Report: Global warming didn't cause big US drought | Business & Technology
"Last year's huge drought was a freak of nature that wasn't caused by man-made global warming, a new federal science study finds."
"This is one of those events that comes along once every couple hundreds of years," said lead author Martin Hoerling, a research meteorologist at the National Oceanic and Atmospheric Administration. "Climate change was not a significant part, if any, of the event."
"Other scientists have linked recent changes in the jet stream to shrinking Arctic sea ice, but Hoerling and study co-author Richard Seager of Columbia University said those global warming connections are not valid."
And one more time, with four-part harmony and feeling:
"Hoerling noted that in the past 20 years, the world is seeing more La Ninas, the occasional cooling of the central Pacific Ocean that is the flip side of El Nino. Hoerling said that factor, not part of global warming but part of a natural cycle, increases the chances of such droughts."
