Just how the sun's cycles of activity and Earth's atmospheric particles influence our climate is unclear, but NASA's Glory mission should provide some answers. more...
Tiny Antarctic marine creatures first collected by British explorer Robert Falcon Scott in 1901 may help scientists understand future climate change. (Scientific American/Reuters) more...
Police report multiple fatalities in a city still recovering from a 7.0 magnitude earthquake in Sept. 2010. (Discovery News) more...
Average Arctic temperatures have risen by 2 degrees Celsius in recent years, melting soil that had been frozen for millennia, and that means both mealtime for microbes—and bad news for climate change. (Scientific American) more...
Future climate change could change the shape of tropical forests, with possible consequences for carbon storage and biodiversity, a study says. (BBC News) more...
Scientists developed a new technique that removes the bias in wind observations over Earth's oceans and found that during the last 60 years the tropical Atlantic trade winds weakened, ocean temperature patterns shifted, and Amazon and Guinea Coast rainfall increased. (University of Hawaii at Manoa) more...
A new, detailed record of rainfall fluctuations in ancient Mexico that spans more than twelve centuries promises to improve our understanding of the role drought played in the rise and fall of pre-Hispanic civilizations. (American Geophysical Union) more...
New discoveries on how underwater ridges impact the ocean's circulation system will help improve climate projections, according to scientists who looked back three million years and studied the influence of the North Atlantic Ocean's Greenland-Scotland Ridge on surface water temperature. (U.S. Geological Survey) more...
New research shows that the 2010 Amazon drought may have been even more devastating to the region's rainforests than the unusual 2005 drought, which was previously billed as a one-in-100 year event. (University of Leeds) more...
