A Scientific Feud: Does Global Warming Make Us More Violent?



A group of scientists recently released a paper claiming that global warming makes violent conflict more likely. Others, though, have sharply criticized the study, leading to a widening scientific tiff. In related news, it has been a hot summer.

There's a widely held assumption that climate change will have horrific consequences, not only for the environment but also for its inhabitants. As resources become scarcer, the logic goes, the number of violent conflicts across the globe will increase. At first glance, the claim would seem to make sense. And yet for the last 20 years, scientists have been debating the question as to whether global warming necessarily makes conflict more likely. A flood of studies on the subject has failed to provide much clarity. Some researchers see climate change as a danger to peace, some don't. Still others believe that global warming could even reduce the risk of war.

Given the lack of consensus, a recent study that appeared in the respected journal Science was all the more astounding. A team led by Solomon Hsiang from the University of California, Berkeley analyzed 60 studies from a variety of disciplines and came to the conclusion that global warming clearly increases the danger of violent conflict. Should average temperatures increase by 2 to 4 degrees Celsius (4 to 7 degrees Fahrenheit) by 2050 as forecast, the study claimed, armed conflict could increase in some regions by as much as 50 percent.
