheric heat retention can therefore contribute to more intense precipitation extremes, allowing one feedback to influence multiple hazards.
Ice–Albedo: The Arctic Heat Engine
The cryosphere provides another rapidly reinforcing feedback. Snow and ice reflect incoming solar radiation, while dark ocean and land surfaces absorb it. As Arctic ice disappears, the sequence becomes ice loss → reduced albedo → increased solar absorption → regional warming → additional ice loss ↺.
The Arctic is therefore not simply responding to global warming; it is increasingly participating in the amplification of regional warming. This is particularly important because Arctic amplification alters the temperature contrast between the poles and lower latitudes. That contrast is one of the fundamental drivers of atmospheric circulation, meaning that changes in the polar temperature structure can propagate outward into the mid-latitude atmosphere. The feedback does not stop at the Arctic. It travels.
Permafrost: The Carbon Feedback
Permafrost represents a slower but potentially persistent feedback. Frozen northern soils contain enormous quantities of organic carbon accumulated over thousands of years. When those soils thaw, microorganisms gain access to previously frozen organic matter. Depending on environmental conditions, decomposition releases carbon dioxide and methane.
The sequence is therefore warming → thaw → decomposition → greenhouse-gas release → additional warming ↺. Unlike water vapor, this feedback can continue long after the initial warming event, making it a potential bridge between short-term climate acceleration and long-term carbon-cycle destabilization.
Boreal Forests: From Carbon Sink to Carbon Stress
Boreal forests are increasingly exposed to compound stress from heat, drought, insects, disease, and wildfire, with these stresses capable of interacting rather than simply occurring independently. A forest weakened by drought becomes more vulnerable to fire, fire releases stored carbon, and the loss of forest cover reduces future carbon uptake. The resulting feedback is warming → drought + fire → forest degradation → reduced carbon uptake + carbon release → additional atmospheric warming ↺.
The significance lies in the possibility of a transition from a carbon-absorbing ecosystem toward one that increasingly contributes carbon to the atmosphere. That transition would not be instantaneous, nor would it occur uniformly across the boreal zone, but the direction of the feedback is clear: increasing climate stress can progressively weaken an important carbon sink.
Amazon: The Rainfall-Recycling Feedback
The Amazon provides an even more tightly coupled example because the forest does not merely receive rainfall; it helps generate and recycle it. Through evapotranspiration, vegetation transfers enormous quantities of water back into the atmosphere. Repeated drought and heat stress can weaken this mechanism, creating a potentially dangerous feedback: warming → drought → forest stress → reduced evapotranspiration → reduced rainfall recycling → greater drought → forest degradation → carbon release ↺.
The forest therefore becomes both a victim and a participant in the warming process. The more the ecosystem is degraded, the more its ability to sustain the hydrological processes on which it depends can be compromised, while the carbon released through degradation and fire can add further greenhouse forcing.
The Comingling Cascade
When these systems are considered together, the emerging picture is fundamentally different from a simple list of tipping points. It can be represented as a connected cascade:
This is no longer adequately described as a series of isolated tipping points. It is a tipping cascade, and the cascade is capable of feeding back into itself.
The Speed of the System Is Changing
This may be the most important implication. The climate system is not simply moving toward a warmer equilibrium; it is increasingly exhibiting faster transitions between states. Heat accumulates, ice responds, water vapor amplifies, atmospheric circulation reorganizes, extreme precipitation intensifies, drought stresses ecosystems, wildfire releases carbon, permafrost thaws, and ocean circulation responds. Each process operates on a different timescale, but those timescales overlap, and that overlap creates opportunities for comingling.
A slow process such as ice-sheet destabilization can interact with a faster process such as atmospheric circulation. A seasonal event such as El Niño can temporarily push a slower-moving tipping element toward a threshold. A wildfire can rapidly convert a carbon sink into a carbon source, while a marine heatwave can stress an ecosystem already weakened by long-term warming. The climate system therefore contains multiple clocks, and as warming increases, those clocks increasingly begin to interact.
A New Way of Thinking About 1.5°C
The importance of 1.5°C is therefore not that crossing it suddenly turns the climate system into something entirely different. Its importance is that it places an increasing number of interconnected systems into a zone of elevated vulnerability. The relevant question is not simply whether we crossed 1.5°C, but how many systems are now being pushed toward critical states, how strongly those systems are interacting, whether their feedbacks are strengthening, and whether the rate of change is increasing.
Most importantly, we must ask whether we are beginning to see the Earth system respond to itself.
There is growing evidence that the answer is yes. Human emissions remain the primary driver of contemporary global warming, but the climate system does not remain passive after that forcing occurs. It responds. That response creates feedback. Feedback creates amplification. Amplification changes the conditions experienced by other systems. Those systems respond, and their responses feed back again.
That is the central danger of comingling tipping points.
From Tipping Points to Tipping Point Season
The old conceptual model was relatively simple: human emissions → warming → impacts. The emerging model is more complicated: human emissions → warming → tipping-element stress → feedback activation → system interaction → amplification → additional warming and disruption → additional feedback activation.
The Earth system is becoming an active participant in the trajectory we have initiated. This does not mean that climate change has become independent of human emissions. It means that the consequences of those emissions are increasingly being amplified by the physical and biological systems they have destabilized.
That is why the distinction between climate forcing and climate response is becoming increasingly important. We are no longer dealing solely with the question of how much additional warming humans will cause. We must also contend with how much additional change the warming already imposed can generate through Earth-system feedbacks.
That is the beginning of Tipping Point Season: not a season defined by one spectacular threshold, but a season defined by comingling—multiple tipping elements, multiple feedbacks, multiple timescales, multiple cascading pathways, and an increasingly observable acceleration in the response of the Earth system.
The greatest danger may therefore not be that one tipping point suddenly topples, but that several have already begun moving together. Tipping points are beginning to come together, feedbacks are proliferating, interactions are strengthening, and acceleration is emerging across interconnected Earth-system components. The climate system is consequently beginning to change faster and in more complex ways than its individual pieces can be understood in isolation.
That is the climate challenge we now face: not simply tipping points, not simply feedbacks, but tipping points comingling and feedbacks accelerating one another.
🌎 TIPPING POINT SEASON: HUNTING FOR POLAR ICE Subtitle: Tipping Points Comingling
What happens when the planet crosses the 1.5°C tripwire and multiple climate systems are already under stress?
We’re beginning to find out.
The polar regions are sending some of the clearest signals. Arctic sea ice is shrinking and thinning, amplifying warming through the albedo feedback. In Antarctica, warmer ocean water is attacking vulnerable ice shelves from below through basal melting, weakening the buttresses that slow the flow of land-based ice into the ocean.
But the bigger concern isn’t any single tipping point.
It’s what happens when they start interacting.
Polar ice loss means more than melting ice. It means changes in albedo, freshwater input, ocean heat, atmospheric circulation, and eventually the systems that regulate rainfall and ecosystems around the planet.
The links exist. The feedbacks are physically real. And they already are interacting.
The question is no longer whether these feedbacks will interact, but how strongly they will amplify one another.
This is why I’m calling this Tipping Point Season.
We’re not simply watching the ice melt.
We’re hunting for evidence that the climate system is beginning to behave differently.
Polar Ice Colllapse
The first sustained period in which global temperatures repeatedly exceeded 1.5°C above the pre-industrial baseline occurred during the extraordinary heat of 2023–2024. The significance of 1.5°C is not simply the number itself. It is what happens to the Earth system as warming pushes individual components toward critical thresholds.
At approximately this level of warming, multiple climate tipping elements become increasingly vulnerable. Ice sheets destabilize. Permafrost thaws. Ocean circulation weakens. Tropical forests lose resilience. Coral reefs approach thermal limits. These systems do not operate independently. Once one begins to change, it can alter the conditions experienced by another. Feedbacks become coupled, tipping elements begin to interact, and the result can be a system in which climate change no longer progresses linearly with the forcing imposed by human emissions. It accelerates.
That is the danger of a tipping point season. And the polar regions are at the head of the parade.
2023–2024: The Ice Begins to Behave Differently
The Antarctic cryosphere provided one of the clearest warnings.
During 2023, Antarctic sea ice reached an extraordinary low. The February 2023 summer minimum was the lowest in the satellite record, followed by a September winter maximum that was also a record low. The loss was not simply a matter of seasonal variability. The magnitude of the departure raised the possibility that Antarctic sea ice was entering a fundamentally different regime.
