Increased Violence Linked to Climate Change
Well thank God they've stopped blaming TV and movies.
Shifts in climate are strongly linked to increases in violence around the world, a study suggests.
US scientists found that even small changes in temperature or rainfall correlated with a rise in assaults, rapes and murders, as well as group conflicts and war.
The team says with the current projected levels of climate change, the world is likely to become a more violent place.
The study is published in Science.
Marshall Burke, from the University of California, Berkeley, said: "This is a relationship we observe across time and across all major continents around the world. The relationship we find between these climate variables and conflict outcomes are often very large."
The researchers looked at 60 studies from around the world, with data spanning hundreds of years.
They report a "substantial" correlation between climate and conflict.
Their examples include an increase in domestic violence in India during recent droughts, and a spike in assaults, rapes and murders during heatwaves in the US.
The report also suggests rising temperatures correlated with larger conflicts, including ethnic clashes in Europe and civil wars in Africa.
Mr Burke said: "We want to be careful, you don't want to attribute any single event to climate in particular, but there are some really interesting results."
The researchers say they are now trying to understand why this causal relationship exists.
"The literature offers a couple of different hints," explained Mr Burke.
"One of the main mechanisms that seems to be at play is changes in economic conditions. We know that climate affects economic conditions around the world, particularly agrarian parts of the world.
"There is lots of evidence that changes in economic conditions affect people's decisions about whether or not to join a rebellion, for example."
But he said there could also be a physiological basis, because some studies suggest that heat causes people to be prone to aggression.
"It is a major priority for future research to distinguish between what is going on in each particular situation."
The scientists say that with the current projected levels of climate change the world is likely to become a more violent place.
Anyone who lives in Chicago during the summer knows well the correlation between heat and violent behavior. You could probably say the same thing about any big city in the western world.
But you just knew they were going to get around to this eventually in order to try and validate global warming theory. All the great plagues of mankind -- war, pestilence, disease -- have now been linked to global warming.
Next thing you know, they'll be predicting fire and brimstone hurtling down from the sky to destroy our cities, so repent now and support a carbon tax.
