Psychological impact of climate change

The psychological impacts of climate change concerns effects that climate change can have on individuals' mental and emotional well-being. They may also relate to more generalised effects on groups and their behaviours, such as the urge to migrate from affected areas of the globe to areas perceived as less affected. These impacts can manifest in various ways and affect people of all ages and backgrounds. Some of the key psychological impacts of climate change include: emotional states such as eco-anxiety, ecological grief, eco-anger or solastalgia.^[1] While troublesome, such emotions may not appear immediately harmful and can lead to a rational response to the degradation of the natural world motivating adaptive action.^[2] However, there can be other effects on health, such as post-traumatic stress disorder (PTSD), for instance, as a result of witnessing or seeing reports of massive wildfires, which may be more dangerous.

Efforts to understand the psychological impacts of climate change have antecedents in work from the 20th century and even earlier, making evidence-based links to the changing physical and social environment resulting from accelerated human activity dating from the so called Industrial Revolution. Empirical investigation of psychological impacts specifically related to climate change began in the late 20th century,^[3] and have intensified in the first decade of the 21st century. From the early 2010s, psychologists were increasingly calling on each other to contribute to the understanding of psychological impacts from climate change. Academic, medical professionals, and various actors are actively seeking to understand these impacts, provide relief, make accurate predictions, and assist in efforts to mitigate and adapt to global warming including attempts to pause activity leading to further warming.^[4][5][6]

There are several channels through which climate change can impact a person's mental health, including direct impacts, indirect effects, and awareness of the issue. It has been observed that certain populations, such as communities of color, children, and adolescents, are particularly vulnerable to these mental health impacts. There are many exceptions, but generally it is people in developing countries who are more exposed to the direct impact and economic disruption caused by climate changes.^[2]

The psychological effects of climate change may be investigated within the field of climate psychology, or picked up in the course of treatment of mental health disorders. Non-clinical approaches, campaigning options, internet based support forums, and self-help books may be adopted by those not overwhelmed by climate anxiety. Some psychological impacts may not receive any form of treatment at all, and could be productive: for example, when concern about climate change is channeled into information gathering and seeking to influence related policy with others.^[2] The psychological effects of climate may receive attention from governments and others involved in creating public policy, by means of campaigning and lobbying by groups and NGOs.
