Taking the Temperature of Climate Change

Bend Over

Much of the world is focused on 1.5°C.

One reason the public has become so focused on this number is its simplicity. A 1.5°C (2.7°F) increase sounds like a straightforward, easily understood concept. It also doesn’t sound particularly frightening. After all, what’s the big deal about a couple of degrees of warming? Some people even portray it as potentially beneficial.

Scientists take a very different view.

There are many ways to look at climate change. At the micro level, millions of individual feedbacks are operating throughout the Earth system—between the atmosphere, oceans, ice, land, ecosystems, and human systems. At the macro level, all of those interactions combine to form a single, interconnected climate system.

The critical question is not simply how much the planet warms, but what happens as warming changes the system itself.

Understanding how these feedbacks interact—and, more importantly, how they amplify one another—is at the bleeding edge of climate science. The climate system is not a simple thermostat in which each additional degree produces a proportionally larger but otherwise predictable effect. It is a complex, nonlinear system capable of crossing thresholds and shifting into fundamentally different states.

That is why 1.5°C matters.

The 1.5°C threshold identified in the Paris Agreement—and the roughly 2°C level generally regarded as an even more dangerous boundary—is not important because the difference between 1.4°C and 1.5°C is somehow magical. These numbers matter because increasing global temperatures raise the probability of triggering major climate tipping points.

And once tipping points begin to activate, the question of whether warming ultimately reaches 2°C, 3°C, or even 4–7°C becomes much less relevant for two fundamental reasons:

First, tipping points can initiate self-reinforcing feedbacks that continue driving change even after the original forcing changes.

Second, the impacts do not necessarily increase gradually with temperature. They can accelerate, compound, and cascade as interconnected systems begin to destabilize.

In other words, 1.5°C is not a destination. It is not merely a warning sign or an alarm. It is a tripwire.

A warning sign tells you that danger is ahead. An alarm tells you that danger may already be present. A tripwire is different: it marks a threshold at which crossing the line can trigger a chain of events that becomes increasingly difficult to control or reverse.

That is the critical distinction that can be lost when climate change is reduced to a single temperature number.

The real danger lies not in the number itself, but in what the Earth system is doing as we move beyond it.

We are not simply adding another fraction of a degree to a static planet. We are increasing the energy entering a dynamic, interconnected system—and that additional energy is altering the very processes that determine how the system responds.

The question, therefore, is not simply, “How many degrees warmer will Earth become?”

The more important question is:

“What happens as we cross the tripwires?”

1. The Ocean Holds Most of the Energy Imbalance

The ocean holds most of the excess energy accumulating in the climate system. A deep-ocean study has revealed that even the deepest layers of the ocean are warming at a measurable rate.

The oceans absorb and store more than 90% of the excess heat trapped by greenhouse gases. In 2025, a tiny increase—one-tenth of a degree—was observed. That seemingly insignificant change represents an enormous amount of additional stored thermal energy. This represents an amount of stored thermal energy roughly equivalent to a 2°C increase in the atmosphere and surface system.

If the accumulated ocean heat were distributed across land surfaces, it would equate to an estimated 35°C increase in land temperatures—a level that would make much of the planet uninhabitable.

This illustrates how the oceans have been masking the full extent of the Earth’s energy imbalance, acting as a temporary thermal buffer while simultaneously undergoing changes of their own, including increased stratification, circulation changes, and ecosystem disruption.

The entire Pacific Ocean is running approximately 1.6°C above its long-term average—roughly six standard deviations above the mean. In climate science, deviations of this magnitude are virtually off the charts, underscoring just how far outside what we would consider normal variability the climate system has moved.

2. Tipping Points Take Over the Coupling and Acceleration

Tipping points can fundamentally change how the climate system responds by coupling positive and negative feedbacks across multiple components of the Earth system.

The overriding concern for humanity should not simply be the average surface temperature. It should be how the millions of interconnected feedbacks within the climate system will respond.

We have a pretty good understanding of some of these feedbacks. For many others, we don’t.

One of the simplest examples is the albedo effect.

The physics of albedo is straightforward: bright, reflective surfaces send a portion of incoming solar energy back into space, while darker surfaces absorb more of it. Less ice means more exposed dark surfaces, more absorbed energy, and therefore more warming.

But the system quickly becomes much more complicated.

How does changing albedo affect cloud formation, particularly over the tropics? And what happens to the climate if those clouds increase—or decrease?

Low clouds are especially important because they can reflect substantial amounts of incoming sunlight back into space. If tropical low clouds diminish, the ocean could absorb significantly more solar energy, accelerating warming.

This is where the bleeding edge of climate science begins.

Clouds are arguably the largest remaining uncertainty in our understanding of climate sensitivity. They can reflect incoming solar radiation, producing a cooling effect, while high, thin clouds can allow incoming sunlight through while trapping outgoing heat.

Which effect dominates—and how that balance changes as the planet warms—is one of the great unanswered questions in climate science.

Our expectation is that the climate system could eventually approach a new equilibrium around +4°C above the preindustrial baseline, perhaps over the course of a couple of centuries. That would imply roughly +2–3°C this century, with additional warming continuing into the next.

The important point is that climate change is not a simple linear equation.

It is a massively interconnected system in which a change in one component can alter another, which then feeds back into the first.

Ice affects albedo. Albedo affects heating. Heating affects clouds. Clouds affect radiation. Radiation affects ocean temperatures. Ocean temperatures affect evaporation and atmospheric moisture. And the cycle continues.

Conclusion

What matters most for human habitability is not simply the temperature we measure at the surface. It is the amount of energy remaining in the climate system and how that energy is redistributed.

If the temperature “only” rises 2°C while energy accumulation continues, the surface temperature becomes much less informative by itself. What becomes increasingly urgent is how that additional energy—measured in joules—is redistributed to your location.

The most obvious example is the supercharged water cycle.

For every 1°C increase in temperature, air can hold approximately 7% more water vapor. The atmosphere doesn’t care about the global average temperature. Many places can experience temperatures 10°C above their local average. That creates the potential for dramatically greater atmospheric moisture and, consequently, more intense rain, hail, and snow events when that moisture is released.

And indeed, we are seeing extreme flood events occurring with increasing frequency, including events described as having return periods of hundreds of years. Hail has also become one of the largest sources of insurance claims affecting homes, automobiles, and agriculture.

While the long-term equilibrium matters, there is a much more immediate question.

What happens to you over the next five years?

We are already seeing rainfall becoming more intense and, in many places, more destructive—violent. A warmer atmosphere can hold more water vapor, increasing the potential for extreme precipitation. The question isn’t simply how hot the planet might become over the next 50 years.

The more immediate question is:

What is the violent rain going to do to your home, your community, your infrastructure, your insurance—and you—over the next five years?

That is where climate change stops being a distant projection and starts becoming a personal reality.

Welcome to the future. Climate change is accelerating—and the acceleration itself is accelerating.

As tipping points become increasingly coupled and reinforce one another, the amount of energy moving through the climate system is accelerating—and the rate of acceleration itself is increasing.

At this point, the question is no longer simply, “How many degrees warmer will the planet become?”

