Climate change has been primarily driven by fossil-fuel emissions creating an energy imbalance. More energy is entering the climate system than is leaving. The accumulation of that energy manifests first as rising temperatures and increasingly as extreme weather energy events such as storms and heatwaves.
Most of the increase in the energy imbalance is stored in the oceans. Consequently, global warming has inertia: even after humans stop adding greenhouse gases to the atmosphere, the climate system will continue responding to the energy already accumulated within it.
The Times They Are a-Changing
Nearly all of the climate scenarios developed over the past several decades were based on avoiding sustained warming above the 1.5°C threshold. Once temperatures began exceeding the 1.5°C tripwire on a regular basis, as has happened since 2020, self-reinforcing feedbacks began to be increasingly activated.
There are millions of feedback processes operating throughout the Earth system. Many accelerate the rate of warming. The most observable is the water-vapor feedback and its connection to the water cycle. Warmer air can hold more water vapor, and water vapor is the most abundant and one of the most potent greenhouse gases.
More warming → more water vapor → more warming → more water vapor ↺
This is a positive feedback loop: the initial warming creates conditions that amplify subsequent warming.
Diminishing Low-Level Clouds and Increasing Ozone
There are two feedback systems that are much less understood but potentially far more consequential.
The diminishing of low-level clouds reduces Earth’s albedo—the fraction of incoming solar energy reflected back into space. Less reflection means more energy is retained by the climate system, causing the energy imbalance and its rate of acceleration to become increasingly nonlinear.
At the same time, increasing tropospheric ozone strengthens the greenhouse effect while also affecting the carbon cycle, shortening the timeline over which carbon remains sequestered.
Within each of these systems are multiple interacting feedbacks that can themselves be amplified and reinforced.
This is the critical distinction between individual feedbacks and a nonlinear Earth system: feedbacks do not necessarily operate independently. They can couple together, creating pathways through which warming accelerates other processes that then accelerate warming again.
The Tipping Points
By 2027, two major climate tipping systems showed evidence of approaching or entering potentially irreversible changes: Amazon dieback and the slowdown of the Atlantic Meridional Overturning Circulation (AMOC).
These are not isolated events. They are components of an interconnected climate system in which changes in one part of the Earth system can alter conditions elsewhere, increasing the potential for cascading effects.
The New Reality
Having tripped the 1.5°C tripwire, both the acceleration and inertia of climate change have created a new reality.
The most likely scenario is global warming of approximately 4°C this century.
If humanity does not reach net zero by 2035, approximately 4–7°C of warming by 2150 becomes the most likely scenario.
The fundamental problem is no longer simply how much warming greenhouse-gas emissions cause. It is how the warming already produced is activating feedbacks that can accelerate the rate of further warming—and how the enormous amount of energy already stored in the oceans creates inertia that will persist long after the initial forcing changes.
Climate change is therefore not a linear process moving steadily toward a predetermined endpoint.
It is an accelerating, coupled Earth-system process with both momentum and feedback.
The question is no longer simply how much we warm the planet.
It is how quickly the climate system begins warming itself.
Low Clouds, Ozone, and the Emerging Climate Jerk Surge
The Question We Should Be Asking
A common assumption in climate projections is that if humanity eventually stops adding greenhouse gases to the atmosphere, global temperatures will eventually stabilize. That basic physical expectation remains important. But it leaves out a potentially critical question:
What happens when the climate system itself begins generating additional warming through feedbacks that have been activated by the warming already produced?
This distinction becomes particularly important as global warming approaches and exceeds 1.5°C above the preindustrial baseline.
The issue is no longer simply how much additional carbon dioxide humans will emit. It is also whether the Earth system is beginning to change in ways that reduce its ability to regulate incoming energy, weaken natural carbon sinks, and couple multiple feedback mechanisms together.
Two feedbacks deserve particular attention:
The diminishing cooling influence of low clouds and the resulting decline in planetary reflectivity.
The tropospheric ozone feedback, in which ozone simultaneously contributes to warming and damages vegetation that removes carbon dioxide from the atmosphere.
Together, these mechanisms illustrate why climate change cannot necessarily be understood as a simple linear relationship between greenhouse-gas emissions and temperature.
The emerging evidence instead points toward a more complicated possibility: a climate system in which feedbacks are becoming increasingly coupled—and in which the rate of that coupling may itself be accelerating.
From Warming to Feedback Activation
The traditional climate-change framework can be summarized relatively simply:
Some feedbacks are negative and tend to stabilize the system. Others are positive and amplify the initial disturbance. The critical issue is therefore not merely whether a feedback exists. Positive climate feedbacks have been known for decades. The more important question is whether previously modest feedbacks become stronger, interact with other feedbacks, or cross thresholds as warming increases.
That is where the recent climate record becomes particularly interesting.
A 2022–2026 analysis examined six major climate-system variables: cloud cover, planetary albedo, sea-ice extent, atmospheric water vapor, ocean heat content, and surface temperature. The analysis identified increasing coupling among these variables beginning most notably around 2022.
The three strongest interaction pathways are:
Planetary Albedo × Ocean Heat Content
Cloud Cover × Ocean Heat Content
Planetary Albedo × Cloud Cover
Together, these three pathways account for 39.6% of the displayed surge weight in the analysis. This is important because these relationships describe an energy pathway rather than merely a temperature trend.
Cloud changes can alter planetary reflectivity. Changes in reflectivity alter solar absorption. Greater solar absorption increases energy entering the climate system. Much of that additional energy enters the ocean. Ocean warming then influences atmospheric moisture, clouds, sea ice, and other components of the climate system.
The result is a network rather than a single feedback.
Feedback #1: The Diminishing Low-Cloud Effect
Low clouds are among Earth’s most important regulators of incoming solar energy.
Because low clouds are generally reflective, they send a portion of incoming sunlight back toward space. A reduction in reflective low-cloud cover therefore has the potential to increase the amount of solar energy absorbed by the Earth system.
The Climate Jerk Surge analysis identifies the Cloud Cover × Ocean Heat Content pathway as contributing 13.2% of the displayed surge weight, while Planetary Albedo × Cloud Cover contributes another 12.1%. Planetary Albedo × Ocean Heat Content contributes 14.3%.
The significance is not that clouds have suddenly become a new climate feedback. They have always been part of the climate system. The significance is that a change in cloud behavior can become coupled to changes in planetary albedo and ocean heat content.
