To track how global warming affects crime rates, Matthew Ranson examined 50 years of weather data around the country and corresponding crime statistics. Emily Badger summarizes his predictions:
By Ranson’s calculation, if global temperatures rise between now and 2099 by about 5 degrees Fahrenheit, as the Intergovernmental Panel on Climate Change has predicted, that could result over the next 90 years in an additional 30,000 murders in America (compared against a future in which climate change did not exist). Likewise, we could see 200,000 more rape cases, 1.4 million more aggravated assaults, 400,000 more robberies and 3.2 million burglaries.
