Temperature impacts on hate speech online: evidence from 4 billion geolocated tweets from the USA
Our results highlight hate speech online as a potential channel through which temperature
alters interpersonal conflict and societal aggression. We provide empirical evidence
that hot and cold temperatures can aggravate aggressive tendencies online. The prevalence
of the results across climatic and socioeconomic subgroups points to limitations in
the ability of humans to adapt to temperature extremes.
Temperature and Low-Stakes Cognitive Performance | Journal of the Association of Environmental and Resource Economists: Vol 11, No 1
Abstract This study offers some of the first evidence in a developing country context that transitory exposure to high temperatures may disrupt low-stakes cognitive activities across a range of age cohorts. By matching eight years of repeated cognitive tests among all the participants in a nationally representative longitudinal survey in China with weather data according to the exact time and geographic location of their assessment, we show that exposure to a temperature above 32°C on the test date, relative to a moderate day within 22°C–24°C, leads to a sizable decline in their math scores by 0.066 standard deviations (equivalent to 0.23 years of education). Further, the effect on the math test scores is more salient for individuals who are older or less educated.

New Paper Links Climate Change to Shrinking Brain Size in Humans
A new study suggests a link between past climate changes and a drop in the size of the human brain – an adaptive response that emerges in an analysis of climate records and human remains over a 50,000-year period.