The anomaly continued into 2024. Antarctic sea ice reached a winter maximum of approximately 17.16 million square kilometers on September 19, 2024, the second-lowest maximum in the 46-year satellite record. Two consecutive years of exceptionally low sea ice suggested that the system was capable of occupying a state substantially different from the historical range in which it had operated for decades.
A regime shift does not mean Antarctic sea ice suddenly disappears forever. It means that the statistical behavior of the system changes. Extremes that were once rare can become more common, recovery can become less complete, and the system can begin fluctuating around a new baseline.
This distinction is critical because sea ice and land ice are not the same thing. Sea ice floats and primarily affects albedo, ocean-atmosphere exchanges, and regional climate dynamics. The Antarctic ice sheet is land-based, and when it loses mass, that water ultimately contributes to global sea-level rise.
The Antarctic ice sheet continued to lose mass even as regional snowfall temporarily offset some losses, particularly in East Antarctica. The fundamental concern remains concentrated in West Antarctica, where warm ocean water can attack ice shelves from below. The stability of the ice sheet therefore depends not simply on how much snow falls on its surface, but on the interaction among ocean temperatures, ice shelves, grounding lines, glacier flow, atmospheric circulation, and the geometry of the Antarctic continental shelf.
The Arctic was changing at the same time.
The September 2023 Arctic sea-ice minimum was approximately 4.23 million square kilometers, the sixth-lowest minimum in the satellite record. More importantly, the Arctic has lost much of its older, thicker multiyear ice. The remaining ice is younger and thinner, making it more vulnerable to subsequent warming and summer melt.
The thinning of the Arctic ice cover is especially important because thickness represents stored resilience. Ice that is only a fraction of its former thickness can disappear much more rapidly under the same atmospheric and oceanic forcing. The Arctic is therefore not simply losing ice. It is losing ice resilience.
The delayed autumn freeze-up adds another feedback. When open ocean remains exposed later into the year, it absorbs additional solar energy and releases additional heat into the atmosphere during the cold season. Less ice means more exposed dark ocean. More exposed dark ocean means more absorbed energy. More stored heat can delay refreezing. The result is a feedback loop that reinforces the original loss.
2026–2027: A Much Stronger El Niño Meets a Changed Cryosphere
The next phase of the experiment is already underway.
The 2026–2027 El Niño has rapidly intensified, with NOAA identifying a substantial probability of an historically exceptional event. The World Meteorological Organization has likewise described the developing event as very strong, with the likelihood of persistence through the Northern Hemisphere winter approaching certainty.
The significance is not simply that El Niño produces global warmth. It is that this El Niño is occurring against a cryosphere that has already been altered by decades of warming.
This is the experiment nature is conducting: What happens when an exceptionally strong El Niño encounters an already destabilized cryosphere?
The answer will depend on the interaction of multiple systems. El Niño changes atmospheric circulation, precipitation patterns, ocean temperatures, and the distribution of heat around the planet. The polar regions respond to those changes through complex atmospheric and oceanic pathways.
In Antarctica, El Niño can interact with the Amundsen Sea Low and atmospheric circulation patterns that influence the transport of warm, moist air toward West Antarctica and the Antarctic Peninsula. At the same time, changes in ocean circulation can transport relatively warm water onto continental shelves, where it can reach the undersides of floating ice shelves.
That basal melting is particularly dangerous because ice shelves act as buttresses. They help restrain the inland flow of glaciers. When they thin, fracture, or retreat, that buttressing effect can weaken. Glaciers such as Thwaites and Pine Island can then accelerate, increasing the rate at which land-based ice enters the ocean.
The result is a potential chain reaction: warmer ocean water promotes ice-shelf melting; weakened ice shelves provide less resistance to glacier flow; faster glacier flow causes grounding-line retreat; and grounding-line retreat can expose thicker ice to ocean water, potentially accelerating further retreat.
The Arctic is simultaneously being subjected to another set of interacting forces. El Niño can influence planetary-scale atmospheric waves and the distribution of heat between the tropics and higher latitudes. During the winter of 2026–2027, changes in the polar vortex could further alter the exchange of cold Arctic air and warmer mid-latitude air.
The resulting pattern can produce extreme weather whiplash: unusually warm conditions in the Arctic occurring alongside severe cold outbreaks farther south, or abrupt transitions between contrasting weather regimes. These events are not necessarily evidence of a single simple cause. They are manifestations of a climate system whose circulation is being reorganized by increasing energy and altered temperature gradients.
The question is not simply whether 2027 becomes the hottest year ever recorded. The more important question is whether the combined forcing produces persistent state changes in the cryosphere.
A record year can be followed by a cooler year. A record low can recover. But if the system repeatedly establishes new extremes without returning to its former state, something more fundamental may be occurring.
Tipping Points Comingling
The most important characteristic of climate tipping points is that they do not have to wait for one another.
A tipping element does not necessarily need to completely collapse before it begins affecting another system. A weakening ice sheet can alter freshwater input. Freshwater can alter ocean circulation. Ocean circulation can change atmospheric circulation and rainfall. Rainfall changes can stress tropical forests. Forest loss can release carbon. Carbon release can increase warming and place additional stress on ice, permafrost, and ecosystems.
This is where tipping points begin comingling.
Consider the Atlantic Meridional Overturning Circulation, or AMOC. Large-scale melting of Greenland and other ice reservoirs adds freshwater to the North Atlantic. Freshwater makes surface water less dense and can interfere with the sinking of cold, salty water that helps drive the overturning circulation.
A weakened AMOC can then alter heat transport and atmospheric circulation. It can shift rainfall patterns, including the position and strength of the Intertropical Convergence Zone, or ITCZ. That creates the possibility of major consequences for tropical rainfall, including rainfall over the Amazon basin.
The Amazon is particularly important because it is not simply a passive victim of climate change. It is part of the climate system itself. Forests recycle enormous quantities of water through evapotranspiration. When drought, heat, deforestation, and altered rainfall reduce forest resilience, that moisture-recycling system can weaken.
The sequence becomes self-reinforcing: AMOC weakening alters atmospheric circulation; atmospheric circulation alters rainfall; reduced rainfall increases Amazon drought stress; drought and heat increase forest mortality; forest loss reduces moisture recycling and releases carbon; additional carbon increases atmospheric warming; and additional warming further stresses the forest.
Under severe conditions, Amazon dieback could release enormous quantities of stored carbon, potentially on the order of 140 gigatons of carbon. That would transform the Amazon from a major carbon sink into an additional source of atmospheric carbon.
The same principle applies in the Arctic.
Loss of sea ice reduces the reflective surface of the planet. Dark ocean absorbs more solar radiation than bright sea ice. That additional absorbed energy contributes to Arctic amplification, which increases regional warming. Warmer Arctic conditions accelerate permafrost thaw.
Permafrost contains enormous quantities of organic carbon accumulated over thousands of years. As frozen ground thaws, microbial activity can release carbon dioxide and methane. Those greenhouse gases increase atmospheric warming, which promotes further permafrost thaw.
The feedback therefore becomes another amplification loop: ice loss increases absorbed energy; absorbed energy increases warming; warming thaws permafrost; thaw releases greenhouse gases; greenhouse gases increase warming; and warming drives additional ice loss.
West Antarctica presents another powerful feedback.
Warm ocean water reaches the underside of ice shelves. Ice shelves thin. Their buttressing effect declines. Glaciers accelerate. Grounding lines retreat. As grounding lines retreat into deeper water, the geometry of the ice sheet can become increasingly unstable.
This is the fundamental concern behind marine ice-sheet instability. Once retreat becomes self-sustaining, the loss of West Antarctic ice could continue for centuries even if atmospheric temperatures eventually stabilize. The ultimate consequence would be meters of global sea-level rise.
Coral reefs provide another example of interacting stresses. Rising ocean temperatures produce increasingly frequent and severe marine heatwaves, while increasing atmospheric carbon dioxide drives ocean acidification. Heat stress causes coral bleaching and mortality, while acidification makes it more difficult for corals to build and maintain their skeletons.
These stresses do not simply add together. They compound one another.
The Emerging Cascade
The larger system can therefore be represented as a chain of interacting feedbacks:
POLAR ICE LOSS → ALBEDO LOSS + FRESHWATER INPUT + OCEAN WARMING → ARCTIC AMPLIFICATION + AMOC WEAKENING → ATMOSPHERIC CIRCULATION CHANGE → ITCZ / MONSOON DISRUPTION → AMAZON DROUGHT + DIEBACK → CARBON RELEASE → ADDITIONAL GLOBAL WARMING → PERMAFROST THAW + CORAL COLLAPSE + FURTHER ICE LOSS
The Earth system contains multiple interacting feedbacks capable of reinforcing one another. As global warming increases, the probability that these feedbacks interact also increases.