That transforms a relatively simple cloud-radiation relationship into a potentially self-reinforcing energy pathway:
Cloud cover ↓ → albedo ↓ → solar absorption ↑ → ocean heat ↑ → atmospheric and cloud response → further changes in cloud cover and albedo.
This is particularly important in the context of reduced marine aerosol emissions. Marine aerosols can influence cloud formation and reflectivity. Reductions in shipping-related sulfur emissions therefore have the potential to remove part of the atmospheric masking effect that previously reflected sunlight or influenced cloud properties.
The Climate Jerk Surge analysis does not require aerosol reductions to be the sole explanation for recent changes. Rather, it identifies the reduction in marine aerosols as a physically testable external perturbation occurring within a climate system already experiencing greenhouse-gas forcing, ocean warming, internal variability, sea-ice loss, and changing cloud behavior.
That distinction matters.
The argument is not:
“Shipping aerosols caused the recent warming.”
The more important question is:
“Did a reduction in an existing cooling influence help expose or amplify a climate system that was already becoming increasingly sensitive?”
That is a question that can be tested against observations.
The Energy Problem
The importance of low clouds becomes clearer when climate change is viewed through energy rather than temperature alone.
The Earth does not warm because a thermometer says it should warm. It warms when the planet retains more energy than it releases to space. A reduction in low-cloud reflectivity can therefore matter even before its effect becomes obvious in surface temperature.
The sequence begins with radiation:
Reflectivity ↓ → solar energy absorbed ↑ → planetary energy imbalance ↑ → ocean heat content ↑.
Because the oceans store enormous quantities of heat, the surface-temperature response does not necessarily occur immediately or proportionally. This creates an important distinction between the climate state and the climate trajectory. A system can be accumulating energy at an accelerating rate even while surface temperature temporarily fluctuates.
That is one reason temperature alone can obscure changes occurring within the climate system.
Feedback #2: The Ozone Climate Multiplier
Tropospheric ozone presents an entirely different kind of feedback. Ozone is commonly discussed as an air-pollution problem or as a greenhouse gas. But its climate significance extends beyond its direct radiative effect.
Tropospheric ozone can damage vegetation. Vegetation, in turn, removes carbon dioxide from the atmosphere through photosynthesis.
This is why ozone can function as a climate multiplier rather than simply another greenhouse gas.
A Nature Geoscience study cited in the ozone analysis estimated that anthropogenic ozone pollution reduced tropical-forest net primary productivity by approximately 17% globally since 2000. That finding is important because tropical forests constitute a major component of the terrestrial carbon sink.
If atmospheric ozone damages that sink, the consequence is not confined to local air quality or forest health.
It can alter the global carbon cycle.
Ozone Creates a Different Kind of Feedback
The low-cloud feedback changes the Earth’s energy budget directly.
The ozone feedback can change both the energy budget and the carbon budget.
That makes the ozone pathway particularly important when considering nonlinear climate behavior.
More ozone → additional plant damage → still less carbon uptake → still more atmospheric CO₂.
The feedback therefore has the potential to operate simultaneously through atmospheric chemistry and the biosphere.
The effect is compounded when ozone interacts with other climate stresses.
Heat, drought, fire, insects, disease, and hydrological changes can all affect vegetation. Ozone does not have to be the sole cause of forest decline to become climatically important.
In fact, interaction may be the more important issue. A forest already stressed by warming and drought may be less capable of absorbing an additional ozone burden. Likewise, vegetation damaged by ozone may be less capable of recovering from heat, drought, or fire.
Put them together and the problem becomes more complicated:
Lower cloud reflectivity can increase the amount of energy entering the climate system.
Ozone can reduce the biosphere’s ability to remove one of the greenhouse gases already accumulating in the atmosphere.
One mechanism increases the energy entering the system.
The other can reduce the system’s ability to remove a major forcing agent.
Neither mechanism needs to “run away” independently for the combined effect to matter.
They only need to become increasingly coupled with other components of the Earth system.
From Feedbacks to Coupling
The question is not simply:
“Are climate feedbacks operating?”
They obviously are.
The more consequential question is:
“Are multiple feedbacks becoming increasingly interconnected, and is that interconnection itself accelerating?”
Six climate variables generate 15 pairwise coupling pathways. These are not interpreted as 15 independent feedback mechanisms. Instead, they represent different observable relationships within a connected climate system.
The third derivative is important because it asks a different question from ordinary warming measurements.
Temperature tells us how warm the system is.
The first derivative tells us how rapidly temperature is changing.
The second derivative tells us whether the rate of warming is changing.
A third derivative—the “jerk”—asks whether the acceleration itself is changing.
Applied to feedback coupling, the same logic becomes:
How quickly are feedbacks interacting?
How quickly is that interaction accelerating?
And is the acceleration of that interaction itself increasing?
Why 1.5°C Matters
The significance of 1.5°C is therefore not that a magical switch flips at precisely that temperature.
Rather, crossing approximately 1.5°C places the Earth system increasingly far from the climate conditions under which many modern observations and historical relationships developed.
As warming progresses, the probability of activating additional feedbacks increases.
Ice declines.
Water vapor increases.
Cloud behavior changes.
Ocean heat accumulates.
Vegetation experiences increasing stress.
Atmospheric chemistry changes.
Carbon sinks can weaken.
The important question becomes whether these processes remain largely independent or increasingly interact. If they remain independent, the climate response may remain comparatively manageable. If they become strongly coupled, one feedback can change the conditions under which another feedback operates.
That is the mechanism by which a collection of individually understood processes can produce a nonlinear system response.
What This Means for Temperature Stabilization
This brings us back to the original question:
If humans stopped emitting greenhouse gases, how long would it take for temperatures to stop rising?
The conventional answer depends heavily on the assumption that the climate system’s feedback structure remains sufficiently stable. But that assumption deserves increasing scrutiny. Stopping anthropogenic emissions would remove the primary source of additional human forcing. It would not instantly reverse ocean warming, restore lost ice, rebuild reflective cloud regimes, repair damaged vegetation, or restore weakened carbon sinks. Nor would it necessarily turn off feedbacks that have already been activated.
This does not mean that continued warming after net-zero emissions is inevitable, nor does it establish a specific future temperature. It means the stabilization problem is more complicated than simply setting future human emissions to zero. If climate feedbacks are already amplifying the rate of warming, emissions must reach zero faster, and even greater reductions will be required to slow the accelerating rate of climate change. In other words, the longer we wait, the more difficult it becomes to reverse the acceleration already underway.
