Spoiled Soil

What Is Happening to the Dirt Beneath Your Feet?

Most people think of soil as nothing more than dirt. In reality, healthy soil may be one of the most important—and overlooked—parts of Earth’s climate system. Unlike the atmosphere, oceans, or glaciers, soil is alive.

A single handful of healthy soil contains billions of living organisms: bacteria, fungi, insects, earthworms, and countless other forms of life. Together, they recycle nutrients, store carbon, filter water, and support nearly every plant on Earth. Without healthy soil, there is no healthy ecosystem.

The Planet’s Crossroads

Soil is unique because it lies at the intersection of Earth’s major systems. Scientists classify it as its own domain, the pedosphere (from the Greek pedon, meaning soil or earth).

The pedosphere connects four planetary spheres:

  • Atmosphere (Air): Soil constantly exchanges oxygen, carbon dioxide, methane, and water vapor with the atmosphere.
  • Hydrosphere (Water): Soil absorbs, stores, filters, and slowly releases water, acting like a giant natural sponge.
  • Lithosphere (Rock): Soil forms from the weathering of rock into sand, silt, clay, and minerals.
  • Biosphere (Life): Soil is home to an astonishing diversity of plants, fungi, microbes, insects, and animals.

                Lithosphere

Because every one of these systems depends on healthy soil, changes in soil often reveal changes occurring throughout the entire Earth system.

Soil: A Living Climate Indicator

Healthy soil stores enormous amounts of carbon—more than the atmosphere and all vegetation combined. It also regulates water, reduces flooding, supports agriculture, and provides habitat for countless organisms.

When soil begins to deteriorate, it serves as an early warning that multiple environmental systems are under stress.

Unfortunately, human activities are placing unprecedented pressure on soils worldwide. Climate change, deforestation, intensive agriculture, pollution, and urban development are accelerating soil degradation faster than many ecosystems can recover.

Hydroclimatic Whiplash

One of the clearest examples is hydroclimatic whiplash—rapid swings between severe drought and intense rainfall.

Extended drought weakens vegetation, dries out soils, kills soil organisms, and greatly increases wildfire risk.

Then the weather often swings in the opposite direction.

Atmospheric rivers, microbursts, and other extreme rain events produce intense runoff that washes away the already damaged landscape. Instead of soaking into healthy soil, the water carries ash, sediment, nutrients, and debris into streams, rivers, and lakes.

This creates a cascade of environmental damage.

When Fire Meets Flood

Scientists refer to these events as post-wildfire runoff or rain-on-wildfire events.

The chain reaction can be devastating:

  • Ash and debris cloud the water and block sunlight.
  • Microorganisms rapidly consume the incoming organic material, using up dissolved oxygen.
  • Nutrients such as nitrogen and phosphorus trigger algal blooms that later consume even more oxygen as they decay.
  • Changes in water chemistry stress or kill aquatic organisms.

The result is often a fish kill, caused by hypoxia (dangerously low oxygen) or anoxia (complete oxygen depletion).

What began as a wildfire on land becomes an ecological disaster throughout an entire watershed.

Losing One of Earth’s Greatest Carbon Sinks

Healthy soils are among Earth’s largest natural carbon sinks. As soils degrade, they lose their ability to store carbon and instead may release additional greenhouse gases into the atmosphere.

The consequences extend far beyond agriculture.

Degraded soils contribute to:

  • Desertification
  • Savannization
  • Reduced biodiversity
  • Lower crop yields
  • Increased flooding
  • Greater wildfire risk
  • Faster climate change

Each of these impacts can reinforce the others, creating self-amplifying feedback loops that become increasingly difficult to reverse.

Why Scientists Are Concerned

Many scientists are studying whether some of Earth’s major ecosystems are approaching critical tipping points.

One of the most closely watched examples is the Amazon rainforest. Continued warming, drought, deforestation, and fire could reduce parts of the forest’s ability to sustain itself, transforming sections into a drier, more open landscape. While considerable uncertainty remains about exactly where these thresholds lie, growing evidence suggests that several Earth systems are becoming less resilient.

The challenge is no longer simply determining whether tipping points exist.

It is identifying where they are, how quickly we are approaching them, and how multiple feedback loops may interact to accelerate change.

The paper Amazon Rainforest Dieback: Emerging Risks, Feedback Loops, and Scenario-Based Projections illustrates the processes of ecosystem collapse and savannization.

The Ground Beneath Our Feet

We often look to melting glaciers, rising seas, stronger storms, or record-breaking temperatures as signs of climate change.

But one of the clearest indicators may be much closer.

The dirt beneath your feet is not just dirt.

It is a living ecosystem, a massive carbon reservoir, a water filter, the foundation of agriculture, and the meeting place of Earth’s atmosphere, water, rock, and life.

If the soil is becoming less healthy, it is a warning that the entire planetary system is under increasing stress.

The next time you stand on the ground, consider this question:

What is happening to the soil beneath your feet?

Climate Change and a Backyard Produce Experiment: Results Through July 2026

Production Results

ProduceProduction
PlumsExcellent
CherriesPoor
ApplesPoor
TomatoesBelow Average
RaspberriesPoor
PotatoesAverage
BeansAverage

Introduction

The results of this backyard produce experiment closely reflect the climate-related agricultural challenges affecting Southeastern Pennsylvania through July 2026. The region has experienced increasing climate volatility, often described as “weather whiplash”—a pattern characterized by unusually warm winter and early spring conditions followed by damaging late-season freezes, summer heat waves, and increasingly erratic precipitation.

The observed performance of each crop corresponds closely with the climatic stresses documented throughout the region.

Analysis by Crop Type

1. Tree Fruit Losses: Cherries and Apples

Both cherries and apples produced poor yields, mirroring the severe losses reported by many Pennsylvania fruit growers.

Climate Driver:
Warmer winters and early springs are causing fruit trees to break dormancy and bloom earlier than historical averages.

The False Spring Effect:
Following an unusually warm early spring, a significant late-season freeze struck Pennsylvania. Because many cherry and apple trees had already reached vulnerable flowering stages, blossoms were damaged or destroyed. Trees subsequently aborted damaged fruitlets, resulting in dramatically reduced harvests.

Observed Result: Poor production.

2. Heat-Stressed Crops: Tomatoes and Raspberries

Tomatoes and raspberries showed substantial sensitivity to elevated summer temperatures.

Climate Driver:
Repeated heat waves during June and July 2026 produced prolonged periods with temperatures exceeding 95°F (35°C).

Botanical Impacts:

  • Raspberries possess shallow root systems that are highly vulnerable to heat stress and soil moisture fluctuations. Prolonged high temperatures can reduce berry size, quality, and overall production.
  • Tomatoes often experience blossom drop when both daytime and nighttime temperatures remain elevated. Flowers fail to pollinate successfully, reducing fruit set and overall yield.

Observed Results:

  • Raspberries: Poor
  • Tomatoes: Below Average

3. Resilient Crops: Potatoes and Beans

Potatoes and beans demonstrated greater resilience despite challenging weather conditions.

Climate Driver:
Although extreme heat occurred, the season also included intermittent rainfall events that helped maintain soil moisture.

Botanical Impacts:

  • Potatoes benefit from underground tubers that remain insulated from extreme air temperatures.
  • Beans are generally adaptable and capable of maintaining stable production across a wider range of environmental conditions.

Observed Results:

  • Potatoes: Average
  • Beans: Average

4. The Plum Exception

Plums were the clear standout of the experiment, producing an excellent harvest despite widespread challenges affecting other fruit crops.

Climate Driver:
Most stone fruit in the region faced significant frost damage. However, localized factors can substantially alter outcomes.

Possible Explanations:

  • Favorable microclimate conditions
  • Higher-elevation planting sites where cold air drains away
  • Natural frost protection from surrounding terrain
  • Orchard management practices that reduced freeze damage

The plums were planted at the highest point on the property and were well protected by surrounding trees. Their elevated location likely reduced frost exposure, while the surrounding trees helped moderate temperature fluctuations and wind. Together, these conditions likely protected the blossoms from the damaging late-spring frosts that devastated many other fruit trees. The exceptional performance of the plum crop suggests that site-specific conditions—including elevation, natural wind protection, and frost mitigation—can significantly improve a crop’s resilience to climate-related stresses.

