Ocean Warming -- The Smoking Gun of Global Warming

New precise measurements of the accumulation of heat in the earth's ocean confirm that heat-trapping pollution is the primary cause of global warming. Two research teams, led by scientists at the Scripps Institution for Oceanography and NASA's Goddard Institute for Space Studies, reached the same conclusion independently. Their measurements show that not only are the earth's land and ocean surfaces warming, but that the heating has penetrated more than 1,000 feet into the oceans' depth. These observations clear away any question of whether the warming trend seen in surface readings could be a spurious result of changes in land use and weather station locations. They can only be explained as the result of the thickening blanket of heat-trapping pollution in the atmosphere, which causes the earth to retain excess energy from the sun. The NASA group quantified this energy imbalance and found that it closely matched the imbalance predicted by their climate model. "This energy imbalance is the 'smoking gun' that we have been looking for" according to Jim Hansen, director of the NASA Goddard Institute for Space Studies and the lead author of one of the studies.
