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...

If you are wilting under the summer heat, consider this: your child may one day think of summer 2009 as "back in the cool old days." To illustrate expected increases in extreme summer heat, scientists at Climate Central have analyzed climate change projections made with global climate models.Scientific literature based on these models anticipates much more frequent occurrences of hot days, "heat waves" (very high temperatures sustained over several days), and extremely warm summer seasons....

Does ozone have an impact on the ocean's role as a "carbon sink"? Yes, according to researchers from three laboratories (1) attached to INSU-CNRS (2), UPMC, CEA, IRD, MNHN and UVSQ. Using original simulations, they have demonstrated that the hole in the ozone layer reduces atmospheric carbon uptake in the Southern Ocean and contributes to the increase in ocean acidity. These results, which are published online in the journal Geophysical Research Letters, should have a considerable impact on...


Word of the Day
mallemaroking
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
