University of Alaska Fairbanks The seafloor off the coast of Northern Siberia is releasing more than twice the amount of methane as previously estimated, according to new research results published in the Nov. 24 edition of the journal Nature Geoscience. The East Siberian Arctic Shelf is venting at least 17 teragrams of the methane into the atmosphere each year. A teragram is equal to 1 million tons. “It is now on par with the methane being released from the arctic tundra, which is...

Scientists at the Department of Energy's Oak Ridge National Laboratory are planning a large-scale, long-term ecosystem experiment to test the effects of global warming on the icy layers of arctic permafrost. While ORNL researchers have conducted extensive studies on the impact of climate change in temperate regions like East Tennessee, less is known about the impact global warming could have on arctic regions. "We're beginning to take these lessons learned and start applying them to sensitive...

Two University of the Alaska Fairbanks researchers are among key contributors to a new national report that details visible effects of climate change in the United States and how today's choices stand to affect the future.The report, "Global Climate Change Impacts in the United States," is the first to focus on observed and projected climate change and its effects specifically in the United States. UAF scientists A. David McGuire and John Walsh were part of a consortium of experts from 13...

What better way to engage students in science than to apply lessons learned from fieldwork? This is the philosophy of Alaska teachers participating in the Arctic Expedition for K-12 Teachers, a program organized by the International Arctic Research Center (IARC) at the University of Alaska Fairbanks and a handful of international agencies. For 33 days teachers from Alaska, Canada, France, Germany, Russia, Sweden and England will take atmospheric measurements, collect ice cores, install ice...

ANCHORAGE, Alaska -- Arctic lakes are shrinking, and melting permafrost brought on by higher temperatures may be the reason, according to a research paper. California, Alaska and New York researchers compared satellite images spanning 30 years of more than 10,000 large lakes over 200,000 square miles in Siberia. They concluded that lakes where permafrost remains frozen are growing. But where permafrost has thinned or completely melted, lakes are shrinking or disappearing, a change that...
