Research on advanced illness, extreme weather and system justification helps explain the strangest political pattern of our time: the worse the climate gets, the faster leaders retreat.
In late June 2026, Europe endured one of the most extreme heatwaves in its recorded history. Poland set an all-time national temperature record of 40.5°C, while France reached 44.3°C and recorded its hottest day since nationwide measurements began. The human toll was far greater than early reports suggested. A World Health Organization assessment later identified more than 14,000 excess deaths during the two-week peak alone. World Weather Attribution concluded that heat of this severity would have been virtually impossible without human-caused climate change.
You would expect that kind of summer to accelerate climate policy. It did the opposite.
In my recent analysis of climate policy reversals, I documented 45 major rollbacks across 15 jurisdictions in a single year, the full list public, from the rescinded EPA Endangerment Finding in the United States to a weakened EU carbon market and new North Sea oil approvals in the UK. Six of those reversals happened within five weeks, at the very moment heatwaves were killing people across Europe.
Almost none of the governments involved dispute the science. They accept the diagnosis. What they increasingly reject is the treatment. The treatment, to be clear, is not any single policy; reasonable people disagree about instruments and pace. It is the willingness to adopt measures proportionate to the diagnosis. The difference between disagreement and denial shows in behavior: disagreement rejects a policy and proposes another one of comparable scale. Denial rejects every policy and proposes nothing. To understand why that willingness is collapsing, you have to look somewhere climate commentary rarely goes: at what psychology and medicine know about how people handle knowledge they can’t bear.
What Medicine Teaches Us About Unbearable Truths
Medicine has studied this for decades. A systematic review of studies on advanced and terminally ill cancer patients found that only about half accurately understand their own prognosis. That figure alone does not prove denial. Patients misjudge their prognosis for many reasons, including cautious communication from doctors, genuine medical uncertainty, and the simple fact that hope and understanding can coexist.
But within that gap, denial plays a documented role. A review in Cancer Management and Research describes denial as a response that “can serve as a defense mechanism when confronted with information that is too distressing to be processed right away.” In the short term, this protects the psyche, and newly diagnosed patients who pass through a denial phase often show no elevated anxiety or depression. The problem is persistence: in late-stage illness, the same review finds, denial becomes “one of the main barriers to referral to palliative care.” The mechanism that once protected the patient now prevents action while action still matters.
The most instructive case for climate politics is not the patient who rejects the diagnosis. It is the smoker who accepts it fully, and keeps smoking. Climate politics in 2026 is full of smokers: governments that accept every word of the science and approve the next oil field.
The Denial That Matters Is Not About Science
The sociologist Stanley Cohen, in his classic States of Denial, distinguished three forms of denial: literal denial (“it isn’t happening”), interpretive denial (“it’s happening, but it’s not what you think”), and implicatory denial, which accepts the facts while denying what they demand of us.
Combine Cohen’s typology with newer research on climate delay, and the modern retreat from reality unfolds in four recognizable stages:
- Deny the diagnosis. “It isn’t happening, or humans aren’t causing it.” The classic form, now a shrinking minority position in most Western publics.
- Deny the cause. “The disaster is real, but climate change had nothing to do with it.” The floods were cloud seeding; the fires were arson; the heat is just summer.
- Deny the treatment. “The science is right, but this particular policy is too expensive, too fast, unfair or ineffective.” Every policy, every time.
- Deny the responsibility. “Action matters, but someone else must go first.” China, consumers, industry, the next government.
Each stage concedes more of the science while protecting the same outcome: inaction. And this summer supplied the sequence’s logical endpoint. One of the most discussed climate op-eds of the season, published in The Telegraph in July, disputed no science at all. It declared the war against climate change lost, argued Britain cannot stop warming alone, and concluded net zero should be scrapped. Stages three and four in a single column, capped with the newest escape route: surrender. Climate scientist Michael Mann has long warned about this “doomism,” and it belongs in the same family, because a lost war, like a hoax, requires nothing of anyone. It converts a difficult coordination problem into an argument for surrender. In the United States and much of Europe, literal denial is no longer the dominant form, nor the most politically useful one. The Yale Program on Climate Change Communication reported in late 2025 that the “Alarmed” segment of the American public has grown from 11% to 25% in a decade, while 11% remain “Dismissive.” Organized literal denial retains real influence, but the center of gravity has moved.
What increasingly shapes climate politics instead is implicatory denial. The sociologist Kari Norgaard, who spent a year embedded in a Norwegian community for her book Living in Denial, found that people who fully accepted climate science still organized their daily lives, conversations and politics as if it were not true. Not because they lacked information, but because the implications felt too heavy to hold: guilt, fear, threats to identity and livelihood.
Why Disasters Don’t Automatically Wake Us Up
You would think that living through a climate disaster makes people climate advocates. Apparently not. A 2025 study in Nature Climate Change, led by Viktoria Cologna at ETH Zurich, surveyed more than 70,000 people across 68 countries and matched their answers against actual exposure to extreme weather. Merely experiencing disasters did not predict support for climate policy. What did was whether people attributed the disaster to climate change. The authors are careful to note that causality could run both ways, but the pattern is unambiguous: the connection between event and cause has to be made consciously. It doesn’t make itself.
And when the connection is too painful to make, some minds manufacture alternatives. After flash floods killed more than 130 people in Texas in July 2025, a conspiracy theory blaming a small cloud-seeding company spread so widely that the state’s agriculture commissioner had to publicly debunk it; similar theories about “directed energy weapons” went viral within hours of the Los Angeles fires. Low trust in institutions and algorithmic amplification did much of the spreading. But for at least some of the people embracing them, the appeal may be psychological: a weather machine is a villain you can name, blame and stop. A destabilized climate system, fed by a century of emissions, offers no such comfort. The conspiracy is not merely an explanation. It is a more bearable one.
