The '''global Global warming controversy''' centers on the controversial theory fact 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.
The name is inaccurate, and should be '''Global Climate Change''', as the increasing amount of heat stored in the atmosphere has had disruptive effects leading to colder weather in some areas.
