Arctic Sea Ice Declines Again This Year Finds Study - SpaceDaily  Researchers at the University of Colorado at Boulder have found that the extent of Arctic sea ice- the floating mass of ice that covers the Arctic Ocean- is continuing its rapid decline. The latest satellite information indicates the September 2004 sea ice extent was 13.4 percent below average, a reduction in area nearly twice the size of Texas, said Mark Serreze of CU-Boulder's National Snow and Ice Data Center, or NSIDC. In 2002, the decline in arctic sea ice during September - which traditionally marks the end of the summer melt season - was about 15 percent, a record low, said CU-Boulder researcher Walt Meier of NSIDC. The decline in sea ice extent during September has averaged about 8 percent over the past decade, said Serreze, who is part of a CU-Boulder team monitoring Arctic sea-ice conditions. "This is the third year in a row with extreme ice losses, pointing to an acceleration of the downward trend," he said. "While a 'low' September ice extent one year is often followed by a recovery the next year, this was not the case in 2003, which was about 12 percent below average," Serreze said. "Climate models are in general agreement that one of the strongest signals of greenhouse warming will be a loss of Arctic sea ice," he said. "Some indicate complete disappearance of the summer sea ice cover by 2070." Serreze believes natural climate variability likely plays some part in the observed changes.
Earthquake Forecast Program Has Amazing Success Rate - SpaceDaily  Left: This is a collapsed section of the Cypress viaduct of Interstate 880 in Oakland, from the Loma Prieta California, Earthquake October 17, 1989. Credit: USGS, H.G. Wilshire   A NASA funded earthquake prediction program has an amazing track record. Published in 2002, the Rundle-Tiampo Forecast has accurately predicted the locations of 15 of California's 16 largest earthquakes this decade, including last week's tremors. "We're nearly batting a thousand, and that's a powerful validation of the promise this forecasting technique holds," Rundle said.

Starbursts Sterilize Center Of Milky Way - SpaceDaily  Left:  Say goodbye to the neighborhood! On this hypothetical world near the center of the Milky Way, the planet's sun paints the sky purple as it descends below the horizon off the left edge of the frame. However, the bright supernova exploding at upper right lends an ominous feeling because its radiation is about to wipe out the alien life on this world. The galactic center is so dense with bright, hot stars that several can be seen through the cloudy twilight sky. (David A. Aguilar, CfA)  Life near the center of our galaxy never had a chance. Every 20 million years on average, gas pours into the galactic center and slams together, creating millions of new stars. The more massive stars soon go supernova, exploding violently and blasting the surrounding space with enough energy to sterilize it completely.
