Prometheus 6

Think again.

Mrs. Merkel’s environmental minister, Sigmar Gabriel, warned that Mr. Bush’s plan might prove to be a “Trojan horse,” impeding her efforts to reach an agreement on an ambitious plan to decrease emissions, while defusing criticism that the United States is a hurdle to the broader climate effort....

Critics also contend that Mr. Bush’s proposal to seek a global deal by the end of 2008 would undermine the role of the United Nations as the main forum for climate negotiations, including the talks that led to the Kyoto Protocol, which required participating industrialized nations to reduce emissions. Convening the largest emitters in the United States would create a parallel round of talks, they said.

Bush hasn't changed a policy since 2001. Not one (Iraq doesn't count because that was taken away from him). His administration has altered scientific reports to the point of falsification and insisted they were objective. There is absolutely no reason to believe him sincere at any point prior to the actual manifestation of his promises.
