Researchers at Potsdam Institute for Climate Impact Research (PIK) revealed how global heating fuels online hate speech. The study is published in two journals, The Lancet Planetary Health and Environmental Research Letters.
In order to understand the temperature impacts on hate speech online, the researchers surveyed 4 billion tweets posted on Twitter, in the US, between the years 2014–2020. They used a machine-learning approach to identify the tweets that comprised English-phrased hate words or displayed aggressive online behavior.
The results revealed that hate speech on social media is greatly influenced by temperature and weather conditions. In fact, extreme weather fuels online hate speech.
It was found that the minimum of hate tweets is reached for temperatures 15–18°C. On the other hand, temperatures above or below a feel-good window of 12-21 degrees Celsius (54-70 °F) are greatly associated with increased hate speech.
One of the lead researchers, Anders Levermann, elaborated: “Even in high-income areas where people can afford air condition and other heat mitigation options, we observe an increase in hate speech on extremely hot days.”
Researchers are hopeful that the study will contribute to a better understanding of several interlinked factors that impact mankind. These include limits of human adaptation to extreme temperatures, the societal impact of climate change, conflict in the digital sphere and societal cohesion, as well as mental health.
