Global Warming to Blame for 37% of Droughts by Jaymi Heimbuch, San Francisco, California on 03.26.09 Science & Technology
It's a bit of a debate about exactly what role global warming is playing in droughts in Australia and the US, but at least one scientist has determined that it is 37% at fault for the decreased rainfall in the areas.
Melbourne University's Peter Baines noticed a trend when he analyzed several layers of statistics, including global rainfall. sea surface temperature data, and a reconstruction of atmospheric behavior over the last 50 years. The trend he saw was that over the last 15 years, global warming seems to be to blame for at least 37% of the drop in rainfall in the continental United States, southeastern Australia, a large region of equatorial Africa and the Altiplano in South America.
"The 37 percent is probably going to increase if global warming continues," Baines told Reuters from Perth in Western Australia, where he presented his findings at a major climate change conference. "This is all part of a global pattern where the rainfall is generally increasing in the equatorial tropics and decreasing in the sub-tropics in mid-latitudes," Baines said.
If it's any kind of inclement weather, blame it on Global Warming.