The relevant equation is not merely:
Human emissions → atmospheric CO₂ → temperature.
It is closer to:
Human forcing → warming → feedback activation → feedback coupling → changing energy and carbon flows → additional warming.
If the coupling terms themselves are accelerating, then projections based on a relatively stationary feedback structure may underestimate the possibility of nonlinear behavior.
The Emerging Climate Jerk Surge
The importance of the 2022–2026 observations is therefore not simply that several climate indicators have moved in an unfavorable direction. The more interesting signal is that multiple indicators appear to be moving together.
The strongest relationships identified involves precisely the variables expected to participate in an energy-amplification pathway:
These pathways can ultimately converge on the same outcome: additional energy retained within the climate system. That is why the distinction between individual feedbacks and feedback coupling is so important. A single feedback can be studied in isolation; a nonlinear Earth system cannot.
Two of the most consequential impacts already emerging are the increasing stress and potential dieback of the Amazon rainforest and the weakening of the Atlantic Meridional Overturning Circulation (AMOC). Both illustrate how individual climate stresses can propagate through interconnected Earth-system processes, potentially amplifying changes far beyond their initial point of origin.
A Different Climate Question
The conventional climate question has been:
How much will temperatures rise for a given amount of greenhouse-gas emissions?
An increasingly important question may be:
How is the climate system itself changing as warming increases?
That requires monitoring more than temperature.
It requires watching:
planetary energy imbalance
ocean heat content
cloud cover and cloud radiative effects
planetary albedo
atmospheric water vapor
sea ice
vegetation productivity
carbon-sink strength
tropospheric ozone
atmospheric chemistry
and, critically, the changing relationships among these variables.
Conclusion: The Feedback Problem Is Becoming a Coupling Problem
Low clouds and tropospheric ozone illustrate two very different ways in which natural systems can amplify anthropogenic climate forcing.
Diminishing low-cloud reflectivity can allow more solar energy to enter the climate system.
Tropospheric ozone can both warm the atmosphere directly and weaken biological carbon sequestration by damaging vegetation.
The first primarily changes the energy budget.
The second can alter both the energy budget and the carbon budget.
Neither mechanism needs to operate alone.
Both exist within a larger network of interacting climate processes.
The important development is the increasing coupling among these processes rather than the activation of any single new feedback. The strongest observed relationships involve cloud cover, planetary albedo, and ocean heat content, forming a tightly connected radiative-energy pathway.
This changes the central question.
The question is no longer simply whether stopping greenhouse-gas emissions would eventually stabilize global temperature.
The question is whether the climate system we are trying to stabilize is still the same system that existed when many of those stabilization expectations were developed.
If positive feedbacks are becoming more strongly coupled—and if the coupling itself is accelerating—then the timescale and magnitude of future warming may depend increasingly on processes that are no longer controlled directly by human emissions.
The warning is not simply that the planet is warming.
It is that the machinery producing and amplifying that warming is itself changing.
And if that machinery is accelerating, temperature may be the last variable to reveal how rapidly the underlying system has changed.
Q: What’s your take on not having a single hurricane this season?
Great question! I’ve written several papers on this topic, and I think what we’re seeing is particularly interesting.
As of September 23, the Atlantic has produced six named storms but still has produced zero hurricanes—an exceptionally delayed first hurricane. NOAA’s current summary shows Atlantic ACE about 92% below the 1991–2020 average at this point in the season.
What alarms me isn’t simply the lack of hurricanes. It’s the apparent coupling of climate patterns that historically operated more independently. I first warned about this Pacific El Niño–Atlantic Niña coupling back in May. Now, as we progress this far into the season, the observations are providing an unusually clear real-world example of how teleconnections can link distant parts of the climate system.
The simultaneous occurrence of an extreme Pacific El Niño and an anomalous Atlantic Niña represents a significant disruption of the historical baseline. NOAA reports that the El Niño is strengthening, with eastern equatorial Pacific sea-surface temperatures already more than 3°C above average.
An Atlantic Niña can suppress Atlantic hurricane development through increased atmospheric stability and wind shear. So there is a relatively straightforward physical explanation for the quiet Atlantic. But I think the deeper question is why these large-scale ocean–atmosphere patterns are coupling so strongly in the first place.
That’s where my climate-acceleration research comes in. I see this as evidence worth watching for increasingly interconnected feedbacks and teleconnections—changes in ocean circulation, atmospheric circulation, energy redistribution, and the hydrologic and carbon cycles that can influence one another across ocean basins.
In other words, the absence of hurricanes isn’t evidence that the climate system is becoming less energetic. It is the opposite: climate energy is being redistributed in ways that produce very different outcomes in different parts of the planet.
The hurricane season is therefore only one piece of a much larger climate-system puzzle.

How Is the Climate Energy Hitting You? SoCal Coastal Armoring Sea Level vs. Private Property Rights = Managed Retreat
🌊 Climate energy is hitting the coast.
When waves encounter a hard structure instead of dissipating their energy across a gradually sloping beach, some of that energy can be reflected back toward the ocean.
That can increase scour at the base of the structure and accelerate the loss of sand immediately in front of—and adjacent to—the armored shoreline.
A difficult feedback loop can develop:
Loss of sand → greater wave energy → erosion → emergency armoring → altered wave & sediment dynamics → further beach loss
The result is a fundamental conflict:
Protect individual properties — or preserve the beach as a public resource.
🌊 Climate Change Changes the Equation
This isn’t simply a dispute over seawalls.
It’s a preview of a much larger problem.
As sea levels rise, coastal storms and extreme-wave events interact with a progressively higher baseline ocean. More energy can reach vulnerable shorelines, while the loss of beaches and dunes removes natural buffers that once absorbed part of that energy.
The physical equation is changing.
🏖️ Managed Retreat
Managed retreat may ultimately become the long-term strategy for some coastal properties.
The fundamental physical reality is simple:
You can build a wall against the ocean. You cannot build a wall against a changing climate.
The Beach Road conflict is therefore about much more than a temporary rock wall.
It is about what happens when accelerating climate change collides with private property rights, public resources, and the physical limits of coastal engineering.
The ocean doesn’t recognize property lines.

Sea Level vs. Private Property Rights
The Battle Over Coastal Armoring
The situation along Beach Road in Dana Point, California, illustrates an increasingly difficult collision between rising sea levels, intensifying coastal hazards, private property rights, and the public’s right to California’s beaches.
