Anthropogenic global warming refers to that portion of global warming attributed to human activity, specifically the introduction of greenhouse gases into the atmosphere. Atmosphere scientists are divided on how much of the 20th century's 0.6 degree centigrade warming was caused by human activity. See global warming controversy.
Despite the general agreement that temperatures have risen in the last century (somewhere between 0.4 and 0.8C), the proportion of this warming that is due to human influence is still an open to question is. Most climate scientists recognize that the Little Ice Age, a cold period, ended recently and of course warming happens at the end of a cold period.
A summary of climate research may be found in the IPCC assessment reports, though it is difficult for the layperson to assess which sources should be believed.
More is available from the global warming page.
The UN created the Intergovernmental Panel on Climate Change, an organization which aims to be objective, but its opponents assert that it has misrepresented scientific reports because of political pressure. The IPCC says its role is to assess on a comprehensive, objective, open and transparent basis the scientific, technical and socio-economic information relevant to understanding the scientific basis of risk of human-induced climate change, its potential impacts and options for adaptation and mitigation.
SEPP, an organization which claims to be non-partisan, presents a number of objections to interpretation of the available data on global warming. In particular, they point out that temperature measurements from weather balloons show no warming whatsoever in the 1979 to 1996 period when land-based thermometers show record-breaking rises (they won't tell you that the longer-term balloon record from 1958 matches the land-based record well). Also, they present evidence that rising temperatures cause sea level to fall (not rise, as orthodox global warming theory predicts) although this is widely disbelieved. However, the oil corporation ExxonMobil is one of SEPP's sponsors.
Political aspects
Internationally, political debate has been going on about the possibility to reduce the emission of greenhouse gases. This led to the Kyoto protocol.
The U.S. Democratic Party considers anthropogenic global warming to be a well-established danger to humanity. Many conservatives in the U.S. believe that the dangers of anthropogenic global warming is highly exaggerated. Among them is President Bush.
