Changes in the Arctic: Consequences for the World - SpaceDaily  Left:  Declining Arctic ice cover: This image, using NASA satellite data, shows declining Arctic sea ice concentrations (% per decade, shaded) from October 1978 to September 2002. The highest amounts of lost ice are shaded in dark blue. Credit: Georgia Tech. See larger image   Ground-based surface temperature data shows that the rate of warming in the Arctic from 1981 to 2001 is eight times larger than the rate of Arctic warming over the last 100 years. There have also been some remarkable seasonal changes. Arctic spring, summer, and autumn have each warmed, lengthening the seasons when sea ice melts from 10 to 17 days per decade. Arctic sea ice extent and area decreased, respectively, by 30,848 km2/year.
New Radar Provides 3-D Forest View - SpaceDaily  Left:  Radar interferometry to produce Digital Elevation Models - this one showing how a pair of images from twin ERS satellites were used to create one of the Etna volcano in Sicily, Italy. Pairs of images acquired from the same spacecraft during different orbits can also be used. Credits: ESA. More images/captions   An advanced radar technique to image forests in three dimensions has undergone an ESA-backed test campaign in Indonesia. A future space-based version could measure global biomass to sharpen the accuracy of climate change models. "We were able to extract the difference between the tree canopy and the forest floor--and from knowing tree height, we can estimate forest biomass with a reasonable degree of certainty.."

Oregon May Lead Future Of Wave Energy - SpaceDaily   Significant advances in university research and other studies in the past two years are pointing toward Oregon as the possible epicenter of wave energy development in the United States. "The development of wave energy right now is probably 15-20 years behind wind energy, which is just now starting to achieve some optimal production technologies," said Alan Wallace, the co-principal investigator at OSU on these projects, and a professor of electrical engineering. "And just like wind energy, these systems will be more expensive at first, and then the cost will come down and become very competitive," Wallace said. There are some operating systems in Europe, and the theoretical potential of this clean, inexhaustible form of energy is enormous experts estimate that 0.2 percent of the ocean's untapped energy could power the entire world.
