For the first time, climate scientists from across the country have successfully incorporated the nitrogen cycle into global simulations for climate change, questioning previous assumptions regarding carbon feedback and potentially helping to refine model forecasts about global warming. The results of the experiment at the Department of Energy's Oak Ridge National Laboratory and at the National Center for Atmospheric Research are published in the current issue of Biogeosciences. They...

GREENBELT, Md., Aug. 24 /PRNewswire-USNewswire/ -- NASA's Goddard Space Flight Center in Greenbelt, Md., made available to scientists in August the first unit of an expanded high-end computing system that will serve as the centerpiece of a new climate simulation capability. The larger computer, part of NASA's High-End Computing Program, will be hosting the agency's modeling contributions to the Intergovernmental Panel on Climate Change (IPCC) and other national and international climate...

The role of clouds in climate change has been a major question for decades. As the earth warms under increasing greenhouse gases, it is not known whether clouds will dissipate, letting in more of the sun's heat energy and making the earth warm even faster, or whether cloud cover will increase, blocking the Sun's rays and actually slowing down global warming.In a study published in the July 24 issue of Science, researchers Amy Clement and Robert Burgman from the University of Miami's...

Researchers trace a problem with a key climate model to its hyrdrology scheme and find a simpler scheme keeps simulations in line with real-world observations Imagine a climate model as a black box. You put something in, you get something out. But what happens when the output is completely unexpected? "If you don't get the results you expect, that's when you start to ask why," said climate modeler Peter Lawrence from the University of Colorado at Boulder's Cooperative Institute for Research...

The frequency of extremely high clouds in Earth's tropics -- the type associated with severe storms and rainfall -- is increasing as a result of global warming, according to a study by scientists at NASA's Jet Propulsion Laboratory, Pasadena, Calif. In a presentation yesterday to the fall meeting of the American Geophysical Union in San Francisco, JPL Senior Research Scientist Hartmut Aumann outlined the results of a study based on five years of data from the Atmospheric Infrared Sounder...

Future increases in wind strength along the California coast may have far-reaching effects, including more intense upwelling of cold water along the coast early in the season and increased fire danger in Southern California, according to researchers at the Climate Change and Impacts Laboratory at the University of California, Santa Cruz. Earth scientist Mark Snyder presented the findings in a poster titled "Future Changes in Surface Winds in the Western U.S. due to Climate Change" at the Fall...

Rising Seas, Severe Drought, Could Come in Decades, Says U.S. Report The United States could suffer the effects of abrupt climate changes within decades "” sooner than some previously thought - says a new government report. It contends that seas could rise rapidly if melting of polar ice continues to outrun recent projections, and that an ongoing drought in the U.S. west could be the start of permanent drying for the region. Commissioned by the U.S. Climate Change Science Program, the...