Observed Result: Excellent production.

Production Comparison and Climate Correlation

ApplesPoorFrost-damaged blossoms and fruitletsFalse spring freeze
TomatoesBelow AverageReduced fruit set during heat wavesSummer heat stress
RaspberriesPoorHeat stress and moisture challengesExtreme temperatures
PotatoesAverageProtected underground growthSoil temperature buffering
BeansAverageAdaptable growth characteristicsClimate resilience

Conclusions

This small-scale produce experiment provides a useful illustration of how climate change is increasingly influencing agricultural outcomes in Southeastern Pennsylvania.

The results reflect a broader regional pattern:

  • Early warming followed by hard freezes disproportionately impacts tree fruits such as apples and cherries.
  • Extreme summer heat reduces yields of temperature-sensitive crops such as tomatoes and raspberries.
  • Root crops and legumes generally demonstrate greater resilience to short-term temperature extremes.
  • Microclimate advantages can sometimes offset regional climate pressures, as demonstrated by the exceptional plum harvest.

Key Finding

The experiment suggests that Southeastern Pennsylvania’s increasing climate variability—particularly the combination of false springs, late freezes, and extreme summer heat—is creating clear winners and losers among common food crops. Delicate flowering fruit trees experienced the greatest losses, while more resilient crops maintained average production levels despite challenging conditions.

bookmark_borderThe Two Sides of the Climate Crisis: Consumption and Production

Posted on by admin

by Daniel Brouse

Climate change is often discussed as a problem of emissions, but emissions are the result of two interconnected forces: consumption and production.

Q: What are the greatest drivers of climate change?
A: Consumption and production.

At present, I would rank our addiction to consumption and ecofascism as the two most significant drivers of the climate crisis. While they operate in different ways, both reinforce the systems that accelerate environmental degradation.

The Consumption Problem

The United States, Western Europe, Canada, and Australia represent some of the world’s most consumption-driven economies. When self-interest, materialism, and short-term economic incentives dominate decision-making, consumer demand becomes one of the primary drivers of climate change, influencing not only greenhouse gas emissions but also land-use change, deforestation, habitat destruction, water consumption, resource depletion, and biodiversity loss.

This is why consumption-based accounting provides a more accurate picture of climate responsibility than production-based accounting alone.

For example, if a smartphone is manufactured in Asia using coal-generated electricity and then shipped across the Pacific to a consumer in Los Angeles, the emissions from mining, manufacturing, transportation, and delivery are ultimately driven by the purchasing decision. Under consumption-based accounting, those emissions are attributed to the American consumer rather than solely to the country where the phone was manufactured.

Read the full explanation and view the rankings here:

http://membrane.com/global_warming/Accounting-for-Climate-Responsibility.html#the-carbon-we-own

The Production Problem

The production side of the equation is likewise influenced by self-interest and economic incentives, but it is also shaped by ideological movements that obstruct effective climate action.

Two distinct, though sometimes overlapping, ideologies are particularly important:

Denialism is characterized by the rejection of scientific evidence, refusal to engage with empirical data, and reliance on misinformation or rhetorical distraction. Its primary objective is often the protection of political, ideological, or economic interests by undermining the scientific consensus.

Ecofascism combines elements of denialism with authoritarian, exclusionary, or extremist beliefs. In its most extreme forms, it portrays environmental collapse as acceptable—or even desirable—because it is viewed as reducing populations or preserving resources for groups considered more deserving than others. This ideology has historically been associated with racist, xenophobic, or eugenicist beliefs and rejects principles of equality and shared human responsibility.

The distinction is important. Traditional denialism primarily seeks to delay or prevent climate policy. Ecofascism goes further by framing unequal human survival as an acceptable or even desirable outcome — eliminationist logic.

Why This Matters

Climate change is not simply a technological or economic challenge. It is also a question of values.

On one side, excessive consumption drives demand for fossil fuels, resource extraction, and emissions. On the other, ideologies that reject science or rationalize unequal human suffering weaken society’s ability to respond effectively to the crisis.

Both sides must be addressed if meaningful progress is to be made.

Further Reading

While investigating climate change denialism, I examined material that I believe illustrates the intersection between denialist narratives and extremist environmental ideologies. A summary of that research is available here:

Posted on by admin

The Composite Climate Responsibility Index (CCRI): A Lifecycle, Population-Normalized Framework for Measuring State-Level Climate Responsibility

Abstract

Greenhouse gas accounting has traditionally relied on territorial emissions—the greenhouse gases emitted within a political boundary. While this approach provides a standardized framework for national and subnational reporting, it systematically underestimates the climate responsibility of fossil fuel-producing regions by excluding upstream methane releases, fossil fuel extraction, refining, petrochemical processing, and liquefied natural gas (LNG) operations. Consequently, jurisdictions that export carbon-intensive fuels often appear to have disproportionately low climate impacts relative to the emissions they enable elsewhere.

This paper introduces the Composite Climate Responsibility Index (CCRI), a lifecycle-based, population-normalized metric that integrates direct emissions with upstream and industrial contributions to provide a more comprehensive assessment of climate responsibility. By incorporating territorial emissions, extraction activities, processing emissions, and upstream methane releases, CCRI captures the complete climate burden associated with fossil fuel production. Normalizing by population further facilitates equitable comparisons among jurisdictions of vastly different sizes.

The resulting framework reveals that many energy-exporting states possess per-capita climate burdens several times larger than those suggested by conventional inventories. CCRI offers policymakers, researchers, and the public a more representative metric for evaluating climate responsibility and designing equitable mitigation strategies.

1. Introduction

Climate policy has historically focused on territorial greenhouse gas inventories reported under the United Nations Framework Convention on Climate Change (UNFCCC). These inventories assign emissions to the jurisdiction in which they physically occur. While appropriate for international reporting, territorial accounting does not fully represent the climate impacts associated with fossil fuel production.

For example, coal mined in Wyoming may ultimately be combusted in Texas or overseas. Natural gas extracted in Pennsylvania may be liquefied in Louisiana and consumed in Europe or Asia. Existing inventories allocate combustion emissions to the point of use while largely excluding the upstream activities that make fossil fuel consumption possible.

This accounting structure creates a disconnect between production and responsibility. Fossil fuel-producing regions often exhibit relatively modest reported emissions despite facilitating substantially larger global greenhouse gas releases.

The Composite Climate Responsibility Index addresses this limitation by expanding the accounting boundary to include the entire fossil fuel production chain.

2. Conceptual Framework

Climate responsibility extends beyond smokestacks and tailpipes.

Every fossil fuel undergoes a sequence of climate-relevant processes before combustion:

  • Exploration
  • Extraction
  • Processing
  • Transportation
  • Storage
  • Distribution
  • Combustion

Current inventories emphasize the final stages while giving comparatively little weight to the earlier phases, despite substantial emissions from methane leakage, venting, flaring, compressor stations, refineries, LNG facilities, and petrochemical complexes.

The CCRI recognizes these emissions as integral components of fossil fuel production rather than incidental byproducts.

3. Definition of the Composite Climate Responsibility Index

The Composite Climate Responsibility Index is defined as

[
\boxed{
CCRI=
\frac{
E_{\text{territorial}}
+
E_{\text{upstream}}
+
E_{\text{processing}}
+
E_{\text{extraction}}
}
{P}
}
]

where

  • (E_{\text{territorial}}) represents direct greenhouse gas emissions occurring within the jurisdiction;
  • (E_{\text{upstream}}) represents methane leakage, venting, flaring, compressor emissions, gathering systems, and other fugitive emissions occurring prior to end-use combustion;
  • (E_{\text{processing}}) represents emissions associated with petroleum refining, LNG facilities, petrochemical production, natural gas processing plants, and related industrial infrastructure;
  • (E_{\text{extraction}}) represents emissions directly associated with coal mining, oil production, natural gas extraction, drilling, pumping, and associated operations;
  • (P) represents the jurisdiction’s population.

The resulting metric is expressed as

metric tons CO₂-equivalent per capita per year.

