Science research (and implementation) nowadays produces all sorts of headlines that are of significant interest to the public and policymakers.
But, as seems to be the case, the natural processes of climate change, global warming and global cooling appear to bring the quack scientists with truly quack theories out of the ivy towers in search of more research funding.
Case in point: the Ohio State researchers who claim that a warmer climate produces more violence - this "new" theory that hotter temperatures cause more aggression has been easily debunked before (and debunking this theory is kinda like shooting politically correct fish in a barrel).

For an abundance of similar headlines that reflect violence across a wide range of climates, go here.
These most recent headlines firmly establish that aggressive violence is likely more a result of demographics (i.e. societal, cultural and religious backgrounds) than climate. In other words, you can take someone out a violent area with a very warm climate and nothing basically changes - well.....other than civilization just gets more violence in the cooler climate, obviously.
