A skeptic of catastrophic man-made "global warming" is applauding a Nobel Prize winner for saying President Obama is "dead wrong" on the subject.

Ivar Giaever, Ph.D. won among the Nobel Prize winners for physics in 1973. In 2008, he was among several Nobel laureates to sign a letter endorsing then-Senator Barack Obama for president, saying then that "the country urgently needs a visionary leader who can ensure the future of our traditional strengths in science and technology and who can harness those strengths to address many of our greatest problems." Climate change was listed among those problems.

Since that endorsement, Dr. Giaever has expressed skepticism about climate change/global warming, telling a recent gathering (July 1) in Europe that Obama and others have it all wrong.

Marc Morano of Climate Depot spoke with OneNewsNow about Giaever's comments.

"Ivar Giaever is not happy with the president he endorsed," Morano understates, "and now says President Obama is ridiculous and 'dead wrong' on global warming – and he says that Obama is being misled by his advisors."

Individuals, organizations and websites are critical of scientists from "non-climate fields" expressing skepticism about global warming or climate change. SkepticalScience.com says they believe they have sufficient expertise to understand climate change despite having done minimal research on the subject." Coincidentally, SkepticalScience.com says Giaever "fits this mold perfectly." Still, skeptics – or "deniers," as they are now described in some circles – dismiss these and other claims as partisan.

Meanwhile, Morano points out Giaever isn't alone in his remarks about global warming.

"Dr. Caleb Rossiter, American University climate statistician, an anti-war Democrat ... is now appalled and says President Obama is 'delusional' on global warming. And there are other ones like Professor Dennis Rancourt out of Canada."

Rossiter admits that since converting to a climate skeptic he has felt "very isolated" on the Democratic Party left – and calls Al Gore's pro-climate change film An Inconvenient Truth "a wonderful teaching tool because it shows how we don't do science."
