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 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 and a leading member of the team, 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?"
The findings are crucial because much of the evidence of a warmer world has until now been from air temperatures, but it is the oceans that are the driving force behind the Earth's climate. Dr Barnett said: "Over the past 40 years there has been considerable warming of the planetary system and approximately 90 per cent of that warming has gone directly into the oceans."
