[global warming] fact or myth – does the epa care

1] The Stern Report was set upon by many bloggers and dismantled but did they dismantle the report or the phenomenon of climate change as well? Is anyone saying there’s no climate change?

How much of this do you dispute? Greenhouse gases are generated naturally and by human activities, including the burning of fossil fuels. Once in the atmosphere, they trap the sun's heat and radiate it back to Earth. Motor vehicles emit four major greenhouse gases: carbon dioxide, methane, nitrous oxide and hydrofluorocarbons.

Whose side are you on here? California is part of a coalition of 12 states and environmental groups imploring the Supreme Court to tell the Bush administration that its Environmental Protection Agency has the authority and responsibility to regulate greenhouse gases emitted by new cars. The EPA has balked for years, saying the Clean Air Act does not allow it to step in.

The EPA's approach has frustrated environmentalists and the majority of climate scientists, who say rising levels of greenhouse gases are the driving force behind global warming. The Bush administration contends that it does not have the power to regulate greenhouse gases, and that even if it did, it would not exercise it. The government says carbon dioxide and other greenhouse gases are not “air pollutants” as the Clean Air Act defines them.

To oversimplify, Arnie says there’s global warming and that the cause and the course are clear. Dubya says there’s not and that they are not.

2] Or there is an alternative explanation. What about this and this being the real causes?
