In Weather Chaos, a Case for Global Warming [Fraud] - NYTimes.com

“The climate is changing,” said Jay Lawrimore, chief of climate analysis at the National Climatic Data Center in Asheville, N.C. “Extreme events are occurring with greater frequency, and in many cases with greater intensity.”

Theory suggests that a world warming up because of those gases will feature heavier rainstorms in summer, bigger snowstorms in winter, more intense droughts in at least some places and more record-breaking heat waves. Scientists and government reports say the statistical evidence shows that much of this is starting to happen.

“If you ask me as a person, do I think the Russian heat wave has to do with climate change, the answer is yes,” said Gavin Schmidt, a climate researcher with NASA in New York. “If you ask me as a scientist whether I have proved it, the answer is no — at least not yet.”

“Global warming, ironically, can actually increase the amount of snow you get,” said Kevin Trenberth, head of climate analysis at the National Center for Atmospheric Research in Boulder, Colo. “But it also means the snow season is shorter.”

In general, the research suggests that global warming will worsen climate extremes across much of the planet. As in the United States, wet areas will get wetter, the scientists say, while dry areas get drier.

But the patterns are not uniform; changes in wind and ocean circulation could cause unexpected effects, with some areas even cooling down in a warmer world.
