The relationship between environmental problems and human rights is underexamined. This is deplorable, because the most important environmental problem, namely climate change, is likely to have an adverse effect on human rights in lots of different ways.
For example, there is some data supporting the hypothesis that higher temperatures lead to an increase in crime, probably in part because high temperatures cause higher levels of aggression:
[H]igher temperatures lead to more assault and … the rise in violent crimes rose more quickly than the analogous rise in non-violent property-crime, an indicator that there is a “pure aggression” component to the rise in violent crime. …
Note that all crime increases as temperatures rise from 0 F to about 50 F. It seems reasonable to hypothesize that a lot of this pattern comes from “logistical constraints”, eg. it’s hard to steal a car when it’s covered in snow. But above 60 F, only the violent crimes continue to go up: murder, rape, and assault. The comparison between murder and manslaughter is elegantly telling, as manslaughter should be less motivated by malicious intent. …
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.