Powerful southern swells associated with Hurricane Marie, combined with an anticipated record El Niño season, have stripped away much of the protective sand buffer along the shoreline. Several multimillion-dollar beachfront homes have been severely damaged, with some collapsing directly into the Pacific Ocean.
At least 10 beachfront homes have been red-tagged, meaning they have been declared unsafe to inhabit, while another seven have been yellow-tagged, restricting their use. Facing the loss of their homes and investments, residents have taken matters into their own hands.
The Battle Over Coastal Armoring
To protect what remains of their properties, a group of homeowners pooled their own money, contributing between $50,000 and $120,000 per household, to construct a massive temporary rock barrier, or riprap wall, extending across 17 vulnerable properties.
The California Coastal Commission granted temporary emergency permits for the barrier. But the decision has opened a much larger legal, environmental, and property-rights debate.
The Homeowners’ Position
The homeowners argue that they have a constitutional right to protect their homes and private property from destruction.
Many of the affected properties were built in the 1950s, long before today’s coastal development regulations were established. Residents point out that they pay substantial property taxes and argue that government agencies have failed to provide promised or expected beach-sand replenishment and other protective measures.
From their perspective, they are being asked to absorb enormous private losses while being restricted from taking reasonable measures to protect property they legally own.
The Environmental and Regulatory Position
The Coastal Commission and coastal scientists emphasize that hard coastal armoring—including seawalls, rock revetments, and similar structures—can alter natural coastal processes and contribute to beach erosion.
When waves encounter a hard structure rather than dissipating their energy across a gradually sloping beach, wave energy can be reflected back toward the ocean. This can increase scour at the base of the structure and accelerate the loss of sand immediately in front of and adjacent to the armored shoreline.
The result can become a difficult feedback loop:
Loss of sand → greater wave energy at the shoreline → erosion → emergency armoring → altered wave and sediment dynamics → further beach loss.
That creates a fundamental conflict between protecting individual properties and preserving the beach as a public resource.
The 120-Day Problem
The emergency permits for the rock barrier are temporary, lasting only 120 days.
If the homeowners cannot obtain permanent authorization—which is highly restricted for certain coastal properties, particularly homes constructed after 1977—they could ultimately be required to remove the expensive barrier.
That creates an extraordinary dilemma: homeowners may spend hundreds of thousands of dollars attempting to save their properties, only to face the possibility that the protective structure must be dismantled just as the most damaging winter storms arrive.
State authorities are instead encouraging communities to consider longer-term adaptation strategies, including cobblestone berms, elevating structures, and, where necessary, managed retreat.
Climate Change Changes the Equation
This conflict is not simply a dispute over seawalls.
It is a preview of a much larger problem.
As sea levels rise and coastal storms and extreme-wave events interact with a progressively higher baseline ocean, the amount of energy reaching vulnerable shorelines can increase. The loss of beaches and dunes removes natural buffers that once absorbed part of that energy.
That means yesterday’s shoreline protections may not be adequate for tomorrow’s climate.
The fundamental problem is that private property rights operate within a physical system that does not recognize property boundaries. The ocean does not distinguish between private property, public beaches, or political jurisdictions.
As climate change accelerates, coastal communities will increasingly have to confront the difficult question of where—and how—private property can realistically be protected.
Managed Retreat
Managed retreat may ultimately become the only sustainable long-term strategy for coastal properties.
A fundamental physical reality:
You can build a wall against the ocean, but you cannot build a wall against a changing climate.
The Beach Road conflict is therefore about much more than a temporary rock wall.
It is about what happens when accelerating climate change collides with private property rights, public resources, and the physical limits of coastal engineering.
Climate change can be understood in one deceptively simple equation:
ENERGY IN − ENERGY OUT = ENERGY ACCUMULATING
Earth has been accumulating excess energy for decades. Most of that excess heat—roughly 90%—is going into the oceans.
What matters now is not just that Earth is out of balance, but that the imbalance itself is changing.
The recent acceleration in Earth’s energy imbalance raises an important question:
Are we moving from a relatively steady warming system toward a climate system increasingly driven by interacting feedbacks?
Ice loss. Clouds. Water vapor. Ocean heat. Carbon sinks.
When these systems interact, the climate response can become increasingly nonlinear.
ACCELERATING ENERGY IMBALANCE = ACCELERATING CLIMATE CHANGE
The simplest way to understand global warming may be to stop looking only at the thermometer—and start looking at the energy.
Read the full paper:
The Energy Imbalance (EEI)
A simple way to understand climate change and global warming is through Earth’s energy balance—or, more precisely, the growing lack of balance known as Earth’s Energy Imbalance (EEI).
Earth’s climate is governed by a fundamental exchange: energy arrives primarily from the Sun, while Earth returns energy to space as reflected sunlight and outgoing infrared radiation. When incoming and outgoing energy are equal over the long term, the planet is approximately in energy balance. When more energy enters the Earth system than leaves it, the difference is stored within the climate system, producing warming.
The Basic Energy Equation
There are two fundamental pathways involved in Earth’s energy budget:
Energy enters and leaves. Sunlight brings energy into the Earth system, while reflected sunlight and outgoing infrared radiation carry energy back into space.
Energy enters and is temporarily stored. Some of the incoming energy remains within the Earth system as heat. It warms the oceans, land, and atmosphere and melts snow and ice. Today, roughly 90% of the excess energy associated with the imbalance is stored in the ocean.
The important point is that energy cannot simply disappear. If less energy leaves the Earth system than enters it, the difference accumulates somewhere within the system.
From Balance to Imbalance
For thousands of years before large-scale industrialization, Earth’s climate system fluctuated around a long-term energy balance. Beginning with the Industrial Revolution, however, human activities increasingly altered that balance.
The primary driver is the buildup of greenhouse gases such as carbon dioxide and methane. These gases reduce the rate at which Earth can emit infrared energy to space. As a result, more energy remains in the Earth system.
This does not mean that every year must be warmer than the preceding year. Natural variability—including El Niño and La Niña—can temporarily redistribute energy between the ocean and atmosphere and produce substantial year-to-year fluctuations. But over longer periods, a persistent positive EEI means that the Earth system continues accumulating energy.
The Imbalance Is Increasing
The remarkable development is not simply that Earth has a positive energy imbalance. The rate of energy accumulation has increased.
