Global Warming not to blame for Drought

Study Reveals Global Warming Not To Blame For Last Year’s Crippling Drought
 
 
A new federal study reveals that global warming is not to blame for last year’s extreme drought that crippled the central Great Plains.
 
The study conducted by the National Oceanic and Atmospheric Drought Task Force places the blame on natural variations in weather patterns that caused the “flash drought.”
 
The Plains saw very little rain last summer due to two key meteorological processes which NOAA states was a “sequence of unfortunate events.” First, the Plains states saw very little rain in May and June because low pressure systems that brought storms were shunted northward into Canada. Second, thunderstorms were infrequent in July and August and produced little precipitation.
 
The report states that there were “no strong indicators” a drought of this magnitude would have struck the Midwest last year.
 
“This is one of those events that comes along once every couple hundreds of years,” lead author Martin Hoerling, a research meteorologist at NOAA, said. “Climate change was not a significant part, if any, of the event.”