4. Advantages Over Traditional Inventories

Traditional greenhouse gas inventories answer the question:

“How much greenhouse gas is emitted inside this state?”

CCRI instead asks:

“How much climate forcing is generated because this state produces fossil fuels?”

This distinction fundamentally changes state rankings.

Large population centers often dominate territorial emissions because of transportation and electricity demand.

However, production-based accounting reveals that relatively small states can exert disproportionately large global climate impacts through fossil fuel extraction and processing.

5. Components of the Index

5.1 Territorial Emissions

These include all greenhouse gases released within state boundaries, including

  • electricity generation
  • transportation
  • industrial processes
  • residential and commercial energy use
  • agriculture
  • waste management

These values are generally available through EPA greenhouse gas inventories.

5.2 Upstream Emissions

Upstream emissions include

  • methane leakage
  • venting
  • flaring
  • abandoned wells
  • gathering pipelines
  • compressor stations
  • storage facilities

Methane is particularly important because its near-term warming potential greatly exceeds that of carbon dioxide.

Failure to include upstream methane significantly underestimates the climate burden of natural gas production.

5.3 Processing Emissions

Processing emissions include

  • oil refining
  • LNG liquefaction
  • petrochemical production
  • fertilizer manufacturing
  • hydrogen production from fossil fuels
  • natural gas processing

Many refining states emit relatively modest territorial greenhouse gases compared with the enormous climate impacts associated with processing fossil fuels destined for global markets.

5.4 Extraction Emissions

Extraction includes

  • coal mining
  • drilling operations
  • hydraulic fracturing
  • pumping
  • mining equipment
  • dewatering
  • mine methane
  • associated infrastructure

Coal-producing regions often exhibit exceptionally large extraction-related emissions.

6. Why Population Matters

Absolute emissions measure scale.

Per-capita emissions measure responsibility.

Population normalization allows meaningful comparisons between states of vastly different sizes.

For example, Texas produces the largest absolute climate burden in the United States because of its enormous oil, gas, refining, petrochemical, and power sectors.

Conversely, Wyoming’s small population means that its production-related emissions translate into one of the highest per-capita climate burdens in the world.

Thus, CCRI distinguishes between total contribution and individual responsibility.

7. Policy Applications

CCRI provides policymakers with several advantages.

It can

  • identify regions with disproportionate upstream emissions;
  • improve methane reduction strategies;
  • prioritize investments in emissions monitoring;
  • support equitable climate policy;
  • inform carbon pricing mechanisms;
  • evaluate fossil fuel subsidies;
  • guide transition assistance for energy-producing regions;
  • improve state-to-state comparisons.

Because CCRI incorporates lifecycle emissions, it aligns more closely with the physical drivers of climate change than territorial inventories alone.

8. Illustrative Results

Applying the framework to U.S. states suggests that fossil fuel-producing regions dominate per-capita climate responsibility.

Illustrative rankings include:

  1. Wyoming
  2. North Dakota
  3. West Virginia
  4. New Mexico
  5. Louisiana
  6. Alaska
  7. Oklahoma
  8. Texas
  9. Pennsylvania
  10. Kentucky

These rankings differ substantially from traditional greenhouse gas inventories, which are dominated by population size rather than fossil fuel production.

9. Limitations

Like all composite indicators, CCRI depends on the quality of underlying datasets.

Future refinements should incorporate

  • satellite methane observations,
  • lifecycle emission factors,
  • temporal variability,
  • exported fossil fuel carbon content,
  • uncertainty analysis,
  • probabilistic confidence intervals.

Additional weighting schemes may also be developed to distinguish short-lived climate pollutants from long-lived greenhouse gases.

10. Conclusion

The Composite Climate Responsibility Index represents a significant advancement in greenhouse gas accounting by extending responsibility beyond territorial emissions to encompass the complete fossil fuel production chain. It recognizes that extraction, processing, and upstream methane emissions are not peripheral activities but essential components of the carbon economy.

By integrating these sources and normalizing by population, CCRI offers a more comprehensive measure of climate responsibility than traditional inventories. It reveals that many jurisdictions with modest reported emissions play an outsized role in enabling global fossil fuel consumption, while densely populated states often appear less carbon-intensive when viewed through a production-based lens.

As climate policy evolves toward lifecycle accounting and supply-side mitigation, the Composite Climate Responsibility Index provides a transparent, scalable, and scientifically grounded framework for evaluating the true climate burden associated with fossil fuel production. It complements existing territorial inventories rather than replacing them, offering decision-makers a broader perspective on responsibility, equity, and the pathways toward effective emissions reduction.

Posted on by admin

by Daniel Brouse

A Global Climate System Under Increasing Stress

The most destructive climate disasters of 2026 reveal a rapidly changing pattern: extreme events are becoming more intense, more widespread, and increasingly interconnected.

From deadly heatwaves across Europe and South Asia to catastrophic flooding and severe storms across the United States, this year’s disasters demonstrate how human-caused warming is amplifying natural climate variability.

Scientific attribution studies from organizations such as World Weather Attribution (WWA) have repeatedly shown that greenhouse gas emissions are increasing the severity, duration, and likelihood of many modern climate extremes. Climate change is not replacing natural weather patterns—it is shifting the baseline conditions in which those patterns occur, turning historically rare events into recurring hazards.

1. Global Heatwaves and Heat Domes — The Deadliest Climate Hazard of 2026

Extreme heat has emerged as the defining climate disaster of the year, affecting billions of people across South Asia, Europe, the Middle East, and North America.

South Asia: Record-Breaking Pre-Monsoon Heat

India and Pakistan experienced a prolonged pre-monsoon heatwave, with temperatures repeatedly exceeding 46°C (115°F) in multiple cities.

The extreme heat disrupted agriculture, increased energy demand, threatened outdoor workers, and placed millions of vulnerable people at risk.

Climate Connection:
World Weather Attribution researchers concluded that human-caused warming significantly intensified the event, making such prolonged extreme heat far more likely than under historical climate conditions.

Europe: Over 10,000 Excess Deaths from Extreme Heat

Europe experienced one of the most severe heat disasters in modern history as persistent heatwaves pushed temperatures 5–12°C above average in some regions.

France, Spain, the United Kingdom, and other European nations experienced record-breaking temperatures, widespread drought stress, increased wildfire danger, and severe impacts on public health.

The heat contributed to more than 10,000 excess deaths, with older adults and people with underlying health vulnerabilities experiencing the greatest risks.

These deaths highlight the growing recognition that extreme heat is one of the deadliest consequences of climate change, often exceeding the immediate fatalities associated with storms and floods.

Climate Connection:
Attribution studies have concluded that human-caused climate change substantially increased the intensity and probability of these European heat extremes by raising the global temperature baseline.

The Hajj Heat Disaster: Climate Risks in a Warmer World

In Mecca, Saudi Arabia, extreme heat during the Hajj pilgrimage created dangerous conditions for millions of participants.

The combination of intense solar exposure, high humidity, and prolonged outdoor activity pushed temperatures beyond historically safe thresholds, producing hundreds of heat-related illnesses and significant loss of life.

Climate Connection:
Fossil fuel emissions have expanded the duration and severity of dangerous heat conditions in the region, increasing risks for large outdoor gatherings.

2. The Emerging Super El Niño: A Climate Amplifier

The extreme weather of 2026 is occurring alongside a strengthening El Niño event in the tropical Pacific.

El Niño is a natural climate cycle that periodically transfers large amounts of ocean heat into the atmosphere. However, it is now occurring on top of record global ocean temperatures driven by greenhouse gas emissions.

This creates a climate multiplier effect, increasing the likelihood of:

  • Record-breaking temperatures
  • Extreme rainfall events
  • Flash flooding
  • Agricultural disruption
  • Expanding drought conditions

The interaction between natural variability and human-caused warming is producing a more unstable and energetic climate system.

Major U.S. Climate Disasters of 2026

1. Summer Heat Dome and Wildfire Smoke Envelope — Largest Human Exposure

The most widespread U.S. climate disaster of the year was a massive heat dome combined with wildfire smoke spreading across the continent.