NASA and NOAA observations combining CERES satellite measurements with ocean observations found that Earth’s energy imbalance approximately doubled between the first decade of the 21st century and the 2005–2019 period. A 2024 observational assessment likewise found that CERES measured an increase from approximately 0.5 ± 0.2 W/m² during 2000–2009 to 1.0 ± 0.2 W/m² during 2010–2019.
The increase was not simply a matter of more greenhouse gases trapping infrared radiation. The CERES analysis found that absorbed solar radiation increased by about 0.9 W/m², while outgoing longwave radiation increased by about 0.4 W/m², partially offsetting that additional absorbed solar energy.
That distinction is important.
The Earth system can become more energetically unbalanced through changes in both:
how much solar energy is absorbed, and
how much infrared energy escapes to space.
Why the Post-2020 Period Matters
The years since 2020 have attracted particular scientific attention because several factors have combined to produce unusually large changes in Earth’s radiation budget.
One important contributor is the sharp reduction in sulfur emissions from international shipping following the IMO 2020 regulations. Sulfate aerosols reflect sunlight and can brighten clouds, producing a cooling influence. Their reduction therefore allows more solar radiation to reach and remain within the Earth system.
A 2024 modeling study estimated a global effective radiative forcing from IMO 2020 of approximately +0.14 W/m², primarily through aerosol-cloud interactions. The study estimated that the regulation could contribute about 0.046°C of additional global warming during 2020–2029, while emphasizing that other factors are required to explain the exceptional warmth of 2023.
This is significant, but it should not be interpreted as meaning that shipping regulations alone caused the recent surge in Earth’s energy imbalance.
The climate system is responding simultaneously to greenhouse-gas forcing, aerosol changes, clouds, water vapor, surface albedo, ocean circulation, volcanic activity, and internal variability.
A Rapidly Changing Radiation Budget
CERES observations provide direct measurements of changes in Earth’s radiation budget from space. The data show substantial changes in both absorbed solar radiation and outgoing longwave radiation.
The year 2023 was particularly unusual. Global annual mean absorbed solar radiation was about 1.75 W/m² above the CERES reference climatology, while outgoing longwave radiation was about 0.85 W/m² above the reference. The resulting annual mean net radiation anomaly was approximately +0.90 W/m².
NASA has also reported that 2023 produced exceptionally large anomalies in absorbed solar radiation, with values exceeding the 90% confidence interval for much of March through September. The exceptionally large absorbed-solar and outgoing-longwave anomalies continued into early 2024.
These observations demonstrate something important:
Earth’s energy budget is not static. It is changing.
And the changes involve multiple interacting components of the climate system.
Energy Imbalance and Climate Feedbacks
This is where the concept of climate feedback becomes important.
An initial warming can trigger changes that alter the amount of energy entering or leaving the Earth system. Some of those changes amplify the original warming.
Examples include:
Water vapor: Warmer air can hold more water vapor, and water vapor is itself a greenhouse gas.
Ice and snow: Melting reduces Earth’s reflectivity, allowing more sunlight to be absorbed.
Clouds: Changes in cloud amount, altitude, composition, and properties can alter both reflected sunlight and outgoing infrared radiation.
Ocean warming: The ocean absorbs most of the excess energy, affecting circulation, evaporation, sea level, and atmospheric processes.
Carbon-cycle feedbacks: Warming and changing environmental conditions can alter the ability of terrestrial and oceanic systems to absorb carbon.
These feedbacks do not create energy from nothing. Rather, they change the pathways through which energy moves through the Earth system.
That distinction is crucial.
A feedback can cause the Earth to absorb more solar energy or retain more infrared energy, increasing the rate at which the existing energy imbalance grows.
The Energy Accumulation Is Enormous
The units used to measure EEI—watts per square meter—can make the imbalance sound deceptively small.
For example, 1.0 W/m² means that, averaged across the entire surface of Earth, approximately one additional joule of energy is accumulating every second for every square meter.
Across the entire planet, even a 1.0 W/m² imbalance corresponds to roughly 510 terawatts of continuous power.
At an imbalance of 1.45 W/m², the corresponding rate would be roughly 740 terawatts.
That is an extraordinary amount of energy.
The comparison can be expressed another way. Using the approximate energy yield of the Hiroshima bomb, an EEI of 1.45 W/m² corresponds to an energy accumulation rate on the order of 11 Hiroshima-scale explosions every second.
The important point is not the metaphor itself. It is the scale of the energy involved.
The Earth Is Not Just Getting Warmer
Temperature is only one visible consequence of the energy imbalance.
The accumulated energy is distributed throughout the Earth system. It:
heats the oceans,
warms the land,
warms the atmosphere,
melts glaciers and ice sheets,
reduces sea ice,
expands seawater,
increases evaporation,
intensifies the hydrological cycle,
and contributes to changes throughout the climate system.
NASA’s CERES program estimates that about 93% of the current excess energy is stored in the ocean, illustrating why ocean heat content is such an important measure of Earth’s changing energy budget.
This is why looking only at surface temperature can obscure part of the story.
The climate system is an energy system.
Surface temperature is one measurement of that system—not the system itself.
The EEI Timeline
Historical Period / Era
Approximate EEI Average (W/m²)
Primary Radiative Drivers & Climate Context
1890–1910 (Early Industrialization)
~0.0 to +0.05
The climate remains in near-equilibrium. Early fossil fuel emissions are largely offset by natural variability and background volcanic activity.
1910–1950 (Mid-Century Rise)
+0.05 to +0.15
EEI begins a slight upward crawl. A steady expansion of global manufacturing and coal combustion begins trapping marginal longwave heat.
1950–1970 (The Aerosol Masking Era)
+0.15 to +0.25
The “Great Acceleration” of industry begins. However, heavy sulfur dioxide pollution creates a reflective aerosol blanket, blocking sunlight and masking up to half of greenhouse warming.
1970–1990 (Emerging Imbalance)
+0.30 to +0.50
Clean air regulations reduce sulfur pollution while greenhouse gases continue to climb. The planet begins absorbing noticeably more solar radiation.
1990–2005 (Systemic Multi-Decade Warming)
+0.50 to +0.65
Satellite programs launch. Except for a brief drop following the 1991 Mount Pinatubo volcanic eruption, the EEI remains locked in a consistently positive, warming state.
2005–2019 (The First Acceleration)
+0.70 to +0.90
The long-term EEI average effectively doubles compared to prior decades. Ocean heat content spikes dramatically as the oceans absorb roughly 90% of this excess energy.
