There are claims saying that American Physical Society, the leading professional organization for physicists, has reversed its position on global warming. The society stated in November 2007 that greenhouse gases from human activities affect the Earth's climate.
Recently, an article was submitted to an online newslatter of the APS forum on Physics and Society. It claimed that Intergovernmental Panel on Climate Change (IPCC) overestimated the Earth's climate sensitivity to carbon dioxide. The article also claimed that changes in solar activity are the reason behind the warming trend.
A note in red lettering above the article states and it has not been peer-reviewed. The Council of the American Physical Society disagrees with the conclusion of the article. In fact, APS reaffirms its previous statement by saying that, "The evidence is incontrovertible: Global warming is occurring."
