The Final Proof: Global Warming is a Man-Made Disaster 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 skeptics 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."
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."