2020–2023 (The Post-2020 Surge)
+1.00 to +1.30
Slashed marine shipping pollution (IMO 2020 regulations) rapidly clears atmospheric haze over the oceans, forcing a massive, sudden spike in absorbed solar energy.
2024–Present (Nonlinear Feedback Phase)
+1.40 to +1.48+
EEI hits unprecedented, record-breaking territory. Strong climate feedbacks—such as collapsing Antarctic sea ice and thinning cloud decks—darken the planet, causing it to absorb immense amounts of solar radiation.
The observational record therefore supports a clear long-term conclusion: Earth’s energy imbalance has increased substantially over recent decades.
The precise attribution of the most recent changes remains an active area of research.
The Bigger Picture
The simplest way to understand global warming is not to begin with a thermometer.
Begin with energy.
Earth receives energy from the Sun. Earth emits energy back into space. Greenhouse gases, clouds, aerosols, ice, water vapor, and other components of the climate system influence how much energy enters, how much leaves, and how quickly the system responds.
When the equation is balanced, Earth’s average climate can remain relatively stable.
When the equation is persistently unbalanced, energy accumulates.
And when the rate of that accumulation changes, the climate system changes with it.
Global warming is therefore not merely a temperature problem. It is an energy-accounting problem.
The central question is simple:
How much energy is entering the Earth system, how much is leaving, and how rapidly is the difference changing?
That difference is Earth’s Energy Imbalance.
And it is one of the most fundamental measurements of a changing climate.
Indonesia: Still Burning — When Wildfire Becomes a Climate Feedback
Indonesia’s wildfire carbon dioxide emissions surged to the highest level in the world in early September 2026, driven by an intense El Niño season and extreme drought.
As reported earlier this month, Indonesia is experiencing a dangerous convergence of climate stress: extreme drought, human land-use change, and increasingly intense wildfires across Sumatra and Borneo.
According to the EU’s Copernicus Atmosphere Monitoring Service, as reported through Fire Emissions Watch, Indonesian fires released approximately 19.7 million metric tons of CO₂ between September 1 and September 7, 2026.
That represented more than one-third of global wildfire CO₂ emissions during that period and surpassed Russia.
The significance goes beyond the immediate emissions. Indonesia contains some of the world’s largest tropical peatlands—vast stores of carbon accumulated over thousands of years. When these peatlands dry out and burn, they can release carbon that has been locked away for centuries or millennia.
Regional Haze and Health Impacts
The consequences are not confined to the fire zones.
Smoke haze has spread across neighboring countries, including Singapore, Malaysia, and the Philippines, producing hazardous air-quality conditions. The resulting disruption has included school closures, remote learning affecting more than a million students, and widespread air-quality warnings.
What begins as a regional wildfire can therefore become a regional atmospheric event—with consequences for human health, transportation, education, agriculture, and ecosystems.
Orangutans Under Threat
Critically endangered orangutans are also facing an escalating survival crisis.
Intense wildfires are destroying and fragmenting habitat across Borneo and Sumatra. Extreme drought makes forests and peatlands more vulnerable to ignition, while the combination of drought, land-use change, and El Niño conditions can transform individual fires into large-scale ecological disasters.
For orangutans, the loss is not simply the burning of individual trees. It is the destruction and fragmentation of an already limited habitat.
When Wildfire Becomes a Climate Feedback
The Indonesian fires illustrate a dangerous climate feedback loop: warming and climate variability can create conditions that produce more wildfire, while the resulting fires release additional greenhouse gases and destroy carbon-absorbing ecosystems.
In other words:
Warming → drought → wildfire → CO₂ release + carbon-sink loss → more warming
Indonesia’s tropical peatlands make this feedback particularly important.
1. The Peatland Carbon Bomb
The process:
Peatlands consist of thick, waterlogged layers of partially decomposed plant material. Because decomposition is slowed under waterlogged conditions, enormous quantities of carbon can accumulate over long periods.
During severe drought, such as that associated with strong El Niño conditions, water tables can fall and peat can dry out.
The feedback:
Once dry, peat can ignite and continue smoldering underground. Unlike an ordinary surface forest fire, a peat fire can persist beneath the surface and release enormous quantities of stored carbon.
The critical point is that peat fires can release not only carbon from recently grown vegetation but also carbon accumulated over much longer periods.
2. Destruction of the Rainforest Carbon Sink
The process:
Healthy tropical forests function as major carbon sinks. Through photosynthesis, trees and other vegetation remove CO₂ from the atmosphere and store carbon in biomass and soils.
The feedback:
Wildfire can kill trees, degrade soils, and fragment the forest canopy. The loss of living vegetation reduces the ecosystem’s capacity to remove atmospheric CO₂.
At the same time, dead and damaged vegetation decomposes or burns, returning additional carbon to the atmosphere.
A forest that once removed carbon from the atmosphere can therefore become a source of greenhouse-gas emissions following severe disturbance.
This is a critical distinction: wildfire does not merely add emissions. It can simultaneously remove part of the natural system that would otherwise absorb those emissions.
3. Regional Weather and Surface-Albedo Changes
Wildfires can also modify the physical environment.
Dense smoke and aerosol plumes can spread across enormous areas, reducing incoming sunlight at the surface while altering atmospheric heating. Meanwhile, burned landscapes have different surface characteristics from intact forests, including changes in surface reflectivity, vegetation, soil moisture, and evaporation.
These changes can disrupt local and regional energy and water cycles.
The resulting effects are complex and can vary with atmospheric conditions, but prolonged smoke and vegetation loss can alter evaporation, convection, rainfall patterns, and the persistence of dry conditions.
When drought delays the return of heavy rainfall, peat fires can continue burning underground for extended periods.
The Climate Feedback Loop
The Indonesian situation can be summarized as a sequence:
Step
Action
Impact
1. Trigger
El Niño + climate warming
Increased heat and drought stress
2. Amplification
Peatlands and forests dry out
Landscapes become increasingly fire-prone
3. Event
Peatlands and forests burn
Large quantities of stored carbon are released
4. Carbon-sink loss
Forests are damaged or destroyed
Less CO₂ is removed from the atmosphere
5. Atmospheric response
CO₂ and other greenhouse gases increase
Additional radiative forcing
6. Feedback
Increased warming and ecosystem stress
Greater risk of future drought and wildfire
The Bigger Picture
The Indonesian fires demonstrate why climate change cannot be understood solely as a gradual increase in average temperature.
Climate energy moves through interconnected Earth systems.