The more important questions are: How much additional energy are we going to continue trapping? Where is all that energy going? And what will it do when it gets there?

We are already beginning to see the answers—in floods, heatwaves, flash droughts, wildfires, hailstorms, extreme precipitation, and increasingly volatile swings between opposing extremes.

These are not separate problems.

They are different manifestations of an increasingly energized climate system.

The planet does not experience climate change as a number on a thermometer.

It experiences it as energy moving through the system.

And that energy has to go somewhere.

The climate system is being supercharged.

The question is no longer whether that energy will affect us.

The question is where it will hit—and what it will do when it gets there.

Postscript: Where Does All That Energy Go?

Q: I don’t quite understand part of the paper. What does a “35 degree increase” in temperature mean? Where I live, a summer day can be around 30 degrees Celsius. Would this mean a summer day at around 65 degrees? (30+35=65). Wouldn’t that be lethal?

A: Good question. The answer is yes—and no. That’s actually part of the point of the paper.

A 65°C temperature at your location would obviously be lethal. But the 35°C figure is an energy-equivalent thought experiment, not a prediction that your local summer temperature would simply go from 30°C to 65°C.

The bigger problem with using average temperatures is just that—they are averages. An average of 65°C across a large area could mean one location is 30°C, another is 40°C, and another is far beyond either. The distribution of that energy matters far more to human habitability than the average itself.

And that’s where I don’t expect all of the already stored energy to behave “on average.” I don’t know exactly how that energy will hit you. It could manifest as violent rainfall, hail, heatwaves, wildfires, flash droughts, or any number of other energy transfers we haven’t fully anticipated.

But as long as that energy remains trapped in the Earth system, it doesn’t simply disappear. It continues moving through the system and interacting with everything else. You cannot create or destroy energy—you can only experience its feedbacks.

And yes, we would have to adapt. If conditions outside became routinely lethal, people might increasingly move underground or into heavily climate-controlled environments to survive.

In any event, an average of 65°C would be pretty close to hell—whether you’re experiencing it alive or studying it after the fact. 😏

Where’s the Beef? Tariffs, Inflation, and the Climate Cost of Meat

Posted on 2026/08/21 by admin

On August 21, 2026, President Donald Trump announced a temporary 90-day waiver of out-of-quota tariffs on imported ground beef, allowing up to 300,000 metric tons to enter the U.S. market tariff-free in an effort to reduce grocery prices. The president said he had secured a commitment that the imported meat would be sold at 25% below current market prices, providing relief from persistent food inflation.

The move is intended to address a dramatic increase in the cost of ground beef, which has risen roughly 57% over the past five years. But the policy immediately drew backlash from domestic cattle ranchers and rural-state Republicans, including Senator Tim Sheehy, who warned that flooding the market with cheaper foreign beef could undermine American cattle producers.

There is another problem that may be even more important to consumers: much of the imported beef affected by the policy is frozen beef destined for commercial and restaurant use, rather than the fresh ground beef consumers typically purchase at the grocery store. That means the immediate impact on household grocery bills may be considerably smaller than the headline numbers suggest.

More importantly, the tariff waiver does little to address the underlying forces driving higher beef prices.

Climate Change Is Becoming an Inflation Problem

The cattle industry is increasingly exposed to the economic consequences of climate extremes. Drought, extreme heat, wildfires, water scarcity, degraded pasture, and volatile feed supplies all increase the cost of raising cattle. When these pressures become severe enough, ranchers may be forced to reduce their herds, further constraining beef supplies and pushing prices higher.

This creates a feedback loop. Climate extremes increase production costs and reduce the supply of cattle. Reduced supply raises beef prices. Higher prices then encourage producers to rebuild their herds, but rebuilding takes years. Another drought or extreme-weather event during that process can once again force herd reductions.

This is why simply importing cheaper beef may treat the symptom without addressing the disease.

The larger economic issue is what I call climate inflation: the gradual—and increasingly rapid—incorporation of climate-related costs into the prices of food, energy, insurance, housing, transportation, and other necessities.

For the past several years, inflation discussions have focused primarily on monetary policy, supply chains, labor costs, tariffs, and government spending. Those factors certainly matter. But climate-driven disruptions are becoming an increasingly important component of the cost structure of the economy.

And unlike a temporary tariff or a change in interest rates, climate pressures can compound over time.

The Beef Problem Is Bigger Than Beef

A 90-day tariff waiver may provide some temporary relief. It may even benefit restaurants and commercial food purchasers if imported frozen beef reaches the market at substantially lower prices.

But it does not create more water, restore drought-stricken grazing land, prevent wildfires, reduce extreme heat, or rebuild cattle herds that have been lost to climate-driven conditions.

Nor does it address the increasingly expensive insurance, infrastructure, agricultural, and supply-chain consequences of a changing climate.

If climate extremes continue to intensify, we should expect more of these conflicts. Policymakers will repeatedly face the same choice: temporarily suppress prices by opening markets to cheaper imports, or address the underlying conditions that are making domestic production increasingly expensive.

Where’s the beef?

It may increasingly be somewhere else.

And that is the larger warning. Climate change is no longer simply an environmental issue. It is becoming an economic variable—and climate inflation may prove to be one of the most consequential economic developments of the next decade.

The Bleeding Edge of Climate Change

While Sidd was in town, I took some notes. Somehow, they turned into this:

Climate Change: The Big Picture

There are many ways to look at climate change. From a micro perspective, there are millions of individual feedbacks operating throughout the Earth system. From a macro perspective, there is the climate system as a whole.

Understanding how those feedbacks interact—and, more importantly, how they feed back into one another—is at the bleeding edge of climate science.

One of the simplest examples is the albedo effect. The physics of ice is straightforward: bright, reflective ice sends a portion of incoming solar energy back into space, while darker ocean absorbs it. Less ice means more absorbed energy and, therefore, more warming.

But the system quickly becomes much more complicated.

How does changing albedo affect cloud formation, particularly over the tropics? And what happens to the climate if those clouds increase—or decrease?

The low clouds are especially important. They can reflect substantial amounts of incoming sunlight back into space. If tropical low clouds diminish, the ocean could absorb significantly more solar energy, accelerating warming.

This is where the bleeding edge begins.

Clouds are arguably the largest remaining uncertainty in our understanding of climate sensitivity. They can both reflect incoming solar radiation and trap outgoing heat. Which effect dominates—and how that balance changes as the planet warms—is one of the great questions in climate science.

My expectation is that the climate system could eventually approach a new equilibrium around +4°C above the preindustrial baseline, perhaps over the course of a couple centuries. That would imply roughly +2–3°C this century, with additional warming continuing into the next.

But that remains uncertain.

The important point is that climate change is not a simple linear equation. It is a massively interconnected system in which changes in one component can alter another, which then feeds back into the first. Ice affects albedo. Albedo affects heating. Heating affects clouds. Clouds affect radiation. Radiation affects ocean temperatures. Ocean temperatures affect evaporation and atmospheric moisture. And the cycle continues.

Everything is nonlinear.

Yet uncertainty about the exact trajectory does not mean uncertainty about what we should do.

The clearest lever we have is still the same: reduce CO₂ emissions and slow the accumulation of greenhouse gases in the atmosphere.

