Stores of Methane in Arctic Seabed Being Released into Atmosphere
08.03.2010
New results from an international study published in the journal Science show that the permafrost under the East Siberian Arctic Shelf is perforated and releasing huge amounts of methane, a powerful greenhouse gas, into the atmosphere. Three times as large as the Siberian wetlands, the East Siberian Arctic Shelf is…

Glacier Ice Loss in Alaska Overestimated; Rate Nonetheless Doubled over Past 40 Years
04.03.2010
According to a new study featured in Nature Geoscience that recalculates glacier melt in Alaska, previous studies might have largely overestimated mass loss from Alaskan glaciers over the past 40 years. The study shows that Alaskan glacier melts between 1962 and 2006 actually contributed about one-third less to sea-level rise…
