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...

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...

Combination of hi-tech models and paleo-records may hold key to unlocking reason for Anastazi people's migration and other global events In the time before Columbus sailed the ocean blue, a cooler central Pacific Ocean has been connected with drought conditions in Europe and North America that may be responsible for famines and the disappearance of cliff dwelling people in the American West. A new study from the University of Miami (UM) has found a connection between La...

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 climate and...

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...

When it comes to nature, timing is everything. Spring flowers depend on birds and insects for pollination. But if spring-like weather arrives earlier than usual, and flowers bloom and wither before the pollinators appear, the consequences could be devastating for both the plants and the animals that feed on them. Global warming has made the early arrival of spring commonplace across the planet, say climate scientists. Plants are blooming earlier, birds are nesting sooner and mammals are...

The Earth's temperature may be 30-50 percent more sensitive to atmospheric carbon dioxide than has previously been estimated, reports a new study published in Nature Geoscience this week In the long term, the Earth's temperature may be 30-50% more sensitive to atmospheric carbon dioxide than has previously been estimated, reports a new study published in Nature Geoscience this week. The results show that components of the Earth's climate system that vary over long timescales "“ such as...

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...

The composition of some of our nation's forests may be quite different 200 to 400 years from today according to a recent study at the University of Illinois. The study found that temperature and photosynthetic active radiation were the two most important variables in predicting what forest landscapes may look like in the future. The uncertainties became very high after the year 2200. Approximately 100,000 acres of forested area west of Lake Superior which make up the Boundary Waters Canoe...

If you think this summer's U.S. temperatures have been uncomfortably high, scientists say one day your children may view summer 2009 as the cool old days. Researchers at the non-profit organization Climate Central say they reached that conclusion after analyzing current climate change projections made with global climate models. They said scientific literature based on the models anticipates much more frequent occurrences of hot days, heat waves and extremely warm summer seasons. The...