And while the long-term equilibrium matters, there is a much more immediate question.

What happens to you over the next five years?

The more immediate question is:

What is the violent rain going to do to your home, your community, your infrastructure, your insurance—and you—over the next five years?

That is where climate change stops being a distant projection and starts becoming a personal reality.

Climate Change
There are many ways to look at it. If you go with a micro view, there are millions of feedbacks. If you look at it from a macro view, there is the climate system.

How these feedbacks are feeding back is the bleeding edge of climate change.

One of the simplest of feedbacks, the Albedo effect, isn’t so simple. How much ice there is to reflect the energy is simple physics. But, how the clouds form over the tropics because of the Albedo effect is part of this bleeding edge. We don’t know if there are going to be more clouds over the tropics or viewer. The lower clouds are the ones of concern. If they disappear, then ocean heating will be accelerated.

In the big picture, clouds around the world are the biggest unknown. It is probable we will reach and level off around +4C over a couple centuries. Likely 2-3C this century and +4 the next.

But this is still unknown.
Clouds can reflect or absorb heat. It’s going to take a while until we know which is going to prevail. And, that is just one piece of the puzzle. Everything is so nonlinear it’s difficult. But, it’s clear what we have to do — reduce CO2.

Short term: the rain is getting so violent. It may get hotter over the next 50 years? More importantly what’s the rain going to do to YOU over the next 5 years?

Operation Blue Skies: Testing a New Way to Reduce Aviation’s Climate Impact

Posted on 2026/08/182026/08/18 by admin

by Daniel Brouse

Cloud feedback is one of the most important—and least understood—climate multipliers. That makes efforts to better understand and control aviation-related cloud formation particularly significant.

On August 18, 2026, the landmark £5 million “Operation Blue Skies” project was officially launched, marking the world’s first airspace-scale trial of contrail avoidance across an entire oceanic region.

The initiative targets the Shanwick Oceanic airspace in the eastern North Atlantic, one of the world’s busiest aviation corridors. The region is estimated to account for roughly 5% of global contrail warming.

Supported by the UK government and technology partners, the project will test whether relatively small operational changes—such as adjusting flight altitudes and routes to avoid atmospheric conditions conducive to persistent contrail formation—can significantly reduce aviation’s climate impact.

Contrails are more than short-lived streaks across the sky. Under cold, humid atmospheric conditions, aircraft exhaust can create ice crystals that persist and spread into cirrus clouds. These clouds can alter the Earth’s radiation balance by trapping outgoing heat, producing a warming effect that can substantially exceed the warming associated with the aircraft’s carbon dioxide emissions over short time scales.

The project is particularly important because contrails and their associated cloud effects remain among the largest uncertainties in assessing aviation’s total climate impact. Current estimates suggest that non-CO₂ effects, including contrails, account for roughly one-third of aviation’s overall climate impact.

Operation Blue Skies therefore represents more than an aviation experiment. It is a real-world test of whether targeted operational changes can interrupt a climate feedback with potentially significant consequences—without requiring new aircraft technology or eliminating flights.

If successful, the approach could provide a relatively inexpensive way to reduce aviation’s near-term warming contribution while researchers continue working to better understand the complex interactions among aircraft emissions, atmospheric moisture, clouds, and climate.

The significance extends beyond aviation. Climate change is increasingly revealing that the atmosphere is not simply a passive recipient of emissions. Feedbacks involving clouds, water vapor, ice, and atmospheric circulation can amplify or modify the initial forcing, sometimes producing effects far larger than the original disturbance.

Operation Blue Skies offers an opportunity to test whether understanding those feedbacks can translate directly into practical climate mitigation.

When Climate Moves the Crust: The Earth Quakes

Posted on 2026/08/172026/08/17 by admin

By Daniel Brouse and Sidd Mukherjee

For decades, we have studied the relationship between earthquakes and climate change. Early in that work, there was little evidence that changes in global temperature were having any meaningful effect on tectonic activity. That conclusion was reasonable at the time. Climate change was expected to progress relatively slowly, over centuries or even millennia, and the resulting changes in surface mass and hydrological conditions were correspondingly gradual.

That assumption no longer describes the world we are entering.

The rate of climate change has accelerated dramatically, and many of the associated physical changes are now occurring on timescales measured in decades, years, and—in some cases—even months. This does not mean that global warming is heating the Earth’s crust enough to expand tectonic plates and cause earthquakes. That effect remains negligible.

The more important mechanism is mass redistribution.

Climate change is rapidly moving enormous quantities of water and ice around the planet. Ice sheets are losing mass, glaciers are retreating, permafrost is thawing, groundwater is being depleted or redistributed, reservoirs and lakes are experiencing increasingly extreme fluctuations, and sea level is rising. These changes alter the loads imposed on Earth’s crust and, in some locations, the pressure and stress conditions surrounding faults.

Earthquakes are ultimately controlled by stress. A fault can remain locked for centuries while tectonic forces slowly accumulate until the stress exceeds the fault’s resistance to slip. Climate-driven changes in surface loading do not create the tectonic forces responsible for most earthquakes, but they can modulate the timing, location, and frequency of seismic events by nudging already-stressed faults closer to—or farther from—the point of failure.

That distinction is critical.

Climate change does not need to cause tectonic earthquakes to become a meaningful factor in seismic risk. It only needs to change the conditions under which faults fail.

Glacial Unloading

One of the clearest mechanisms is the loss of glacial and ice-sheet mass.

For thousands of years, enormous glaciers and ice sheets have imposed immense loads on the Earth’s crust. When that mass is removed, the crust responds through a process known as isostatic rebound. The underlying crust rises as the weight above it decreases, changing the distribution of stress within the lithosphere.

In regions undergoing rapid deglaciation, this unloading can alter stress on existing faults and increase seismic activity. The effect is particularly important because the removal of ice can continue for decades or centuries after the initial climatic warming.

The key point is simple: when climate change removes trillions of tons of mass from the surface, the crust responds.

Permafrost Thaw and Meltwater

The destabilization of frozen ground introduces another mechanism.

As permafrost thaws and glaciers retreat, meltwater can penetrate fractured rock and mountain systems. Increased fluid pressure within faults can reduce the effective normal stress holding the fault surfaces together. In simplified terms, water can make it easier for an already stressed fault to slip.

This does not mean that every episode of melting will produce an earthquake. Rather, it creates another pathway through which rapid environmental change can influence the mechanical conditions surrounding faults.

Where faults are already near failure, relatively small changes in fluid pressure can matter.

Hydrostatic Load Shifts

Climate change is also producing increasingly extreme changes in the distribution of surface water.

Severe droughts remove enormous quantities of water from reservoirs, lakes, soils, and groundwater systems. Extreme precipitation and monsoon events can then return massive amounts of water over remarkably short periods.

That changing weight alters the stresses imposed on the crust.

Large reservoirs have long been recognized as capable of inducing or modulating seismicity, particularly where water infiltration increases pore pressure along faults. Climate-driven swings in precipitation, drought, groundwater storage, snowpack, and reservoir levels can produce similar loading and unloading effects, although the magnitude and significance vary greatly by location.

