Nobel prize winner for physics in 1973 Dr. Ivar Giaever resigned as a Fellow from the American Physical Society (APS) on September 13, 2011 in disgust over the group's promotion of man-made global warming fears.

Climate Depot has obtained the exclusive email Giaever sent to APS Executive Officer Kate Kirby to announce his formal resignation. Dr. Giaever wrote to Kirby of APS:

“Thank you for your letter inquiring about my membership. I did not renew it because I cannot live with the (APS) statement below (on global warming): APS: 'The evidence is incontrovertible: Global warming is occurring. If no mitigating actions are taken, significant disruptions in the Earth’s physical and ecological systems, social systems, security and human health are likely to occur. We must reduce emissions of greenhouse gases beginning now.'

Giaever announced his resignation from APS was due to the group's belief in man-made global warming fears. Giaever explained in his email to APS:

"In the APS it is ok to discuss whether the mass of the proton changes over time and how a multi-universe behaves, but the evidence of global warming is incontrovertible? The claim (how can you measure the average temperature of the whole earth for a whole year?) is that the temperature has changed from ~288.0 to ~288.8 degree Kelvin in about 150 years, which (if true) means to me is that the temperature has been amazingly stable, and both human health and happiness have definitely improved in this ‘warming’ period.’"

Giaever was one of President Obama's key scientific supporters in 2008. Giaever joined over 70 Nobel Science Laureates in endorse Obama in an October 29, 2008 open letter. In addition to Giaever, other prominent scientists have resigned from APS over its stance on man-made global warming.
