Exposure to climate-related change and disasters can cause stress, grief, and a sense of loss, as well as clinical disorders like depression, anxiety, and post-traumatic stress disorder. Climate change can even contribute to suicidal behaviors. Direct and indirect impacts of climate change can strain social relationships and increase risk of substance abuse. It can impact everyday life and perceptions and experiences as people grapple with slow and sudden changes to our world, and even as people process the threat of change. Chronic stress can lead to other negative health effects like cardiovascular disease and worsening symptoms of diabetes.
Learning about and observing the many impacts climate change is having on the environment, reading about climate-related losses in populations and species, and fearing a loss of the ability to engage in traditional activities like hunting and gathering can cause or worsen stress, depression, and anxiety. Extreme weather events impact mental health, especially when they cause property damage and loss, social disruption, and displacement.
Climate change has financial implications for people who live off the land, and environmental changes like more severe and prolonged drought can impact mental health. For example, in the 1980’s, farmers in the Upper Midwest experienced record drought combined with declining land values, indebtedness, and unstable prices. During this time, rates of suicide among farmers in Montana, the Dakotas, Wisconsin, and Minnesota were double the national rate, as discussed here. This alarming trend has continued to present day, as explored in a recent article, which uses interviews and personal stories to examine the factors that might cause farmers to commit suicide, as well as potential solutions to the rural mental health crisis.
Physical health is linked to mental health. Since climate change is predicted to negatively impact some people’s physical health, it may affect their mental health as well. For example, as changes in temperature and precipitation increase allergens like ragweed pollen, people with sensitivity to ragweed pollen may find they are having more allergic reactions. Feeling sick may prevent people from doing things they enjoy, which can negatively impact mental health.
At a community level, climate change can increase interpersonal aggression, violence and crime, and social instability, and it can decrease community togetherness and cooperation.
Children, older adults, women (especially pregnant women and women who recently gave birth), people who already suffer from a mental illness, people living in poverty, and first responders are more at risk.
People who hunt, fish, gather, farm, ranch, or otherwise sustain themselves directly from the natural environment also are more at risk because their outdoor activities and livelihoods are likely to be impacted by climate change.
