Injuries and fatalities will rise due to climate change, says a new study.

The study, conducted by researchers at Columbia and Harvard, can be found in ‘Nature Medicine.’

Researchers analyzed U.S. fatalities from injuries over a 37-year period until 2017. The number of deaths were then associated with big temperature swings each month. Because of the temperature swings, authors say an extra 2,135 people could die annually in the U.S. Besides drownings and falls, the study includes human assaults related to climate change.

Researchers add that higher temperatures are linked to increased aggravation in people. They also point out that hotter climates lead people to consume more alcohol. This may relate to transportation accidents, which the study says make up many recorded deaths when the temperatures are not normal.
