SAN FRANCISCO CHRONICLE Ocean tells the story: Earth is heating up Human activity, not variables in nature, cited as culprit - Carl T. Hall, Chronicle Science Writer Friday, April 29, 2005 New temperature readings from the deep ocean trace a clear warming trend that seems impossible to turn around any time soon, scientists reported Thursday, promising a steadily warming world and raising the odds of a catastrophic sudden change marked by rising seas and melting icecaps. Researchers led by James Hansen, one of NASA's top climatologists, looked at the planet's "energy imbalance" -- the difference between the amount of heat absorbed by Earth and the amount radiated out into space -- and compared those results with predictions of leading climate models. They concluded that the unusual magnitude of the warming trend could not be explained by natural variability, but instead fit precisely in line with theories suggesting that human activity -- the dominant "forcing agent" driving the computerized climate models -- is responsible. "This energy imbalance is the 'smoking gun' that we have been looking for, " Hansen said in a prepared summary of the study, which was published in the journal Science. "The magnitude of the imbalance agrees with what we calculated using known climate forcing agents, which are dominated by increasing human-made greenhouse gases. There can no longer be substantial doubt that human-made gases are the cause of most observed warming." "... "... "... "...