More than 120 million Americans from Minnesota to Massachusetts experienced heat alerts and hazardous air quality conditions.

Major metropolitan areas including Chicago, Detroit, New York, and Washington, D.C., experienced some of the worst air quality conditions in the world as smoke from Canadian wildfires moved southward.

Climate Connection:
Hotter and drier conditions have expanded wildfire activity, with North American wildfire acreage reaching approximately 146% of the 10-year average. Climate change is increasing the likelihood of persistent heat domes, drought conditions, and larger wildfire seasons.

2. January North American Winter Storm — Highest Early-Year Death Toll

A massive winter storm swept across the United States and Atlantic Canada, producing extreme cold, freezing temperatures, ice accumulation, and infrastructure failures.

The storm caused more than 173 deaths, making it one of the deadliest weather events of the year.

Climate Connection:
Although winter storms remain natural phenomena, warmer oceans and a warmer atmosphere allow storms to carry more moisture, increasing the potential for heavier precipitation, extreme snowfall, and more damaging freeze events.

3. Central and Southeastern Tornado Outbreak — Largest Severe Storm Damage

A three-day severe weather outbreak in March produced more than 95 confirmed tornadoes, causing approximately $2.3 billion in damage.

The storms moved from Illinois into Mississippi, Alabama, and Georgia, producing destructive tornadoes, damaging winds, and widespread infrastructure impacts.

Climate Connection:
A warmer atmosphere contains more heat and moisture, increasing atmospheric instability and creating conditions favorable for more intense severe thunderstorms.

4. Mid-Summer Flash Flood Disasters — The Fastest Escalating Threat

Extreme rainfall events produced catastrophic flash flooding across parts of Texas Hill Country, West Virginia, and the Ohio Valley.

Communities experienced emergency declarations, water rescues, landslides, infrastructure failures, and overwhelmed emergency systems.

Climate Connection:
Because the atmosphere holds approximately 7% more moisture for every 1°C of warming, climate change is increasing the potential for sudden, extreme rainfall events that overwhelm drainage systems and communities.

2026 Climate Disaster Overview

Disaster CategoryKey 2026 IndicatorMajor Impact Areas
Extreme HeatRecord-breaking heatwaves and >10,000 European excess deathsEurope, South Asia, Middle East, North America

Severe Storms$2.3 billion tornado outbreakIllinois, Mississippi, Alabama, Georgia
Flash FloodingMultiple emergency declarationsTexas Hill Country, West Virginia, Ohio Valley
Winter Storms173+ fatalitiesUnited States and Atlantic Canada

A New Era of Compound Climate Disasters

The defining feature of 2026 is not simply that individual disasters are becoming stronger—it is that climate extremes are increasingly interacting.

Heat intensifies drought.
Drought fuels wildfires.
Wildfires spread smoke across continents.
Warmer oceans energize storms.
A warmer atmosphere produces heavier rainfall.

These cascading interactions represent a transition from isolated weather events to a more interconnected climate risk system.

The challenge of the coming decades will not only be adapting to a warmer planet, but managing a climate system where multiple extreme events increasingly occur together, amplify one another, and create cascading impacts across societies and ecosystems.

bookmark_borderWhat Are the Odds? An Estate Plan for the Next Seven Generations

Posted on by admin

by Daniel Brouse and Sidd Mukherjee

When I began this journey more than three decades ago, I wasn’t a climate researcher. I was a financial planner specializing in business, economics, estate planning, and risk management. My academic background included economics, philosophy, and extensive study in physics, calculus, statistics, and systems analysis. My career focused on a simple question:

How do you create the best possible future for the people who come after you?

In the early 1990s, I met a brilliant scientist named Sidd. We shared a curiosity about complex systems and a desire to test ideas rather than simply debate them. Together, we began an experiment that has now spanned more than thirty years.

Our goal was unusual. We wanted to build what we jokingly called a one-size-fits-all, bulletproof shareware estate plan—not for one family, but for every family on Earth.

At the same time, I was helping pioneer some of the earliest privately owned web servers. Before commercial hosting became commonplace, we were operating online while many organizations were still connected through universities. It was the same era when Yahoo! itself was running from Stanford University.

By 1995, our website, KingArthur.com, was attracting millions of visitors each month. The internet gave us something few researchers had ever possessed: the ability to interact directly with millions of people across cultures, countries, religions, and generations.

One question became central to our experiment:

“When it comes to your life and what you leave behind, what is the single most important thing?”

We expected many people to answer with wealth, success, fame, or legacy.

Instead, they overwhelmingly answered something much simpler.

Among people under fifty, the most common answer was their children.

Among those over fifty, the answer shifted to their grandchildren.

The experiment revealed something profound. The greatest wealth most people hope to preserve is not money. It is the opportunity for future generations to experience the same joys they have experienced themselves.

In other words, the ultimate estate plan is remarkably simple:

To my children’s children’s children.

The greatest inheritance most of us hope to leave is not a larger bank account. It is the chance for our descendants to raise children of their own, watch them grow, and someday become grandparents themselves.

When we began this experiment, I did not have grandchildren.

Today I do.

That changes everything.

Coincidentally, I was recently asked a question that perfectly captured the purpose of this work:

“Can you play with me on this? I’m wearing my nutritional ecologist hat here, and I’m in a municipal-level discussion that is trying to zoom out seven generations while also identifying the baby steps needed over the next four-year election cycle.”

My immediate thought was:

Exactly.

That is what this experiment has always been about.

An estate plan should not end with our children—or even our grandchildren. It should extend seven generations into the future.

My grandchildren deserve the opportunity to become grandparents themselves. Their grandchildren deserve the same opportunity.

That is entirely achievable—but only if we make wise decisions today.

The graph that follows illustrates that idea.

Every choice we make now influences the range of possible futures available to the next seven generations.

Some outcomes are relatively optimistic. Some involve increasing climate disruption.

Some are far more severe.

Importantly, human extinction remains a low-probability outcome.

The far more likely future is not one of sudden extinction, but one that spans a spectrum of increasing disruption—affecting ecosystems, agriculture, infrastructure, economies, public health, migration, and regional habitability.

The probabilities are not fixed. They are shaped by the decisions humanity makes over the coming decades.. including today.

That changes the conversation entirely.

The question is no longer:

“Are humans going extinct?”

The more important question is:

“How difficult do we want life to be for the next seven generations?”

That question naturally leads to practical priorities:

  • Reduce destructive extraction of fossil fuels and natural resources.
  • Transition to cleaner and more resilient energy systems.
  • Protect and restore forests, wetlands, and other ecosystems.
  • Build infrastructure capable of withstanding future climate conditions.
  • Integrate Indigenous ecological knowledge alongside modern science.
  • Prepare communities to adapt to unavoidable change.

The most important message is this:

We are not acting because humanity is doomed.

We are acting because humanity is not doomed.

Our choices today determine how much hardship future generations inherit.

Ultimately, this is not simply a discussion about climate change.

It is an estate planning exercise on a planetary scale.

The question is no longer how warm the planet becomes.

The question is how well civilization—and the generations that follow us—can endure as environmental change accelerates faster than our ability to adapt.

We cannot rewrite the laws of physics. But we can decide how much pollution we continue to add to the atmosphere.

The most effective step we can take is also the simplest:

Stop burning fossil fuels as quickly and responsibly as possible, while building a more resilient world for the generations that follow.

How Coupled Climate Feedbacks Are Changing Earth’s Behavior

Abstract

For much of the modern scientific era, Earth’s major climate oscillations were studied as largely independent systems. Phenomena such as the El Niño–Southern Oscillation (ENSO), the Atlantic Meridional Overturning Circulation (AMOC), the Arctic Oscillation (AO), the Pacific Decadal Oscillation (PDO), the Indian Ocean Dipole (IOD), and the Atlantic Niño/Niña each possessed recognizable patterns, historical relationships, and reasonably predictable behavior.

Today, however, a growing body of observations suggests these systems are becoming increasingly interconnected through shared reservoirs of heat, moisture, ice, and atmospheric circulation. Rather than behaving as isolated oscillators, they are evolving into a tightly coupled network in which disturbances propagate across multiple components of the Earth system. This increasing connectivity reduces the reliability of historical climate relationships and contributes to what can be described as the collapse of climate predictability.

