its not all the scientists... its only the liars like Mann and Trenberth. who are attempting to blame agw. t
ask your beloved NOAA.

Natural weather patterns, not man-made global warming, are causing the historic drought parching California, says a study out Monday from federal scientists.
"It's important to note that California's drought, while extreme, is not an uncommon occurrence for the state," said Richard Seager, the report's lead author and professor with Columbia University's Lamont Doherty Earth Observatory. The report was sponsored by theNational Oceanic and Atmospheric Administration. The report did not appear in a peer-reviewed journal but was reviewed by other NOAA scientists.
"In fact, multiyear droughts appear regularly in the state's climate record, and it's a safe bet that a similar event will happen again," he said.

California floods during worst drought in 1,200 years
The persistent weather pattern over the past several years has featured a warm, dry ridge of high pressure over the eastern north Pacific Ocean and western North America. Such high-pressure ridges prevent clouds from forming and precipitation from falling.
The study notes that this ridge — which has resulted in decreased rain and snowfall since 2011 — is almost opposite to what computer models predict would result from human-caused climate change.
The NOAA report says midwinter precipitation is projected to increase because of human-caused climate change over most of the state. Seager said a low-pressure system, not a high-pressure system, would probably form off the California coast because of climate change.
Low pressure creates clouds and precipitation.
Some outside climate scientists criticized the report, saying it didn't take into effect how record warmth worsened the drought.