That changes the way we should interpret climate extremes. The critical signal may not be the next record. It may be the failure to recover from the last one. A single extreme can be weather. Repeated extremes can become climate. Persistent extremes can indicate a regime shift.
We are therefore not simply watching individual records being broken. We are watching whether the underlying system continues to return toward its previous state after each disturbance.
The links exist. The feedbacks are physically real. And as warming increases, the probability that several of them interact increases as well. They already are interacting. The question is no longer whether these feedbacks will interact, but how strongly they will amplify one another.
We are not simply watching the ice melt. We are watching to see whether the climate system can still return to its previous state.
It is no longer enough to ask: How much warming are humans causing?
The more consequential question becomes: How much additional warming is the Earth system beginning to cause for itself?
That is the real meaning of a tipping point season.
And right now, we are hunting for the answer in the ice.
What if the most important sign of a climate tipping point isn’t the tipping point itself—but the way the rest of the planet begins to respond?
The paper, “Tipping Point Season: See the AMOC Sea,” looks at the increasingly interconnected behavior of the Pacific, Atlantic, North Atlantic, and atmosphere.
The developing 2026–2027 climate configuration—Pacific El Niño alongside Atlantic Niña—offers a striking example of how climate energy can be rerouted across ocean basins through the atmosphere.
Pacific warming changes convection.
The atmosphere reroutes energy.
Atlantic winds change.
Upwelling increases.
The tropical Atlantic cools.
And the North Atlantic circulation is part of that same planetary system.
That matters because the AMOC is not an isolated climate component. Its disruption can interact with Greenland melt, ocean stratification, atmospheric circulation, ENSO, the NAO, and other feedback mechanisms.
This is what makes this Tipping Point Hunting Season different.
The AMOC disruption is becoming more noticeable—not necessarily because there is one dramatic moment of collapse, but because its fingerprints are increasingly visible in the behavior of the systems connected to it.
We may be moving from a climate system where tipping points can be studied individually toward one where the critical question is how they interact.
One ocean warms.
Another cools.
The atmosphere responds.
The circulation changes.
The feedbacks respond.
And the planet adjusts.
We are not hunting for one tipping point.
We are watching the connections between them.
🌎 ONE PLANETARY SYSTEM
How a Pacific El Niño Can Reroute Climate Energy Across the Planet
The first time the global temperature was sustained above 1.5°C was during the 2023–2024 El Niño. The reason 1.5°C is critical is its potential tripwire effect. It is a temperature level at which feedbacks can become self-reinforcing and begin coupling with other tipping points and feedback mechanisms.
The 2023–2024 Season
1. The Dynamic Influence Is Primarily Reversed
Recent climate modeling demonstrates that the directional influence is actually the opposite of what might be assumed: a weakening Atlantic Meridional Overturning Circulation (AMOC) actively strengthens El Niño variability.
As the AMOC slows because of global warming, it reduces the annual sea-surface-temperature cycle in the eastern equatorial Pacific. This amplifies ENSO (El Niño–Southern Oscillation) variability by roughly 11% and shifts the pattern toward more frequent Central Pacific El Niño events.
2. Atmospheric Teleconnections
The 2023–2024 El Niño altered the global zonal Walker circulation. This shift can affect the North Atlantic Oscillation (NAO) through large-scale atmospheric loops.
Because the NAO heavily influences wind patterns and winter temperatures over the North Atlantic, these El Niño-driven atmospheric shifts can indirectly modulate the surface currents that feed the AMOC.
3. Compounding Global Marine Stress
The 2023–2024 El Niño was the fifth-most powerful on record and temporarily drove global temperatures to unprecedented highs.
It stacked massive amounts of heat on top of an Atlantic basin that was already experiencing severe marine heatwaves. This extreme global warmth contributes to accelerated melting of the Greenland Ice Sheet and increased northern rainfall.
The resulting massive influx of buoyant freshwater dilutes the salinity of the North Atlantic, preventing water from sinking and pushing the AMOC closer to its projected tipping point.
The 2026–2027 Season
The simultaneous occurrence of an extreme Pacific Super El Niño and an anomalous Atlantic Niña represents a significant disruption of historically observed ocean–atmosphere interactions.
These coupled climate anomalies illustrate how anthropogenic warming is altering the baseline state of Earth’s climate system, reducing predictability, amplifying hydroclimatic extremes, and accelerating interconnected feedback mechanisms.
While an Atlantic Niña pattern may temporarily suppress Atlantic hurricane activity through increased atmospheric stability and wind shear, this short-term effect masks deeper systemic changes occurring within global ocean circulation, carbon cycling, and energy redistribution.
Climate change is increasingly modifying the physical conditions under which natural climate oscillations such as El Niño–Southern Oscillation (ENSO) and Atlantic Niño variability operate.
Warmer ocean surfaces, enhanced stratification, declining vertical mixing, and changing circulation patterns are transforming previously stable climate relationships into increasingly nonlinear and difficult-to-predict interactions.
These changes threaten to intensify global precipitation extremes, weaken ocean carbon sequestration, and accelerate reinforcing feedback loops involving greenhouse gas emissions, ocean warming, and cryosphere loss.
The currently developing El Niño exemplifies the supercharged climate energy accumulating in the system.
The 2026 ocean–atmosphere configuration illustrates how climate variability can interact with long-term warming trends to activate reinforcing feedback mechanisms.
A simplified representation is:
Ocean Warming
↓
Stronger Stratification
↓
Reduced Mixing
↓
Increased Greenhouse Gas Release
↓
Accelerated Warming
↓
Further Ocean Warming
These feedbacks transform climate change from a linear response into a nonlinear system in which small perturbations can trigger increasingly larger consequences.
Rerouting the Walker Circulation:
The Pacific El Niño–Atlantic Niña Atmospheric Bridge
The unusual co-occurrence of a Pacific El Niño and an Atlantic Niña illustrates how strongly connected Earth’s climate system is.
Although the Pacific and Atlantic are separate ocean basins, the atmosphere links them through planetary-scale circulation patterns.
One of the most important connections is the Walker circulation—a vast east–west circulation of rising and sinking air across the tropics.
When El Niño warms the central and eastern tropical Pacific, it reorganizes convection, atmospheric pressure, and wind patterns across the tropics. Those changes can extend into the Atlantic, altering the trade winds and ocean circulation there.
The result is a remarkable sequence of interconnected processes:
The Walker circulation is a large-scale tropical atmospheric circulation that links changes in convection, pressure, winds, and ocean–atmosphere heat exchange across the Pacific and beyond.
During El Niño, changes in Pacific sea-surface temperatures reorganize this circulation, creating atmospheric teleconnections that can extend into the Atlantic.
Pacific Warming
During El Niño, unusually warm surface waters develop across the central and eastern tropical Pacific.
The additional oceanic heat increases evaporation and fuels stronger deep atmospheric convection.
Shifted Convection
As warm, moisture-rich air rises over the anomalously warm Pacific, the center of tropical convection shifts eastward.
This changes the pattern of rising and sinking air that defines the Walker circulation, redistributing atmospheric energy and altering pressure and wind patterns across the tropics.
Atlantic Subsidence
The reorganized tropical circulation can produce compensating regions of sinking, relatively dry air over parts of the tropical Atlantic and Caribbean.
This subsidence suppresses cloud formation and deep convection and can contribute to higher surface pressure.
The Atmospheric Bridge
The Pacific warming does not directly “cause” the Atlantic to cool.
Instead, ENSO reorganizes the atmospheric circulation, and that planetary-scale response can alter Atlantic pressure, winds, evaporation, and ocean circulation—providing the atmospheric bridge between the two ocean basins.
2. The Planetary Teleconnection:
From the Pacific to the Atlantic and Beyond
The ENSO teleconnection does not stop at the Atlantic.
The atmospheric disturbance generated by El Niño can propagate across the tropics and into the extratropics, linking the Pacific to the Atlantic, North Atlantic, Europe, and the United Kingdom through a network of atmospheric circulation patterns.
As tropical convection shifts over the Pacific, it alters the distribution of atmospheric heating.
These changes can generate large-scale Rossby waves that propagate through the atmosphere, modifying the position and strength of the jet streams, storm tracks, and persistent pressure systems far from the original Pacific anomaly.