From Independent Oscillators to a Coupled System

Classical climatology often treated Earth’s major modes of variability as separate oscillations whose interactions were relatively weak and occurred over well-defined time scales.

Examples include:

  • El Niño–Southern Oscillation (ENSO)
  • Atlantic Meridional Overturning Circulation (AMOC)
  • Arctic Oscillation (AO)
  • Pacific Decadal Oscillation (PDO)
  • Indian Ocean Dipole (IOD)
  • Atlantic Niño/Niña

These oscillations remain useful conceptual tools, but they no longer appear to behave as isolated components. Instead, they increasingly exchange energy through atmospheric circulation, ocean heat transport, cryospheric change, and hydrologic feedbacks.

The climate system is transitioning from a collection of loosely connected oscillators to a highly interconnected nonlinear network.

The Common Driver: Earth’s Growing Energy Imbalance

The increasing coupling among climate systems is not random.

It is driven by a steadily increasing accumulation of heat within the Earth system.

More than 90 percent of the excess energy trapped by greenhouse gases is absorbed by the oceans. Rising ocean heat content increases evaporation, atmospheric water vapor, sea surface temperatures, and latent heat available to storms. At the same time, declining sea ice reduces Earth’s reflectivity, allowing additional solar energy to be absorbed. Melting glaciers introduce freshwater into the oceans, altering circulation patterns, while warming soils and thawing permafrost release additional greenhouse gases.

These processes all originate from the same growing energy imbalance, linking climate systems that historically behaved more independently.

Emerging Climate Couplings

Numerous examples illustrate this increasing interconnectedness.

Super El Niño–Atlantic Niña

Exceptional Pacific warming modifies atmospheric circulation, strengthening Atlantic trade winds and promoting cooling in portions of the tropical Atlantic. The altered Atlantic circulation then feeds back into global atmospheric patterns, influencing hurricane development, African rainfall, and Amazon precipitation.

Arctic Amplification–Jet Stream Coupling

Rapid Arctic warming weakens the north-south temperature gradient that maintains the polar jet stream. The resulting slower, more meandering jet stream favors persistent blocking patterns, prolonged heat domes, stalled storms, and extended droughts. Those weather extremes further accelerate Arctic warming through enhanced ice loss and wildfire activity.

Greenland Melt–AMOC Coupling

Accelerated melting of the Greenland Ice Sheet introduces freshwater into the North Atlantic, reducing salinity and slowing deep-water formation. A weaker AMOC alters weather patterns across the Northern Hemisphere, changing precipitation and temperature patterns that can further influence Greenland’s mass balance.

Marine Heatwaves–Atmospheric Rivers

Warmer oceans increase evaporation and atmospheric moisture. Enhanced water vapor intensifies atmospheric rivers, producing heavier precipitation while simultaneously reinforcing marine heatwaves through changes in ocean mixing and heat distribution.

Permafrost–Wildfire–Atmosphere Coupling

Permafrost thaw releases methane and dries peatlands, increasing wildfire activity. Wildfires emit greenhouse gases and black carbon, which darkens snow and ice surfaces, accelerating melting and further warming high-latitude regions.

Forest Dieback–Rainfall Coupling

Forests recycle enormous quantities of moisture through evapotranspiration. As forests decline from heat, drought, or wildfire, atmospheric moisture recycling weakens, reducing rainfall and increasing drought severity, which in turn accelerates additional forest loss.

Why Predictability Is Declining

Historically, climate forecasting relied heavily on recurring relationships.

Meteorologists and climatologists could often estimate future conditions because the underlying oscillations behaved within relatively stable statistical boundaries.

As coupling strengthens, those assumptions become increasingly unreliable.

A disturbance originating in one ocean basin can now propagate through atmospheric circulation into multiple ocean basins, alter sea surface temperatures elsewhere, modify jet stream behavior, influence storm tracks, and feed back into the original disturbance.

Small changes no longer remain local.

Instead, they cascade through interconnected systems.

The result is increasing uncertainty, even while the underlying driver—Earth’s growing energy imbalance—continues to strengthen.

A Network of Nonlinear Feedbacks

This transition is fundamentally a problem of nonlinear dynamics.

In linear systems:

  • responses are generally proportional to the forcing;
  • disturbances remain localized; and
  • historical relationships remain relatively stable.

In nonlinear systems:

  • small perturbations can produce disproportionately large responses;
  • interactions among multiple feedback loops amplify disturbances; and
  • outcomes become increasingly sensitive to initial conditions.

As climate systems become more strongly coupled, Earth’s behavior increasingly resembles a nonlinear network rather than a collection of independent oscillators.

This is the climate-scale manifestation of the Butterfly Effect.

Cascading Climate Responses

Once coupling strengthens sufficiently, climate events begin propagating across multiple systems.

For example:

Ocean Warming → Marine Heatwaves → Increased Evaporation → Higher Atmospheric Water Vapor → Stronger Atmospheric Rivers → Extreme Flooding → Reduced Snowpack → Earlier Runoff → Hotter Soils → Stronger Heat Domes → Additional Ocean Warming

Each step reinforces subsequent processes, creating cascading responses that are considerably larger than the original perturbation.

Beyond Traditional Climate Variability

Many recent extreme events have exceeded expectations based on historical climate statistics.

Persistent heat domes, multi-day atmospheric rivers, marine heatwaves, rapid intensification of tropical cyclones, widespread wildfire outbreaks, and simultaneous extremes occurring across multiple continents increasingly reflect the behavior of an interconnected system rather than isolated weather anomalies.

The climate is no longer responding solely through individual oscillations.

It is responding through interactions among oscillations.

A New Framework for Climate Science

Understanding future climate risk increasingly requires moving beyond analyses that focus on individual climate modes in isolation.

Future prediction will depend on understanding:

  • cross-basin ocean interactions;
  • atmospheric teleconnections;
  • cryosphere–ocean coupling;
  • biosphere–atmosphere feedbacks;
  • hydrologic amplification; and
  • nonlinear propagation through coupled climate networks.

The central scientific challenge is no longer identifying individual feedbacks, but understanding how those feedbacks interact simultaneously.

Conclusion

The growing accumulation of heat within Earth’s climate system is strengthening connections among atmospheric, oceanic, cryospheric, and biological processes. These interactions are transforming once largely independent climate oscillations into a coupled network of nonlinear feedbacks.

As coupling intensifies, disturbances spread more efficiently across the Earth system, historical relationships become less reliable, and extreme events increasingly exceed expectations derived from the past. The resulting decline in predictability is not evidence that the climate has become random. Rather, it reflects the behavior of a highly interconnected nonlinear system whose responses are increasingly governed by cascading interactions instead of isolated processes.

The collapse of climate predictability is therefore best understood not as the failure of climate science, but as the emergence of a new climatic regime—one in which understanding the connections between Earth’s major systems becomes as important as understanding the systems themselves.

Posted on by admin

by Daniel Brouse

Introduction: Climate Change as an Economic and Human Security Crisis

Climate change is no longer only an environmental challenge; it has become a powerful macroeconomic threat multiplier that amplifies existing social, economic, and public health vulnerabilities. Rising temperatures, increasingly extreme weather events, deteriorating air quality, and destabilized ecosystems are creating cascading financial pressures that extend from governments and businesses to individual households.

The economic consequences of climate change are increasingly visible through three interconnected pathways:

  1. Escalating healthcare costs caused by heat exposure, air pollution, infectious diseases, and climate-related disasters.
  2. Erosion of living standards through inflationary pressures on food, energy, insurance, housing, and public infrastructure.
  3. Declining human longevity as environmental stressors undermine physical health, increase mortality, and reverse decades of progress in life expectancy.

These impacts are not distributed equally. Low-income households, elderly populations, outdoor workers, and marginalized communities often face the greatest exposure while having the fewest resources to adapt. Climate change therefore transforms environmental instability into a localized economic and human health crisis.

I. Escalating Healthcare Costs: Climate Change as a Global Medical Expense Multiplier

Climate change is placing unprecedented strain on healthcare systems by increasing both the frequency and severity of climate-related illnesses while simultaneously disrupting healthcare infrastructure.

