It is not just the state of California that is bypassing the authority of the US government to take action on global warming.
The mayors of more than 300 cities across the country have signed a Climate Protection Agreement in which they have pledged to meet the emissions-cutting timetable laid down by the Kyoto Protocol - regardless of what the Bush administration decides.
Some of those cities, such as Seattle, which took the lead on drafting and lobbying for the agreement, are bastions of liberal politics and environmentalism, acting out their ideological convictions. Others, though, such as the exclusive Colorado ski resorts Vail and Aspen, are also motivated by a powerful self-interest. If global warming continues unabated, the Rocky Mountain snowpack will melt and there will be no skiing in Vail, Aspen or anywhere else by the end of this century.
Seattle's Mayor, Greg Nickels, proposed the mayors' agreement whenKyoto came into effect at the start of last year. By June 2005, he had 140 signatories, and the number has more than doubled since.
