Aftermath of a plane bombing in Serekaniye, Syria
This week, the exiled head of the Syrian opposition movement said he would meet representatives of President Bashar al-Assad in Geneva, a promising turn for a conflict that has left 100,000 dead, including many civilians, since spring 2011. It has been a long, bitter battle, but for many Syrians one root of the violence stretches back to several years before al-Assads troops began picking off anti-government protesters. Beginning in 2006, a prolonged, severe drought decimated farmland, spiked food prices, and forced millions of Syrians into poverty helping to spark the unrest that eventually exploded into civil war.
The Syrian conflict is just one recent example of the connection between climate and conflict, a field that is increasingly piquing the interest of criminologists, economists, historians, and political scientists. Studies have begun to crop up in leading journals examining this connection in everything from the collapse of the Mayan civilization to modern police training in the Netherlands. A survey published today in Science takes a first-ever 30,000-foot view of this research, looking for trends that tie these examples together through fresh analysis of raw data from 60 quantitative studies. It offers evidence that unusually high temperatures could lead to tens of thousands more cases of interpersonal violence murder, rape, assault, etc. and more than a 50 percent increase in intergroup violence, i.e. war, in some places.
This is what keeps me awake at night, lead author Solomon Hsiang, an environmental policy post-doc at Princeton, said. The linkage between human conflict and climate changes was really pervasive.
Any cop could tell you that hot days can make people snap last summer veteran police boss William Bratton argued that a warm winter contributed to a rash of murders in Chicago. But Hsiang and his colleagues wanted to see how this pattern held up across the globe, at different times and with different kinds of conflict, to gauge just how much the climate can lead to violence.
