What Happens When Climate Change and the Mental-Health Crisis Collide?

From Nature:

Nearly one billion people worldwide — including one in seven teenagers — have a mental disorder. A growing body of research suggests that climate change is worsening people’s mental health and emotional well-being. Acute heatwaves, droughts, floods and fires fuelled by climate change cause trauma, mental illness and distress. So can chronic effects of global warming, such as water and food insecurity, community breakdown and conflict, as we report in a News feature.

Surveys are revealing that experiencing the effects of climate change — and awareness of the threat — can lead to psychological responses such as a chronic fear of environmental doom, known as eco-anxiety. Eco-distress, climate anxiety and climate grief are other terms used. In a 2021 survey of 10,000 people aged 16–25 in 10 countries, nearly 60% of respondents were highly worried about climate change, and more than 45% said their feelings about climate change affected their daily lives, such as their ability to work or sleep.

Such reactions to an existential threat are expected, and many people can handle these feelings on their own — but some need specialist help. Although there is anecdotal evidence that people with eco-anxiety are increasingly going to clinics, the psychological toll of climate change tends to be invisible — one reason why it has been neglected.
