Lord May, president of Britain’s Royal Society, said in releasing the statement that U.S. President George W. Bush’s policy on climate change was “misguided” and ignored scientific evidence.

The statement called on the G-8 nations to “recognize that delayed action will increase the risk of adverse environmental effects and will likely incur a greater cost.”

“The Bush administration has consistently refused to accept the advice of the U.S. National Academy of Sciences. The NAS concluded in 1992 that, ‘Despite the great uncertainties, greenhouse warming is a potential threat sufficient to justify action now,’ by reducing emissions of greenhouse gases.

He noted that the statement was endorsed by science academies of Brazil, China and India — nations “who are among the largest emitters of greenhouse gases in the developing world.”

“The current U.S. policy on climate change is misguided,” May added.
