Sweden: Heatwaves, Hydroclimatic Whiplash, Forest Decline, Coastal Erosion and the Northward Spread of Disease
Sweden is warming rapidly, and the impacts of that warming are increasingly moving from long-term projections into everyday disruptions. A changing climate is reshaping Sweden’s risks across multiple interconnected systems—from heat and water to forests, coastlines, agriculture, and human health.
The Swedish Meteorological and Hydrological Institute (SMHI) and climate-impact assessments identify several major vulnerabilities that are becoming increasingly important.
1. Disruptive Heatwaves and the “Unprepared Housing” Crisis
More Frequent Extreme Heat: Sweden is experiencing increasingly frequent and intense heat events, including prolonged periods above 30°C (86°F) and, in extreme cases, 35°C (95°F) or higher. Although Sweden’s climate remains relatively cool compared with many parts of the world, its population and infrastructure are not designed for sustained extreme heat.
The Insulation Paradox: Much of Sweden’s housing stock was designed primarily to retain heat during long, cold winters. That efficiency can become a liability during prolonged summer heat, particularly in buildings without mechanical cooling or adequate passive ventilation.
Dangerous Warm Nights: Rising nighttime temperatures are especially important. When homes and buildings cannot cool overnight, people receive little physiological relief from daytime heat. Older adults, people with chronic conditions, outdoor workers, and other vulnerable populations face increased risks of heat exhaustion, cardiovascular stress, and premature death.
What was once considered an unusual summer inconvenience is increasingly becoming a public-health and infrastructure challenge.
2. Hydroclimatic Instability: Flash Floods vs. Drought
Climate change is intensifying Sweden’s water-cycle extremes, creating a dangerous contradiction: more intense rainfall can occur alongside longer periods of water scarcity.
Extreme Rainfall and Cloudbursts: A warmer atmosphere can hold more water vapor, increasing the potential for intense precipitation. Short-duration summer cloudbursts can overwhelm urban drainage systems, flooding streets, buildings, transportation networks, wastewater systems, and critical infrastructure.
Agricultural and Soil Drought: At the same time, prolonged periods without sufficient rainfall can rapidly dry soils. Higher temperatures increase evaporation and plant water demand, making drought conditions more severe even when annual precipitation does not decline dramatically.
Groundwater Stress: Extended dry periods can also reduce groundwater recharge and threaten local water supplies. Agriculture, forests, ecosystems, and municipalities can therefore experience water stress even during a year that produces damaging floods.
The result is increasingly hydroclimatic whiplash—rapid transitions between excessive water and insufficient water.
3. Forest Stress, Degradation and Wildfires
Sweden’s forests are both an economic resource and a major carbon store, making their increasing climate stress particularly consequential.
Heat and Drought Stress: Repeated heatwaves and prolonged drought reduce soil moisture and place trees under physiological stress. Weakened trees become more vulnerable to disease, insects, wind damage, and other disturbances.
Norway Spruce Vulnerability: Norway spruce, an important commercial species particularly in southern Sweden, is vulnerable to drought and heat stress. Water-stressed trees can become more susceptible to secondary pest outbreaks, accelerating forest decline.
A Longer Wildfire Window: Climate change does not necessarily create the ignition source for a wildfire, but it can make the landscape substantially more receptive to fire. Hotter temperatures, low humidity, dry vegetation, and prolonged drought can extend the period during which fires spread rapidly.
Large wildfires can destroy ecosystems and communities while releasing carbon stored in vegetation and soils—creating another feedback between climate change, forest health, and atmospheric carbon.
4. Coastal Erosion and Rising Sea Levels
Sweden’s coastline faces increasing pressure from rising sea levels, changing storm patterns, and coastal erosion.
Rising Baseline Water Levels: Global sea-level rise raises the starting point from which storm surges occur. Even where local land uplift moderates the rate of relative sea-level rise, some coastal areas remain increasingly exposed to flooding and erosion.
Storm-Surge Amplification: Strong autumn and winter storms can temporarily push water levels far above the average sea level. As the baseline rises, the same storm can produce greater coastal flooding and erosion.
Southern and Western Coastlines: Low-lying areas, particularly along parts of Skåne and Sweden’s western coast, face increasing long-term risks to beaches, wetlands, roads, buildings, and other infrastructure.
Cities and population centers including Malmö and Gothenburg face a particularly important challenge: protecting densely developed coastal areas while adapting to a coastline that is increasingly dynamic.
5. Vector-Borne Diseases Moving North
Climate change is also altering Sweden’s biological geography.
Expanding Tick Habitat: Warmer temperatures and milder winters can improve survival conditions for ticks and allow them to establish or remain active farther north and for longer portions of the year.
Tick-Borne Disease Risk: Diseases such as Lyme disease and tick-borne encephalitis (TBE) are therefore becoming increasingly important public-health concerns as environmental conditions change.
The northward expansion of vectors illustrates an important feature of climate change: the impacts are not limited to temperature. Warming can reorganize ecosystems and alter where infectious diseases can persist and spread.
Sweden’s Climate Risk Is Becoming a Systems Problem
These hazards do not occur independently.
Heat increases evaporation and worsens drought. Drought weakens forests and increases wildfire risk. Wildfires release stored carbon and damage ecosystems. Extreme rainfall can then produce flash floods after dry periods. Rising seas increase coastal exposure, while warmer conditions alter the distribution of disease-carrying organisms.
The emerging pattern is therefore not simply “Sweden is getting warmer.”
It is a more complicated transformation of the country’s water cycle, forests, coastlines, infrastructure, ecosystems, and public-health systems.
Climate energy is increasingly expressing itself through compound and cascading extremes—where one disruption increases the vulnerability to the next.
For Sweden, climate change is becoming less about a distant future and more about how quickly its existing systems can adapt to a rapidly changing physical environment.
Philadelphia to Washington: Severe Storms, an Expanding “Tornado Alley,” Straight-Line Winds, and the Urban Heat Island
The Philadelphia-to-Washington corridor has experienced an extraordinary number of severe thunderstorm and tornado warnings this year. So far, 353 warnings have been issued across the region, putting the I-95 corridor from Washington, D.C., through Baltimore and Philadelphia at the center of an unusually active severe-weather season.
This concentration of warnings is not the result of a single cause. It reflects the interaction of a warming climate with the atmospheric conditions that generate severe thunderstorms: more available moisture, greater atmospheric instability, strong wind shear, warmer land and ocean surfaces, and increasingly favorable conditions for rapidly developing storms.
An Expanding “Tornado Alley”
The traditional image of “Tornado Alley” centers on the Great Plains. But severe-weather climatology is not static. Over recent decades, the eastern United States has experienced a growing share of tornado and severe-convective activity, with the Mid-Atlantic increasingly exposed to damaging storms.
The Washington-to-Philadelphia corridor is particularly vulnerable because of its geography. Warm, moisture-rich air from the Atlantic Ocean and the Gulf Stream can surge northward and collide with cooler, drier air and frontal boundaries moving eastward across the Appalachians.
When those ingredients overlap with sufficient wind shear and atmospheric instability, the result can be rapidly developing thunderstorms capable of producing tornadoes, damaging winds, large hail, and torrential rainfall.
A Warmer Atmosphere Means More Atmospheric Fuel
One of the most important climate connections is atmospheric moisture.
For every 1°C of warming, the atmosphere can hold approximately 7% more water vapor. A warmer atmosphere does not automatically produce severe weather, but when moisture is available and the other ingredients for convection are present, that additional moisture provides more energy and water for intense storms.
Along the heavily urbanized Northeast corridor, this can produce extremely high rainfall rates. Downpours capable of dropping several inches of rain in a short period can overwhelm drainage systems and produce flash flooding with little warning.
The same moisture-rich environment can also contribute to stronger thunderstorms by increasing the amount of latent heat released as water vapor condenses within developing storm clouds.
Microbursts and Damaging Straight-Line Winds
Not every destructive wind event is a tornado.
Many severe thunderstorm warnings along the I-95 corridor involve straight-line winds, downbursts, and microbursts. These winds can reach 60–70 mph or more and can cause damage comparable to that produced by weaker tornadoes.
A microburst occurs when a powerful column of descending air reaches the surface and spreads outward rapidly. The resulting winds can knock down trees and power lines, damage structures, overturn vehicles, and create dangerous conditions for aviation.
The distinction matters because the damage may look similar to tornado damage even when no tornado occurred.
The Urban Heat Island Adds Another Layer
Philadelphia, Baltimore, and Washington, D.C., are enormous concentrations of concrete, asphalt, buildings, vehicles, and other heat-absorbing surfaces.
These urban areas create a heat-island effect, in which temperatures remain higher than in surrounding rural areas, particularly after sunset. During the day, intense solar heating can further warm the surface and the air immediately above it.
When this heat interacts with an already warm, humid atmosphere, it can increase atmospheric instability. Boundaries created by differences between urban and rural heating can also help influence where thunderstorms develop or intensify.
That does not mean the urban heat island “causes” every severe storm. Rather, it is another component of an increasingly complex environment in which multiple sources of atmospheric energy can interact.
Climate Energy Meets Weather
The critical point is that climate change does not replace ordinary weather dynamics. It changes the background conditions in which those dynamics operate.
A warming Atlantic provides additional heat and moisture. A warmer atmosphere increases moisture capacity. Warmer urban surfaces add localized heat. Strong frontal boundaries and wind shear provide the structure needed for severe convection.
When these ingredients come together, the result can be a rapidly escalating sequence:
The result is not simply “more storms.” It is an atmosphere increasingly capable of producing higher-impact extremes when the right ingredients align.
For the Philadelphia-to-Washington corridor, the extraordinary number of severe-weather warnings this year is another reminder that climate energy is not an abstract measurement on a graph. It is expressed through the atmosphere above our cities—and increasingly through the storms moving across them.
353 warnings is not just a number. It is a measure of how often the atmosphere has been reaching the threshold for potentially dangerous weather.
Nepal–Tibet: Glacier Loss, Permafrost Collapse, Glacial Lake Outburst Floods, Flash Floods, Mudslides and Avalanches
Hundreds of people are missing—including hundreds of foreign tourists and pilgrims—after a deadly flash flood struck the Nepal–Tibet border. CCTV footage from Tibet shows a wall of water and mud sweeping into buildings at a border crossing, while images from Nepal show people scrambling to escape as floodwaters surge through the area.
Nepal is a major destination for mountaineers, trekkers, and Hindu and Buddhist pilgrims. Thousands of people travel through the Himalaya each year to visit sacred sites.
August is also a busy season for travelers heading toward Mount Kailash, located in Tibet’s Ngari Prefecture, which is administered by China. The journey from Kathmandu can take roughly 10 days, and thousands of pilgrims cross the Nepal–Tibet border to reach these sacred destinations.
Nepalese tourism officials say hundreds of pilgrims are missing, including more than 100 Indians. The Gyirong–Rasuwagadhi border crossing, a major route between Nepal and Tibet, was struck by a powerful surge of mud and water.
But this disaster is about more than one extreme event.
The Nepal–Tibet Himalayan region sits at the intersection of several climate-sensitive systems: glaciers, snowpack, permafrost, steep mountain slopes, monsoon rainfall, rivers, and glacial lakes. As the region warms, these systems can become increasingly unstable—and their failures can compound one another.
A Mountain System Under Increasing Stress
The Himalaya is warming rapidly, with high-elevation regions experiencing particularly significant changes. Rising temperatures are accelerating glacier loss, altering snow and ice dynamics, thawing permafrost, and increasing the potential for cascading hazards.
The important point is that these hazards do not operate independently.
A warming atmosphere can destabilize a glacier.
A collapsing glacier can trigger an avalanche.
An avalanche can strike a glacial lake.
The resulting displacement wave can breach a natural dam.
The flood can then pick up enormous quantities of rock, soil, and debris as it races downstream.
By the time it reaches a populated valley, what began as warming in the high mountains can become a wall of water, mud, ice, and rock.
Accelerating Avalanches and Permafrost Collapse
Glaciers across the Hindu Kush Himalaya are losing mass rapidly. Retreating glaciers expose unstable terrain while warming temperatures alter the physical structure of ice and frozen ground.
Hanging glaciers can become increasingly unstable. Warmer conditions can promote fracturing and destabilization of ice perched above steep slopes. When large sections collapse, they can generate enormous ice-and-rock avalanches.
Permafrost is another critical component. At high elevations, permanently frozen ground acts like a kind of natural cement holding fractured rock and mountain slopes together. As that frozen ground thaws, the strength of the mountain system can decline.
The result can be slope failures, rockfalls, landslides, and massive collapses into river valleys.
From Glacier Loss to Flash Floods
One of the most dangerous consequences is the increasing potential for glacial lake outburst floods, or GLOFs.
As glaciers retreat, they can leave behind lakes contained by unstable piles of glacial debris called moraines. These natural dams are considerably less predictable than engineered structures.
An avalanche, landslide, or large rockfall entering one of these lakes can displace enormous volumes of water. The resulting wave can overtop or breach the moraine, releasing a sudden flood downstream.
And the flood can become much larger as it moves.
A surge entering a narrow Himalayan valley can pick up boulders, trees, soil, ice, and other debris. What emerges downstream may no longer resemble a conventional flood. It becomes a rapidly moving mixture of water and sediment capable of destroying bridges, roads, buildings, power facilities, and entire communities.
Monsoon Extremes and Mudslides
The other half of the equation is rainfall.
Climate change is altering the hydrological cycle. A warmer atmosphere can hold more water vapor, increasing the potential for extremely intense precipitation when that moisture is released.
The danger is not simply more rain.
It is greater volatility.
Longer dry periods can be followed by exceptionally intense rainfall. When torrential precipitation falls onto already unstable slopes, landslides and mudflows can occur with little warning.
Mountain terrain makes the problem even more severe.
Steep slopes, fractured rock, thawing permafrost, retreating glaciers, and saturated soils create conditions in which enormous quantities of sediment can suddenly move downhill.
Critical transportation corridors are particularly vulnerable. Highways, bridges, tunnels, and hydropower facilities frequently occupy narrow valleys—the same pathways followed by floodwaters and debris flows.
The August 2026 Border Disaster
The current disaster along the Nepal–Tibet border illustrates how these hazards can interact.
Reports indicate that an ice-and-rock avalanche blocked the Lhende River, a tributary of the Bhotekoshi River. A localized magnitude-4.4 earthquake may also have contributed to destabilizing the terrain.
The resulting blockage and subsequent flooding generated a massive surge of water and debris, reportedly producing a mudflow roughly 33 feet high.
The flood destroyed or severely damaged border infrastructure, including the strategic Friendship Bridge, and caused major casualties around Tibet’s Gyirong port.
