Lee Rannals for redOrbit.com — Your Universe Online More evidence is pointing to the nightmare scenario that global warming is taking a toll on our planet. Oxford University scientists say that a global temperature rise of 2.7 degrees Fahrenheit could thaw the ground over a large area of Siberia, threatening the release of carbon from soil. If the thawing of Siberia's permafrost occurs, it could see that over 1,000 gigatons of the greenhouse gases carbon dioxide and methane are...

Arctic Permafrost Melt Releasing Carbon Dioxide At Unprecedented Rate

Lawrence LeBlond for redOrbit.com - Your Universe Online Editor's note (Feb 16): This story earlier reported that thermokarst failures were occurring do to permafrost melt. However, permafrost doesn't melt, it thaws. The changes have been made to this story to reflect that. Researchers studying Arctic thermokarst failures in Alaska were alarmed to find climate-warming carbon dioxide gas may be releasing into the atmosphere at an unprecedented rate. This release is being caused by...

The thousands of oval lakes that dot Alaska's North Slope are some of the fastest-growing lakes on the planet. Ranging in size from puddles to more than 15 miles in length, the lakes have expanded at rates up to 15 feet per year, year in and year out for thousands of years. The lakes are shaped like elongated eggs with the skinny ends pointing northwest. How the lakes grow so fast, why they're oriented in the same direction and what gives them their odd shape has puzzled geologists for...