Pacific → Atlantic
The first major connection is the tropical Atlantic:
Pacific El Niño
↓
Shifted tropical convection
↓
Walker circulation response
↓
Changes in tropical pressure and winds
↓
Atlantic trade-wind response
↓
Ocean circulation and sea-surface-temperature changes
This atmospheric bridge helps explain how a warming anomaly in the Pacific can coincide with cooling in the tropical Atlantic.
Atlantic → North Atlantic → Europe
The teleconnection can extend farther north.
Changes in tropical heating and atmospheric wave patterns can influence the North Atlantic jet stream and pressure fields, including variations associated with the North Atlantic Oscillation (NAO).
These changes can alter the path of Atlantic storms and the transport of heat and moisture toward Europe.
The United Kingdom sits downstream of this North Atlantic circulation and can therefore experience changes in the probability of particular weather regimes—even though the original oceanic disturbance began thousands of miles away in the tropical Pacific.
The relationship is probabilistic, not deterministic.
ENSO is one influence among many, and the eventual European response depends on the season, the state of the North Atlantic, stratospheric conditions, and other interacting climate modes.
A Planetary Feedback Network
The important point is that this is not a simple one-way pipeline.
PACIFIC
El Niño
↓
ATMOSPHERE
Walker circulation + planetary waves
↓
ATLANTIC
Trade winds + ocean response
↓
NORTH ATLANTIC
Jet stream + NAO
↓
EUROPE / UK
Weather-pattern response
↓
GLOBAL OCEAN–ATMOSPHERE SYSTEM
↓
PACIFIC
The final connection back toward the Pacific should not be interpreted as a single atmospheric current literally traveling around the planet.
Instead, it represents coupled feedbacks within the global climate system.
Changes in one ocean basin alter atmospheric circulation; those atmospheric changes affect other ocean basins and land surfaces; and those changes can subsequently feed back into the global circulation system.
ENSO is therefore not simply a Pacific phenomenon.
It is a planetary-scale disturbance that can reorganize atmospheric and oceanic conditions across multiple basins and continents.
One ocean warms.
The atmosphere responds.
The response travels.
The planet adjusts.
3. Amplification of Atlantic Trade Winds
Pressure Gradients
The redistribution of rising and sinking air modifies sea-level pressure across the tropical Atlantic.
A stronger pressure gradient can develop along the equatorial Atlantic.
Stronger Easterly Winds
The resulting pressure gradient can strengthen the Atlantic trade winds.
These persistent easterlies are critical because they directly interact with the ocean surface.
The atmosphere has effectively rerouted part of the Pacific’s excess energy through a planetary-scale circulation response, creating conditions that can cool a distant ocean basin.
4. Wind-Driven Ocean Upwelling
Surface-Water Displacement
Stronger easterly trade winds push warm surface waters westward across the equatorial Atlantic and alter the distribution of ocean heat.
Cold Water Rises
As surface waters are displaced, deeper, colder water can rise toward the surface through equatorial upwelling.
This water is typically cooler and richer in nutrients than the surface layer.
The Atlantic Niña Emerges
When the resulting cooling is sufficiently strong and persistent, tropical Atlantic sea-surface temperatures can fall substantially below normal, producing the characteristic cold anomaly known as an Atlantic Niña.
The Atlantic cooling is therefore not an isolated ocean event.
It can be part of a larger coupled atmosphere–ocean response initiated thousands of miles away in the Pacific.
The Atmospheric Shield:
A Planetary Teleconnection Comes Full Circle
When a Pacific El Niño and an Atlantic Niña occur together, their effects can reinforce one another over the tropical Atlantic.
But the hurricane response is only one part of a much larger planetary circulation story.
The sequence begins thousands of miles away:
Pacific El Niño
↓
Rerouted Walker circulation
↓
Planetary atmospheric teleconnection
↓
Atlantic pressure + wind changes
↓
Stronger trade winds
↓
Enhanced equatorial upwelling
↓
Atlantic Niña / cooler tropical Atlantic
The resulting Atlantic conditions can then influence tropical cyclone development.
El Niño tends to increase vertical wind shear, disrupting the organization of developing tropical cyclones.
At the same time, cooler tropical Atlantic waters reduce the oceanic heat available to support deep convection and storm intensification.
Together, these effects can create an atmospheric shield over the Atlantic hurricane-development region:
ATLANTIC NIÑA
Cooler ocean
↓
Less convective energy
EL NIÑO
Pacific warming
↓
Stronger vertical wind shear
↓
COMBINED EFFECT
↓
Less favorable conditions for Atlantic tropical cyclones
This does not mean an Atlantic hurricane season becomes impossible.
Tropical cyclone activity depends on many interacting factors, including sea-surface temperatures, atmospheric moisture, vertical wind shear, African easterly waves, upper-level circulation, and broader Atlantic climate conditions.
One Planetary System
What makes this Tipping Point Hunting Season different is that the connections between climate systems are becoming increasingly visible.
The AMOC is no longer something happening quietly in the background of the climate system. Its disruption is beginning to show up through the behavior of the systems connected to it. The weakening of the AMOC can alter the conditions that shape ENSO variability, while El Niño can reorganize atmospheric circulation that reaches back into the North Atlantic. Greenland melt and increased northern rainfall add freshwater to the North Atlantic, further affecting the density and sinking of seawater that helps drive the AMOC.
This is the critical distinction between looking for individual tipping points and watching the climate system itself.
A tipping point does not necessarily announce itself as one spectacular event. It can emerge as a growing loss of stability—a system that responds differently than it once did, feedbacks that begin reinforcing one another, and formerly separate climate oscillations that increasingly interact.
The 2026–2027 Pacific El Niño–Atlantic Niña configuration provides another window into that process. The Pacific, Atlantic, North Atlantic, and atmosphere are not operating independently. Energy is being redistributed among them through circulation, pressure, winds, ocean mixing, heat storage, and freshwater fluxes.
And that brings us back to the AMOC.
The AMOC is not merely another potential tipping point waiting somewhere in the future. It is part of the circulation architecture connecting the climate system together. As that circulation is disrupted, the consequences can propagate outward—changing ocean temperatures, atmospheric circulation, storm tracks, precipitation patterns, and the behavior of other climate modes.
That is why the AMOC disruption is much more noticeable in this Tipping Point Hunting Season.
We are beginning to see the fingerprints of a changing circulation system in places that, at first glance, appear unrelated.
A Pacific ocean anomaly can alter the atmosphere. The atmosphere can alter the Atlantic. The Atlantic can alter the North Atlantic. The North Atlantic can influence Europe. Freshwater entering the North Atlantic can further disrupt the circulation that connects these systems. And the resulting changes can feed back into the system again.
This is not a collection of separate climate problems. It is a coupled system increasingly operating outside the conditions under which we learned to understand it.
The important question, therefore, is no longer simply:
“Which tipping point are we approaching?”
It is:
“What happens when tipping points begin interacting?”
That is the essence of Tipping Point Hunting Season. We are not hunting for a single point on a graph. We are watching for the moment when the connections between the points become impossible to ignore.
One ocean warms.
Another cools.
The atmosphere reroutes the energy.
The circulation changes.
The feedbacks respond.
And the planet adjusts.
The AMOC is one of the clearest places to watch that adjustment happening.
Coatesville, PA: Hydroclimatic Whiplash — Dying of Thirst in a Flood
The climate problem can arrive through your water tap.
Pennsylvania American Water issued a mandatory water conservation order on Sunday, September 6, 2026, affecting approximately 23,000 customer connections across the Coatesville water system.
Residents were ordered to reduce water consumption by 10% to 15% and temporarily limit their use of water to essential purposes. The affected system includes Coatesville, Atglen, Parkesburg, South Coatesville and surrounding communities in Chester and Lancaster counties.
At first glance, a mandatory water conservation order sounds like a drought story.
It isn’t.
This is something more revealing:
There was too much water—arriving too quickly—and the water system could not process it normally.
Pennsylvania American Water reported that recent weather-related changes in local water sources increased the amount of treatment required at the plant, placing additional demand on filtration systems and temporarily reducing treatment capacity.
The result is a striking example of hydroclimatic whiplash:
You can have water everywhere and still have a water shortage.
WHAT IS HYDROCLIMATIC WHIPLASH?
Hydroclimatic whiplash occurs when the hydrologic system swings rapidly between extremes—such as drought and intense rainfall, low flows and flooding, or water scarcity and overwhelming runoff.