The important issue is not simply how much water exists. It is where that water is, how rapidly it moves, and how that movement changes the stress field.

Sea-Level Rise

Sea-level rise represents another large-scale redistribution of mass.

As land-based ice melts, water that was previously stored on continents is transferred into the oceans. At the same time, the increasing weight of seawater changes the loading conditions along continental margins and beneath coastal regions.

These effects are generally small compared with the enormous tectonic forces responsible for earthquakes. Nevertheless, in regions containing faults already close to failure, even relatively small changes in stress can influence the timing of seismic events.

The scientific question, therefore, is not whether sea-level rise is going to cause earthquakes worldwide. It is whether rapid changes in ocean loading can measurably influence seismicity in susceptible regions.

The Planet Is Moving Water at an Extraordinary Scale

Perhaps the most remarkable evidence that this redistribution of mass is physically significant comes from Earth’s rotation itself.

When ice sheets lose mass, that water does not disappear. It is transferred from land—particularly from the high latitudes—into the global ocean. Over time, ocean circulation and gravity redistribute that water across the planet, with a substantial portion ultimately moving toward lower latitudes.

The quantity of water involved is so enormous that the redistribution is measurable in the Earth’s rotation.

The “Figure Skater” Effect

Earth is not a perfect sphere. Its rotation causes it to bulge slightly around the equator, making the planet an oblate spheroid.

The basic physics is familiar from a figure skater spinning on ice. When mass moves farther from the axis of rotation, the moment of inertia increases and the rate of rotation decreases. When mass moves toward the axis, the opposite occurs.

The redistribution of water caused by melting ice therefore changes Earth’s moment of inertia and slightly alters the length of the day.

This is not theoretical speculation. Modern geodesy can detect these changes.

Earth has lost well over 35 trillion tons (gigatonnes) of ice from its polar ice sheets and glaciers over the past few decades, with the resulting meltwater being redistributed through the global ocean system, ultimately increasing ocean mass at lower latitudes. That represents an extraordinary transfer of mass from the high-latitude continents toward the oceans and, through gravitational and rotational processes, toward the equatorial regions.

The mechanical consequence is the counterpart to isostatic rebound. Where ice loss removes an enormous surface load and allows the crust to rebound upward, the accumulation of additional ocean water places an increasing load on the seafloor and coastal crust. In effect, while the high latitudes are experiencing unloading, lower latitudes are experiencing climate-driven loading.

The magnitude of this redistribution is difficult to comprehend: tens of trillions of tons of mass are being transferred across the planet within a geologically instantaneous interval.

Climate change is therefore not merely changing atmospheric temperature. It is physically moving enormous quantities of matter across Earth’s surface—and the solid Earth responds mechanically to that redistribution.

From Temperature Change to Mass Redistribution

This is where the relationship between climate change and seismicity becomes more interesting.

The traditional question was:

Is a warmer atmosphere heating the crust enough to cause earthquakes?

The answer is essentially no.

The more important question is:

Is rapid climate-driven redistribution of ice, water, and surface mass capable of altering the stress and pressure conditions acting on faults that are already tectonically stressed?

The answer is yes, in principle—and in some settings, observations already demonstrate that environmental loading can modulate seismicity.

The magnitude of the effect varies enormously from one region to another. Tectonic forces remain overwhelmingly dominant, and climate-related loading should not be portrayed as a replacement for conventional earthquake science.

But that is precisely why the issue deserves attention.

A fault does not have to be pushed from a state of complete stability to failure by climate change. It may only require a small additional perturbation when it is already near its failure threshold.

As climate change accelerates, the frequency and magnitude of these environmental perturbations are changing as well.

The climate system is becoming a faster-moving component of Earth’s physical system. The question is no longer whether climate can interact with the solid Earth. It is how much, where, and how rapidly those interactions can alter seismic risk.

Demand Destruction: Bad News for the Economy, Good News for the Environment

Posted on 2026/08/14 by admin

U.S. retail sales fell unexpectedly by 0.6% month over month in July 2026, coming in well below the forecast of a 0.1% increase. The data, released this morning, points to a significant slowdown in American consumer spending and a reversal of the momentum seen in previous months.

Key Figures From the July Report

Headline retail sales: Down 0.6%, following a revised 0.2% increase in June.
Excluding autos: Down 0.3%, versus expectations for a 0.2% increase.
Excluding autos and gasoline: Down 0.2%, compared with an expected 0.3% increase.
Control group sales: Down 0.4%, missing the projected 0.3% gain.

Bad News for the Economy

The broad-based weakness suggests that American consumers are becoming increasingly constrained by high prices, elevated living costs, and strained household budgets. Discretionary spending appears to be particularly vulnerable as consumers cut back in response to declining purchasing power.

The slowdown is also affecting financial-market expectations, potentially strengthening the case for a more accommodative Federal Reserve monetary policy in the months ahead.

But there is another way to look at these numbers.

Demand Destruction

This may be another indication of demand destruction—a sustained reduction in consumption caused by rising prices, declining purchasing power, supply constraints, or the availability of alternatives.

Climate change can contribute to this process in several ways. Extreme heat, drought, flooding, wildfires, and other climate-related disruptions can damage agricultural production and supply chains, increasing the cost of food and other necessities. Rising insurance, energy, transportation, and infrastructure costs can further squeeze household budgets.

Food prices are particularly important. Climate-driven disruptions to agriculture can contribute to food inflation, creating one of the most direct ways climate change reaches the household budget. When essential goods become more expensive, consumers have less money available for discretionary purchases.

That creates an uncomfortable paradox.

Bad News for Consumers. Good News for the Climate?

For lower-income households, this is unquestionably bad news. Families already living close to the edge have far less ability to absorb higher food, housing, energy, transportation, and insurance costs. For them, demand destruction isn’t a lifestyle choice. It can mean doing without necessities or postponing purchases they would otherwise make.

But from an environmental perspective, declining consumption can have an unexpected benefit.

Our economy is built around a powerful cycle: produce more → sell more → consume more → produce even more. Economic growth has traditionally depended heavily on increasing consumption of energy, materials, goods, and services.

If rising costs begin breaking that cycle, the result could be a gradual decline in resource consumption.

That is the paradox of demand destruction:

What is bad news for the economy can sometimes be good news for the environment.

A reduction in fossil-fuel consumption, material throughput, unnecessary production, and resource-intensive consumption can reduce environmental pressures. In that sense, demand destruction could unintentionally contribute to the transition away from an economic model based on ever-increasing consumption.

The problem is that we should not confuse economic hardship with a successful environmental transition.

There is a profound difference between people consuming less because they have chosen more efficient, sustainable alternatives and people consuming less because they can no longer afford what they need.

The first represents managed transition.

The second represents contraction.

The challenge is to find a way to reduce humanity’s environmental footprint without forcing the people least able to absorb the costs to bear the greatest burden.

That may ultimately be one of the defining economic challenges of climate change: how do we move beyond consumerism without making poverty the mechanism that gets us there?

Money Moves People: Why Demand Destruction May Be the Fastest Path Beyond Fossil Fuels

Posted on 2026/08/132026/08/13 by admin

by Daniel Brouse

2026: The New Economic Reality

Money moves people.

