“[T]listed below are doubtless limits of adaptation to excessive temperatures and these are decrease than these set by our mere physiological limits,” mentioned Levermann, as reported by Euronews.

The researchers selected Twitter due to the geolocation of lots of its tweets and since a fifth of Individuals use the platform. Between noon and late afternoon, when peak temperatures are normally recorded, can be excessive time for tweeting.
“For hundreds of years, researchers have grappled with the query of how local weather situations have an effect on human behaviour and societal stability,” mentioned PIK researcher and one of many examine’s authors Leonie Wenz, as reported by The Unbiased. “Now, with ongoing local weather change, it’s extra vital than ever.”
