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…

New Findings Back Snowball Earth Theory
05.03.2010
Reporting their findings in the journal Science, a team of geologists led by scientists from Harvard University has found evidence of sea ice reaching until the equator some 716.5 million years ago, adding new elements to support the snowball Earth theory, which theorizes that the Earth has in the past…

Widely Distributed Debris in Antarctica Points to Airburst Event Long Ago
04.03.2010
The results of new research presented at the Lunar and Planetary Science Conference (LPSC) in The Woodlands, Texas show that a large rock from space might have exploded over Antarctica thousands of years ago. The object, which probably weighed some 100,000 tons, is thought to have exploded in the Earth’s…

Can Polar Bears Survive Rapid Change in Climate Again?
04.03.2010
A team of scientists was able to determine that the polar bear is a relatively new species that rapidly adapted at a time when the Earth was beginning to warm at the end of an ice age, according to a new study published in the Proceedings of the National Academy…

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…