The important point is that these extremes do not have to occur months or years apart. The transition itself can become the problem. A landscape stressed by heat and dry conditions can suddenly receive intense rainfall. Instead of that rainfall becoming a stable supply of usable water, much of it can move rapidly across the landscape and into streams. That runoff can carry sediment, organic material and other substances into the water supply.
The result is paradoxical:
The landscape is flooded with water while the community is told to conserve water.
This is not a contradiction in the physics.
It is a consequence of the difference between water being present and water being available as reliable, treated drinking water.
HOW IS CLIMATE ENERGY HITTING YOU?
This is where the Coatesville event becomes more than a local water-system story.
Climate change is fundamentally an energy problem.
A warmer atmosphere and warmer land surface alter evaporation, atmospheric moisture, precipitation intensity and the movement of water through the hydrologic cycle. That additional energy does not simply produce “more rain” or “less rain.” It can produce greater volatility.
Longer dry periods can increase the amount of moisture available to the atmosphere when moisture eventually returns. Heavy precipitation can then arrive in concentrated bursts, producing rapid runoff rather than a gradual recharge of soils, groundwater and reservoirs.
Heat increases evaporation from soils, vegetation and surface waters. A warmer atmosphere can also hold more water vapor. That matters because precipitation is not simply a question of whether clouds exist. It is a question of how much moisture and energy are available when atmospheric conditions produce rainfall.
A warmer climate therefore changes the hydrologic operating environment. The atmosphere becomes capable of moving larger quantities of water through the system. But that water does not necessarily arrive when or where communities need it.
2. THE SECOND HIT: RAIN ARRIVES AS A SHOCK
Heavy rainfall can overwhelm the landscape’s ability to absorb water. Instead of slowly infiltrating into soil and groundwater, water rapidly becomes runoff. Streams rise. Banks overflow. Sediment is mobilized. Organic material is flushed from the watershed.
The same rain that looks like an enormous addition to the regional water supply can therefore create an immediate problem for the water-treatment system.
This distinction is crucial:
Floodwater is not drinking water.
A reservoir or stream can contain enormous quantities of water while the fraction that can be economically and reliably converted into potable water temporarily falls.
3. THE THIRD HIT: WATER QUALITY BECOMES WATER AVAILABILITY
This is where the Coatesville event becomes particularly important. Pennsylvania American Water did not announce the conservation order because its customers suddenly consumed all the available water. The problem was that weather-related changes in local water sources increased the treatment burden and temporarily reduced the plant’s treatment capacity. That means the limiting factor shifted. The community did not necessarily run out of water. It encountered a temporary shortage of treatable water capacity. That distinction is becoming increasingly important in a changing climate.
Water infrastructure is engineered around expected ranges of conditions. But when the conditions themselves become more volatile, the infrastructure can be stressed from both directions.
Too little water can be a problem.
Too much water can also be a problem.
And rapid movement between the two can be worse still.
THE INFRASTRUCTURE PROBLEM
Most water systems were designed around historical hydrologic patterns. Treatment facilities have specific capacities. Filtration systems have operating limits. Pumping systems have design requirements. Reservoirs and intakes are built around expected ranges of water quantity and quality. But climate change changes the conditions under which these systems operate.
A treatment plant does not care whether the water arriving at its intake is technically “more water.” It cares about whether that water can be processed reliably.
When a storm rapidly changes raw-water conditions, the plant may have to work harder to produce the same quantity of finished drinking water. And if treatment capacity temporarily falls below normal demand, conservation becomes a tool for balancing the equation.
That is precisely what happened in the Coatesville system.
THE PARADOX: FLOODING CAN CREATE WATER SCARCITY
This is perhaps the most important lesson from Coatesville.
We often think about water security in a simple equation:
Drought = not enough water.
But climate disruption creates a more complicated equation:
You can have enormous quantities of water and still have a water-security problem if:
the water arrives too quickly,
the water is contaminated with sediment or organic material,
treatment requirements suddenly increase,
filtration capacity becomes constrained,
infrastructure cannot process the incoming water,
or the timing of supply does not match the timing of demand.
This is why calling every water problem a “drought” misses part of the story.
The emerging problem is increasingly hydrologic instability.
FROM FLOOD TO FAUCET
The path from atmospheric energy to your kitchen faucet can be surprisingly short:
Climate energy
↓
More evaporation and atmospheric moisture
↓
Heavy precipitation
↓
Rapid runoff
↓
Sediment and organic material enter waterways
↓
Raw-water quality deteriorates
↓
Treatment requirements increase
↓
Filtration capacity is reduced
↓
Available treated-water supply falls
↓
Mandatory conservation
↓
You turn on the faucet—and climate change has arrived at your house.
This is what the “How Is Climate Energy Hitting You?” framework is designed to reveal.
Climate change does not always appear as a dramatic temperature record or a catastrophic storm.
Sometimes it appears as a notice from your water utility telling you to use less water because it just rained too much.
WHY THIS MATTERS BEYOND COATESVILLE
The Coatesville event is local. The underlying mechanism is not necessarily local.
As climate volatility increases, communities can increasingly experience combinations that historically seemed contradictory:
Drought and flooding.Water scarcity and extreme rainfall.Low groundwater and overflowing streams.Dry soils followed by flash flooding.Too much raw water and not enough treated water.
These are not mutually exclusive conditions. They can occur sequentially—or even simultaneously in different parts of the same watershed. That makes traditional definitions of “water availability” increasingly inadequate.
The question is no longer simply:
How much water do we have?
It is becoming:
Can we capture it, store it, treat it and deliver it when people need it?
THE CLIMATE-ENERGY CONNECTION
The deeper lesson is that climate change is altering the rate at which the hydrologic system operates. That rate matters. A gradual rainfall event gives soil, vegetation, streams, reservoirs and treatment systems time to respond. An extreme rainfall event compresses enormous amounts of water movement into a short period. The faster the system is forced to respond, the more likely it is that one component becomes the bottleneck.
That is why climate impacts increasingly need to be understood as dynamic systems problems, rather than isolated weather events.
The Coatesville treatment plant is one component. The watershed is another. The atmosphere is another. The community is another.
They are connected.
When the atmosphere changes the amount, intensity and timing of water entering the watershed, the consequences propagate through the entire system.
WHAT DOES THIS MEAN FOR YOU?
The practical lesson is simple:
Climate resilience is not only about preparing for drought.
It is about preparing for volatility. Water systems need to be capable of handling:
more intense rainfall
larger swings in streamflow
rapid changes in raw-water quality
higher treatment demands
temporary reductions in treatment capacity
and simultaneous pressure from heat, drought and population demand.
For residents, the impact can be surprisingly mundane. A conservation order. A water-use restriction. A warning from your utility. A temporary disruption in normal service. A higher infrastructure bill.
Or simply the realization that the water coming down from the sky cannot necessarily be converted into the water coming out of your faucet.
THE BIGGER PICTURE
Coatesville provides a remarkably clear example of why “How Is Climate Energy Hitting You?” begins with everyday systems rather than abstract global averages.
The atmosphere absorbs additional energy. That energy changes evaporation and atmospheric moisture. Rainfall becomes more extreme. Runoff becomes more abrupt. Water quality changes. Treatment becomes more difficult. Infrastructure reaches its operational limits. And the final consequence can be delivered directly to your home:
Use less water.
That is the climate signal. Not because the community is necessarily running out of water. But because the climate system has temporarily made the water harder to process.
Hydroclimatic whiplash in one sentence:
The same storm that puts too much water on the ground can temporarily leave a community with too little water it can safely deliver through the tap.
That is what happens when climate energy moves through a coupled atmosphere–watershed–infrastructure system.
And it is increasingly how climate change becomes personal.
Tonight’s homework assignment: How much land do I need for my own shit? (AKA The Eat n’ Poop Experiment)
Both literally and figuratively.
This is an experiment I’ve been working on for years. And when you actually try to do it—when you have to think about where your food comes from, where your water comes from, and what happens to everything that comes out of you—you gain a very different perspective.
And yes, sometimes the experiment even comes down to a question like: Do I eat the worm, or don’t I?
Food and water are big problems.
But getting rid of what comes out of you can be an even bigger problem.
I’ve been meeting quite a few other people who are “doing it”—trying to become more self-sufficient, reduce their dependence on centralized systems, and figure out what is actually required to sustain a human being.
So I thought a good test for me would be to reevaluate the whole concept at two scales:
Macro. And micro.
Tonight is micro night.
How many acres do you need for your own shit?
A commonly cited homesteading rule of thumb is roughly 2–5 acres per person for a fairly self-sufficient setup—but that’s not a universal number. It depends enormously on your diet, soil, climate, water supply, livestock, energy needs, and how much of your waste you can safely recycle.