The mechanism is not confined to the fringe. Whether the escape route is a weather machine among citizens or the language of competitiveness among ministers, the psychological service can be similar: an intolerable implication is exchanged for a manageable one.
Europe Thought It Was Immune
For years, Europeans could tell themselves that climate denial was an American disease. That story no longer holds. Denial is coming back to Europe, in its evolved form.
Take Sweden, long one of the most climate-aware countries in the world. A survey by Indikator Opinion for Swedish public television SVT, conducted in late July 2026 while hundreds of thousands of Europeans were fleeing wildfires in France and Spain, found that nearly 80 percent of Swedes see a strong connection between the heat records, the fires and climate change. Underneath, the number splits along identity lines: 85 percent of women see the connection against 68 percent of men, with a clear divide by party sympathy as well. Daniel Lindvall, the Uppsala University sociologist who studies climate attitudes, explained the gap in terms Norgaard would recognize instantly: “It becomes an unconscious defense of one’s identity and lifestyle, where you don’t connect extreme weather with the climate issue.”
The gap has a research pedigree: the much-cited “cool dudes” study found the same identity-protective pattern among conservative white men in the United States, for whom climate science reads less as information than as an accusation.
The same evolution is visible in European politics. Research covered by DeSmog shows that outright climate skepticism in far-right European Parliament speeches collapsed from 38% to 9% between 2004 and 2019, while acceptance of the science became the majority position within those same parties. They did not become climate advocates. They changed weapons, adopting what researchers call the discourses of climate delay: competitiveness, Chinese emissions, cost of living, someone else should go first. With those arguments they have helped delay the EU’s deforestation rules and unpick parts of the Green Deal. This form of denial is harder to fact-check, because it no longer disputes any facts.
Governments Are Not Patients. But They Are Run By People
An admission, before going further: political systems can’t be psychoanalyzed from a distance. Policy reversals have material causes: lobbying, elections, energy prices, industrial pressure, the security lessons of 2022. Some of the anxieties behind them are legitimate, and a handful of the rolled-back rules were arguably poorly designed. Voters worried about electricity bills are not suffering from a defense mechanism.
But the material explanation and the psychological one are not rivals. They interact, and two findings show how.
First, political parties are not automatically educated by catastrophe any more than citizens are. A 2024 study in Nature Climate Change analyzed more than 260,000 press releases from 68 European parties and found that extreme weather events did not increase parties’ attention to environmental issues. Green parties were the sole exception, and even their attention returned to baseline within a week. The smoke enters the capital without entering the agenda.
Second, threat can actively strengthen resistance. In a landmark study on system justification, Irina Feygina, John Jost and Rachel Goldsmith showed that people motivated to defend the existing social and economic order responded to environmental threat with more denial, not less, because acknowledging the crisis felt like an indictment of the system itself. Related research on how mortality reminders affect judgment, an influential though contested body of work, points the same way: danger makes people cling harder to the worldview that shields them.
This is the interaction that explains the past year. Researchers now distinguish climate obstruction, the organized and interest-driven blocking of action, from denial, the psychology that makes the blocking palatable. Inside boardrooms and ministries, much of what looks like denial is conscious rationalization of decisions already made. But rationalizations need customers, and that is where the psychology returns. The narratives succeed because they meet a demand for permission to accept the science without accepting its consequences. The fossil fuel lobby doesn’t need to convince anyone that climate change is a hoax. All it has to supply is that permission: energy security, affordability, competitiveness, “pragmatism.” Real economic anxieties make that language land harder, and the worse the climate news gets, the more welcome the comfort becomes. Again and again, the reversals I documented were justified in exactly those terms. The lobby’s real product is not doubt about the science. It is comfort about the implications.
What Breaks The Spell
The reason this is not a counsel of despair also comes from medicine: denial is rarely permanent. Studies of patients who initially react with distress show marked improvement within weeks, and what helps people take in threatening information without retreating from it is not more bad news but support, clear communication and a sense of agency. The climate research points to three of the same levers:
- Connect the event to the cause, immediately and explicitly. The 260,000 press release study shows attribution, not experience, travels with policy support. Every heatwave reported without its cause is a wasted teaching moment.
- Connect the cause to something actionable. Catastrophe without agency produces fatalism and avoidance, in politics as in oncology. Leaders, media and executives who pair every warning with a credible next step are working with human psychology instead of against it.
- Frame action as protection, not sacrifice. The system justification research found resistance fell sharply when change was presented as preserving and improving the system people value, what the authors call “system-sanctioned change.” Climate action defends energy security, health, food prices and industrial competitiveness. The side that owns the language of protection wins the psychology.
The public and the market, it should be said, are further along than the politics. In a global study of nearly 130,000 people in 125 countries, 89 percent demanded stronger climate action from their governments, yet the same study found that this majority dramatically underestimates its own size, a silence that leaders read as permission to retreat. Meanwhile the Alarmed outnumber the Dismissive by more than two to one, clean energy attracts nearly twice the investment of fossil fuels, and one in four new cars sold globally is now electric. The backsliding of the past year is not evidence that action has become impossible. It is evidence that facts and market momentum do not automatically become political courage, and that a defensive reaction to a threat moving closer is being amplified by interests skilled at converting psychological discomfort into policy.
Because the other thing the research on advanced illness makes brutally clear is this: denial does not change the diagnosis. It only shortens the time left to act on it.
