Climate change has caused more intense wildfires, heat waves, floods and hurricanes, lengthened allergy seasons and inflicted other forms of tangible harm. But an oft-overlooked consequence — one that warrants urgent attention and creative problem-solving — is worsening mental health. The COVID pandemic has been a time of enormous suffering. According to the World Health Organization, the prevalence of depression and anxiety increased 25% globally during the first year of the pandemic. We are bruised and vulnerable, struggling to right ourselves after a tumultuous two and a half years. But the daily reminders of global warming, including extreme heat, water rationing and parched landscapes, are threatening to worsen the situation, and we don’t have medications or vaccines to save us.

Climate change has direct effects on mood Heat itself is associated with mental illness. Mood disorders, anxiety and aggressive behavior have been linked to higher temperatures. A 2019 study published by the National Bureau of Economic Research, found that violent crime in Los Angeles increased by 5.7% on days when temperatures rose above 85 F compared to cooler days. Authors of a 2018 study in the journal Nature predicted warmer temperatures could lead to as many as 40,000 additional suicides in the U.S. and Mexico by 2050.

“There is a direct link, and mental health and psychosocial well-being will decline as climate change pressures increase,” said Kerry Wangen, a psychiatrist in private practice in Southern California. People who face climate-related natural disasters frequently struggle with mental health problems. Hurricanes and wildfires lead to deaths and property destruction in the short-term. But they also contribute to depression, anxiety, post-traumatic stress disorder and suicidal thoughts. Droughts can disrupt food and water supplies and lead to loss of livelihood, which can push families and whole communities into poverty, a risk factor for mental illness. According to a Washington Post analysis, more than 40% of Americans live in a county that experienced an extreme weather event in 2021. Climate change also leads to the displacement of populations, as parts of the globe become uninhabitable due to sea-level rise, drought and other weather events. The result is more conflict and stress, both of which increase the odds of mental health problems. Grappling with pervasive fears The existential fear of climate change is a more pervasive concern, even if it is more subtle and less disabling than mental illnesses triggered by acute events. Fear of global warming leaves many of us feeling hopeless and powerless, dreading what is to come and sensing it is inevitable.
“Although I’ve never had a patient present primarily for climate-related anxiety, it’s common to discover that it’s there alongside other social and societal fears,” said Daniel Hochman, an Austin-based psychiatrist. A 2020 poll by the American Psychiatric Association found that 67% of Americans are somewhat or extremely anxious about the effects of climate change, and 55% are worried about its impact on their mental health. According to Hochman, climate anxiety — also referred to as “climate distress,” “climate grief” or “eco-anxiety”— can manifest as dysthymia, in which people are sad for the state of the world, and contribute to generalized anxiety disorder major depressive disorder, panic disorder and insomnia. For children and young adults, aware that they have the most to lose, the climate crisis is a common source of distress. In a global survey, published in The Lancet in December, nearly 60% of the 16- to 25-year-old respondents reported they were “very” or “extremely” worried about climate change. An additional 25% admitted feeling “moderately” worried. Over 45% said climate change has a negative impact on their daily lives.

What you can do about it During this summer of record-breaking heat, efforts to combat climate change have seen failure and triumph. On June 30, the U.S. Supreme Court undercut the Environmental Protection Agency’s ability to regulate carbon emissions. Last month, however, Congress passed legislation that will provide nearly $400 billion in tax credits for clean-energy pr …
