Scientists: Global warming is not causing harsh winter weather

As one university-based climatologist said: ‘Such claims make no sense’. The climate isn’t doing as predicted so far-fetched excuses are produced by climate alarm promoters.

Record snowfall, a “bomb cyclone” and cold Arctic air have once again stirred up the debate over global warming’s impact on winter weather, says Michael Bastasch at The Daily Caller.

Some climate scientists are pointing the finger at manmade global warming as a culprit behind recent wintry weather, but there’s not a lot of evidence or agreement that global warming is currently driving extreme cold and snow.

Penn State University climate scientist Michael Mann authored a blog post for the Climate Reality Project, former Vice President Al Gore’s group, claiming what’s happening is “precisely the sort of extreme winter weather we expect because of climate change.” Mann’s argument is that we can expect more “bomb cyclones” and cold snaps as the planet warms.

But Mann, who often invokes the “consensus” on global warming, seems out of step with the evidence on this issue.

Kevin Trenberth, a scientist with the National Center for Atmospheric Research, said “winter storms are a manifestation of winter, not climate change.”

“The Arctic is greatly affected by climate change and it has a feedback effect – but not in winter,” Trenberth told The Daily Caller News Foundation. “It is not a cause but a part of climate change.”

“Such claims make no sense and are inconsistent with observations and the best science,” University of Washington climatologist Cliff Mass said of claims made by Mann and others. “The frequency of cold waves have decreased during the past fifty years, not increased. That alone shows that such claims are baseless.”

“And on a personal note, it is very disappointing that members of my profession are making such obviously bogus claims,” Mass said. “It hurts the science, it hurts the credibility of climate scientists, and weakens our ability to be taken seriously by society.”
