As TVs across Florida broadcast the all-too-familiar images of a powerful hurricane headed for the coast in early October 2024, people whose homes had been damaged less than two weeks earlier by Hurricane Helene watched anxiously. Hurricane Milton was rapidly intensifying into a dangerous storm, fueled by the Gulf of Mexico’s record-breaking temperatures.

Many residents scrambled to evacuate, clogging roads away from the region. Officials urged those near the coast who ignored evacuation warnings to scrawl their names on their arms with indelible ink so their corpses could be identified.

The two hurricanes were among the most destructive in recent memory. They are also stark reminders of the increasingly extreme weather events that scientists have long warned would be the consequence of human-driven climate change.

Still, many people deny that climate change is a worsening threat, or that it exists at all. As its impacts grow more visible and destructive, how is this possible?

One answer lies in a unique facet of human psychology—specifically, in how people manage the fear aroused by existential threats. For many people, denying the existence of a climate crisis is not only convenient, but may feel psychologically necessary.

Terror management theory

The Pulitzer Prize-winning anthropologist Ernest Becker put it this way: “The idea of death, the fear of it, haunts the human animal like nothing else . . . to overcome it by denying it in some way is the final destiny for man.”

In plain terms, he was saying that most people struggle to accept their mortality and take pains to distort their perception of reality to avoid confronting it.

In the 1980s, social psychologists developed “terror management theory,” showing the lengths people go to deny death. Hundreds of experiments have tested its implications. In a common method, participants reflect on their own death, while control groups consider less threatening topics, like dental pain. The key question: What does death awareness do to people?

After writing about death, people tend to quickly move on, pushing thoughts of it from consciousness with distractions, rationalizations, and other tactics. Healthcare professionals see this every day. For example, people often dodge screenings and diagnostic tests to avoid the frightening possibility of discovering cancer.

But here’s the rub: Terror management theory suggests that when people are not thinking about death, it nevertheless holds influence. The unconscious mind lingers on the problem even after people have used strategies to quiet the fear by pushing it from awareness.

Social psychology experiments show that people often cope with the specter of death by attaching themselves to cultural ideologies, such as religious, political, or even sports fandom. These worldviews imbue life with meaning, values, and purpose. And that can ease the terror of mortality by connecting people to an enduring and comforting web of ideas and beliefs that transcend one’s own existence.

When people are made aware of death, those systems of meaning become even more critical to their psychological functioning. Existential threats make us cling even tighter to the meaning systems that sustain us.

Climate denial as a defense mechanism

Much like a terror management lab experiment—or the onset of the COVID-19 pandemic—natural disasters like hurricanes Helene and Milton trigger death anxiety.

Rising sea levels, warming oceans, and intensifying storms—all tied to global warming fueled by human actions—represent an existential threat.

From our perspective, it is not surprising that climate-related disasters disappear from the public consciousness almost as soon as they have passed. Google Trends data exemplifies this: Incoming storms instigated an uptick in searches for “climate change” and “global warming” in the days before Hurricane Helene made landfall on September 26, and Hurricane Milton on October 9. Then those searches quickly declined as people shifted their focus away from the threat.

Unfortunately, climate change isn’t going away, no matter how hard anyone tries to deny it.

While climate denial allows people to protect themselves from feelings of distress, terror management theory suggests that denying death is just the tip of the iceberg. For some people, accepting the reality of climate change would necessitate reevaluating their ideologies.

Terror management theory predicts that individuals whose ideologies conflict with environmental concerns may ironically double down on those beliefs to psychologically manage the existential threat posed by climate-related disasters. It’s similar to how mortality reminders can lead people to engage in risky behavior, such as smoking or tanning. Hurricanes may reinforce denial and commitment to a worldview that rejects climate change.

A path forward: Building new worldviews

Although denial may be a natural psychological response to existential threats, the U.S. may be getting to a point where even deniers can’t ignore the existential threat associated with climate change.

Again and again, Americans are gobsmacked by the devastation—from hurricanes to severe flooding, wildfires, and more.

A terror management analysis suggests that overcoming this crisis requires weaving a solutions-focused narrative into the ideologies that people rely on for comfort. As psychologists who work on terror management, we believe the fight against climate change should be framed not as an apocalyptic battle that humanity is destined to lose, but as a moral and practical challenge that humanity can collectively overcome.

Tampa, Florida, meteorologist Denis Phillips had the right idea as the two hurricanes headed for his community: His fact-based social media updates eschew partisan critique, encourage neighbors to support one another, and emphasize preparedness and resilience in the face of incoming storms.

As Milton approached, Phillips told residents to remember his Rule #7: Don’t freak out. That doesn’t mean do nothing; it means evaluate risks without letting emotion interfere, and take action.

Shifting the narrative from helplessness to collective empowerment and action can help people confront climate change without triggering the existential anxieties that lead to denial—offering a vision for a future that is both secure and personally meaningful.