And that’s where it gets interesting.
Food production: You might be able to produce a substantial amount of plant food on a fraction of an acre. Add grains, livestock, dairy, or meat, and the land requirement can increase dramatically.
Water: You need a reliable source of potable water—and potentially enough watershed, recharge area, storage, or infrastructure to keep that supply reliable.
Waste: This is the part people tend to overlook.
Your sewage system doesn’t just need a place to put sewage. It needs soil, treatment capacity, separation from groundwater and drinking-water sources, and enough suitable land for the system to function safely.
In Pennsylvania, for example, wastewater land-treatment systems can require significant separation distances from private drinking-water wells. That means the geometry of the property can matter almost as much as the number of acres.
At the right scale—and with proper treatment—some things we call “waste” become inputs into another system.
So tonight I’m starting at the smallest possible unit:
One human.
How much land does one human actually need to provide food, water, and a safe place to put—or recycle—everything that comes out of them?
How many acres do you need for your own shit?
Then we’ll scale it up.
Because four people don’t necessarily require four times the land. And four people sharing a watershed, a food system, and a waste-treatment system creates an entirely different problem.
Tonight: micro. Next: macro.
MACRO
Tonight’s homework assignment: How much land do we need for all our shit?
AKA: The “Who Will Fend for Themselves?” Experiment
Last night was micro: How much land do I need for just me?
Tonight is macro: How much land do we need for me, my family, and company?
In two different experiments—one in New Zealand and one in Pennsylvania—families have been trying to find the answer.
Interestingly, both case studies arrived at a remarkably similar result: if you can optimize the use of roughly 100 acres, you can support about 20 people, although toward the lower end of what we would consider a modern standard of living.
And that’s when the bigger problem became evident.
As part of our long-term planning, we had to determine who would be allowed to come live with us in a crisis such as climate change.
There were eight of us. We figured our parents would need to be among the first to come. That added six, bringing us to 14. Then we started adding siblings, their partners, and their children. We quickly exceeded 25.
So the real question became:
Who gets invited?
And who is left to fend for themselves?
That sounds like an abstract thought experiment when you have plenty of land, food, water, and energy. It becomes a very different question when those resources have a hard limit. And as climate change accelerates—and the number of grandchildren continues to grow—these questions are no longer really about “future generations.”
They are about our own descendants.
They are the people who may actually have to confront the new realities we are leaving them.
That’s the part of the experiment I find hardest to calculate.
Not how many people the land can sustain.
But who gets to be one of them.
Notes
In New Zealand, Ganantchian Claire said:
Human waste is a very easy “problem “. Composting is super easy, safe, and valuable. Water of course depends where you are. Stream, or roof water are easy gravity fed, groundwater requires energy to bring it up. Food, acreage… as you say, depends entirely on your soil and climate. My opinion is a cow or a couple of goats are the easiest quickest way to get food security as milk covers all your needs. My experience is plants are great, but unreliable as crops can be devastated in a flash by pests or weather events. To avoid starvation, I would never give up my milking cow. One could actually survive with no land at all just walking a cow along the roadsides. A bit extreme, but why not?
In Pennsylvania, USA, I replied:
Nice! Thanks. “Real food” is the hardest thing in my environment as well, especially in the winter. When I say real food, I mean exactly what you said—food security. Eating vegetation is not something I can do for any extended period, and winter makes that particularly difficult.
Though your winters get cooler, I assume they aren’t quite as extreme as Pennsylvania’s, are they?
This becomes particularly relevant when we get to the “macro” experiment.
You also raise another important point with your example of “walking a cow along the roadsides.” In our experiment, we set it up as a game. One of the rules is that you can’t use other people’s land.
That, too, depends on where you live—and on what is considered public property versus private property. Ultimately, I think this is a debate that is likely to intensify as climate migration itself intensifies.
As for waste management, this also appears to be heavily dependent upon location.
In Pennsylvania, the largest long-term problem is waste management, followed by food, then water. But if you don’t manage waste properly, water quickly becomes your biggest problem. Contamination of drinking-water supplies from inadequate or poorly located waste management has been a long-term issue.
Traditionally, you needed at least 10 acres if you could not “perc” your lot.
Collecting rainwater isn’t necessarily a viable solution either. There simply isn’t enough precipitation in many locations across the continental U.S. And in several states, there are legal restrictions on collecting or impeding the flow of water unless you specifically own the water rights.
That’s what makes this experiment so interesting.
The answer isn’t just “How much land do I need?”
It’s where is the land, what can it produce, where does the water come from, and where does the poo go?
How many acres do you have available and how many people do you think you could sustain?
Ganantchian replied:
Interesting conversation. It highlights one of the biggest obstacles to self sufficiency is regulations.
We have 100 acres of land. 25 acres retired to native bush and wetlands, 50 acres very steep of very poor quality soil, 25 acres of which have been planted in poplars. And 25 acres of gently slopping with average quality soil.
I reckon we would comfortably feed 20 people in a localised system ie no fossil fuels or synthetic fertilisers use. Because of the poor inherent quality of our soil, manure from animals and us is the most valuable resource. If composted properly, it is safe to use around fruit and nut trees, which we have planted over 100 over the farm.
Our climate is very mild and with usually good rainfall although we do get drought. Rainwater is vital for drinking as I drunk water from our creek as an experiment and got quite sick Although it’s fine when boiled.
But again, the biggest hurdle is having to pay land rates. Which at the moment the livery horses cover. They do take up 90% of our grazing land… so currently the farm can only sustain 1 or 2 people… All because we are forced to fund Growth in the region, new roads, infrastructure for cars which I loathe, airport extensions which I vowed to never use again…
Hence it is very difficult to prepare for the unfolding multi crisis while the authorities are impeding our progress.
I responded:
Yes, very interesting indeed. Our macro experiment was intended to demonstrate how many people we could sustain on similar acreage. The result was almost identical.
Two families of four acquired 135 acres. About 35 acres were “public rights of way,” and another 20 acres were steep slopes and other unlivable acreage. Some of those 35 acres consisted of three streams, so potable water wasn’t a problem. One of the streams originated from a spring on the property and tested safe for drinking.
We had a cattle and chicken farmer adjoining the property. We exchanged our tillable acreage, about 65 acres, for him to grow feedstock in exchange for him raising a couple of cows and some chickens for us. There were also fish, small game, deer, and other protein sources. That left us about 15 acres for vegetables.
We did not fully develop and complete the land-management plan because it was not economical at the time. However, we did a thorough plan for being able to survive the winters. Solar panels offered the best and cheapest energy source. Small hydroelectric systems installed in the streams could add additional wattage. In addition, a small windmill could pump water up the steep slope to a small reservoir, which could be used as a “battery” for hydropower when the sun wasn’t shining.
Sewage ended up being the limiting factor.
Without sewage, we could sustain about 38 people. With sewage, that number dropped to about 25. The three streams were great for eating and drinking, but they limited where we could build sewage treatment systems without having rainwater runoff contaminate the drinking water and food sources.
The end result was a self-sustaining property of roughly 100 acres that could provide enough food, water, and energy for 20–25 people.
That is when the bigger problem became evident.
As part of our long-term plan, we had to determine who would be allowed to come live with us in a crisis such as climate change. There were eight of us. We thought our parents would need to be the first to be saved. That was an additional six, bringing the total to 14. If all of our siblings, their mates, and kids were included, we quickly exceeded 25.
So that became the bigger issue.
Who would be on the list of people invited versus the list of people to fend for themselves?
As climate change accelerates and the number of grandchildren grows, these questions are no longer about future generations. They are about our own descendants being forced to confront the new realities they will inherit.
She asked:
did you give up?
Yes, I equally feel that I only can provide for close loved ones. It might become different if our local community wakes up. But so far, most of my neighbors think the crisis is a distant worry for the next generation. I’m more than happy to open my gardens to as many people as possible. As long as they are on the same page, and putting in the hard yards.
People seem to think we have time. But the systems you are describing take years to put into place. 50 years ago is when humanity should have gone down that track.
Now… we barely have time to prepare for our small family groups…
Makes me ponder if I’ve done it in the right place as the local population (walking distance) is about 2000 people. 99% of whom rely entirely on being fed by supermarkets and takeaways…
I replied:
No, we didn’t give up. We achieved the goals of the study.
I was the climatologist, economist, and estate planner, as well as the land-management executive. What became obvious was that the physics, science, and logic of a crisis weren’t going to be the real problem.
