QUOTE : One consequence, presumably unintended, of America’s failure to ratify the Kyoto Protocol has been the emergence of a not-quite-grassroots movement. In February 2005, Greg Nickels, the mayor of Seattle, began to circulate a set of principles that he called the “U.S. Mayors Climate Protection Agreement.” Within four months, more than a hundred and seventy mayors, representing some thirty-six million people, had signed on, including Mayor Michael Bloomberg of New York; Mayor John Hickenlooper of Denver; and Mayor Manuel Diaz of Miami. Signatories agreed to “strive to meet or beat the Kyoto Protocol targets in their own communities.” At around the same time, officials from New York, New Jersey, Delaware, Connecticut, Massachusetts, Vermont, New Hampshire, Rhode Island, and Maine announced that they had reached a tentative agreement to freeze power plant emissions from their states at current levels and then begin to cut them. Even Governor Arnold Schwarzenegger, the Hummer collector, joined in; an executive order he signed in June 2005 called on California to reduce its greenhouse gas emissions to 2000 levels by 2010 and to 1990 levels by 2020. “I say the debate is over,” Schwarzenegger declared right before signing the order.