1. Trillions of Dollars in Climate-Driven Health Burdens

The financial consequences of climate-related health impacts are expected to reach historic levels.

  • The World Bank estimates that climate-related health crises could impose approximately $21 trillion in additional costs by 2050 across low- and middle-income countries, reflecting increased disease burdens, reduced productivity, and expanding healthcare needs.
  • The World Economic Forum estimates that climate change could create approximately $1.1 trillion in additional global healthcare costs over the same period.

These costs represent more than direct medical expenses. They include lost productivity, reduced workforce participation, premature mortality, emergency response requirements, and infrastructure adaptation.

2. Pollution-Related Healthcare Expenses

Climate change and fossil fuel combustion are closely linked. Rising temperatures accelerate atmospheric chemical reactions that increase ground-level ozone formation, intensifying smog episodes and worsening respiratory and cardiovascular disease.

Fine particulate matter (PM2.5), ozone, wildfire smoke, and other pollutants contribute to:

  • Asthma and chronic respiratory illness
  • Heart attacks and strokes
  • Lung disease
  • Premature deaths
  • Increased emergency room visits

In the United States alone, soot and smog pollution are estimated to generate hundreds of billions of dollars annually in health-related costs, including medical expenses and lost economic productivity.

The growing frequency of wildfire smoke events demonstrates how climate impacts can transform regional air pollution into a national health emergency. Smoke from distant wildfires can travel thousands of miles, exposing millions of people far from the original source.

3. Healthcare Infrastructure and Supply Chain Disruptions

Extreme weather events increasingly threaten the operational stability of healthcare systems.

Climate-related disruptions include:

  • Hospitals losing electrical power during heat waves, hurricanes, and wildfires
  • Flooding damaging medical facilities
  • Disruptions in pharmaceutical and medical equipment supply chains
  • Increased emergency response costs
  • Higher insurance and operational expenses for healthcare providers

Hospitals are being forced to spend billions on climate resilience measures, including backup power systems, flood protection, cooling infrastructure, and emergency preparedness.

II. Eroding Standard of Living: Climate Change as a Cost-of-Living Accelerator

Climate change is increasingly becoming an economic reality experienced directly through household budgets. The same forces increasing healthcare costs are also driving inflationary pressures throughout the economy.

1. Climate Inflation and Agricultural Instability (“Agflation”)

Food systems are among the most climate-sensitive sectors of the global economy.

Rising temperatures, droughts, flooding, changing precipitation patterns, and extreme storms reduce agricultural productivity by damaging:

  • Crop yields
  • Livestock health
  • Fisheries
  • Agricultural infrastructure
  • Transportation networks

These disruptions create supply-side inflation, increasing prices for essential goods including:

  • Grains
  • Fruits and vegetables
  • Meat and dairy products
  • Transportation-dependent food products

Climate-driven food inflation disproportionately harms lower-income households because food represents a larger percentage of their monthly expenses.

2. Rising Insurance Costs and the Retreat From High-Risk Regions

The insurance industry has become one of the clearest economic indicators of accelerating climate risk.

As hurricanes, wildfires, floods, and severe storms become more frequent and destructive:

  • Insurance premiums increase dramatically.
  • Coverage becomes more restricted.
  • Insurers withdraw from vulnerable markets.
  • Property values decline in high-risk regions.

Homeowners increasingly face a difficult choice: pay rapidly increasing premiums or assume greater financial risk without adequate coverage.

This creates a growing climate affordability crisis, particularly for homeowners living in areas exposed to wildfire, coastal flooding, extreme storms, and severe weather.

3. Rising Energy Demand and Utility Costs

Climate change increases energy demand while simultaneously placing stress on energy infrastructure.

During extreme heat events:

  • Electricity consumption rises sharply due to increased air conditioning demand.
  • Utilities must invest billions in grid upgrades.
  • Transmission systems require additional protection against storms and wildfires.
  • Maintenance costs are passed onto consumers.

The result is a climate feedback loop:

Hotter temperatures → Greater cooling demand → Higher electricity consumption → Increased infrastructure costs → Higher household energy bills

Energy insecurity becomes a growing concern as vulnerable households struggle to afford cooling during dangerous heat events.

4. Taxpayer Costs and Public Financial Burdens

Climate disasters increasingly redirect public resources away from long-term investments toward emergency response and recovery.

Government spending is increasingly allocated toward:

  • Disaster relief
  • Infrastructure repairs
  • Emergency housing assistance
  • Flood recovery
  • Wildfire response
  • Agricultural assistance

These expenditures compete directly with funding for:

  • Education
  • Transportation improvements
  • Community development
  • Public health programs

Climate change therefore functions as a long-term fiscal drain, increasing government expenditures while reducing resources available for economic development.

III. Declining Human Longevity: Climate Change as a Biological Stressor

Beyond economic impacts, climate change increasingly affects the fundamental measure of human well-being: life expectancy.

The cumulative effects of extreme heat, pollution exposure, disease expansion, food insecurity, and climate disasters are slowing—and in some regions reversing—historical gains in longevity.

Climate DriverImpact on Human Health and Longevity
Rising Global TemperaturesA 2024 study published in PLOS Climate found that a 1°C increase in global average temperature is associated with approximately a 0.44-year reduction in life expectancy.
Extreme HeatwavesHuman-caused climate change is estimated to contribute to approximately 37% of heat-related deaths. Heat-related mortality among adults over age 65 has increased substantially over recent decades.
Expanded Disease Vector RangesWarmer and wetter conditions allow mosquitoes, ticks, and other disease vectors to expand into new regions, increasing risks from malaria, dengue fever, Lyme disease, and other infections.
Food and Water StressClimate disruption increases risks of malnutrition, dehydration, agricultural failure, and water insecurity, particularly in vulnerable populations.
Indirect Disaster MortalityFloods, hurricanes, wildfires, and other disasters create long-term health impacts through displacement, economic hardship, psychological stress, and environmental contamination.

IV. The Climate-Economy-Health Feedback Loop

Climate change creates a reinforcing cycle:

Climate Change → Extreme Weather → Economic Losses → Higher Costs → Reduced Adaptation Capacity → Greater Vulnerability → Increased Health Impacts

This feedback loop means climate impacts are not isolated events. A wildfire, flood, or heat wave can simultaneously damage infrastructure, increase healthcare expenses, reduce productivity, raise insurance costs, and shorten human lives.

The poorest communities often experience the strongest effects because they have fewer resources to prepare, recover, and relocate.

Conclusion: Climate Stability Is Economic Stability

Climate change represents one of the largest economic and public health challenges of the modern era. Its consequences extend far beyond environmental degradation, affecting national budgets, household finances, healthcare systems, and human survival.

The emerging reality is clear:

  • Climate change increases healthcare expenditures.
  • Climate change accelerates inflationary pressures.
  • Climate change reduces economic security.
  • Climate change threatens human longevity.

Addressing climate change is therefore not simply an environmental investment—it is an economic resilience strategy and a public health imperative. Investments in clean energy, resilient infrastructure, pollution reduction, efficient buildings, and climate adaptation can reduce future costs while protecting both human health and economic stability.

The cost of inaction is no longer measured only in degrees of warming. It is measured in rising medical bills, shrinking household budgets, damaged communities, and lost years of human life.

bookmark_borderIce in a Warming World: Climate Change, Giant Hail, and the Nonlinear Escalation of Severe Convective Storms

Posted on by admin

by Daniel Brouse

Climate Change and Hailstorms

One of the most common misconceptions about climate change is that a warmer planet should produce less ice. In reality, the opposite is increasingly true for severe thunderstorms. While winters are warming and snow cover is declining in many regions, the atmosphere is becoming more energetic, more moisture-laden, and more capable of producing exceptionally large hail.

Hailstorms illustrate one of the central themes found throughout modern climate science: global warming is not simply making the planet warmer—it is making the atmosphere more unstable. The climate system is undergoing a nonlinear increase in available energy, atmospheric moisture, and circulation instability. The result is not gradual change, but an acceleration toward more powerful and destructive weather extremes.

