'''Global Warming''' is the controversial theory that the earth's atmosphere is heating up at a dangerous rate, because of human activities such as [[greenhouse gas]] emissions from burning [[fossil fuels]]. Supporters usually feel that immediate (not to say drastic) action must be taken to reduce these omissions (see [[Kyoto Protocol]]).  

The '''global warming controversy''' centers on the controversial theory that the earth's atmosphere is heating up at a dangerous rate, because of human activities such as [[greenhouse gas]] emissions from burning [[fossil fuels]] (see [[Anthropogenic global warming]]). Supporters usually feel that immediate (not to say drastic) action must be taken to reduce these omissions (see [[Kyoto Protocol]]).  

The theory enjoys wide political support, but many climatologists and meteorologists disagree with it. The United Nations' climate panel ([[UNIPCC]]) has assessed the theory and found that there is a "scientific consensus" in favor of it. Scientists [[Richard Lindzen]] and John Christy, among others,  deny that such a consensus exists.
