House Select Committee on Energy Independence and Global Warming, Final Staff Report for the 110th Congress Staff, October 21, 2008: “The scientific debate on the cause of climate change is over. A clear scientific consensus now holds that global warming is happening, that manmade greenhouse gas emissions are largely responsible, and that failure to dramatically reduce those emissions in the coming decades will result in catastrophic impacts. Human activities have changed the atmosphere as much in 200 years as natural variations changed it over 20,000 years. Atmospheric concentrations of carbon dioxidea key heat-trapping gashave increased from 280 parts per million to 380 parts per million since 1750, and are higher than any level seen in the last 650,000 years. These concentrations could exceed 700 parts per million by 2100leading to an increase in global average surface temperature of over 11 ºFif current trends in emission growth continue.”
