Wikipedia has good information on Climate Change (or lack there of)
Climate change denial is a set of organized attempts to downplay, deny or dismiss the scientific consensus on the extent of global warming, its significance, and its connection to human behavior, especially for commercial or ideological reasons. Typically, these attempts take the rhetorical form of legitimate scientific debate, while not adhering to the actual principles of that debate. Climate change denial has been associated with the fossil fuels lobby, the Koch brothers, industry advocates and free market think tanks, often in the United States. Some commentators describe climate change denial as a particular form of denialism.
