Our Brains Are Accelerating the Climate Catastrophe
Investments in brain health and brain skills are key to sustaining the environment and navigating the complexities of social-ecological challenges.
COMMENTARY
Brain health is intricately linked with climate change; when one improves so does the other, and vice versa. Overcoming evolutionary cognitive biases can both improve brain health and equip us to prevent climate change. Conversely climate change and environmental collapse may significantly harm brain health.
Denialism and Other Cognitive Maladies
Science denialism is a major hurdle to managing many global crises. For example, denialism has had devastating consequences in the COVID-19 pandemic. Science denialism
Psychological factors make fighting misinformation a difficult task. For one, misinformation is sticky. Cook writes that “Once people internalize misinformation, it is notoriously difficult to dislodge.”2 Additionally, misinformation is compelling, and human beings have an innate proclivity for consuming denialist media. Vosoughi et al, analyzing 12 years of Twitter data, found that fake news stories spread much faster on Twitter than real news—and individuals are to blame for their circulation, not bots. Fake news stories “diffused significantly farther, faster, deeper, and more broadly than the truth in all categories of information.”3 True news stories took about 6 times longer to reach 1500 people on Twitter than hoax stories, according to the study. As the satirist
Even without direct denialism, the human brain is hard-wired to underestimate the threat of the climate crisis. Matthew Wilburn King, writing for the BBC,
Furthermore, there is a sort of climate change bystander effect, with the APA stating that “many people… believe that others should act, or believe that their actions will make no difference or are unimportant compared to those of others.”5 The upshot is that fighting climate change is as much a psychological battle as it is a political or economic one. Together, we must overcome the cognitive barriers to popular acceptance of the realities of climate change.
The Interplay Between Brain Health and Climate Change
There is growing recognition that fostering brain skills will be crucial to confronting climate change. Cook recently developed the “Cranky Uncle” game to teach individuals about logical fallacies and critical thinking in the context of climate change. In the game, players must identify the form of science denial that matches the possible arguments of a climate denialist, such as “How can models predict climate 100 years out when they can’t get the forecast right next week?” and “Climate models are imperfect so they can’t be trusted.”
But the ties between the brain and the climate go even further. Just as improving brain health can help avert climate change or create preparedness should a changed climate eventually result in environmental collapse, climate change may significantly harm brain health. Nancy Sicotte, chair of the Department of Neurology at Cedars-Sinai Hospital in Los Angeles,
All in all, the relationship between climate change and the brain resembles a vicious cycle: the climate crisis worsens brain skills, and diminished brain skills perpetuate climate inaction or rejection of the scientific consensus. To break the cycle, we must develop a plan to improve brain health and brain skills at scale. But how?
The Road to Better Brain and Climate Health
In the corporate world, the use of metrics is vital to accomplishing directives. Want a happier staff? Start tracking employee well-being. Want more loyal customers? Start recording net promoter scores. Or, more pertinently, as many companies attempt to foster a sense of corporate purpose that may value priorities like environmentalism, researchers have suggested an
In light of this, we have launched the
Humans are embedded in, rather than apart from, the world as a global ecosystem, meaning our health and welfare can eventually be dragged down by ecosystem deterioration. Such may be the case if our global climate shifts into an irreversible Hothouse Earth,
