Hurricane Ike tracked by ESA's Envisat

Residents along the Gulf Coast are bracing for Hurricane Ike as it travels over the Gulf of Mexico after ripping through Cuba and Haiti. ESA's Envisat satellite is tracking the storm, which is forecast to make landfall on the Texas coast by 13 September.

AGI publishes transition document for next US administration

Alexandria, VA – The American Geological Institute (AGI), in conjunction with its Member Societies, is announcing the release of "Critical Needs for the Twenty First Century: The Role of the Geosciences." This concise document suggests policy directions for the next President, his administration, federal agencies and the United States Congress. The document identifies seven national issues and the role geosciences can play in addressing them: energy and climate, water, waste disposal, natural hazards, infrastructure, raw materials, and workforce and education needs.

NASA study illustrates how global peak oil could impact climate

The burning of fossil fuels -- notably coal, oil and gas -- has accounted for about 80 percent of the rise of atmospheric carbon dioxide since the pre-industrial era. Now, NASA researchers have identified feasible emission scenarios that could keep carbon dioxide below levels that some scientists have called dangerous for climate.

May 2008 earthquake in China could be followed by another significant rupture

Researchers analyzing the May 2008 Wenchuan earthquake in China's Sichuan province have found that geological stress has significantly increased on three major fault systems in the region. The magnitude 7.9 quake on May 12 has brought several nearby faults closer to failure and could trigger another major earthquake in the region.

Old growth forests are valuable carbon sinks

CORVALLIS, Ore. – Contrary to 40 years of conventional wisdom, a new analysis to be published Friday in the journal Nature suggests that old growth forests are usually "carbon sinks" - they continue to absorb carbon dioxide from the atmosphere and mitigate climate change for centuries.

University of Miami scientist uncovers miscalculation in geological undersea record

Report reveals communication needs, recreation use during fires

The effectiveness of the media to inform the public during evacuations and wildland fire effects on recreation are some topics addressed in a U.S. Forest Service report published this month that is a compilation of 17 studies on the social science aspects of fires.

More than 20 scientists present their work in the 260-page report, entitled "Fire Social Science Research From the Pacific Southwest Research Station: Studies Supported by National Fire Plan Funds."

Food soil stuck to surfaces can hold bacteria in food processing factories

Tiny amounts of food soil stuck to surfaces can act as a reservoir for potentially pathogenic bacteria. This food may help bacteria to survive industrial cleaning regimes in food processing factories, scientists heard today (Wednesday 10 September 2008) at the Society for General Microbiology's Autumn meeting being held this week at Trinity College, Dublin.

Copper-bottomed guarantee for safe shellfish in restaurants

Putting brass where your money is could be a guarantee of safety according to researchers looking at the dangers of eating raw fish and shellfish in seafood restaurants, scientists heard today (Wednesday 10 September 2008) at the Society for General Microbiology's Autumn meeting being held this week at Trinity College, Dublin.

Silent streams? Escalating endangerment for North American freshwater fish

Nearly 40 percent of fish species in North American streams, rivers and lakes are now in jeopardy, according to the most detailed evaluation of the conservation status of freshwater fishes in the last 20 years.

The 700 fishes now listed represent a staggering 92 percent increase over the 364 listed as "imperiled" in the previous 1989 study published by the American Fisheries Society. Researchers classified each of the 700 fishes listed as either vulnerable (230), threatened (190), or endangered (280). In addition, 61 fishes are presumed extinct.