At least 22 people have been confirmed dead, while hundreds of international tourists and pilgrims remain missing according to reports.
The disaster also damaged Nepal’s electricity infrastructure, temporarily taking a substantial portion of the country’s hydropower capacity offline.
This is an important reminder that climate-driven disasters do not only kill people directly.
They can also disable the infrastructure societies depend upon for transportation, electricity, communications, food distribution, tourism, and emergency response.
The Cascade Is the Story
The most important climate signal here is not any single flood, avalanche, landslide, or rainfall event.
It is the coupling of hazards.
Warming
↓
Glacier loss + snow and ice instability
↓
Permafrost thaw
↓
Unstable mountain slopes
↓
Avalanches and landslides
↓
Glacial lake disruption and river blockages
↓
Extreme rainfall
↓
Flash floods + debris flows + mudslides
↓
Destroyed infrastructure
↓
Disrupted electricity, transportation and tourism
↓
Human casualties
This is what makes the Himalaya particularly vulnerable to a changing climate.
The mountains are not experiencing isolated changes. They are experiencing changes in a tightly connected system.
When one component moves, it can destabilize another.
And when several components move simultaneously, the result can be a cascade.
Climate Energy Is Moving Through the System
The Himalaya is a powerful example of what climate change actually means on the ground.
Climate change does not simply mean that the average temperature rises by a few degrees.
It means that additional energy enters the climate system and changes how water, ice, rock, soil, and atmospheric moisture interact.
In the high Himalaya, that additional energy is destabilizing parts of the cryosphere while increasing the atmosphere’s capacity to transport moisture.
The result is a dangerous combination:
More unstable ice + more unstable ground + more atmospheric moisture + extreme precipitation = greater potential for cascading disasters.
For people living in Himalayan valleys—and for the millions who depend upon these mountains for water, transportation, energy, agriculture, tourism, and cultural traditions—the consequences are becoming increasingly difficult to separate from everyday life.
The question is no longer simply whether climate change is occurring.
The question is:
How is the energy already entering the climate system moving through the landscape—and where will the next cascade begin?
Death Valley: When the Desert’s Extremes Become More Extreme
Death Valley has always been one of the hottest, driest, and most inhospitable places on Earth. But human-caused climate change is pushing those natural extremes into increasingly dangerous territory. The valley’s unique topography—essentially a vast natural basin that traps heat—can amplify warming, while changing atmospheric conditions are producing longer heat waves, warmer nights, more intense rainfall, and increasing ecological stress.
Death Valley is not simply getting hotter. Its entire pattern of extremes is becoming more extreme.
Death Valley Lives Up to Its Name
The danger is not theoretical. Extreme heat, difficult terrain, vehicle accidents, and sudden medical emergencies make Death Valley one of the most hazardous environments in the National Park System.
August 2026: Extreme Heat and Fatalities
Pierre Michel Formosa — August 17, 2026: The 68-year-old French tourist died after his rental vehicle became stuck in mud on remote West Side Road. In temperatures reaching 116°F (46.6°C), Formosa and his companion attempted to walk across the open salt flats toward Badwater Road for help. Formosa collapsed and died roughly 1.3 miles into the trek. Park officials subsequently reminded visitors to remain with disabled vehicles, particularly where shade and visibility can improve the chances of rescue.
Unresponsive visitor south of Badwater — August 2026: Emergency responders located a deceased woman after receiving reports of an unresponsive visitor during a stretch of consecutive days in which temperatures exceeded 120°F.
Extreme heat can also contribute to mechanical failures and indirect deaths. When temperatures become extreme, vehicles, tires, batteries, cooling systems, electronics, and other mechanical components are pushed beyond the conditions for which they were designed. A breakdown in a remote or dangerously hot environment can quickly become a life-threatening event.
Death Valley provides a stark example. Some deaths there have been associated with vehicle failures that left people stranded in extreme heat. In such cases, the vehicle failure itself may not be the direct cause of death, but it can become a critical link in the chain of events that ultimately leads to fatal heat exposure.
This is an important dimension of climate risk that is easy to overlook. Extreme heat doesn’t only affect the human body directly; it can destabilize the systems people depend on to survive. A failed vehicle can mean the loss of transportation, air conditioning, communications, or access to water and medical assistance. As extreme temperatures become more frequent and intense, these indirect pathways to injury and death become increasingly important to consider.
1. Scorching Heat Waves Are Lasting Longer
Death Valley has always experienced extraordinary heat. Climate change, however, is increasing the baseline temperature on which these extremes occur, making prolonged heat events more dangerous.
Persistent high-pressure systems and heat domes can trap hot air over the region. Instead of experiencing a brief spike in temperature followed by meaningful relief, the valley can endure successive days of extraordinary heat.
Death Valley has repeatedly approached or exceeded 125°F (51.7°C) during major heat events, including extraordinarily long runs of extreme temperatures. The park’s record-setting summers increasingly cluster in the recent decades, illustrating how the climate baseline has shifted.
The significance is not simply another record high.
A hotter baseline makes extreme heat easier to reach—and harder to escape.
2. The Nights Are Getting Hotter
One of the most consequential changes associated with global warming is the rise in nighttime temperatures.
Historically, desert nights provided at least some relief from daytime heat. But as temperatures rise, that recovery period is becoming less reliable. During prolonged summer heat events, nighttime temperatures can remain extraordinarily high, sometimes failing to fall below 80°F and, during the most extreme events, remaining near or above 100°F (37.8°C).
That matters because the human body needs opportunities to shed accumulated heat.
When nights remain unusually warm, people, animals, vegetation, and infrastructure begin the next day without fully recovering from the previous one. The result is a form of cumulative heat stress:
Hot day → insufficient nighttime cooling → hotter starting point → greater heat stress → even greater vulnerability.
In Death Valley, where daytime temperatures can already exceed 120°F, the loss of nighttime relief is particularly dangerous.
3. “Once-in-a-Thousand-Year” Flash Floods
Death Valley presents a striking climate paradox: one of the driest places in North America can also experience devastating flash floods.
Warmer air can hold more atmospheric moisture. When that moisture is released in intense thunderstorms, rainfall can overwhelm the desert’s ability to absorb and channel the water.
The result can be catastrophic.
In August 2022, a historic storm dropped roughly 75% of Death Valley’s average annual rainfall in only about three hours. Floodwaters trapped hundreds of visitors, damaged or destroyed vehicles, and severely damaged park infrastructure.
The event demonstrated an important feature of a warming climate:
Extreme drought and extreme rainfall are not opposites. They can occur in the same place—and increasingly interact with one another.
Parched, hardened or poorly infiltrating desert surfaces can transform intense rainfall into rapidly moving floodwater. Canyons and steep terrain then concentrate that water into powerful torrents.
A place can therefore become simultaneously hotter, drier, and more vulnerable to extreme flooding.
4. Seasons Are Shifting
The climate signal is not confined to the middle of summer.
Extreme heat can arrive earlier in the year, rapidly drying winter and early-spring vegetation and shortening the period when conditions are relatively hospitable.
That matters because Death Valley’s plants and animals have evolved within a narrow set of environmental conditions. They are adapted to heat and drought—but adaptation has limits when environmental conditions change faster than biological systems can respond.
