A massive new study finds that aggressive acts like committing violent crimes and waging war become more likely with each added degree of temperature. The study was published online yesterday by the journal Science.

In war-torn Africa, it says, every added degree Fahrenheit increases the chance of conflict between groups— rebellion, war, civil unrest — by 11 to 14%

For the United States, for every increase of 5.4 degrees Fahrenheit, the likelihood of violent crime goes up 2-4% (likely by 2065).
