Growing a forest might sound like a good idea to combat global warming, since trees draw carbon dioxide from the air and release cool water from their leaves. But they also absorb sunlight, warming the air in the process. According to a new study from the Carnegie Institution’s Department of Global Ecology and Lawrence Livermore National Laboratory, planting forests at certain latitudes could make the Earth warmer. Carnegie’s Ken Caldeira will present the work at the American Geophysical Union Fal

Glacier has shrunk by nine miles, now at midpoint of retreat

Alaska’s rapidly disintegrating Columbia Glacier, which has shrunk in length by 9 miles since 1980, has reached the mid-point of its projected retreat, according to a new University of Colorado at Boulder study.

Tad Pfeffer, associate director of CU-Boulder’s Institute of Arctic and Alpine Research, said the glacier is now discharging nearly 2 cubic miles of ice annually into the Prince William Sound,

Ohio State University scientists have used minute fluctuations in gravity to produce the best map yet of ocean tides that flow beneath two large Antarctic ice shelves.

They did it using the twin satellites of the Gravity Recovery and Climate Experiment (GRACE), a joint project of NASA and the German Aerospace Center.

Large tides flow along the ocean floor beneath the Larsen and Filchner-Ronne Ice Shelves. Though scientists have long known of these tides, they have not

Product and system prototyping can be as sophisticated and complex as the final products they seek to model. But to model the capabilities of advanced factories and sophisticated vehicles calls for the tools developed by European researchers.

The FLEXICON project addressed the need to reduce the timescales required for producing open and distributed fault-tolerant control and monitoring systems. It developed two integrated suites of tools to support the different development p

Almost a century after the 1906 earthquake, Stanford geophysicists have revisited San Francisco’s ’’Big One’’ and now paint a new picture of a fault that was ready to go and that ruptured farther and faster than previously supposed.

“Our understanding of seismic hazard in Northern California, including the Bay Area, relies on a thorough understanding of this earthquake and the San Andreas Fault,” said Professor Gregory C. Beroza, who with graduate student

As the future of Earth’s forests moved up the agenda at the United Nations Climate Change Conference – negotiating a post-Kyoto strategy to combat global warming – ESA and its national collaborators presented delegates with promising results from projects using satellites to identify wide-area forest retreat and expansion.

The planet’s climate is moving into uncharted territory, as our burning of fossil-fuels and clearances of forests release massive amounts of heat-trapping