The climate costs of fossil-fuel dependence are increasingly outweighing its benefits—not in some distant future, but here and now. We are moving beyond arguments about what climate change might cost decades from today. Across the Western world, climate impacts are already imposing costs of hundreds of billions of dollars in real time.

Insurance is only one part of the story.

Infrastructure, agriculture, transportation, labor productivity, public health, energy systems, and financial markets are all beginning to absorb the cost of a destabilizing climate. The economic question is therefore changing. It is no longer simply:

“What will climate change cost us?”

It is increasingly:

“How much are we willing to pay to preserve an energy system that is becoming progressively more expensive to maintain?”

Climate Stress Is Becoming an Economic Stress Test

The physical infrastructure of the global economy is already being affected.

Maersk CEO Vincent Clerc has warned that climate change is putting increasing pressure on European waterways and that substantial infrastructure investment will be needed to keep the Rhine operating as a critical transportation artery.

But the economic importance of waterways extends far beyond shipping.

Rivers, lakes, and reservoirs are also critical components of the energy, industrial, agricultural, municipal, and ecological systems that support modern economies.

When water levels fall or water temperatures rise, power plants can be affected directly. Thermoelectric and nuclear power plants rely heavily on water for cooling. If river flows become too low, or water temperatures become too high, operators may be forced to reduce generation or temporarily shut down units because sufficient cooling capacity is no longer available or because thermal discharge limits are exceeded.

That creates an economic chain reaction:

Lower river flows or higher water temperatures
↓
Reduced cooling capacity
↓
Reduced power generation
↓
Tighter electricity supplies
↓
Higher electricity prices and grid stress
↓
Higher operating costs for industry and consumers

The same waterways that transport fuel, raw materials, agricultural products, chemicals, and manufactured goods can therefore also be essential to producing the electricity needed to move and manufacture those goods.

Water is simultaneously a transportation system, cooling system, industrial input, agricultural resource, and ecological asset.

When that system becomes unstable, multiple economic sectors can be affected at the same time.

Low water levels can also restrict the movement of coal, oil, natural gas, grain, chemicals, construction materials, and other bulk commodities. Barges may have to reduce their loads or make more trips to transport the same volume of goods. In some cases, alternative transportation by rail or truck becomes necessary, increasing fuel consumption, congestion, labor costs, and emissions.

Flooding creates the opposite problem.

Excess water can damage ports, locks, bridges, rail connections, roads, warehouses, industrial facilities, and electrical infrastructure. A waterway can therefore become economically disruptive at both extremes—too little water and too much water.

Agriculture is similarly exposed. Rivers and reservoirs provide irrigation, livestock water, and municipal supplies. Persistent drought can reduce agricultural output while increasing competition among farmers, cities, industry, ecosystems, and energy producers for increasingly scarce water.

There is also a less visible economic cost: water temperature itself is becoming an economic variable.

Warmer rivers can reduce their ability to absorb additional heat from industrial processes and power-plant cooling systems. At the same time, warmer water can stress aquatic ecosystems, fisheries, and drinking-water systems, creating additional regulatory, treatment, and ecological costs.

This produces a broader economic concept that is often missed in conventional disaster accounting:

Waterway disruption is not a single-sector problem. It is a systems problem.

The Rhine and Danube are not simply waterways. They are components of Europe’s economic infrastructure. They connect ports, factories, power plants, farms, cities, mines, warehouses, rail networks, and consumers. When climate conditions interfere with their operation, the economic consequences propagate through the system. A river does not have to disappear to create an economic crisis. It only has to become less reliable. And reliability is one of the most valuable—and often least visible—assets in a modern economy.

The Economic Toll of Extreme Weather

Global extreme weather and natural disasters are generating enormous economic losses. Recent estimates from the International Chamber of Commerce, insurers including Swiss Re, and disaster-loss tracking organizations show that severe convective storms, wildfires, floods, and other extreme events are producing annual losses measured in the hundreds of billions of dollars.

The first half of 2026 alone has already produced approximately $100 billion in global economic losses, while the cumulative economic toll over the past decade has reached roughly $2 trillion, according to recent assessments.

And the year is not over.

The second half of the year normally includes the peak of the North Atlantic hurricane season, creating the potential for another substantial wave of losses.

The Major Economic Drivers

Escalating annual losses.
Global disaster losses continue to accumulate at extraordinary levels. The combined economic losses from 2022 and 2023 alone have been estimated at roughly $451 billion.

The concentration of U.S. losses.
The United States remains a major source of global insured catastrophe losses. By June 2026, the country had already experienced 12 billion-dollar weather and climate disasters, with estimated losses totaling approximately $31.9 billion.

Severe convective storms.
Hail, tornadoes, straight-line winds, and other severe thunderstorms have become an increasingly persistent source of financial losses. The United States recorded a record 21 billion-dollar severe-convective-storm events in 2025.

Extreme heat and productivity.
The economic damage from climate change is not limited to destroyed buildings and infrastructure. Heat reduces worker productivity, particularly in construction, agriculture, manufacturing, and outdoor occupations. Global heat-related productivity losses have been estimated at roughly 1% of world GDP annually—around $1 trillion.

The long-term U.S. bill.
U.S. billion-dollar weather and climate disasters have generated cumulative damages exceeding $3 trillion since systematic tracking began in 1980.

The Trajectory Is the Story

Recent U.S. disaster statistics illustrate the increasing economic burden:

Year	Billion-Dollar Events	Estimated Damage	Major Loss Drivers
2025	23	~$115 billion	Severe storms, wildfires
2024	27	~$182.7 billion	Severe storms, tropical cyclones, extreme heat
2023	28	$145+ billion	Severe storms and other extreme events

The important point is not that every individual disaster can be attributed exclusively to climate change.

The economic signal emerges from the frequency, intensity, persistence, and cumulative cost of extreme conditions.

Climate change does not need to create every storm, flood, drought, or wildfire to transform the economics of risk. It only needs to increase the probability, severity, or duration of damaging events enough to alter the cost structure of society.

That is already happening.

“Demand Destruction” Is Our Friend

This brings us to one of the most powerful—and least appreciated—economic mechanisms in the energy transition:

Demand destruction.

The International Energy Agency has projected that global oil demand will decline more sharply than previously expected in 2026, forecasting a reduction of approximately 1.6 million barrels per day.

The significance extends beyond the number itself.

As an economist, I am less concerned with establishing a specific date by which the world must eliminate fossil fuels than I am with changing the economic forces that sustain fossil-fuel demand.

That distinction matters.

People do not necessarily change because someone wins an argument about climate science. They change because incentives change. Prices change. Risk changes. Availability changes. And eventually, behavior changes.

Money Moves People

I am unlikely to change the minds of the roughly 20% of Americans who are ideologically committed to policies that accelerate fossil-fuel dependence.

But that leaves the vast majority of the population. And economics can do much of the work. Integrated Climate Stewardship begins with reducing unnecessary consumption.

Consumerism drives energy demand, resource extraction, pollution, waste, and habitat destruction. Every unnecessary unit of consumption represents another demand for energy and materials somewhere in the global economy.