The park’s famous desert ecosystems are therefore being exposed to multiple pressures at once:
Earlier and more persistent heat
Greater evaporative demand
Reduced soil moisture
Longer periods of drought
More intense rainfall events
Greater wildfire and vegetation stress
Reduced opportunities for seasonal recovery
Species that depend on specific temperature and moisture conditions can be especially vulnerable. Joshua trees, for example, face increasing difficulty establishing new seedlings in portions of the Southwest as hotter and drier conditions alter the environments needed for successful reproduction.
Bird populations and other wildlife are also affected by changes in water availability, food resources, vegetation, and extreme heat.
Death Valley Is Becoming a Climate Stress Test
Death Valley has always been an extreme environment. That is precisely why it provides such a powerful illustration of climate change.
Climate change does not need to transform Death Valley into something completely different. It can amplify the characteristics that already define it.
The heat becomes hotter.
The heat lasts longer.
The nights provide less relief.
Rain falls less predictably and can arrive with greater intensity.
The seasons shift.
Ecological recovery becomes more difficult.
The result is not simply a warmer Death Valley. It is a more volatile and increasingly stressful climate system.
Death Valley has always lived up to its name.
The emerging question is whether the ecosystems—and the people who venture into them—can continue to live with the increasingly extreme conditions that made the valley famous in the first place.
Extreme Extremes: Walpeup and Hopetoun, Australia; Floridia, Italy; Miami, Florida; Joubertina, South Africa; Bridgeport, Connecticut; Philadelphia, Pennsylvania
Extreme Extremes: Record Heat, Rain, Snow, and Flooding Around the World
Several towns and cities across the globe have broken or approached major historical extreme-weather records so far in 2026. From record-setting heat in Australia and Florida to extraordinary rainfall in South Africa and Connecticut—and a historic blizzard in Philadelphia—the pattern is increasingly difficult to characterize as ordinary weather variability.
🌡️ Extreme Heat & Wildfires
Walpeup and Hopetoun, Australia: In late January 2026, these two towns in Victoria baked under a staggering 48.9°C (120°F) during a catastrophic wildfire season, setting potential all-time temperature records for the region.
Floridia, Italy: This Sicilian town has continued to experience intense summer heat, drawing international attention as one of Europe’s extreme heat zones.
Miami, Florida: In August 2026, Miami officially tied its all-time hottest day on record at 100°F, another indication of how extreme heat is becoming an increasingly familiar feature of the climate.
🌧️ Torrential Rain & Flooding
Joubertina, South Africa: Between May 5 and May 8, 2026, an intense low-pressure system dumped a historic 301.2 mm (11.86 inches) of rain on the town in just three days, triggering devastating flash floods.
Bridgeport, Connecticut: In August 2026, Bridgeport recorded its wettest meteorological summer on record, following a relentless series of heavy downpours.
❄️ Severe Snow & Blizzards
Philadelphia, Pennsylvania: In late February 2026, a massive historic blizzard blanketed the region with 13.7 inches of snow, accompanied by intense, gale-force winds. It was the city’s most severe single-day snowfall event in a decade.
The Bigger Picture
These events span three continents and multiple climate extremes: record heat, wildfire conditions, torrential rainfall, flash flooding, extreme wetness, and major winter storms.
Climate change does not mean that every extreme-weather event is caused by climate change. It does mean that a warmer atmosphere and warmer oceans can alter the conditions in which these events develop—loading the climate system with additional energy and moisture and increasing the potential for extremes.
The question is no longer simply whether extreme weather is occurring.
The question is how much more extreme the extremes are becoming—and how quickly.
Indiana and New York: When 1-in-1,000-Year Rain Becomes a Real-World Risk
The Changing Meaning of “Rare”
A “500-year flood” does not mean a flood that occurs only once every 500 years. It describes an event with an estimated 0.2% chance of occurring in any given year, based on historical and statistical assumptions.
The problem is that those assumptions can become outdated as climate conditions change.
Rainfall and flooding once considered extraordinarily rare are occurring more frequently in many regions. Events that infrastructure and communities were designed to withstand only once in a century—or once in several centuries—are increasingly being challenged by rainfall extremes outside the historical range.
The summer of 2026 provides another striking example.
Indiana: Record Rainfall and a Record White River
In August 2026, central and east-central Indiana experienced a prolonged period of severe weather and extreme rainfall. A powerful derecho moved through the region on August 11, producing destructive winds, hail, and tornadoes. The storm was followed by repeated rounds of heavy thunderstorms that moved over already saturated ground.
The National Weather Service reported more than 11 inches of rain in some parts of central Indiana. New Castle recorded 11.24 inches at one observing site, while a location near New Lisbon recorded 11.50 inches over two days.
The result was catastrophic flooding.
The White River reached record levels at multiple locations. At Anderson, the river crested at 24.93 feet on August 14, breaking the previous record of 23.60 feet set during the Great Flood of 1913. At Noblesville, the river reached 24.60 feet on August 15, also breaking the 1913 record of 23.80 feet.
Roads were washed out, homes and businesses were flooded, and numerous water rescues were required. Indiana Governor Mike Braun declared a statewide disaster emergency and mobilized the Indiana National Guard.
The event was not simply a single downpour. A derecho was followed by repeated thunderstorms and persistent atmospheric moisture, allowing rainfall to accumulate over the same watersheds for several days. The National Weather Service described the resulting flooding in portions of central Indiana as catastrophic.

The significance is not simply that a rainfall record was broken. The larger concern is the interaction between extreme rainfall, saturated soils, repeated storms, and river response.
Once the ground is saturated, additional rainfall increasingly becomes runoff. That runoff rapidly enters streams and rivers, turning an extreme rainfall event into an extreme flood.
New York: Another 1-in-1,000-Year Rainfall Event
Indiana was not alone.
From July 28–30, eastern New York experienced an extraordinary heavy-rain event. The National Weather Service reported widespread rainfall totals of 6 to 12 inches, with localized amounts exceeding 11 inches. Rainfall rates reached 1 to 3 inches per hour, while thunderstorms repeatedly moved over the same areas.
At Albany, 5.45 inches of rain fell on July 29, shattering the previous daily record of 1.90 inches set in 1974. It was the wettest July day in Albany’s recorded history and the second-wettest calendar day overall.
More importantly, the National Weather Service classified rainfall in parts of eastern New York as a 1-in-1,000-year precipitation event. Schodack recorded 11.79 inches, while Kinderhook received 11.47 inches.

This distinction matters: Albany’s 5.45-inch rainfall was a record, while the 1-in-1,000-year classification applied to portions of the broader eastern New York event.
The Pattern Is Bigger Than a Single Storm
Both Indiana and New York illustrate an important feature of a warming climate: more atmospheric moisture can amplify the intensity of extreme precipitation.
A warmer atmosphere can hold more water vapor—roughly 7% more for every 1°C of warming under the Clausius-Clapeyron relationship.
That does not mean every storm produces 7% more rain. But when atmospheric conditions concentrate and release that additional moisture, rainfall rates can become extreme.
The consequences can compound:
More atmospheric moisture
↓
Higher potential rainfall rates
↓
Repeated heavy thunderstorms
↓
Saturated soils
↓
Rapid runoff
↓
Flash flooding and river flooding
↓
Infrastructure failure and displacement
This is one mechanism through which climate energy becomes a direct physical hazard.
Indiana and New York: From Heat to Flood
The same atmospheric system that stores additional heat and moisture can contribute to seemingly contradictory extremes.
A persistent ridge or heat dome can produce oppressive heat and increase atmospheric moisture demand. When the weather pattern breaks—or when a front, upper-level disturbance, or convective system provides the mechanism for release—the accumulated moisture can produce intense rainfall.