The security of the infrastructure from outside threats—and the internal trust required to manage the “financial trust fund”—were going to be the larger crisis within the crisis.
One would hope that a crisis would bring us—humanity—together.
Unfortunately, the opposite appears to be true.
Fear and greed are inherent problems that get amplified in a crisis.
That was probably the most important thing we learned from the experiment.
The Amazon is more than a rainforest. It is part of Earth’s climate-regulating system—and one of the places where a regional disruption could become a global problem.
This tipping point season, watch the Amazon closely.
A major Amazon dieback would not remain an Amazon problem.
As forests lose resilience, carbon storage can decline, regional rainfall patterns can shift, and warming can intensify. Those changes could interact with other vulnerable parts of the Earth system—from permafrost thaw and ice-sheet collapse to AMOC slowdown.
That is the danger of tipping cascades:
One system destabilizes → amplifies warming and disruption → increases pressure on another → triggers further change.
The result could be a cascade that moves far beyond the Amazon.
🌳 Amazon dieback → carbon loss & rainfall disruption → additional warming → pressure on other tipping systems → global climate cascade
The critical question isn’t simply “Will the Amazon reach a tipping point?”
It is:
What happens when tipping points begin interacting with one another?
🔬 Tipping Point Season: The Amazon Dieback A closer look at why the Amazon matters—and why what happens there may not stay there.
The 2023–2024 El Niño was the first recorded instance of the Amazon shifting from a carbon sink to a net emitter. This makes Amazon dieback one of the most concerning climate tipping points. Some tipping points, such as coral reef die-off, though deeply concerning, have less of an amplification effect on climate change. The Amazon, however, is far more consequential. As its forests deteriorate, the Amazon can become one of the largest self-amplifying feedback loops in climate collapse.
The 2023–2024 El Niño
Brazil’s Pantanal wetlands are famous for their extraordinary biodiversity. There were 2,387 fires in the Pantanal during the first 13 days of November 2023—an increase of more than 1,000 percent from the entire month of November the previous year, according to satellite monitoring by the Brazilian space research agency INPE.
“The situation is completely out of control. And between the heatwave and the wind, it’s only going to get worse,” said biologist Gustavo Figueiroa, head of the environmental group SOS Pantanal.
What do you know about the Rio Negro as it relates to climate change and carbon sinks?
The Rio Negro gets its name from the color of its water. Its black water is caused by highly acidic, carbon-rich organic material. One scientist who lives on the river has compared its appearance to Coca-Cola. In 2023, the Rio Negro recorded record-low water levels.
Most of the carbon discharged into the water helps carbon eventually sink into the ocean, effectively contributing to a carbon sink. Lack of rain and drought conditions, however, result in more vegetation dying and contribute to a feedback loop: more plants die from reduced rainfall, while there is less rain to wash excess carbon toward the river system and ultimately into the ocean. The result is less carbon being removed from the atmosphere, contributing to additional global warming and further vegetation loss.
From March 16 through 18, 2024, Brazil experienced a severe heatwave, setting new records in Rio de Janeiro, with a reported wet-bulb temperature reaching 62.3 degrees Celsius (144.1 degrees Fahrenheit). Wet-bulb temperature reflects the body’s ability to cool itself through the evaporation of sweat. As heat and humidity increase, sweat evaporates less effectively, making it more difficult for the body to regulate its core temperature. A wet-bulb temperature of 35°C (95°F) at 100% humidity, or approximately 115°F at 50% humidity, represents the upper limit of safety, beyond which the human body cannot effectively regulate its core temperature through sweat evaporation.
On March 23, an atmospheric river event brought heavy rains to Brazil’s Rio de Janeiro state, resulting in at least nine fatalities, primarily in Petrópolis, which bore the brunt of the impact. An astonishing 270 mm (11 inches) of rain fell within a 24-hour period, significantly affecting the region and leading to numerous incidents, including landslides and house collapses.
Contributing Causes
The Amazon is under stress from multiple sources: ground-level ozone and carbon drawdown, deforestation, and climate-circulation breakdown.
A key and increasingly important feature of the observational record is that multiple climate and ecological indicators in the Amazon appear to be shifting into what can be described as “jerk” behavior—dynamics in which not only the state of the system is changing, but the rate of change itself is changing. In mathematical terms, this corresponds to increasing higher-order derivatives of system behavior, where acceleration is no longer stable but itself accelerates over time.
In practical terms, jerk behavior is observed when systems transition from relatively smooth or predictable trajectories into regimes characterized by rapidly compounding variability, abrupt shifts, and feedback amplification. In the Amazon context, this is suggested by signals such as increasing volatility in precipitation extremes, faster transitions between drought and recovery states, and weakening resilience following disturbances such as heat stress or fire events.
The 2026–2027 El Niño Amplifier
The Amazon is the most directly impacted tipping point from the 2026–2027 El Niño.
Amazon Rainforest Dieback — Most Directly Affected
Mechanism: Walker Circulation disruption
Warm ENSO phases shift the atmospheric ascent zone eastward into the Pacific, driving intense and prolonged atmospheric subsidence—dry air—over northern and central South America. This causes severe droughts, heatwaves, and fire outbreaks that exhaust soil moisture and degrade the forest toward a savanna-like state.
A developing super El Niño is compounding severe historical drought and deforestation stress, pushing the Amazon rainforest dangerously close to an irreversible dieback tipping point.
Current Pressures
Delayed Rains: The El Niño event threatens to delay the wet season.
Dry-Season Peak: Scientists expect El Niño to peak between October and December. This timing leaves forest undergrowth tinder-dry when river levels are lowest.
Loss of Resilience: Decades of logging and warming mean large parts of the forest take much longer to recover from seasonal dry spells.
Tipping Point Risks
Savanna Transition: Continuous dry shocks risk converting rich rainforest into open savanna.
Carbon Reversal: Stressed trees release massive amounts of carbon instead of storing it, accelerating global warming.
Unprecedented Threat: The combination of a super El Niño with rising greenhouse-gas concentrations creates an extreme and potentially unprecedented danger for the Amazon basin.
Human and Environmental Toll
Inhabited Areas Hit: Data highlights that more than 38% of human settlements in the Amazon experienced high exposure to recent El Niño droughts, as reported by Agência Brasil.
Megafire Risks: Hotter and drier conditions sharply increase the threat of uncontrollable wildfires that can damage primary forest areas.
Conclusion
The Amazon is not an isolated tipping point. Its potential dieback is dangerous precisely because it can amplify other tipping points across the Earth system.
As the rainforest loses biomass and its capacity to absorb carbon declines, more greenhouse gases remain in the atmosphere. At the same time, drought, heat, and fire can turn portions of the forest from a carbon sink into a carbon source. That additional warming does not stop at the borders of the Amazon. It adds pressure to already-stressed climate systems around the world.
The feedbacks can extend from tropical forests to permafrost. Additional warming accelerates permafrost thaw, releasing carbon dioxide and methane and creating another source of atmospheric warming. That warming further increases pressure on ice sheets, contributing to sea-level rise and potentially accelerating the destabilization of Greenland and West Antarctica.
The same warming also affects the ocean and atmospheric circulation. Changes in temperature, precipitation, and freshwater input can weaken major circulation systems such as the Atlantic Meridional Overturning Circulation (AMOC). A weakening AMOC can, in turn, alter rainfall patterns, ocean heat distribution, and regional climate, adding further stress to other tipping elements.
This is what makes the Amazon particularly important. A tipping point does not have to topple the entire climate system by itself. It can help push other systems closer to their thresholds. Once several tipping elements begin reinforcing one another, the Earth system can move from individual disruptions toward a cascading sequence of self-amplifying changes.
The Amazon therefore represents more than the potential loss of a rainforest. It represents the possibility of activating another major component of a global climate feedback network—one that can intensify warming, weaken resilience elsewhere, and make previously distant tipping points more likely to be crossed.
This tipping point season, watch the Amazon closely. A dieback there would not remain an Amazon problem. It could become an amplifier for tipping points from permafrost thaw to ice-sheet collapse and AMOC slowdown—turning a regional ecological crisis into a global climate cascade.
On September 4, 2026, President Donald Trump escalated his ongoing pressure campaign against the Federal Reserve following a stronger-than-expected August jobs report. The unexpectedly strong labor-market data increased market expectations that the Federal Reserve could raise interest rates as was already expected.
Trump responded with a sweeping threat on Truth Social: if the Federal Reserve does not lower interest rates, he said he would stop trading with countries with which the United States runs a trade deficit. He demanded that the Fed “get smart” and “BE PATRIOTS for a change,” while arguing that the United States should have the lowest interest rate in the world.
