Feeling a little violent? Maybe it's hot outside
WASHINGTON, District of Columbia (AFP) - If the heat makes you cranky, take heart: you're not alone, according to a study out on Thursday in the United States (US) journal Science that links rising tempers to hot temperatures.
The link could have worrying implications as the Earth's climate warms, researchers at the University of California at Berkeley and Princeton University warned.
While making predictions about the future is always iffy, lead author Solomon Hsiang said the current trend is clear: hotter weather makes people more violent.
Hsiang and his fellow researchers conducted a meta-analysis of 60 studies across a range of disciplines, including archeology, climatology, political science and economics.