Consume less, and demand falls.

Demand falls, and the economic incentive to produce falls.

That is the mechanism.

The Economics of Personal Climate Stewardship

Today, only a small fraction of Americans appear to be pursuing a deliberately structured net-zero lifestyle through continuous behavioral reductions, efficiency improvements, and intentional balancing. But this does not mean the model cannot scale. The critical question is how climate stewardship is presented.

If reducing climate impact is framed exclusively as sacrifice, people resist. If it is framed as economic self-interest, the equation changes.

What happens when people discover that reducing unnecessary consumption can save them thousands of dollars a year?

What happens when energy efficiency lowers household expenses?

When smaller vehicles reduce fuel, maintenance, and insurance costs?

When reducing waste means buying fewer things that do not provide meaningful value?

When local production and durable goods become economically attractive?

When conservation becomes synonymous with financial resilience?

The behavior does not have to begin with ideology.

It can begin with a household budget.

Vote With Your Dollars

This is where the remaining majority of the population becomes economically important.

When millions of people begin making purchasing decisions based on cost, durability, efficiency, resilience, and environmental impact, they collectively alter demand.

When demand changes, markets respond. When fossil-fuel demand declines, the economic incentive to extract, refine, transport, and sell fossil fuels declines with it. This is fundamentally different from waiting for governments to impose every change from the top down. It is a bottom-up economic transition.

People do not have to agree about everything.

They do not have to become climate activists.

They do not even have to agree about climate policy.

They simply have to discover that some forms of consumption are no longer worth what they cost.

The Feedback Loop

The process can become self-reinforcing:

Lower unnecessary consumption
↓
Lower household costs
↓
Lower energy and resource demand
↓
Reduced fossil-fuel demand
↓
Lower economic incentive for fossil-fuel expansion
↓
Greater investment in alternatives and efficiency
↓
Further reductions in fossil-fuel demand

This is an economic feedback loop.

And unlike many climate-policy debates, it does not require everyone to agree on the destination before beginning the journey.

Demand Destruction Is the Transition

The transition away from fossil fuels is often described as a supply problem:

How quickly can we replace coal, oil, and natural gas?

But there is another side of the equation.

How quickly can we reduce the demand that makes fossil-fuel extraction profitable?

That may ultimately be the more powerful question.

We do not need to convince every person to become an environmentalist.

We need to make lower-carbon choices increasingly rational economic choices.

The climate crisis is already generating enormous costs. Insurance premiums are rising. Infrastructure is being stressed. Agricultural productivity is being disrupted. Heat is reducing labor capacity. Extreme weather is destroying capital. Supply chains are becoming more vulnerable.

These costs are not theoretical.

They are appearing on balance sheets, household budgets, insurance statements, government budgets, and corporate earnings reports.

The economic system is beginning to receive the bill.

And money moves people.

Demand destruction is not the enemy of the energy transition.

Demand destruction is the transition.

A poem by Daverick Leggett

Every day I walk a hundred years
to the hill where my great, great granddaughter sits.
I carry words of blessing
and reach to touch her back.

But feeling me near she turns,
sad-eyed and heavy with grief.

“What was it like?” she asks,
“when the great whales swam,
when the birds sang you awake,
when the rains came soft,
and the soil smelled sweet underfoot?”

And the blessings
catch in my throat.

On darker days she turns,
her famished face charred, and eyes
sunk in their bony orbits,
burn with curses.

And the blessings
froth at my mouth
with the poisonous
spume of betrayal.

On the darkest of all days
I walk the hundred years
and find no one there.

Let today be the bright day.
Let today be the bright day
I lay my hand upon her back.

And, feeling me near, she turns
and blesses me, saying,

“Your love was fierce enough,
sweet ancestor,
your love was fierce enough.”

The Good Ancestor and the Climate System: Applying Long-Term Thinking to a Nonlinear Climate Future

Posted on 2026/08/13 by admin

by Daniel Brouse

Introduction

Roman Krznaric’s The Good Ancestor: How to Think Long Term in a Short-Term World begins with a deceptively simple question: How can we become good ancestors? His argument is fundamentally about time. Modern societies have become increasingly organized around immediate rewards, quarterly results, election cycles, daily news, and rapidly changing information. The climate system operates on radically different temporal scales. Carbon dioxide released today can influence atmospheric and oceanic processes for decades to centuries, while ice sheets, ocean circulation, ecosystems, and human infrastructure respond through interacting processes that unfold across multiple time horizons.

This temporal mismatch is one of the central problems in understanding climate change.

The climate problem is therefore not merely a problem of atmospheric physics. It is also a problem of human time perception. We make decisions within political, economic, and personal time horizons while the Earth system accumulates energy, reorganizes circulation, alters hydrological patterns, loses ice, and modifies ecological and social conditions over much longer periods.

Krznaric identifies six approaches to long-term thinking: deep-time humility, legacy mindset, intergenerational justice, cathedral thinking, holistic forecasting, and transcendent goal.

Applied to climate science, these six principles provide more than an ethical framework. They provide a conceptual architecture for understanding why conventional climate decision-making repeatedly underestimates systemic risk.

My climate work has focused on a related problem: climate change is not adequately described as a linear increase in average temperature followed by proportionally increasing impacts. The climate system is a coupled, nonlinear system in which accumulated energy can alter the conditions governing subsequent change. Ocean heat, atmospheric moisture, sea-level rise, ice loss, circulation changes, extreme heat, ecological degradation, and socioeconomic disruption interact across different timescales.

The result is a fundamental challenge to short-term thinking.

We are attempting to manage a long-duration, nonlinear Earth-system transition with institutions designed to optimize the present.

Krznaric’s Good Ancestor framework provides a powerful way to confront that contradiction.

1. Deep-Time Humility: Recognizing the Scale of the System

Krznaric’s first principle is deep-time humility: understanding humanity’s extraordinarily small position within the history of Earth and the cosmos. His argument is that recognizing our temporal insignificance can expand rather than diminish our sense of responsibility.

Climate science makes this principle especially important.

Human political systems commonly operate within horizons of months, years, or decades. Climate processes operate simultaneously across days, years, decades, centuries, and longer. An extreme heat event can develop within hours. Ocean heat accumulation occurs over years and decades. Ice-sheet responses can extend over centuries. Carbon-cycle consequences can persist much longer.

These are not competing descriptions of the same phenomenon. They are different temporal layers of one coupled system.

That distinction matters because a climate system can appear relatively stable when observed over one interval while undergoing substantial structural change over another.

A single year’s temperature anomaly tells us something important about the state of the system. But it does not necessarily reveal the direction of the system’s underlying dynamics.

This is why rates of change and changes in rates of change matter.

A climate variable that is increasing linearly presents one kind of risk. A variable whose rate of increase is itself changing presents another. If the acceleration persists, projections based solely on historical averages can systematically underestimate the future trajectory.

The same principle applies to sea-level rise, ocean heat, extreme heat, ice loss, and other indicators. The important question is not simply:

How much has the climate changed?

It is also:

How rapidly is the rate of change itself changing?

