Climate Change Research: Issues for the Atmospheric and Related Sciences
(Adopted by AMS Council on 9 February 2003) Bull. Amer. Met. Soc., 84, 508—515
Executive Summary
There is now clear evidence that the mean annual temperature at the Earth's surface, averaged over the entire globe, has been increasing in the past 200 years. There is also clear evidence that the abundance of greenhouse gases in the atmosphere has increased over the same period. In the past decade, significant progress has been made toward a better understanding of the climate system and toward improved projections of long-term climate change. Several national and international studies published in 2001 have provided reviews and assessments of the science of climate change. A National Research Council report concluded that "reenhouse gases are accumulating in the Earth's atmosphere as a result of human activities, causing surface air temperatures and subsurface ocean temperatures to rise. . . . The changes observed over the last several decades are likely mostly due to human activities, but we cannot rule out that some significant part of these changes is also a reflection of natural variability" (National Research Council 2001a). The Intergovernmental Panel on Climate Change (IPCC) reported that recent regional climate changes, particularly temperature increases, have already affected many physical and biological systems (McCarthy et al. 2001), and a national assessment on climate change impacts on the United States concluded that "natural ecosystems, which are our life support system in many ways, appear to be the most vulnerable to the harmful effects of climate change," but, "highly managed ecosystems appear more robust" http://www.ametsoc.org/POLICY/climatechangeresearch_2003.html
Federal Climate Change Science Program, 2006
On May 2, 2006, the Federal Climate Change Science Program commissioned by the Bush administration in 2002 released the first of 21 assessments that concluded that there is clear evidence of human influences on the climate system (due to changes in greenhouse gases, aerosols, and stratospheric ozone) <17>. The study said that observed patterns of change over the past 50 years cannot be explained by natural processes alone.
American Association for the Advancement of Science: "The scientific evidence is clear: global climate change caused by human activities is occurring now, and it is a growing threat to society."

Adopted in October 2006 Position Statement The Geological Society of America (GSA) supports the scientific conclusions that Earth’s climate is changing; the climate changes are due in part to human activities; and the probable consequences of the climate changes will be significant and blind to geopolitical boundaries. Furthermore, the potential implications of global climate change and the time scale over which such changes will likely occur require active, effective, long-term planning. GSA also supports statements on the global climate change issue made by the joint national academies of science (June 2005), American Geophysical Union (December, 2003), and American Chemical Society (2004). GSA strongly encourages that the following efforts be undertaken internationally: (1) adequately research climate change at all time scales, (2) develop thoughtful, science-based policy appropriate for the multifaceted issues of global climate change, (3) organize global planning to recognize, prepare for, and adapt to the causes and consequences of global climate change, and (4) organize and develop comprehensive, long-term strategies for sustainable energy, particularly focused on minimizing impacts on global climate.
US National Academy of Science: "In the judgment of most climate scientists, Earth’s warming in recent decades has been caused primarily by human activities that have increased the amount of greenhouse gases in the atmosphere.