This creates what can be described as hydroclimatic whiplash:
Heat → moisture accumulation → atmospheric instability → extreme rainfall → flooding → rapid transition to another extreme
The sequence is not necessarily a simple one-to-one causal chain. Weather systems remain complex, and individual floods cannot automatically be attributed to climate change without event-specific attribution analysis.
But the physical ingredients are becoming increasingly important: warmer air, greater atmospheric moisture, intense precipitation, saturated soils, and infrastructure designed around historical climate statistics.
New York’s August Severe Weather
The pattern continued into August.
On August 20, severe storms struck the New York metropolitan region and Long Island. A waterspout moved onshore at Atlantic Beach and became a tornado, damaging beach-club structures. Severe flooding also affected Queens and other parts of the region, while emergency responders rescued people from flooded vehicles.
These events occurred within the same summer that eastern New York had already experienced its extraordinary July rainfall.
That is important because climate risk is not simply about isolated record events. Repeated extremes can compound damage.
A community does not have to experience a 1-in-1,000-year event every year to experience a radically different risk environment. A sequence of less-extreme events can saturate soils, overwhelm drainage systems, damage infrastructure, and leave communities increasingly vulnerable when the next storm arrives.
Climate Energy Hitting the Ground
Indiana and New York demonstrate two sides of the same problem.
The atmosphere is not merely becoming warmer. A warmer atmosphere can interact with the water cycle, storm dynamics, soil moisture, rivers, infrastructure, and ecosystems in ways that amplify consequences.
The important question is therefore not simply:
“How often does a 1-in-1,000-year event occur?”
It is:
“What happens when the climate that produced our historical risk statistics is no longer the climate we are living in?”
A 1-in-1,000-year rainfall event is supposed to be extraordinarily rare.
When multiple regions begin experiencing events classified at that level, the lesson is not that every “1-in-1,000-year” event has suddenly become a once-per-year event.
The lesson is that the baseline is changing—and the consequences of that change are already reaching communities, rivers, roads, homes, farms, and public infrastructure.
That is climate energy hitting you where you live.
From Biodiversity to Monoculture: The Socio-Economic-Ecological Feedback Loop
Climate change is often described as a problem of rising temperatures, but temperature is only one expression of the additional energy entering the Earth system.
That energy moves through the atmosphere, hydrologic cycle, soils, vegetation, ecosystems, agriculture, forests, and human economies. As each system responds, it can alter the conditions experienced by the others.
This creates feedback loops.
A recent investigation by the Center for Investigative Reporting found that glyphosate is being sprayed in California forests at record levels. The U.S. Forest Service, timber companies, and other land managers use glyphosate after wildfire or timber harvest to suppress competing vegetation and improve the establishment of commercially valuable conifers.
At first glance, this may appear to be a straightforward forestry practice: kill competing plants, plant trees, and accelerate forest recovery.
But viewed through the lens of climate-system dynamics, it raises a much larger question:
What happens when our response to climate disruption further simplifies the ecosystems we depend upon for resilience?
Climate Energy Is Changing the Recovery Environment
Western forests are already experiencing a combination of higher temperatures, increasing atmospheric moisture demand, changing precipitation and snowpack, declining soil moisture, drought stress, and increasingly severe wildfire.
A forest can experience increasing stress for years without an obvious transformation. Then a threshold can be crossed.
Trees die.
Seed sources disappear.
Regeneration fails.
Shrubs and grasses occupy the landscape.
The ecosystem begins transitioning from one state to another.
As the paper explains, under moderate emissions scenarios, up to 40% of western conifer forests could convert to shrubland or grassland by 2100.
That is not simply forest damage.
It is ecosystem conversion.
And once we recognize that distinction, the economics of post-fire forest management look different.
The Economics of Reforestation
After a major wildfire, rapidly growing shrubs, grasses, ferns, and deciduous vegetation can compete with planted conifer seedlings for water, nutrients, and sunlight.
From a timber-production perspective, that competition is a problem.
Glyphosate provides an efficient way to remove it.
The Forest Service has used herbicide treatments as part of regeneration efforts because suppressing competing vegetation can improve the early survival and growth of desired seedlings. Forest research acknowledges that this is one reason herbicides have been used in reforestation.
The economic objective is therefore understandable:
But that is not necessarily the same objective as:
restore biodiversity → restore ecological function → increase climate resilience.
Those two objectives can overlap.
They can also conflict.
A Forest Is Not a Tree Farm
The distinction matters because a forest is not simply a collection of trees.
A functioning forest contains an enormous biological network:
multiple tree species
shrubs
grasses
flowering plants
fungi and mycorrhizal networks
insects and pollinators
birds
mammals
reptiles and amphibians
soil organisms
decomposers
streams and wetlands
genetic diversity
Each component participates in the functioning of the ecosystem.
When glyphosate is applied to eliminate “competing” vegetation, those plants are competitors only from the perspective of the desired crop.
From the perspective of the ecosystem, they may be food, shelter, habitat, soil cover, pollinator resources, firebreaks, nutrient sources, or participants in water and carbon cycling.
This creates a fundamental difference between restoration and production.
Production asks:
How efficiently can we produce the desired commodity?
Ecological restoration asks:
How effectively can we restore the biological relationships that make the ecosystem resilient?
Biodiversity Is Infrastructure
Biodiversity is often treated as an aesthetic or conservation issue.
It is much more than that.
Biodiversity is a form of ecological infrastructure.
Different species respond differently to drought, heat, insects, disease, fire, and changing precipitation. A diverse ecosystem therefore contains multiple biological responses to disturbance.
If one species performs poorly, another may survive.
If one food source disappears, another may remain.
If one plant cannot regenerate under new climatic conditions, another may occupy the available ecological niche.
This is one reason biological diversity can provide resilience.
A simplified ecosystem has fewer alternatives.
A diverse ecosystem has more.
That distinction becomes increasingly important as climate variability increases.
From Biodiversity to Monoculture
The problem becomes more obvious when forestry is compared with modern industrial agriculture.
Large-scale agriculture often relies on monocultures: enormous areas devoted to a single crop or a very small number of genetically similar crops. Monoculture creates economic efficiencies. Machines can plant, fertilize, spray, harvest, and transport a standardized product at enormous scale. But biological simplification creates vulnerabilities.
A pest that specializes in the crop has an enormous continuous food supply. A disease can spread rapidly through genetically similar plants. Soil nutrients can become depleted. Pollinator and insect diversity can decline. Herbicide and pesticide dependence can increase.
The economic system becomes increasingly dependent upon external inputs to maintain productivity.
The result can be a feedback loop:
biodiversity declines → ecological resistance declines → pests and disease become more consequential → chemical inputs increase → biodiversity declines further.
This is not an argument that all monoculture agriculture inevitably fails.
It is an argument that efficiency and resilience are not the same thing.
The same distinction applies to forestry.
The Forest Monoculture
When post-fire management suppresses naturally regenerating vegetation in order to establish commercially desirable conifers, the landscape can move toward a forest plantation rather than a naturally regenerating forest.
A plantation can contain thousands of trees and still possess considerably less biodiversity than the ecosystem it replaced.
This creates a dangerous semantic trap. We see trees. We call it a forest. But ecological function depends upon far more than tree cover.
A plantation of one or a few commercially valuable species can look green from above while functioning very differently from a diverse forest.
And in a warming climate, that distinction can become critical.
