WASHINGTON -- Scientists need a more detailed understanding of how human-produced atmospheric particles, called aerosols, affect climate in order to produce better predictions of Earth's future climate, according to a NASA-led report issued by the U.S. Climate Change Science Program on Friday. "Atmospheric Aerosol Properties and Climate Impacts," is the latest in a series of Climate Change Science Program reports that addresses various aspects of the country's highest priority climate...

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...

The National Center for Atmospheric Research (NCAR) and Sun Microsystems, Inc. (NASDAQ:JAVA) today announced the arrival of AMSTAR, a new digital storage library that will preserve and protect valuable scientific data for the next 15 to 20 years. The new system, designed by Sun Microsystems and based on the Sun StorageTek(TM) SL8500 Modular Library, will give NCAR five times its current storage capacity, enabling it to generate increasingly sophisticated computer studies of Earth's climate....

Scientists are hoping to discover new information on how clouds over the Pacific Ocean can affect the global climate and weather systems. The clouds, some greater than the size of the US, refract sunlight back into space and chill the ocean below. The researchers expect to learn about the clouds' properties and if pollution from activities could alter the arrangement of these cloud systems. The study will engage 200 scientists from 10 countries in the research. An additional team of 20...

Scientists focus on hurricane-prone Gulf of Mexico and Caribbean Sea to assess likely changes Researchers are homing in on the hurricane-prone Gulf of Mexico and Caribbean Sea to assess the likely changes, between now and the middle of the century, in the frequency, intensity, and tracks of these powerful storms. Initial results are expected early next year. The National Center for Atmospheric Research (NCAR) in Boulder, Colo., working with federal agencies as well as the insurance and energy...

The U.S. Department of Energy announced it will make available more than 10 million hours of computing time to study advanced climate change models. The department's Office of Science will allocate the computer time to the National Oceanic and Atmospheric Administration to explore advanced climate change models at three of the department's national laboratories. The project is part of a three-year agreement on collaborative climate research that was signed Monday by the two agencies. NOAA...