A period of extreme heat and drought can trigger wildfire. Wildfire can release stored carbon. The same wildfire can destroy vegetation that would otherwise absorb atmospheric CO₂. Smoke and land-surface changes can alter regional energy and water cycles. The resulting environmental changes can increase the vulnerability of the system to the next extreme event.
That is a feedback.
And when multiple feedbacks begin operating simultaneously, the climate system can become increasingly difficult to treat as a simple linear progression.
The cost of transporting crude oil by the world’s largest oil tankers has reached extraordinary levels.
On the benchmark TD3C route — a 270,000-metric-ton Very Large Crude Carrier (VLCC) traveling from the Middle East Gulf to China — daily time-charter-equivalent (TCE) earnings have surged from roughly $16,000/day in 2020 to more than $1.2 million/day in September 2026.
That is not simply a large increase. It represents an extraordinary transformation in the economics of moving oil by sea.
From $16,000 to $1.2 Million a Day
Period
Approx. TD3C Daily Rate/TCE
What Was Driving the Market
2020
~$16,000/day
Pandemic-era demand collapse and abundant tanker capacity
2025
~$35,000/day average*
Tightening tanker fundamentals, geopolitical rerouting and limited fleet growth
September 2026
$1,212,503/day
Middle East conflict, disruption around the Strait of Hormuz, rerouting and severe tanker scarcity
*McQuilling reported a TD3C average earning of approximately $35,136/day for the first eight months of 2025, rather than $160,000/day.
The 2020 figure is also consistent with contemporary tanker-market estimates. McQuilling projected the TD3C round-trip voyage at approximately $16,200/day for 2020.
Then came 2026.
The $1.2 Million-a-Day Shock
In September 2026, the TD3C benchmark moved into territory rarely seen in modern tanker shipping.
The Baltic Exchange reported that the TD3C rate rose to Worldscale 1,140, corresponding to a round-trip TCE of approximately $1,212,503 per day for a standard Baltic VLCC.
Earlier in September, the same benchmark had already exceeded $1 million/day, with the Baltic assessment reaching approximately $1.099 million/day on September 15.
The surge reflects an extraordinary combination of factors:
disruption to Middle Eastern oil-export routes;
sharply reduced traffic through the Strait of Hormuz;
attacks and security risks affecting regional shipping;
longer and more complicated voyages;
ships being tied up in shuttle and ship-to-ship operations;
and a limited number of immediately available VLCCs.
Reuters reported on September 21 that only 17 commodity vessels transited the Strait of Hormuz over the weekend, compared with 37 the previous week and a pre-conflict average of about 125 vessels per day.
Why Shipping Costs Matter
Oil does not simply move from the wellhead to the refinery.
It has to be transported.
When the cost of transporting a cargo of crude suddenly multiplies, the consequences extend through the entire energy system.
At today’s extreme tanker rates, transportation itself can represent a substantial portion of the delivered cost of crude. The Wall Street Journal reported that VLCC charter costs had exceeded $1 million/day, equivalent to roughly $26 per barrel on the affected voyages.
That means the disruption is not merely a problem for shipowners and oil traders.
Higher transportation costs can therefore add pressure to gasoline, diesel, jet fuel and other petroleum products even when the underlying price of crude oil is moving differently.
An Extraordinary Comparison
The scale of the change is easier to see this way:
2020: ~$16,000/day ↓ 2025: ~$35,000/day average ↓ September 2026:$1,212,503/day
From the approximate 2020 level to the September 2026 TD3C assessment, the daily TCE increased by roughly 75×.
That is an extraordinary change in the economics of moving a single cargo of oil.
And it demonstrates something important about modern energy systems:
When a critical transportation chokepoint is disrupted, the cost of moving energy can become a crisis of its own.
A market under extreme stress
The current rate should not be interpreted as a normal annual shipping cost. It is a spot-market benchmark during an exceptional geopolitical disruption. Rates can move dramatically in either direction as vessel availability, security conditions, oil flows and trade routes change.
But the magnitude of the September 2026 spike is unmistakable.
The cost of moving oil by VLCC has gone from tens of thousands of dollars per day to more than $1.2 million per day.
That is a remarkable indicator of just how much stress has entered the global oil-transportation system.
Plug-and-play solar is becoming available around the world—and it could make solar power dramatically simpler and more accessible.
Plug-and-play solar is part of the emerging clean energy economy. Unlike conventional rooftop solar, these small systems can be installed with minimal equipment and, where permitted, connected directly to an existing electrical outlet. That makes solar potentially accessible to renters, apartment dwellers, condominium owners, and homeowners who cannot install a conventional rooftop system.
Cheaper and Healthier
Plug-and-play solar can reduce electricity costs because sunlight is free and the system produces electricity without ongoing fuel purchases. It also generates electricity without the combustion-related air pollutants produced by fossil-fuel power generation.
Instead of buying fuel from a utility to generate electricity somewhere else, a plug-in solar system can capture sunlight right from a balcony, patio, yard, or other suitable location and produce electricity at the point of use.
Great Britain has taken a major step toward making plug-in solar widely accessible. Beginning August 27, 2026, new rules established a legal framework for plug-in solar panels and other plug-in microgenerators.
Under the new framework, qualifying certified systems can connect to standard 13-amp domestic sockets, subject to safety requirements and output limits. Plug-in solar kits can produce up to 800 watts, and users must notify the local electricity network operator. The UK government says the systems could save households up to £110 per year and provide as much as 20% of average household electricity use.
Ofgem has also approved changes to the distribution code intended to facilitate plug-in solar while maintaining requirements for network safety, supply quality, and system operability.
The United States Is Moving State by State
The situation in the United States is less straightforward. There is currently no single nationwide legal framework for plug-in solar. Instead, states are beginning to establish their own rules.
As of September 2026, nine states have enacted legislation specifically addressing plug-in or balcony solar: Utah, Colorado, Maryland, Maine, Vermont, Connecticut, New Hampshire, Virginia, and New Jersey.
Meanwhile, additional states are considering plug-in-solar legislation. California and New York, among others, have active legislative efforts, illustrating how quickly the regulatory landscape is changing.
Plug-and-play solar is therefore more than another solar product. It represents a shift toward small, distributed, consumer-installed energy generation—putting a small power plant within reach of people who may never own a house with a conventional solar roof.
The sun is already there. Plug-and-play solar makes it easier to use.