As one prominent economist associated with the Wharton School put it, this is insane.
The problem begins with a fundamental misunderstanding of the role of the Federal Reserve.
The Federal Reserve Must Remain Independent
The Federal Reserve’s operational independence exists for a reason. Congress established a framework that gives the Fed significant independence in conducting monetary policy while holding it accountable to its statutory objectives of maximum employment and stable prices.
This independence is not an inconvenience to be overcome by political pressure. It is one of the foundations of monetary credibility.
A central bank that is perceived as responding directly to the political demands of the president risks losing the credibility that allows it to control inflation expectations and maintain confidence in the currency. Federal Reserve officials have repeatedly emphasized that institutional credibility is essential to effective monetary policy.
That matters enormously for the United States because the dollar remains the world’s dominant reserve currency. The Federal Reserve reported in 2026 that the dollar remains the most widely used currency in foreign-exchange transactions and cross-border payments and the leading currency in official reserve holdings. That position is supported not only by the size of the American economy and the depth of U.S. financial markets, but also by confidence in U.S. institutions.
The independence of the Federal Reserve is therefore not merely an institutional technicality. It is part of the infrastructure supporting confidence in the dollar.
The Trade-Deficit Fallacy
The second problem is the premise that a U.S. trade deficit is inherently a loss for America.
It isn’t.
A trade deficit means that the United States imports more goods and services than it exports. But that is only one side of the accounting identity. The other side is the flow of foreign capital into the United States.
The Federal Reserve Bank of Dallas explains that trade deficits are the mirror image of foreign capital inflows. They can reflect strong domestic investment, fiscal expansion, global savings flows, and the unique role of the U.S. dollar as the world’s dominant reserve currency.
In other words, foreigners do not simply “take” something from America when they sell us more goods than they buy from us. The dollars ultimately flow back into American financial assets, businesses, real estate, government securities and other investments.
That capital finances American consumption and investment.
The Congressional Research Service similarly notes that the trade deficit allows Americans to consume more goods than they produce and allows the United States to finance more investment with foreign capital. It can therefore benefit U.S. consumers and borrowers, including the federal government.
The trade deficit is not automatically a sign of economic weakness. In many circumstances, it is a consequence of America’s economic strength, investment opportunities, capital markets and the global demand for dollar-denominated assets.
Trying to eliminate a trade deficit by simply eliminating trade would therefore attack the symptom rather than the underlying economic relationships.
Threatening Higher Inflation to Force Lower Rates
The third problem is perhaps the most fundamental.
If the objective is to reduce borrowing costs, threatening policies that undermine confidence in the Federal Reserve, disrupt international trade and increase inflationary pressure is precisely the wrong direction.
The president’s demand for lower short-term interest rates does not determine long-term borrowing costs. Bond investors ultimately price Treasury securities based on their expectations for inflation, economic growth, fiscal conditions, monetary policy and institutional credibility.
If investors begin to believe that monetary policy is being subordinated to political demands, they can demand greater compensation for holding dollar-denominated debt.
That means higher—not lower—long-term interest rates.
The irony is profound: an attempt to force interest rates lower can produce the very conditions that push market rates higher.
The Market’s Immediate Message
The financial markets reacted to both the jobs report and Trump’s threat, with futures markets increasing the implied probability of a September rate increase while spot-market interest rates rose almost immediately.
The broader message from the bond market is important.
Markets do not simply obey political demands.
They price risk.
And when political pressure raises questions about the future independence of monetary policy, investors can respond by demanding higher yields and a larger risk premium.
That raises borrowing costs throughout the economy—from the federal government to corporations to households.
The Economic Contradiction
The contradiction is difficult to miss. The stated objective is lower interest rates. But forcing the Federal Reserve to cut rates through political pressure could undermine confidence in the institution.
The stated objective is to eliminate trade deficits. But eliminating trade with deficit countries would also eliminate the imports that American consumers and businesses purchase and disrupt the foreign capital flows associated with those trade relationships.
The stated objective is to strengthen the American economy. But deliberately creating uncertainty around monetary policy and international trade risks increasing inflation, raising borrowing costs and reducing investment.
The United States did not become the world’s largest economy by treating every trade deficit as a financial loss. Nor did the dollar become the world’s dominant reserve currency because American monetary policy was subordinated to short-term political demands.
The strength of the American economic system rests on something much larger: deep and liquid capital markets, open international commerce, property rights, the rule of law, institutional credibility and confidence in the stability of the dollar.
Those are assets that can take generations to build. They can be damaged much faster.
The central question is therefore not whether interest rates should be higher or lower at any particular moment.
The question is whether monetary policy will be determined by economic conditions and the Federal Reserve’s statutory mandate—or by political ultimata.
That distinction matters because the price of undermining confidence in America’s economic institutions is ultimately paid not by the Federal Reserve, but by Americans through higher inflation, higher borrowing costs, reduced investment and a less reliable dollar.
We’ve conducted case studies on the use of AI in a wide variety of environments, including everything from the dynamics of nonlinear chaotic systems to songwriting and musical production.
All produced similar results—benefits to the environment, the economy, and society.
For instance, the climate education and graphics used for this post are based on this scientific paper as well as the publicly accessible version.
If I had created them manually, the costs in time, labor, energy, and resources would have been substantial. Using AI, the direct dollar cost to me was effectively zero, the graphics were generated in about a minute, and the estimated natural-resource cost was roughly $0.067 per image.
By comparison, producing similar graphics through traditional methods could easily have cost hundreds of dollars when accounting for labor, software, revisions, and associated natural-resource use. Mathematically, the AI-generated version required approximately 0.005% of those resources—just five thousandths of one percent of the traditional cost. These savings are equivalent to a reduction in environmental impact.
The benefits—in both environmental savings to the planet through reduced physical-resource use and in the ability to produce and distribute education—far outweigh the costs.
Most importantly:
The only effective way to stop the acceleration of climate change is through the reduction of fossil-fuel combustion.
However, the most likely way of reversing the trajectory of climate change is through people using AI to develop previously unthought-of methods and technologies that can fundamentally change how we produce, consume, and manage resources—and potentially remove greenhouse gases from the atmosphere.
Anti-Science and Technology Rhetoric
Unfortunately, the lack of science and technology literacy is at the root of many of society’s problems. Anti-AI opinions are ironically very similar to the anti-science rhetoric used by climate-change deniers.
Climate-change deniers tend to have little, if any, experience as climate scientists. They often show signs of impaired executive function: the brain’s ability to plan, analyze, and think abstractly. This makes processing complex or nuanced information nearly impossible, fostering an aversion to science, mathematics, and logic. Their thinking becomes rigid, emotionally driven, and black-and-white, leaving them highly susceptible to political propaganda, conspiracy theories, and fear-based messaging. Unable to reason critically or tolerate uncertainty, they cling to misinformation and reject rational discourse—no matter how much evidence is presented.
The same holds true for anti-technology opinions expressed in public. The ill-informed individual has likely never used AI in the role of a climate scientist. Scientists train their own highly specialized AI assistants. AI is artificial SUPPLEMENTAL intelligence. This is not how the ordinary individual usually interacts with AI.
In my case, I have spent years developing multiple specially trained “lab assistants” that have learned from scores of our own work. When Sidd and I started, our work had to be done on Ohio State computers and supercomputers that Sidd helped create. Things like “a floating decimal” were, and still are, a significant problem. Problems that needed solving would take months or years to process. The amount of energy spent on computation was enormous compared with today.
Things have changed for the better.
This year, we were able to establish third-derivative behavior across multiple climate indicators—extremely important developments in climate science that confirm that the acceleration rate of climate change is itself accelerating. This work was completed within four months. Historically, I would have been unlikely to complete this work in my lifetime if it were not for AI.
In the meantime, the United States has gone extremist in anti-science and anti-technology ideology, much to the detriment of science and scientists in the U.S. In fact, we are now working on bringing up our own AI computer using Chinese technology. It will be running on DeepSeek. The single computer will do the work of what used to take at least a dozen servers to accomplish, at a fraction of the price. It will not be run in a data center. It will not be costing society anything. In fact, it will be greatly benefiting society and helping to solve the climate crisis.
So, the next time you want to voice your opinion about AI, do your homework first. Start by getting at least a master’s-level education in climate science. Then spend years training your AI assistants. After completion, I would be happy to discuss AI with you.
Although it’s fine when boiled.
