As recently as last week the Bush administration was still insisting that the Kyoto Protocol on reducing greenhouse gases was based on politics, not science. This is nonsense.
The ever-growing scientific consensus on global warming is clearly expressed in the reports of the Intergovernmental Panel on Climate Change. The American Meteorological Society, the American Geophysical Union, and the American Association for the Advancement of Science have all issued statements asserting that the evidence is compelling for human modification of climate.
There is room for honest disagreement on what to do about global warming, but to suggest that the scientific community is divided on the reality of human-induced climate change is disingenuous. The concensus may not be universal, but it is overwhelmingly lolpsided.