Hail is one manifestation of this broader transition.

Severe Convective Energy Events

Hailstorms are among the most energetic convective weather systems on Earth. They develop inside powerful thunderstorms where intense upward air currents repeatedly lift developing ice particles through layers of supercooled water.

Each trip through the storm adds another layer of ice.

If the updraft remains strong enough, hailstones continue growing until gravity finally overcomes the upward force.

The stronger the storm, the larger the hail.

Large hail has become one of the fastest-growing sources of weather-related insurance losses worldwide, producing billions of dollars in damage each year to:

  • Homes
  • Roofs
  • Windows
  • Solar panels
  • Vehicles
  • Crops
  • Electrical infrastructure
  • Aircraft

Unlike heavy rainfall, which loses much of its kinetic energy through atmospheric friction, hailstones maintain tremendous momentum. Baseball-sized hail can strike the ground at speeds exceeding 100 mph (160 km/h), while the largest hailstones exceed 150 mph.

At those velocities, hail becomes a dangerous projectile capable of causing severe injuries and fatalities.

A Warmer Atmosphere Produces Bigger Hail

The same physical processes described in previous papers—especially the increasing atmospheric water vapor driven by the Clausius-Clapeyron relationship—also fuel hail growth.

Every degree Celsius of warming allows the atmosphere to hold approximately 7% more water vapor.

That additional moisture provides thunderstorms with more latent heat energy.

When this latent heat is released during condensation, it strengthens thunderstorm updrafts dramatically.

The result is a positive feedback:

  • More warming
  • More atmospheric moisture
  • More latent heat release
  • Stronger thunderstorms
  • Stronger updrafts
  • Larger hail

This is another example of Earth’s climate system amplifying itself through reinforcing feedback loops rather than responding linearly.

Updrafts: Nature’s Giant Ice Factory

Imagine a lava lamp operating at maximum power.

Instead of blobs of wax rising through liquid, enormous columns of warm, moisture-rich air accelerate upward through the atmosphere.

Inside these towers:

  • Water droplets freeze.
  • Ice particles are lifted thousands of feet upward.
  • Supercooled water freezes onto existing hailstones.
  • The growing hailstone falls.
  • The updraft catches it again.
  • Another layer forms.

This process repeats many times.

The stronger the updraft, the longer the hailstone remains suspended.

Eventually the hailstone becomes too heavy.

Then gravity wins.

The result is giant hail capable of catastrophic destruction.

As climate warming strengthens convective energy, these powerful updrafts are becoming increasingly common.

Why Small Hail Is Declining

Climate change does not necessarily increase every type of hail.

In fact, many regions may experience fewer small hail events.

This occurs because freezing levels are rising.

As temperatures increase:

  • Snow melts sooner.
  • Ice melts higher in the atmosphere.
  • Small hailstones completely melt before reaching the ground.
  • Large hailstones survive.

The result is a dramatic shift in hail size distribution.

Instead of numerous harmless pea-sized hailstones, storms increasingly produce fewer—but much larger and more destructive—hailstones.

Current projections suggest that by the end of this century:

  • Large hail events may increase by 38–47%
  • Small hail events may decrease by 4–8%

This represents another example of the climate system shifting toward extremes rather than averages.

Geography Is Changing

Historically, the world’s most active hail regions included:

  • The U.S. Great Plains
  • Argentina
  • South Africa
  • Northern India
  • Central Europe

Today, climate models suggest these regions are changing.

Increasing hail environments are projected across:

  • The U.S. Midwest
  • Ohio Valley
  • Northeast
  • Southeastern United States
  • Canada
  • Northern Europe
  • New Zealand’s South Island

The traditional “Hail Alley” of the Great Plains is expected to expand eastward while favorable atmospheric conditions migrate poleward as global temperatures rise.

These geographic shifts mirror changes already observed in atmospheric rivers, jet stream behavior, and storm tracks.

Changing Seasons

The timing of severe hailstorms is also evolving.

Rather than occurring primarily during midsummer, favorable conditions are increasingly appearing during:

  • Early spring
  • Late fall
  • Even portions of winter

Warmer winters allow severe thunderstorms to develop during months that historically experienced relatively stable atmospheric conditions.

This creates new risks for agriculture.

Winter wheat and other cool-season crops become increasingly vulnerable to destructive hail during critical stages of development.

Climate Change Is Increasing Financial Losses

Few weather hazards have produced such rapidly escalating insured losses.

Since 2008:

  • U.S. hail-related insurance claims have increased approximately fivefold.
  • Annual insured losses now regularly exceed tens of billions of dollars.
  • Vehicle damage has become one of the largest components of weather-related insurance costs.

One of the most striking recent examples occurred in northern Italy during 2023.

A series of severe thunderstorms produced approximately $8.6 billion in damages while dropping a European-record hailstone measuring nearly 19 centimeters (7.5 inches) in diameter.

Across North America, giant hail is increasingly damaging:

  • Solar farms
  • Wind facilities
  • Data centers
  • Warehouses
  • Airports
  • Distribution centers

As urban development expands into storm-prone regions, exposure continues to rise even as the storms themselves become more intense.

The result is a compounding economic feedback between climate risk and infrastructure vulnerability.

Human Safety

Although hail is often viewed as primarily a property hazard, it is increasingly becoming a public health concern.

Large hail can:

  • Cause traumatic brain injuries
  • Fracture bones
  • Damage eyesight
  • Kill livestock
  • Trigger multi-vehicle accidents
  • Force aircraft into emergency landings

As giant hail events become more common, so do reports of injuries and fatalities.

The danger is amplified because hail often accompanies tornadoes, destructive straight-line winds, flash flooding, and frequent lightning, creating multiple simultaneous hazards.

A Symptom of a More Energetic Climate

Large hail is not an isolated phenomenon.

It is part of the same global pattern documented throughout this body of work.

The accelerating increase in atmospheric water vapor, ocean heat content, jet stream instability, atmospheric rivers, bomb cyclones, extreme rainfall, wildfire behavior, and severe convective storms all point to the same underlying driver:

An atmosphere containing more energy.

As Arctic amplification weakens the temperature gradient between the poles and the tropics, atmospheric circulation becomes increasingly distorted. Rossby waves become more amplified, blocking patterns persist longer, and weather systems slow or stall. At the same time, warmer oceans and land surfaces inject additional heat and moisture into the atmosphere, providing more fuel for explosive thunderstorms.

When these large-scale circulation changes coincide with abundant moisture and intense surface heating, the result is an environment capable of generating stronger updrafts, larger hail, heavier rainfall, more damaging winds, and more frequent tornado outbreaks. Hail therefore should not be viewed as an isolated weather event, but as one expression of a broader shift toward higher-energy atmospheric dynamics.

The Shift to Extremes

One consistent pattern emerges:

Climate Change → Energy Imbalance → More Atmospheric Moisture + Greater Instability → Stronger Storm Dynamics → More Frequent & More Severe Weather Extremes → Hotter Heat Waves → Wetter Atmospheric Rivers → Larger Wildfires → More Intense Flash Floods → Stronger Hurricanes → Giant Hailstorms

This is the hallmark of nonlinear climate change: a progressive shift from moderate conditions toward increasingly severe outcomes as Earth’s energy imbalance grows. Hail is another visible indicator that the climate system is moving beyond historical norms, where extremes become more common and their impacts more costly.

Understanding hail in this broader context helps connect individual weather disasters to the larger transformation underway in the Earth’s climate system. Rather than isolated anomalies, these events are increasingly linked by the same physical processes: rising atmospheric moisture, greater available energy, and amplifying feedbacks that are reshaping weather across the globe.

bookmark_borderAir Pollution Protection: Practical Strategies for a Changing Climate

Posted on by admin

by Daniel Brouse

Reducing Exposure to Smoke, Ozone, and Fine Particulate Pollution

Climate change, air pollution, and human health are becoming increasingly intertwined in a self-reinforcing feedback system. Rising temperatures accelerate the formation of ground-level ozone, while hotter, drier conditions fuel larger and more frequent wildfires that release enormous quantities of smoke and toxic gases. These pollutants damage human health, weaken forests and ecosystems that normally absorb carbon dioxide, and further accelerate climate change.