☀️ THE CLEAN ENERGY ECONOMY
Harmony Hare says:
🔌 PLUG-AND-PLAY SOLAR IS CHEAPER AND HEALTHIER
Solar power doesn’t have to mean a massive rooftop installation.
Plug-and-play solar is changing the equation.
A small solar system can plug directly into an existing electrical outlet—turning a balcony, patio, yard, or other sunny space into a source of clean electricity.
☀️ FREE FUEL The sun provides the energy. No gasoline. No coal. No natural gas. No ongoing fuel purchases.
💰 LOWER ENERGY COSTS Generate some of your own electricity instead of buying all of it from the utility.
🌱 CLEANER AIR Solar electricity generates power without the combustion emissions associated with fossil-fuel generation.
🏠 MORE ACCESSIBLE Plug-and-play systems can potentially bring solar to renters, apartment dwellers, condo owners, and homeowners who cannot install conventional rooftop solar.
This is the Clean Energy Economy in action:
Small systems. Simple installation. Free sunlight. Less fuel. Less pollution. More distributed energy.
The future of clean energy doesn’t have to be complicated.
I’m generally against rooftop solar, particularly in the U.S. Much of the residential market is based on leased systems, which can be detrimental to the homeowner, especially when the home is eventually sold.
In general, I also recommend putting a new roof on before installing solar. Otherwise, replacing the roof later can mean additional costs and complications with the solar system. And the payback period can be longer than the length of time many homeowners actually own their homes.
There’s another fundamental problem: in both the U.S. and UK, it can be difficult to install enough rooftop solar to meet a home’s actual electricity demand, particularly during periods of peak heating or cooling. The times when energy demand is highest are not necessarily the times when a rooftop array produces the most electricity. That can make the system less useful—and potentially a liability when selling the property.
As a consultant, I almost always recommend ground-mounted solar when the property allows it. It avoids many of the structural, roofing, maintenance, and resale issues associated with rooftop systems while providing much greater flexibility in system placement and orientation.
In my view, there are very few disadvantages to properly designed ground-mounted solar, while many of the supposed advantages of rooftop solar are really advantages of having solar—not advantages of putting the panels on the roof.
Plug-And-Play Solar
What I’m totally in favor of, however, is plug-and-play solar. Plug-in solar, balcony solar, or other plug-and-play systems can connect directly to an existing electrical outlet, making solar dramatically simpler and less expensive to install. Great Britain has now established a legal framework for these systems: updated regulations taking effect August 27, 2026, created a legal category for plug-in microgenerators and allow certified systems to connect to standard 13-amp domestic sockets, subject to safety requirements, output limits generally up to 800 watts, and notification to the local electricity network operator. Unfortunately, the situation remains much less straightforward in the U.S., where regulation is largely state-by-state. At present, plug-in solar is legal in only nine states: Utah, Colorado, Maryland, Maine, Vermont, Connecticut, New Hampshire, Virginia, and New Jersey.
Known Ozone: The Climate Change Agent That Damages the Carbon Sink
By Daniel Brouse
Tropospheric ozone is a powerful greenhouse gas.
Ozone (O₃) is one of the most important individual greenhouse gases contributing to global warming, ranking behind carbon dioxide (CO₂) and methane (CH₄) in terms of its direct contribution to human-caused warming.
But ozone does something most greenhouse gases don’t: it also damages the plants that remove CO₂ from the atmosphere.
Ozone is a powerful phytotoxin—it harms plants. That creates an important climate feedback: the same ozone pollution that contributes directly to warming can damage vegetation, reduce photosynthesis, weaken carbon sequestration, and leave more CO₂ in the atmosphere.
Ozone is therefore both an atmospheric forcing agent and an ecological forcing agent.
More ozone → more warming
and
More ozone → weaker carbon sinks → more CO₂ → more warming
That second pathway is the part of the ozone story that is often overlooked.
Ozone Damages Tropical Forests
A study published in Nature Geoscience, “Reduced productivity and carbon drawdown of tropical forests from ground-level ozone exposure,” found substantial reductions in tropical forest productivity associated with anthropogenic ground-level ozone exposure.
The study estimated that anthropogenic ozone pollution reduced tropical forest net primary productivity by approximately 17% globally since 2000.
That is a major climate consequence. Tropical forests are among Earth’s most important biological carbon sinks. When ozone reduces their productivity, their capacity to remove carbon from the atmosphere is reduced. Ozone has also been identified as one of the stressors contributing to the risk of Amazon forest dieback, alongside warming, drought, fire, and other interacting pressures.
The message is simple:
Ozone doesn’t just warm the planet. It can damage one of the planet’s major systems for removing CO₂.
Pennsylvania Forests Show the Warning Signs
Long-term observations of mature forests in Pennsylvania provide evidence of serious changes in forest health that warrant examination in the context of ozone exposure, climate stress, and carbon sequestration.
Since approximately 2003, observations across multiple monitoring intervals have reported substantial changes in some old-growth forest systems, including:
Approximately 40% foliage loss
Significant canopy thinning
Approximately 33% reductions in canopy height
Increased premature mortality
These changes cannot automatically be attributed to ozone alone. Forest decline is produced by interacting stresses, including ozone, heat, drought, hydrological disruption, insects, disease, and extreme weather. But that does not make ozone less important. It makes the interaction more important.
When multiple environmental stresses strike the same forest, ozone can become another force reducing the ability of vegetation to grow, survive, and store carbon.
The Ozone Multiplier
Ozone is therefore more than another greenhouse gas.
It can operate simultaneously through two pathways:
Atmospheric pathway
Ozone → greenhouse warming → more climate stress
Biological pathway
Ozone → plant damage → less photosynthesis → weaker carbon sinks → more atmospheric CO₂ → more warming
Put the two pathways together and ozone becomes a powerful climate multiplier.
The atmosphere warms the biosphere.
The biosphere normally removes CO₂ from the atmosphere.
Ozone interferes with that exchange.
Known Ozone
Ozone’s direct greenhouse effect is well established. Its ability to damage vegetation is also well established. The climate significance comes from putting those two facts together.
Ozone warms the planet.
Ozone damages plants.
Damaged plants remove less carbon.
Less carbon removal leaves more CO₂ in the atmosphere.
More CO₂ means more warming.
That makes ozone more than an air-pollution problem.
It makes ozone part of the climate feedback system itself.
And when the direct warming effect and the carbon-sink effect are considered together, ozone sits atop of the climate-change pyramid.
Known ozone. Known warming. Known plant damage. Known powerful feedback.