Ecosystem Conversion Versus Reforestation
This is where the concept of ecosystem conversion becomes important.
Suppose a severe wildfire destroys a mature conifer forest.
The original ecosystem does not necessarily return.
Under the warmer and drier conditions described in my Western U.S. Woodlands paper, grasses and shrubs may become better adapted to the post-fire environment than the trees that previously occupied it.
The second pathway is not simply allowing the ecosystem to respond to its new climate. It is imposing an economic land-use objective upon that response. That distinction should be explicit in public policy.
The Carbon Question
There is another important distinction. A green landscape is not necessarily equivalent to the forest that existed before. Grasslands and shrublands photosynthesize and absorb carbon.
So do plantations.
But carbon uptake is not the same thing as carbon storage.
A mature forest contains carbon in:
trunks
branches
roots
dead wood
forest soils
long-lived biomass
The Ecosystem Conversion paper makes this distinction explicitly:
carbon uptake ≠ carbon storage capacity
and
positive carbon flux ≠ preservation of the previous carbon stock.
A plantation may therefore satisfy a narrow definition of reforestation while failing to reproduce the carbon reservoir, biodiversity, hydrology, and ecological complexity of the original forest.
The Glyphosate Feedback
This brings us back to glyphosate. The current controversy is not simply about a herbicide. It is about the interaction between climate disruption, economic incentives, land management, biodiversity, and ecosystem resilience.
The emerging feedback looks something like this:
Climate warming
↓
Heat + drought + atmospheric moisture demand
↓
More severe wildfire
↓
Loss of mature forest
↓
Economic pressure to recover timber production
↓
Herbicide use to suppress competing vegetation
↓
Reduced vegetation diversity
↓
Simplified forest structure
↓
Greater dependence on managed inputs
↓
Potentially reduced ecological resilience
↓
Greater vulnerability to future climate disturbances
This does not mean glyphosate necessarily causes every subsequent step.
The feedback is systemic.
The larger point is that a management strategy designed to optimize one component of a complex system can unintentionally weaken other components.
The Scientific Evidence Must Be Independent
There is also a legitimate question about the evidence used to evaluate glyphosate. The recent investigation found that a study heavily relied upon by the Forest Service in assessing glyphosate safety was subsequently retracted after concerns about Monsanto’s involvement in the research process.That does not establish that every use of glyphosate is unsafe. It does establish why the underlying evidence should be independently reviewed.
When government policy determines what chemicals can be sprayed across public landscapes, the scientific foundation for those decisions should be exceptionally transparent.
Public land requires public confidence. And public confidence requires independent science.
From Wildfire Recovery to a National Policy
The issue also has a national economic dimension.
On February 18, 2026, President Donald Trump signed an executive order titled “Promoting the National Defense by Ensuring an Adequate Supply of Elemental Phosphorus and Glyphosate-Based Herbicides.”
The order invokes the Defense Production Act and directs federal action to ensure an adequate domestic supply of glyphosate-based herbicides. That places glyphosate within a much larger economic framework involving agriculture, forestry, chemical manufacturing, supply chains, and national security.
The feedback becomes:
climate disruption → increased agricultural and forestry stress → greater dependence on chemical intervention → greater economic importance of chemical production → stronger incentives to maintain chemical availability.
The system becomes self-reinforcing.
The Bigger Problem: Optimizing the Wrong Variable
Climate change forces us to rethink what we mean by efficiency. A system can be economically efficient while being ecologically fragile. A monoculture can produce enormous quantities of a commodity while containing very little biological diversity. A plantation can produce timber while failing to reproduce the ecological functions of a natural forest. A landscape can be covered in green vegetation while holding substantially less carbon than the forest it replaced. And a post-fire intervention can accelerate tree planting while simultaneously simplifying the ecosystem that must survive the next climate shock.
The central question is therefore not:
How quickly can we replace the trees we lost?
It is:
What kind of ecosystem will survive the climate that is coming?
The Resilience Test
Climate change is increasing the importance of resilience.
A resilient ecosystem does not necessarily maximize production under ideal conditions.
It maintains function when conditions become abnormal.
That means diversity matters.
Species diversity.
Genetic diversity.
Structural diversity.
Age diversity.
Habitat diversity.
Landscape diversity.
Biological diversity is effectively a portfolio of responses to uncertainty.
Industrial systems tend to reduce that diversity because standardization creates efficiency.
Climate instability does the opposite.
It increases the value of diversity.
That creates one of the central contradictions of the climate era:
The more unstable the climate becomes, the more we need ecological diversity—and the more economic pressure we may face to simplify ecosystems for efficiency.
Climate Energy Is Hitting the Whole System
This is ultimately what I mean by How Is Climate Energy Hitting You?
Climate energy does not stop with a thermometer reading or a measurement of atmospheric carbon dioxide. It moves through the entire coupled human-Earth system.
Heat changes water demand.
Water stress changes forests.
Forest stress changes wildfire.
Wildfire changes ecosystems.
Ecosystem disruption changes economic decisions.
Economic decisions change land management.
Land management changes biodiversity.
Biodiversity changes resilience.
And declining resilience feeds back into the next disturbance.
The resulting system is not a collection of unrelated environmental problems. It is a coupled socio-economic-ecological feedback system in which changes in one component propagate through the others.
Wildfire becomes an economic loss.
Economic loss creates pressure for rapid recovery.
Rapid recovery creates demand for herbicides, machinery, labor, and planted timber.
Those interventions alter ecosystems.
Altered ecosystems influence water, biodiversity, soil, carbon storage, and future fire behavior.
Government policy can then reinforce the economic system that produced the intervention in the first place.
The feedback can therefore become self-reinforcing.
The challenge is to recognize when a short-term economic solution becomes a long-term ecological feedback.
That distinction becomes especially important when an ecosystem crosses a threshold. Restoring the trees may not be the same thing as restoring the forest.
And once biodiversity has been converted into monoculture, replanting the landscape does not necessarily recreate the ecosystem that was lost.
Climate change is not simply changing the weather.
It is changing the decisions we make about the world around us—and those decisions can become feedbacks that determine how resilient that world remains.
Sierra Nevada: Hydroclimatic Whiplash, Atmospheric Rivers, Rain-on-Snow, Droughts, Landslides, Wildfires
The Sierra Nevada is becoming a powerful example of hydroclimatic whiplash—where climate energy intensifies both extremes, shifting California’s water cycle from a relatively predictable seasonal rhythm toward rapid swings between atmospheric-river flooding, premature snowmelt, and summer drought.
Excessive winter moisture associated with El Niño can produce enormous snowfall in the Sierra Nevada. But when warmer temperatures accompany subsequent atmospheric rivers—the so-called Pineapple Express—that snowpack can melt rapidly and weeks or months ahead of schedule.
The result is a dangerous paradox: more winter water can mean less water available when California needs it most.
1. The Rain-on-Snow Flooding Trap
When a warm atmospheric river collides with an existing mountain snowpack, it can produce a rain-on-snow event.
Instead of adding to California’s frozen natural reservoir, warm tropical moisture accelerates snowmelt. Rain also adds its own runoff to the water released from the snowpack, producing a sudden surge of water flowing into rivers and valleys.
The result can be catastrophic flooding, landslides, erosion, and infrastructure damage.
This also shifts flood risk earlier in the year. A water system historically organized around gradual spring and early-summer snowmelt can instead experience major runoff events in the middle of winter.
