US Study: Global Warming Makes People Violent

TEXT SIZE - +
A group of U.S. scientists says it has found another consequence of global warming -- anger.

A study in the journal Science says that as global temperatures get hotter, so does our temper.

The researchers looked at a connection between the Earth's climate and war dating back to 10,000 BC. They say people become more ill-tempered and violent even during slight rises in temperature or brief rainy periods.

This includes everything from more wars to domestic violence and even baseball pitchers deliberately throwing at batters.

One expert says the world will be a very violent place by the middle of the century if climate change continues.
