The anthropogenic global warming theory holds human beings responsible for most of the slight warming trend seen since the Little Ice Age.
A panel of the United Nations is "90% sure" that most global warming since about 1950 has been caused by human beings.[1] But Roger Pielke, Professor of Environmental Studies at the University of Colorado, said, "After Climategate, the surface temperature record is being called into question." To experts such as McIntyre and Pielke, perhaps the most baffling thing has been the near-unanimity over global warming in the world’s mainstream media - a unanimity much greater than that found among scientists.[2]
The idea that human activities, such as the combustion of fossil fuels, can significantly warm the earth's atmosphere is called the enhanced greenhouse effect.[3]
Terminology
The term "anthropogenic" comes from Anthropo- ("men") and genic (cause).
Relation to current climate change
The anthropogenic global warming theory is one of several explanations for the 1.5 degrees F of warming[4] of the earth's surface recorded since the middle of the 19th century.
The theory enjoys broad based political support from Liberals, Greens and the US Democratic Party, and theory supporters frequently assert the existence of a "scientific consensus" favoring their viewpoint (see Politics of global warming).