2. The High-Altitude “Snow Eaters”
A warmer atmosphere can hold roughly 7% more water vapor for every 1°C of warming. When that additional moisture is delivered by powerful atmospheric rivers, storms can become extraordinarily wet.
But temperature determines whether that moisture falls as snow or rain.
As the baseline climate warms, the snowline rises. Elevations that once reliably accumulated snow are increasingly likely to receive rain during warm storms. Water that would have been stored for months as snow instead becomes immediate runoff.
The mountains are therefore losing part of their ability to function as California’s natural reservoir.
3. The Aquifer and Reservoir Disconnect
California’s water infrastructure was largely designed around a seasonal rhythm in which Sierra snowpack acts as a natural storage system.
Snow accumulates during winter and gradually melts during spring and early summer, releasing water over an extended period. That slow release helps sustain rivers, reservoirs, ecosystems, agriculture, and groundwater recharge.
Accelerated snowmelt disrupts that timing.
When enormous volumes of water arrive rapidly, reservoirs can fill much earlier than planned. Water managers may then have to release water to maintain flood-control capacity, even while California faces water shortages later in the year.
And rapid surface runoff is not equivalent to slow, sustained groundwater recharge. When water races through rivers and across saturated landscapes, much of it can move downstream before it has an opportunity to infiltrate deeply into aquifers.
The paradox is profound:
A landscape can experience flooding and groundwater stress within the same water year.
4. The Summer Hangover
The consequences don’t end when the floodwaters recede.
If Sierra snowpack disappears weeks or months earlier than it once did, the mountains enter summer with less stored water. Soils dry earlier. Streams decline sooner. Vegetation loses access to moisture during the hottest part of the year.
That creates a dangerous feedback:
More winter heat → more rain instead of snow → faster snowmelt → greater runoff → less summer snowpack → earlier drying → greater wildfire risk.
The same climate energy that produces extreme winter precipitation can therefore help create extreme summer dryness.
The New Sierra Water Cycle
This is the essence of hydroclimatic whiplash.
California is not simply becoming “wetter” or “drier.” The timing, intensity, and physical form of water are changing.
More atmospheric moisture can arrive in fewer, more intense storms. More precipitation can fall as rain rather than snow. Snowpack can melt earlier. Flooding can occur during winter while groundwater and surface-water supplies become increasingly stressed later in the year.
The Sierra Nevada has long served as California’s natural water tower.
Climate change is increasingly turning that water tower into a system of rapid loading and rapid discharge—delivering too much water too quickly, followed by too little stored water when the summer demand arrives.
The problem isn’t simply how much water California receives. It is when that water arrives, where it goes, and how long the landscape can hold onto it.
North Texas: Drought, Wildfire, Evacuation, Water Scarcity, Livestock Liquidation, Crop Failure
The Ross Fire: Climate Energy on the Ground
The Ross Fire has exploded across more than 50,000 acres of North Texas, triggering mandatory evacuations, school closures, and a major emergency response. Driven by triple-digit heat, exceptionally low humidity, strong winds, and severe drought, the fire is exhibiting extreme behavior and was only about 5% contained as of August 25.
The fire began in Palo Pinto County near Highway 180 and Ross Watson Road and has pushed rapidly northeast toward southern Jack County. Firefighters have reported flames reaching as high as 100 feet, making direct attacks extremely dangerous. Crews have therefore relied heavily on bulldozers and aerial support.
Evacuations and Community Disruption
Mandatory evacuations have been ordered for portions of southern Jack County, including areas near and east of Bartons Chapel and along County Road 2210 toward Highway 281.
An evacuation center has been established at the Twin Lakes Recreation Center on Highway 59 in Jacksboro.
The fire is also disrupting education. On August 25, Perrin CISD canceled all classes, while Jacksboro ISD delayed the beginning of the school day by two hours.
This is more than a wildfire. It is a demonstration of how climate energy moves through a coupled human-environment system: heat dries vegetation, drought removes water from the landscape, wind accelerates fire spread, and communities are forced to evacuate.
Texas Is Drying Out
The Ross Fire is occurring within a much larger regional drought emergency. Drought conditions across Texas have deteriorated rapidly, with approximately 77% of the state experiencing drought. Nearly 200 counties across Texas and Oklahoma have implemented active outdoor burn bans because of elevated fire danger.
A second significant brush fire has also been reported farther south in Hamilton County near Evant, forcing localized evacuations north of Highway 84.
The important point is that wildfire is not an isolated event. Fire is the visible expression of an increasingly dry and heat-loaded landscape.
When extreme heat, low humidity, depleted soil moisture, dry vegetation, and high winds occur simultaneously, their effects are not merely additive. They reinforce one another.
Climate Energy Is Reshaping Texas Agriculture
The same climate pressures driving wildfire are disrupting Texas agriculture and the cattle industry.
Texas agriculture is confronting a convergence of prolonged drought, historic heat, declining water availability, and increasingly volatile precipitation. Together, these stresses are changing the economics of farming and ranching.
The result is not simply a bad growing season.
It is structural disruption.
The Cattle Industry Under Pressure
Shrinking Herds
Depleted water supplies and increasingly parched rangelands have contributed to a major contraction in Texas cattle operations. The Texas cattle herd has fallen from approximately 13.1 million head to about 12 million.
The national beef-cow inventory has also fallen to its lowest level in decades.
Forced Liquidation
When stock ponds empty and forage disappears, ranchers face an increasingly difficult choice: purchase expensive supplemental feed or sell their cattle.
For operations already under financial pressure, purchasing enough hay to maintain a breeding herd may be impossible. Cattle are therefore being sent to auction and slaughter earlier than planned.
Higher prices do not restore the lost water or forage.
The economic consequences therefore continue long after the drought itself begins to ease.
Beef Supply Chains Under Stress
With fewer cattle available, livestock prices are rising sharply. The contraction in cattle inventories is also putting pressure on meat processors.
When there are not enough animals moving through the system, processing facilities can become economically unsustainable. Plant closures then reduce processing capacity and increase the vulnerability of the remaining supply chain.
Climate energy is therefore moving from the atmosphere to the pasture, from the pasture to the rancher’s balance sheet, and from the rancher’s balance sheet to the consumer’s grocery bill.
Crop Agriculture Under Extreme Heat and Drought
Texas is also confronting severe challenges to crop production.
Cotton Crop Failures
Texas is the nation’s leading cotton-producing state, but extreme heat and drought have caused widespread crop stress, crop failures, and abandoned fields.
Sustained triple-digit temperatures can interfere with flowering and reproductive development, reducing yields even when plants survive.
Heat Stress and Water Scarcity
As temperatures rise, crops lose water more rapidly through evapotranspiration.
At the same time, declining soil moisture and groundwater availability make irrigation increasingly difficult and expensive.
This creates another feedback:
Higher temperatures → greater atmospheric demand for water → faster soil drying → greater irrigation demand → declining water availability → higher agricultural costs.
The atmosphere is effectively pulling water out of the agricultural system faster.
Pests and Disease
Climate disruption is also changing the biological environment in which crops are grown.
Changes in temperature and seasonal conditions can allow pests and diseases to expand their ranges, survive through seasons in which they previously could not, or reproduce more rapidly.
Threats including cotton jassid, rice delphacid, and pasture mealybug illustrate how agricultural climate risk extends beyond drought and heat.
Farmers are increasingly confronting a moving target: the climate conditions under which today’s agricultural systems evolved are changing faster than the systems themselves can adapt.
