Scientists claim to have the "proof" that global warming is a man-made phenomenon.
"Tim Barnett, a marine physicist at the Scripps Institution of Oceanography in San Diego and a leading member of the team...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."
