The article reports on the challenges faced by U.S. President George W. Bush and his administration with the climate-change policy in the U.S. There is an argument that the Environmental Protection Agency should be forced to regulate greenhouse-gas emissions from cars and trucks as a pollutant. The problem is that climate change is a large and global problem that the emission in question may not make a huge difference by themselves.

The non-participation of the United States in the recently ratified Kyoto Protocol is a matter for global concern because it is estimated that the country produces 24% of all greenhouse-gas emissions worldwide. Here we analyse the commitment of individual states and municipalities to addressing this problem and find that, despite the federal policy, between 24 and 35% of the US population are currently (or soon will be) engaged in policies directed towards significantly reducing anthropogenic climate change. The importance of this sub-national effort, which we estimate corresponds to 27–49% of the gross domestic product, will depend — like the targets adopted in Kyoto — on the real reductions achieved in greenhouse-gas emissions. [ABSTRACT FROM AUTHOR]

The author reflects on the testimony of Al Gore on climate change in the United States Congress. Gore's recommendations include reducing the emission levels, carbon tax, ban on incandescent light bulbs and new coal plants, corporate disclosure of carbon emissions and mileage standards for cars. The author also discusses the duties of politicians on climate change policy.

The article reports that the latest global meeting on climate change wrapped up in Argentina this week, having made only modest steps towards cutting future greenhouse-gas emissions. Delegates from many nations said that the United States and its allies, such as Saudi Arabia, thwarted progress at the tenth meeting of the Conference of Parties to the UN Framework Convention on Climate Change. During the conference, the United States strongly opposed the idea of using any seminars scheduled between now and next November to jump-start discussions about 2012 and beyond. Environmental groups attacked this position as deliberately obstructive. Saudi Arabia also caused dissent at the meeting,by asking for money from the "adaptation fund" to offset the economic losses it will suffer when petroleum exports are reduced.
