From the White House's statement on the new IPCC report:

"This Summary for Policymakers captures and summarizes the current state of climate science research and will serve as a valuable source of information for policymakers," said Dr. Sharon Hays, the leader of the U.S. delegation at the meeting and Associate Director/Deputy Director for Science at the White House Office of Science and Technology Policy. "It reflects the sizeable and robust body of knowledge regarding the physical science of climate change, including the finding that the Earth is warming and that human activities have very likely caused most of the warming of the last 50 years."

Remember, as recently as last summer, Bush was caught claiming of global warming that "There is a debate over whether it's manmade or naturally caused." Based upon this latest statement, I am willing to credit the White House with now being accepting of the scientific consensus. However, if Bush goes and says something different in another press conference somewhere down the road, he can expect to be legitimately slammed for it. And I, for one, will be watching his future remarks closely.
