(The Washington Post) – Climate change is not only harmful to our physical health — it can be debilitating for our mental health as well, according to a report published Wednesday.

Severe weather events and natural disasters linked to climate change have the most dramatic impact on mental health, according to the report by the American Psychological Association and EcoAmerica: Natural disasters cause intense negative emotions in people who are exposed to them, primarily fear and grief. Anxiety, depression and unhealthy behavior are also common responses. Some people, particularly those who experience tragic events, such as the loss of a loved one or repeated exposure to extreme weather, develop post-traumatic stress disorder.

As one example of how disasters made more likely by climate change can affect mental health, the report cites statistics from people who survived Hurricane Katrina. Their rates of suicide and incidence of suicidal thoughts more than doubled, 1 in 6 people met the diagnostic criteria for PTSD, and nearly half of the people living in an affected area developed an anxiety or mood disorder such as depression.

“I found this topic really interesting because this wasn't something I was hearing people talk about and this wasn't well acknowledged as an effect of climate change,” said Susan Clayton, the lead author of the report and a professor of psychology at the College of Wooster in Ohio.

Some things can protect people from the worst psychological effects of climate-change-induced natural disasters, such as having social support. In contrast, those who live in communities where livelihood is directly tied to the environment, such as agriculture, tourism or fishing, are more vulnerable to negative mental-health impacts, according to the report. People in indigenous communities are particularly vulnerable because climate change can threaten environmental aspects of their cultural heritage.

Climate change can be a cause of stress, which is often caused by a sense of a loss of control or an inability to adapt to a new situation. Increased stress levels can increase the likelihood of problems such as substance abuse, anxiety disorders or depression, according to the report. [more]
