A new study released indicates that as temperatures rise, hateful tweets sharply increase too.

The study, published this month by The Lancet Planetary Health, documented a 22% jump in racist, homophobic and misogynist tweets whenever temperatures were recorded above 42 degrees Celsius.

Conversely, however, the study showed that hateful tweets increased by 12% when temperatures dropped below minus 3 degrees Celsius. 

Data from the study relied on machine-learning algorithms which identified about 75 million hate tweets in written in English in 773 cities across the United States between May 1, 2014 and May 1, 2020. The tweets were documented and statistically compared with the local temperatures.

The hateful tweets dropped when temperatures were between 15 to 18 degrees Celsius.
