温室气体是指大气中自然或人为产生的的气体成分,它们能够吸收和释放地球表面、大气和云发出的热红外辐射光谱内特定波长的辐射。该特性导致温室效应。

The Environmental Protection Agency is expected to act for the first time to regulate carbon dioxide and other greenhouse gases that scientists blame for the warming of the planet, according to top Obama administration officials.

The decision, which most likely would play out in stages over a period of months, would have a profound impact on transportation, manufacturing costs and how utilities generate power. It could accelerate the progress of energy and climate change legislation in Congress and form a basis for the United States' negotiating position at United Nations climate talks set for December in Copenhagen.

The environmental agency is under order from the Supreme Court to make a determination whether carbon dioxide is a pollutant that endangers public health and welfare, an order that the Bush administration essentially ignored despite near-unanimous belief among agency experts that research points inexorably to such a finding.
