KODIAK ISLAND, Alaska, August 24, 2009 (ENS) – Billions of tons of carbon are buried in the frozen Arctic tundra, now heating up because of human-caused climate change. To measure which greenhouse gases are being released and in what quantities, government scientists are flying instrument-laden planes over the tundra from now through November. They say […]
Sonar survey spies mysterious, 1.4-kilometer-tall feature in the depths off California By Sid PerkinsAn oceanographic survey has discovered a 1,400-meter-tall plume rising from the seafloor off the coast of California. Water samples taken at the site, about 32 kilometers northwest of Cape Mendocino, indicate that the feature isn’t mineral-rich water spewing from a hydrothermal vent, […]
The warming of an Arctic current over the last 30 years has triggered the release of methane, a potent greenhouse gas, from methane hydrate stored in the sediment beneath the seabed. Scientists at the National Oceanography Centre Southampton working in collaboration with researchers from the University of Birmingham, Royal Holloway London and IFM-Geomar in Germany […]
WASHINGTON, DC, April 21, 2009 (ENS) – Atmospheric concentrations of two of the most potent global warming gases rose last year, according to a preliminary analysis for the annual greenhouse gas index compiled by the U.S. National Oceanic and Atmospheric Administration, NOAA, which tracks data from 60 sites around the world. At the end of […]
by Fred Pearce, environment correspondent for New Scientist “I AM shocked, truly shocked,” says Katey Walter, an ecologist at the University of Alaska in Fairbanks. “I was in Siberia a few weeks ago, and I am now just back in from the field in Alaska. The permafrost is melting fast all over the Arctic, lakes […]
ScienceDaily (Dec. 18, 2008) — A team led by International Arctic Research Center scientist Igor Semiletov has found data to suggest that the carbon pool beneath the Arctic Ocean is leaking. The results of more than 1,000 measurements of dissolved methane in the surface water from the East Siberian Arctic Shelf this summer as part […]
GENEVA (Reuters) – Gases blamed for global warming reached record levels in the atmosphere last year, the United Nations weather agency said on Tuesday. Concentrations of carbon dioxide (CO2) and nitrous oxide (N2O) touched new highs after more steady rises in 2007, and methane had its largest annual increase in a decade, the World Meteorological […]