This perspective is consistent with the central premise of a nonlinear climate framework: the Earth system must be evaluated not merely by its current state, but by its trajectory, acceleration, feedback structure, and proximity to thresholds.

Deep-time humility therefore changes the unit of analysis.

We stop asking only what climate conditions will look like at the end of the next political cycle and begin asking what trajectory we are establishing for people living decades, centuries, and generations from now.

2. Legacy Mindset: The Climate We Leave Behind

Krznaric’s second principle is the legacy mindset: asking how future generations will remember what we did with the conditions inherited by our generation.

This is particularly powerful when applied to climate change because humanity is not merely experiencing a changing climate.

We are actively determining the initial conditions inherited by future generations.

Every generation receives an Earth system shaped by previous generations and then modifies it before passing it forward.

The critical question becomes:

What climate system are we leaving behind?

That question is larger than carbon emissions alone.

We are leaving future generations altered coastlines, changed hydrological regimes, warmer oceans, different ecosystems, stressed agricultural systems, modified atmospheric circulation, altered wildfire regimes, infrastructure designed for historical climate conditions, and potentially reduced resilience to compound extremes.

The legacy is therefore a system state, not simply an emissions total.

This distinction is important to a nonlinear framework. The consequences of present decisions are not necessarily proportional to the decisions themselves. A system approaching a threshold can respond very differently from one far from a threshold.

The legacy mindset consequently requires us to evaluate not merely the emissions we produce but the conditions under which future generations will have to operate.

That changes the moral question from:

How much climate damage can we tolerate?

to:

What state of the Earth system are we willing to hand to people who had no role in creating it?

That is a substantially different standard.

3. Intergenerational Justice: Future People Are Stakeholders

The third principle, intergenerational justice, asks us to recognize obligations to people who do not yet exist. Krznaric explicitly connects this concept to thinking about the seventh generation and the rights and interests of future people.

Climate change exposes a fundamental weakness in conventional economic and political accounting: the people who receive many of the costs may not be the people making the decisions that generate them.

A decision made today can produce benefits immediately while distributing costs across decades.

That creates a profound temporal asymmetry.

The beneficiaries are present.

The consequences may be inherited.

This becomes even more consequential when nonlinear processes are involved. A generation may consume the benefits of an activity while transferring to future generations a climate system with fewer degrees of freedom and less resilience.

This is the point at which climate science and climate ethics converge.

If the system is approaching thresholds, then delaying action does not simply preserve the same problem for later. It can change the problem itself.

The future may inherit not merely more warming, but a different set of system dynamics.

That distinction is central.

A linear interpretation imagines:

more emissions → proportionally more warming → proportionally more impacts.

A nonlinear systems interpretation recognizes the possibility of:

forcing → warming → feedback amplification → system reorganization → threshold crossing → cascading consequences.

The precise behavior of each component must be established scientifically; not every proposed feedback or tipping interaction is equally certain. But the broader systems principle is robust: interacting components can produce outcomes that are not adequately represented by treating each component independently.

Intergenerational justice therefore demands more than reducing today’s visible damage.

It requires maintaining future adaptive capacity.

4. Cathedral Thinking: Building What We Will Never See Completed

Krznaric’s fourth principle is cathedral thinking: beginning projects whose completion or full benefits extend beyond an individual lifetime. He uses the cathedral as a metaphor for undertaking work whose builders understand that they may never see the finished structure.

This concept fits climate science almost perfectly.

Climate stabilization, ecosystem restoration, adaptation of infrastructure, long-term water management, coastal planning, soil restoration, forest management, energy transformation, and preservation of scientific observations all require decisions whose full consequences extend beyond ordinary political cycles.

But cathedral thinking must go beyond simply building large projects.

It requires building institutional continuity.

A climate strategy designed for four years is not a long-term climate strategy. Neither is one designed around a single election, market cycle, administration, or corporate planning horizon.

The climate system does not reset when political leadership changes.

A genuine cathedral approach would therefore establish institutions capable of maintaining long-term climate observation, infrastructure adaptation, ecosystem protection, scientific research, and risk management regardless of short-term political fluctuations.

This also changes the purpose of climate modeling.

A model should not merely tell us what conditions are likely at a particular future date. It should help identify path dependencies—decisions made today that constrain what future generations can realistically do.

That is especially important when dealing with tipping elements.

If Greenland ice loss, West Antarctic ice instability, permafrost degradation, Amazon ecosystem stress, ocean circulation changes, or other components approach thresholds, the relevant question is not simply whether a particular threshold will be crossed at a particular date.

The more important question is:

Are we constructing conditions that make future reversibility increasingly difficult?

Cathedral thinking therefore demands that we evaluate irreversibility and option value.

A decision that preserves future options has value even if its immediate economic return is difficult to quantify.

5. Holistic Forecasting: From Isolated Variables to a Coupled System

The fifth principle, holistic forecasting, may be the most directly compatible with a nonlinear climate framework.

Krznaric argues that long-term forecasting must consider multiple pathways for civilization rather than rely upon narrow forecasts of a single future.

Climate science requires precisely this kind of thinking.

The Earth system is not a collection of independent variables.

Atmospheric warming influences atmospheric moisture. Increased moisture changes latent heat transport and precipitation dynamics. Ocean warming alters marine heatwaves, circulation, and sea-level contributions. Ice loss modifies albedo and freshwater fluxes. Atmospheric and oceanic circulation redistribute energy. Ecosystem degradation changes carbon storage and surface energy exchange. Extreme events impose stress on infrastructure, agriculture, insurance systems, financial markets, and public health.

These processes can interact.

A useful conceptual chain is therefore not:

CO₂ → temperature → damage.

It is closer to:

forcing → energy accumulation → physical response → feedback → circulation and ecological response → extreme events → infrastructure and economic stress → societal response → additional environmental feedbacks.

This is where the concept of nonlinear acceleration becomes important.

The climate system may exhibit changes in the rate of change because feedbacks alter the system’s effective response over time.

A useful research framework therefore needs to monitor at least four dimensions:

State — where the system is.
Velocity — how rapidly it is changing.
Acceleration — whether that rate is changing.
Coupling — whether independent indicators are becoming dynamically connected.

The fourth dimension is particularly important.

A collection of extreme indicators becomes much more consequential when they cease behaving as isolated anomalies and begin interacting as components of a broader system transition.

This is why the emphasis on persistent nighttime heat, ocean heat accumulation, sea-level acceleration, hydrological disruption, and tipping-system interactions is important.

The question is no longer simply whether one record has been broken.

It is:

Are multiple components of the climate system changing simultaneously in ways that reinforce one another?

That is a holistic forecasting question.

6. Transcendent Goal: From Climate Management to System Preservation

Krznaric’s sixth principle is the transcendent goal—a purpose larger than short-term institutional interests. His formulation points toward the goal of creating conditions in which humanity and the living world can thrive over the long term.

Climate policy frequently becomes trapped in narrower objectives:

reducing emissions by a certain percentage;
achieving a particular temperature target;
meeting a regulatory deadline;
protecting a particular industry;
minimizing near-term costs.

These objectives are useful, but they can become inadequate when treated as the ultimate goal.

The deeper objective should be preserving a functioning Earth system capable of supporting human civilization and ecological complexity across generations.

