Hotter Climate May Boost Conflict, From Shootings to Wars
Hotter Climate May Boost Conflict, From Shootings to Wars
It's a common enough axiom: when temperatures rise, tempers flare. And as climate change progresses, we can expect more extreme weather conditions around the world, from more intense storms to hotter summers—even now, heat waves are roasting the U.S. East Coast, the Pacific Northwest and the Middle East. In response, scientists are examining how rising temperatures are influencing conflict, both between individuals and on the national level. Are we headed for a future filled with more murders, skirmishes and outright war?
This week Generation Anthropocene producer Leslie Chang speaks with Stanford professor Marshall Burke, who studies how environmental change affects society. In a recent publication, Burke and his team analyzed multiple previous studies of the interaction between climate and conflict covering several disciplines. Their statistical approach revealed that the interplay goes far beyond anecdotal evidence.
"In 21 out of 21 studies, we saw a positive relationship between temperature and conflict. … The likelihood of that happening by chance is less than one in a million, right? So, this thing is real," Burke says.
One study the team looked at showed how abnormally hot summers affect police performance—when it's warmer than average, police perform worse on training exercises that involve decision-making while shooting. Other studies examined the link between changing climate and the collapse of historic civilizations, such as the Maya and the Anasazi. The team admits, though, that tracing the exact ways climate change triggers conflict is still a challenge, as many factors can influence a given scenario.

It looks like Americans can expect more unjustified police shootings in the future.
