Once again, facts seem to be conspiring against the Bush administration:
Scientists have found the first unequivocal link between man-made greenhouse gases and a dramatic heating of the Earth's oceans.
The researchers - many funded by the US government - have seen what they describe as a "stunning" correlation between a rise in ocean temperature over the past 40 years and pollution of the atmosphere.
The study destroys a central argument of global warming sceptics within the Bush administration - that climate change could be a natural phenomenon. It should convince US president George Bush to drop his objections to the Kyoto treaty on climate change, the scientists say.
Tim Barnett, a marine physicist at the Scripps Institution of Oceanography in San Diego, said: "We've got a serious problem. The debate is no longer: 'Is there a global warming signal?' The debate now is: 'What are we going to do about it?'"
He told the American Association for the Advancement of Science in Washington: "We defined a 'fingerprint' of ocean warming. Each of the oceans warmed differently at different depths and constitutes a fingerprint which you can look for. We had several computer simulations, for instance one for natural variability: could the climate system just do this on its own? The answer was no.
"We looked at the possibility that solar changes or volcanic effects could have caused the warming - not a chance. What just absolutely nailed it was greenhouse warming."
This is probably getting annoying by now, but: Why does science hate America?