That means climate policy should ultimately be judged by resilience rather than by any single metric.

The goal is not merely to minimize today’s inconvenience.

It is to preserve the capacity of future generations to choose their own future.

That is a transcendent objective because it places human civilization within the larger Earth system rather than treating the environment as an externality.

The Six Principles as a Climate Research Architecture

Krznaric’s six principles can therefore be transformed from philosophical concepts into an analytical framework for climate research:

Krznaric principle	Climate application
Deep-Time Humility	Analyze climate trajectories across decades, centuries, and longer system timescales
Legacy Mindset	Measure the Earth-system conditions inherited by future generations
Intergenerational Justice	Treat future adaptive capacity as an ethical and analytical constraint
Cathedral Thinking	Design climate institutions, infrastructure, and restoration projects beyond political cycles
Holistic Forecasting	Model coupled physical, ecological, economic, and social pathways rather than isolated variables
Transcendent Goal	Preserve a resilient Earth system and the long-term capacity of civilization to thrive

Together, these principles produce something more powerful than a philosophical appeal to “think long term.”

They provide a temporal systems framework.

From Climate Change to Climate Regime Change

This framework also helps explain why the distinction between climate change and climate regime change matters.

Climate change can be understood as a shift in the statistical characteristics of the climate system.

Climate regime change goes further.

It asks whether the underlying relationships among components of the system are themselves changing.

A regime transition could manifest as persistent changes in extreme heat, nighttime temperatures, precipitation behavior, ocean heat, sea-level rise, circulation patterns, ecological responses, or the frequency and persistence of compound extremes.

The importance of persistent nighttime heat illustrates this distinction.

A daytime temperature record is an extreme event.

Persistent elevation of nighttime temperatures is different because the nighttime period normally provides an opportunity for ecosystems, infrastructure, agriculture, and human bodies to dissipate accumulated heat.

When nighttime cooling is progressively compressed, heat accumulates across successive days.

The system is no longer simply producing isolated extremes.

The baseline itself is moving.

This is precisely where the Good Ancestor framework becomes useful.

A short-term observer asks:

Was today unusually hot?

A long-term systems observer asks:

Has the system entered a state in which unusually hot conditions are becoming persistent, self-reinforcing, and structurally normal?

Those are fundamentally different questions.

The Climate Problem as a Failure of Temporal Governance

Krznaric describes modern society as being dominated by what he calls the “tyranny of the now”: the tendency to privilege immediate concerns over long-term consequences.

Climate change exposes this problem with unusual clarity.

Political systems are optimized around elections.

Businesses are often optimized around quarterly or annual performance.

Financial systems discount future returns.

News systems reward immediacy.

Social media rewards attention measured in seconds.

The climate system does not operate according to any of these clocks.

This produces a structural mismatch:

Human institutions optimize for the present while the Earth system integrates the past and determines the future.

That mismatch is one reason climate risks can repeatedly be underestimated.

A society may respond to an extreme event after it occurs while failing to recognize that the event is part of a changing distribution.

It may repair infrastructure to the historical climate standard even while the climate distribution is shifting.

It may calculate the immediate cost of mitigation while ignoring the potentially much larger cost of reduced future resilience.

And it may treat each extreme as an independent disaster rather than examining whether multiple extremes are manifestations of a common systemic transition.

Good Ancestor thinking challenges this institutional short-termism directly.

Toward a Good Ancestor Climate Index

The philosophical framework suggests a possible extension of climate-risk measurement.

Instead of evaluating climate policy solely through emissions, temperature, or economic cost, a Good Ancestor Climate framework could ask whether present decisions increase or decrease the resilience inherited by future generations.

Such an assessment could consider:

Physical trajectory:
Are major climate indicators accelerating, stabilizing, or decelerating?

Feedback exposure:
Are positive feedbacks becoming stronger or more interconnected?

Threshold proximity:
Are critical Earth-system components moving toward states where reversibility becomes increasingly difficult?

Persistence:
Are extreme conditions becoming more persistent rather than merely more intense?

System coupling:
Are climate, ecological, infrastructure, economic, and social stresses becoming increasingly interconnected?

Adaptive capacity:
Are we expanding or consuming the ability of future generations to respond?

Intergenerational burden:
Are present benefits being purchased by transferring disproportionate costs into the future?

This would shift climate assessment from a narrow accounting of emissions toward a broader accounting of system inheritance.

The central metric becomes:

What are we leaving behind?

The Good Ancestor Test

Krznaric’s philosophy ultimately suggests a remarkably simple test for climate decisions.

Before making a decision, ask:

Would the people living with its consequences a century from now regard us as responsible ancestors?

That question can be applied to virtually every major climate decision.

Would future generations regard us as good ancestors if we knew that climate indicators were accelerating and chose to treat them as static?

Would they regard us as good ancestors if we knew that physical systems were becoming increasingly coupled but continued to govern them separately?

Would they regard us as good ancestors if we optimized infrastructure for a climate that no longer exists?

Would they regard us as good ancestors if we transferred enormous adaptation costs to people who had no voice in the decisions that created them?

And perhaps most importantly:

Would they regard us as good ancestors if we possessed evidence of an approaching systemic transition but refused to think beyond the next election, fiscal year, or news cycle?

These questions transform climate change from an abstract environmental problem into a question of historical responsibility.

Conclusion

Roman Krznaric’s The Good Ancestor provides an ethical and philosophical framework for confronting one of the greatest weaknesses in modern climate governance: our inability to think on the same temporal scale as the system we are changing.

His six principles—deep-time humility, legacy mindset, intergenerational justice, cathedral thinking, holistic forecasting, and transcendent goal—can be mapped directly onto the requirements of nonlinear climate analysis.

Deep-time humility expands the temporal horizon.

Legacy mindset forces us to consider the Earth system we leave behind.

Intergenerational justice recognizes future people as legitimate stakeholders.

Cathedral thinking requires projects and institutions that outlast their creators.

Holistic forecasting demands that climate risks be evaluated as coupled systems rather than isolated variables.

And the transcendent goal establishes a purpose larger than immediate economic or political interests: maintaining a resilient Earth system capable of sustaining future generations.

This perspective reinforces a central proposition of nonlinear climate research:

The most important climate signal may not be the magnitude of change at a particular moment, but the changing dynamics of the system itself.

If rates of change increase, if feedbacks strengthen, if extremes become persistent, if previously separate components become coupled, and if thresholds become increasingly consequential, then the climate problem is no longer adequately described as a gradual environmental trend.

It becomes a system transition.

And once the problem is understood as a system transition, the moral question becomes unavoidable.

We are not merely deciding what kind of climate we will experience.

We are deciding what kind of Earth system we will hand to those who come after us.

That is the essence of the Good Ancestor principle.

The test of our generation will not ultimately be whether we correctly predicted every detail of the future.

It will be whether, having recognized the direction and dynamics of the system, we acted as though future generations mattered.

In that sense, becoming a good ancestor is not an exercise in nostalgia or moral sentiment.

It is a demand for better temporal mathematics, better systems thinking, better governance, and better stewardship.

The future is not simply something that happens to us.

We are its ancestors already.
