Latest Climate model Stories

Scientists at the Carnegie Institution's Department of Global Ecology have taken a new approach on examining a proposal to fix the warming planet. So-called geoengineering ideas"”large-scale projects to change the Earth's climate"”have included erecting giant mirrors in space to reflect solar radiation, injecting aerosols of sulfate into the stratosphere making a global sunshade, and much more. Past modeling of the sulfate idea looked at how the stratospheric aerosols might affect Earth's...

Scientists can now study climate change in far more detail with powerful new computer software released by the National Center for Atmospheric Research (NCAR).The Community Earth System Model (CESM) will be one of the primary climate models used for the next assessment by the Intergovernmental Panel on Climate Change (IPCC). The CESM is the latest in a series of NCAR-based global models developed over the last 30 years. The models are jointly supported by the Department of Energy (DOE) and...

Greenhouse gases are playing a role in changes, say scientistsNewly detected rising sea levels in parts of the Indian Ocean, including the coastlines of the Bay of Bengal, the Arabian Sea, Sri Lanka, Sumatra and Java, appear to be at least partly a result of human-induced increases of atmospheric greenhouse gases, says a study led by the University of Colorado at Boulder.The study, which combined sea surface measurements going back to the 1960s and satellite observations, indicates...

NASA's Goddard Space Flight Center in Greenbelt, Md. recently introduced the NASA Center for Climate Simulation (NCCS), an integrated set of supercomputing, visualization, and data interaction technologies that will enhance agency capabilities in weather and climate prediction research."The NASA Center for Climate Simulation has been designed to meet the unique computational needs of the climate modeling community supported by NASA's Earth Science Division," said Phil Webster, chief...

Debuting in spring 2010, the NASA Center for Climate Simulation (NCCS) is the new name for a Goddard Space Flight Center organization that has provided supercomputing resources to NASA scientists and engineers for over 25 years."Computation here at Goddard is primarily to create datasets and make them available for science researchers around the world," said Phil Webster, chief of Goddard's Computational and Information Sciences and Technology Office, which includes NCCS. With...

NSF-supported climate scientist Mark Flanner and colleagues find differences in the rates for spring warming and snow cover decline in Eurasia and North America, and are studying whether aerosols are a key factorOver the past 30 years, springtime snow melt and warming appear to be proceeding at a faster rate in Eurasia than in North America.Climate scientist Mark Flanner, an assistant professor at the University of Michigan and a recent Advanced Study Program graduate at the National Science...

Model Could be Used to Forecast Climate Impacts for Other FisheriesA 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 decadeSpurred 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) in...
