Their studies strengthen the theory that a warmer climate heats the ocean surface and fuels massive storms.

Kevin Trenbeth, a climate scientist at the National Center for Atmospheric Research in Boulder, Colo., said the study didn't account for changes in sea surface temperatures, which are the main drivers of changes in the position of the rain belts (as is seen during an El Nino event, when Pacific warming pushes the subtropical jet over the Western U.S. southward).

The study marks the first time that human influence on the climate has been demonstrated in the water cycle, and outside the bounds of typical physical responses such as warming deep ocean and sea surface temperatures or diminishing sea ice and snow cover extent.

«Such a slowdown is consistent with the projected effects of anthropogenic climate change, where warming and freshening of the surface ocean from melting ice caps leads to weaker overturning circulation,» DeVries explained.

The study stops short of attributing California's latest drought to changes in Arctic sea ice, partly because there are other phenomena that play a role, like warm sea surface temperatures and changes to the Pacific Decadal Oscillation, an atmospheric climate pattern that typically shifts every 20 to 30 years.

But the change from 2004 to 2007 in the sun's output of visible light, and the attendant warming at Earth's surface of 0.1 watt per square meter, is roughly equivalent to the overall forcing of the sun on the climate over the past 25 years — estimated by the U.N. Intergovernmental Panel on Climate Change to be an additional 0.12 watt per squareclimate over the past 25 years — estimated by the U.N. Intergovernmental Panel on Climate Change to be an additional 0.12 watt per squareClimate Change to be an additional 0.12 watt per square meter.
