After publication of this story, the APS responded with a statement that its Physics and Society Forum is merely one unit within the APS, and its views do not reflect those of the Society at large.
The American Physical Society, an organization representing nearly 50,000 physicists, has reversed its stance on climate change and is now proclaiming that many of its members disbelieve in human-induced global warming. The APS is also sponsoring public debate on the validity of global warming science. The leadership of the society had previously called the evidence for global warming "incontrovertible."
In a posting to the APS forum, editor Jeffrey Marque explains,"There is a considerable presence within the scientific community of people who do not agree with the IPCC conclusion that anthropogenic CO2 emissions are very probably likely to be primarily responsible for global warming that has occurred since the Industrial Revolution."
The APS is opening its debate with the publication of a paper by Lord Monckton of Brenchley, which concludes that climate sensitivity -- the rate of temperature change a given amount of greenhouse gas will cause -- has been grossly overstated by IPCC modeling. A low sensitivity implies additional atmospheric CO2 will have little effect on global climate.
Larry Gould, Professor of Physics at the University of Hartford and Chairman of the New England Section of the APS, called Monckton's paper an "expose of the IPCC that details numerous exaggerations and "extensive errors"
In an email to DailyTech, Monckton says, "I was dismayed to discover that the IPCC's 2001 and 2007 reports did not devote chapters to the central 'climate sensitivity' question, and did not explain in proper, systematic detail the methods by which they evaluated it. When I began to investigate, it seemed that the IPCC was deliberately concealing and obscuring its method."
According to Monckton, there is substantial support for his results, "in the peer-reviewed literature, most articles on climate sensitivity conclude, as I have done, that climate sensitivity must be harmlessly low."
Monckton, who was the science advisor to Britain's Thatcher administration, says natural variability is the cause of most of the Earth's recent warming. "In the past 70 years the Sun was more active than at almost any other time in the past 11,400 years ... Mars, Jupiter, Neptune’s largest moon, and Pluto warmed at the same time as Earth."

quote: Emissions of greenhouse gases from human activities are changing the atmosphere in ways that affect the Earth's climate. Greenhouse gases include carbon dioxide as well as methane, nitrous oxide and other gases. They are emitted from fossil fuel combustion and a range of industrial and agricultural processes.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.Because the complexity of the climate makes accurate prediction difficult, the APS urges an enhanced effort to understand the effects of human activity on the Earth’s climate, and to provide the technological options for meeting the climate challenge in the near and longer terms. The APS also urges governments, universities, national laboratories and its membership to support policies and actions that will reduce the emission of greenhouse gases.