Adaptation: Fighting Back Against Climate Energy
Texas farmers and ranchers are not simply waiting for conditions to improve. Many are experimenting with strategies designed to make agricultural systems more resilient.
Regenerative Ranching
Some ranching operations are adopting rotational and multi-paddock grazing systems designed to improve soil structure, maintain living root systems, and increase water infiltration.
Healthy soils can store substantially more water than degraded soils. Improving soil organic matter and root systems can therefore provide a buffer against drought by allowing more rainfall to infiltrate and remain available to plants.
Adaptation cannot stop the atmosphere from warming.
But it can increase the amount of climate stress an agricultural system can absorb before it fails.
Carbon Farming
Managed grasslands can also store carbon in soils while improving soil health and water retention.
Carbon farming therefore has the potential to provide multiple benefits: improved pasture productivity, greater drought resilience, healthier soils, and additional revenue through carbon markets where those markets are viable.
Statewide Disaster Planning
Texas is also attempting to improve its institutional response to increasingly complex agricultural hazards.
The Texas Department of Agriculture has established the Texas Agriculture Disaster Task Force to coordinate responses to threats including wildfire, freezes, drought, and biosecurity emergencies.
That kind of planning recognizes an increasingly important reality:
Climate disasters do not occur one at a time.
A drought can increase wildfire risk.
A wildfire can destroy forage.
Heat can intensify drought.
Drought can reduce crop yields.
Crop failures can increase food prices.
Water shortages can force livestock liquidation.
And all of these pressures can occur simultaneously.
The Bigger Picture: Climate Energy Is Cascading Through the System
The Ross Fire is therefore more than 50,000 acres of burning vegetation.
It is one visible manifestation of a larger climate-energy cascade.
Drought → depleted forage and water → cattle liquidation → smaller herds → constrained beef supplies → higher prices
These are not independent problems.
They are connected expressions of the same physical system.
Climate change adds energy to the atmosphere. That additional energy intensifies the hydrologic cycle, increases atmospheric demand for water, amplifies heat extremes, and changes the timing and intensity of precipitation.
The result is increasing volatility: longer dry periods interrupted by more intense rainfall, greater heat stress, rapidly drying landscapes, and wildfire conditions that can emerge with extraordinary speed.
How Is the Climate Energy Hitting You?
In North Texas, it is hitting as drought, wildfire, evacuation, water scarcity, livestock liquidation, crop failure, and rising agricultural costs.
The Ross Fire makes the process impossible to ignore.
The fire is burning on the landscape.
The drought is draining the landscape.
And the climate energy driving both is increasingly reaching the farm, the ranch, the grocery store, and the household.
Climate change is not merely changing the weather.
It is changing the systems that depend upon the weather.
Many people believe that planting trees is one of the most important ways to help save the planet and reverse climate change. Planting trees can certainly help—but planting a tree and growing a healthy, mature forest are two very different things.
The problem is that climate change is increasing the stresses that kill trees and changing where forests can survive. Rising temperatures, increasing vapor pressure deficits, drought, extreme heat, wildfire, flooding, disease, and insect outbreaks are interacting in ways that can overwhelm trees faster than forests can adapt.
Wildfire is an increasingly important part of the problem. Climate-driven increases in fire weather have contributed to substantially greater forest and tree-cover losses in many regions. Drought and extreme heat compound that damage by reducing soil moisture and increasing atmospheric demand for water. In warmer air, a higher vapor pressure deficit (VPD) increases the drying power of the atmosphere, causing trees to lose water through their leaves faster and potentially creating hydraulic stress when roots cannot keep up.
Tree mortality is also occurring through less spectacular but equally important pathways. Long-term studies have documented increasing mortality in some tropical forests, while drought, heat, insects, and disease have produced severe die-offs in temperate and boreal forests. In California, prolonged drought and heat have contributed to the death of tens of millions of trees. Elsewhere, drought and increasingly volatile weather have reduced the survival of newly planted trees and complicated reforestation efforts.
This creates a fundamental problem with the simple “plant more trees” solution.
A planted seedling must first survive. Then it must grow large enough to become ecologically significant, reproduce, and ultimately become part of a functioning forest. A tree that dies after a few years has absorbed only a fraction of the carbon it might have stored over decades—and the resources invested in planting it may accomplish little. Multiple prominent scientific studies and forestry reports confirm that replanted saplings face staggering failure rates, with mortality exceeding 70% to 80% within 5-to-10-years.
That is why tree survival matters as much as tree planting.
Multiple studies of reforestation and tree establishment have found substantial seedling mortality, particularly under drought, heat, competition, poor site conditions, and other environmental stresses. Mortality can become extremely high when newly planted trees encounter conditions outside the climate range to which they are adapted.
The question for the future, therefore, is not simply:
How many trees can we plant?
It is:
Which trees can survive long enough to become the forests of tomorrow?
That is the question behind this experiment.
Penn’s Sylvania: Penn’s Woods
On March 4, 1681, King Charles II granted William Penn a royal charter for a vast tract of land in North America. The grant contained more than 28 million acres, making it one of the largest private land grants in history. The King awarded the territory to Penn partly to settle a debt of £16,000 owed to Penn’s late father, Admiral Sir William Penn.
But the story behind the name is especially fitting for a state whose identity is so closely tied to its forests.
William Penn wanted to call his new territory “Sylvania,” from the Latin silva, meaning woodland or forest. In other words, Penn envisioned a land defined by its woods.
King Charles II, however, insisted that “Penn” be placed before Sylvania to honor Admiral William Penn. The result was Pennsylvania—literally, “Penn’s Woods.”
Penn reportedly worried that people would assume he had named the colony after himself, when the name was actually the King’s tribute to his father.
More than three centuries later, the name remains remarkably appropriate.
Penn’s Sylvania was a land of forests.
The question now is whether the forests that gave Pennsylvania its name can survive the rapidly changing climate of the land itself.
Penn’s Sylvania Experiment
Since the 1960s, I have studied trees in Pennsylvania. Over the decades, I have watched the conditions affecting our forests change—and, more recently, deteriorate rapidly. Several factors are driving this decline, including ozone pollution, hydroclimatic whiplash, and ecosystem conversion.
The goal is not simply to document what is happening, but to find ways to adapt to the conditions we have now while working to change the trajectory that is producing them.
Unfortunately, “native species” is not necessarily the answer—at least not without defining what we mean by native and, more importantly, native to when? A species that evolved in Pennsylvania under the climate of the past may not necessarily be well suited to Pennsylvania’s rapidly changing climate today.
That is the premise behind this experiment.
I transplanted trees that began sprouting naturally around my property, along with trees I obtained for free or on special occasions. Some were Arbor Day giveaways. Others were small ornamental trees purchased at post-Christmas sales. Nothing particularly scientific or selective went into acquiring them. They were simply trees that became available to me.
For several years, I have been testing these trees for climate resilience in my location.
That may be one of the most useful ways to identify the trees of the future: an evolving experiment conducted where you actually live. There is no single “best tree” for tomorrow because tomorrow’s climate is still changing—and the speed and acceleration of that change remain uncertain.
One of the most troubling findings is that many of the species we traditionally regard as Pennsylvania’s native trees are struggling under today’s conditions. Some of the old-growth species that once thrived here may no longer be capable of surviving, much less thriving, under the climate they now face.
The question, then, is not simply “What trees are native here?”
It is:
“What trees can survive here as the climate continues to change?”
