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.
A recent lame paper by researchers desperately trying to tie Syrian violence with global warming and climate change was completely eviscerated by a wide range of experts...in summation, it was an exceedingly stupid paper...plus, history of climate antiquity provides plenty of evidence that cooler temperatures provoke more war, rebellions and organized violence than warmer periods.....

This chart depicts historical precipitation and temperature reconstruction from northern China.
Overlaid on the chart by 'C3' are significant Chinese events from the past, along with identification of major solar states (minimums and maximums).
The scientists who compiled the precipitation/temperature records and produced the reconstructions had summarized that solar influence was climatically significant for China due to the affect on annual monsoons.
Using Wikipedia, major war/violence/political events were identified and then added to the chart (color bars).
To the more than casual viewer, it would certainly appear that a cooler climate regime has a higher association with extreme organized violence than a warmer period.
The chart's green curve indicates that those periods with less precipitation (i.e. droughts) are more common when cooler temps prevail - more arid conditions, with less food production make people (and societies) rather restless.
The unequivocal and indisputable climate research clearly demonstrates that climate change is constant; and when combined with historical accounts and anecdotal evidence, warmer climates tend to favor prosperity and peace outcomes while cooler periods provide more of the opposite.
Note: 'C3' originally wrote about this research in 2011. There was a recent article at Ice Age Now (and a YouTube video) using another 'C3' chart with significant Chinese events being overlaid on the Greenland ice core temp reconstructions (that prompted our doing the same for the above northern China chart).

Read here. Global warming alarmists and agenda-driven pundits frequently spread the meme that global warming will cause more wars, leading to all sorts of imagined scenarios of mayhem, destruction and death later this century and next. Is there any actual empirical evidence backing these more-war claims up? Nope.
In a new peer-reviewed study, researchers examine the empirical evidence and find the claims of retired, fat- assed admirals and generals (real and the armchair variety) to be without merit. Surprised?
"In their conclusions, the authors state “We present some evidence that periods with lower temperatures in the pre-industrial era are accompanied by violent conflicts”, consistent with what others had found in China. Furthermore, they note “If anything, lower temperatures imply violence, and this effect is much weaker in the modern world than it was in pre-industrial times. This implies that future global warming is not likely to lead to (civil) war between (within) European countries.”.....Another popular claim about global warming is once again not supported by what has been observed for centuries – sound familiar?"
Blue/green colors indicate a low correlation between high temperatures and violence. Red reveals the high correlation regions.
Of course, per the evidence, Turkey and the Balkans appear to have a strong correlation with warmth and war. Or, is that a correlation between a certain religion and war/terrorism? And what about Iceland? Yep, them damn Vikings and their distant relatives were pretty frisky during the Medieval Warming until the icy depths of the Little Ice Age finally put Iceland and Greenland back in the deep freezer.
