Hot weather kills! More specifically, hot weather turns human beings into ruthless killing machines! So is the info gained from a new study performed by researchers at Princeton University and UC Berkeley, and published today in the journal Science. The study focused on finding the correlation between increased temperature, and rates of violence, murder, and war. The researchers were able to establish a clear relationship between hotter weather and higher incidents of violence, war, and murder.
In the study, researchers analyzed 60 previous studies on periods of violence, stemming as far back at 10,000 B.C. The researchers then correlated this data with weather and temperature records to see if hotter days correlated with more violence and murder. The researchers concluded that in months in which the temperature shifted five degrees warmer than average, rates of violence increased by 4% and rates of group conflict increased by 14%.
These results are impressive, as they stay consistent throughout multiple centuries and millennia. The results did not state that hot months like July led to violence, but instead that when any month was five degrees hotter than usual, people started killing each other.
The research team does not have a definitive answer to why this increase in violence occurs. The prevailing theory is that that heat leads to doubt, and thus leads to hunger and unemployment. Unhappy citizens are more likely to start wars or get into fights.
I offer a counter theory: it sucks when it’s too hot out. It was like 108 degrees last month, and I still want to fight my coworkers when I remember how angry that made me.
