Large-Scale Study Shows Global Warming Has Adverse Effects On Mental Health

In fact, the organization says that we have until 2030 to stop climate change; if not, temperatures could exceed a threshold level. In a new study, researchers found that along with increasing global temperatures comes a corresponding increase in mental-health issues.

Half of all mental disorders begin at the adolescent age - before the age of 14 - but most cases go undetected and untreated, the World Health Organisation (WHO) has said. He looked at self-reported mental health data for over two million United States residents between 2002 and 2012 and compared it to the meteorological records. He warned that a 2 degree Celsius rise can push human mental health over the edge. In this report, respondents had to answer how many days during the last month they felt that their mental health was not very good, including depression, stress, and emotions.

"Short-term exposure to more extreme weather, multiyear warming, and tropical cyclone exposure each associate with worsened mental health", MIT researchers found.

And another study - looking at 17 years of data from Milwaukee, Wisconsin, on heat waves and hospital admissions - also found an increase of people coming to the hospital for "self-harm" during warmer times of the year. Using recent national meteorological data as well as mental health data from the CDC, the study's authors found that a one-degree Celsius increase in average temperature was linked to a two percentage point increase in the public prevalence of mental-health issues over a five-year period. "For example, is poor sleep due to hot temperatures the thing that produces mental health problems?" "Yet for too long, mental health has been mostly an afterthought, despite its overwhelming impacts on communities and young people, everywhere".

Exposure to natural catastrophes such as hurricanes saw a 4 percent increase in mental health difficulties. Further low-income individuals seemed to be affected more (60 percent more) with climate change than other income groups.

Researchers have added a note to their study saying that the major limitation of this study was that the data came from a developed nation and from temperate climates. They called for more studies in the "regions with less-temperate climates, insufficient resources, and a greater reliance on ecological systems" and predicted that these regions may have more "severe effects of climate change on mental health".

"While the precise magnitude of these climate-induced adversities is hard to estimate, the theoretical relationship between climate change and mental health risk is compelling", the study author notes.
