Global warming poses risks to mental health according to a review by the American Psychological Association. Increased temperatures are linked to more alcohol and substance abuse as well as increased violence. Food and water shortages threaten security and cause problems like PTSD. Prolonged drought in Australia leads to "solastalgia," distress over environmental losses. Poor air quality raises anxiety. Panic and hysteria may arise from diseases. Those with schizophrenia face particular risks. Overall, climate change risks large-scale conflicts over displacement and scarce resources. However, most countries have inadequate mental healthcare resources for climate-related issues compared to physical healthcare. Psychology can help understand behaviors driving climate change to help address this global problem.