Protecting yourself from air pollution is no longer just a concern during isolated pollution events—it has become an essential part of climate resilience.

1. Avoid Exposure Whenever Possible

The most effective protection against air pollution is to avoid breathing polluted air whenever possible.

Monitor local air quality forecasts daily, especially during:

  • Wildfire events
  • Heat waves
  • Temperature inversions
  • High ozone alerts
  • Dust storms
  • Heavy traffic periods

Air quality is commonly reported using the Air Quality Index (AQI), which primarily measures particulate pollution (PM₂.₅ and PM₁₀). However, harmful pollutants such as ground-level ozone (O₃), nitrogen dioxide (NO₂), sulfur dioxide (SO₂), and numerous volatile organic compounds (VOCs) can fluctuate rapidly and may not always be reflected by a single AQI number.

Ground-level ozone deserves special attention because it is largely invisible. Peak ozone concentrations often occur on warm, sunny afternoons when ultraviolet (UV) radiation drives chemical reactions between nitrogen oxides (NOₓ) and volatile organic compounds released from vehicles, power plants, industrial facilities, and wildfire smoke.

Clear skies do not necessarily mean clean air. Even when the AQI appears acceptable, hot, sunny, and stagnant conditions can rapidly generate dangerous levels of ground-level ozone. If these conditions are present, use your best judgment and limit outdoor activity.

2. Wear Appropriate Respiratory Protection

Sometimes avoiding outdoor exposure is impossible. When you must be outside, proper respiratory protection becomes essential.

Particulate Pollution

For wildfire smoke and airborne particles:

  • N95 respirators
  • KN95 respirators
  • P100 respirators

These masks are highly effective at filtering fine particulate matter (PM₂.₅) when they fit properly.

Ozone and Toxic Gases

Particulate masks alone do not protect against gases.

Ground-level ozone, formaldehyde, benzene, and many wildfire gases pass directly through standard N95 and HEPA filters.

Protection from gaseous pollutants requires:

  • Activated carbon filters
  • Activated charcoal cartridges
  • Combination particulate/carbon respirators

Activated carbon chemically adsorbs many gaseous pollutants before they reach your lungs.

3. Improve Indoor Air Quality

Staying indoors greatly reduces exposure to outdoor air pollution, but indoor air can still become contaminated by infiltrating smoke, ozone, and other outdoor pollutants, as well as indoor sources such as cooking emissions, cleaning products, and volatile organic compounds (VOCs) released from furniture, flooring, paints, adhesives, and building materials.

Improving indoor air quality is one of the most cost-effective investments in personal health. However, there is an important trade-off. Better insulation and tighter building construction improve energy efficiency by reducing heating and cooling losses, but they also reduce the natural exchange of indoor and outdoor air. Without adequate ventilation and air filtration, pollutants generated indoors can accumulate to unhealthy levels. Conversely, older or less airtight homes provide greater natural ventilation but also allow more outdoor pollutants—including wildfire smoke, ozone, pollen, and fine particulate matter—to enter the living space.

The ideal solution is to combine a well-sealed, energy-efficient building with controlled ventilation and high-quality air filtration. Mechanical ventilation systems equipped with MERV-rated filters and activated carbon filtration, along with portable air cleaners such as Corsi–Rosenthal Boxes, can maintain healthy indoor air while minimizing the infiltration and buildup of harmful pollutants.

The Corsi–Rosenthal Box

One of the least expensive and most effective air-cleaning systems is the Corsi–Rosenthal Box.

Developed during the COVID-19 pandemic, this simple do-it-yourself air purifier combines:

  • A standard box fan
  • One to five high-efficiency furnace filters (typically MERV-13)

Together they create an air filtration system capable of removing large quantities of airborne particles, often matching or exceeding the performance of many commercial HEPA air purifiers costing hundreds of dollars.

A basic version requires only:

  • one box fan
  • one MERV-13 furnace filter

The fan’s suction often holds the filter securely in place without tape.

Adding four filters in the familiar cube design increases airflow while reducing resistance, producing an exceptionally efficient whole-room air cleaner.

For homes experiencing recurring wildfire smoke, many experts recommend operating at least one Corsi–Rosenthal Box continuously during smoke events on each floor.

Removing Indoor Ozone

Particle filters—including fiberglass filters, MERV filters, and HEPA filters—do not remove ozone.

Removing ozone requires activated carbon.

Granular or pelletized activated carbon filters are particularly effective because they provide large surface areas for chemical reactions.

As ozone (O₃) passes through activated carbon, it reacts with the carbon surface and is converted primarily into ordinary oxygen (O₂), substantially reducing indoor ozone concentrations.

Many high-quality air purifiers now combine:

  • HEPA filtration for particles
  • Activated carbon for gases

This combination provides protection against both wildfire smoke and ozone.

For more information about building a Corsi–Rosenthal Box, see:

http://membrane.com/global_warming/Corsi-Rosenthal-Box.html

4. Use Indoor Plants as Supplemental Air Filters

Indoor plants can improve local air quality while providing numerous psychological and environmental benefits.

NASA’s landmark Clean Air Study identified several plants that help absorb volatile organic compounds (VOCs) released from furniture, carpets, paints, adhesives, and household cleaners.

Among the most effective are:

  • Peace Lily
  • Snake Plant
  • Spider Plant
  • Golden Pothos
  • Boston Fern

These plants can reduce concentrations of compounds such as:

  • formaldehyde
  • benzene
  • xylene
  • trichloroethylene

However, modern research has shown that although plants are helpful in small spaces, extremely large numbers of plants would be required to equal the air-cleaning capacity of a modern HVAC system.

Indoor plants should therefore be viewed as a supplement—not a replacement—for mechanical air filtration.

The best strategy combines:

  • healthy ventilation
  • Corsi–Rosenthal Boxes
  • activated carbon filtration
  • indoor plants

Together these provide layered protection against both particulate and gaseous pollutants.

5. Practice Personal Decontamination

Air pollution does not only enter the body through the lungs.

Smoke particles, soot, pollen, heavy metals, and chemical residues accumulate on the skin, hair, clothing, and facial features throughout the day.

After returning indoors following exposure:

  • Wash your face thoroughly.
  • Shower if exposure was prolonged.
  • Wash your hair.
  • Change contaminated clothing.
  • Rinse exposed skin with soap and water.

Special attention should be given to:

  • eyebrows
  • eyelashes
  • nostrils
  • ears

These areas naturally trap airborne particles before they enter deeper into the respiratory system. Removing accumulated contaminants helps maintain the effectiveness of these natural protective barriers while reducing continued exposure indoors.

People who wear contact lenses may also benefit from removing and cleaning them after heavy smoke or pollution exposure, as pollutants can irritate the eyes and adhere to lens surfaces.

6. Long-Term Protection

While personal protective measures reduce individual exposure, they cannot eliminate the growing threat posed by worsening air pollution.

Long-term protection requires reducing the underlying causes of pollution by limiting greenhouse gas emissions, improving energy efficiency, reducing fossil fuel combustion, preventing catastrophic wildfires, and protecting forests and wetlands that naturally filter the atmosphere.

As climate change accelerates, episodes of dangerous air quality are expected to become more frequent, longer-lasting, and geographically widespread. Preparing homes with effective air filtration, maintaining appropriate respiratory protection, and staying informed about local air quality conditions are becoming essential components of climate adaptation.

Conclusion

The atmosphere is changing rapidly, bringing with it increasing levels of wildfire smoke, ground-level ozone, fine particulate matter, and other airborne pollutants. These hazards threaten respiratory health, cardiovascular function, neurological well-being, and overall quality of life.

Fortunately, many of the most effective protective measures are simple and affordable. Monitoring air quality, minimizing outdoor exposure during pollution events, using properly fitted respirators, improving indoor air filtration with systems such as the Corsi–Rosenthal Box, incorporating activated carbon filtration, maintaining indoor plants, and practicing thorough personal hygiene can dramatically reduce daily exposure.

As climate-driven air pollution becomes an increasingly common reality, proactive protection is no longer optional—it is an essential part of safeguarding both individual health and community resilience.
