I didn’t make that up:
Between 2010 and 2099, climate change will cause an additional 30,000 murders, 200,000 cases of rape, 1.4 million aggravated assaults, 2.2 million simple assaults, 400,000 robberies, 3.2 million burglaries, 3.0 million cases of larceny, and 1.3 million cases of vehicle theft in the United States.
The idea is simple and clean of course – warmer temperatures are associated with more criminal activity, and since climate change means a warmer planet it is “reasonable” to expect more bad stuff to happen when the planet gets warmer. But warmth does NOT cause any of these things. When you guys turn on the heat in your house during the winter and come in from outside, do you start beating your spouse? The paper indicates the pathways from temperature to crime, but citing the correlations says nothing about how easy or difficult it is to mitigate the problem.
Finally, for your thought, suppose you take this paper seriously. How do the results compare to the impact of US migration patterns on robbery, rape, assault, theft, etc? This map provides a glimpse of what has been happening over time:
