Model Could be Used to Forecast Climate Impacts for Other Fisheries A new climate-population model developed by NOAA scientists to study rising ocean temperatures and fishing rates on one East Coast fish population could also forecast the impact of climate change and fishing on other fisheries. The model is one of the first to directly link a specific fish stock with climate change. In a paper in the March 2010 issue of the journal Ecology Applications published online March 24 by the...

HAMPTON, Va., Dec. 16 /PRNewswire-USNewswire/ -- New measurements from a NASA satellite show a dramatic cooling in the upper atmosphere that correlates with the declining phase of the current solar cycle. For the first time, researchers can show a timely link between the Sun and the climate of Earth's thermosphere, the region above 100 km, an essential step in making accurate predictions of climate change in the high atmosphere.

Daily record high temperatures occurred twice as often as record lows over past decade Spurred by a warming climate, daily record high temperatures occurred twice as often as record lows over the last decade across the continental United States, new research shows. The ratio of record highs to lows is likely to increase dramatically in coming decades if emissions of greenhouse gases continue to climb. Results of the research, by authors at the National Center for Atmospheric Research (NCAR)...

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...
