ORNL researchers contribute to State Department's Arctic blog

ORNL's Peter Thornton, Stan Wullschleger and Kate Evans have written an entry for the State Department's "Our Arctic Nation" blog on Medium.com. The blog, run by the Arctic Council of the State Department's Office of Oceans and Polar Affairs, invites individuals with personal or professional connection to the Arctic to contribute to raise awareness of U.S. interests and priorities in the region and reinforce the idea of the United States as an Arctic nation

Finding the human fingerprint in Northern Hemisphere greening

Using newer data and strict statistical methods, a multinational team led by the Oak Ridge National Laboratory Climate Change Science Institute’s (CCSI’s) Jiafu Mao has found the first positive correlation between human activities and enhanced vegetation growth in the northern extratropical latitudes (NELs; roughly between 30°N and 75°N). “This is the first clear evidence of a discernible human fingerprint on physiological vegetation changes at the continental scale,” Mao says.

Drying Arctic soils could accelerate greenhouse gas emissions

OAK RIDGE, Tenn., June 13, 2016—A new study published in Nature Climate Change indicates soil moisture levels will determine how much carbon is released to the atmosphere as rising temperatures thaw Arctic lands. An international team led by Northern Arizona University scientists analyzed the results of 25 experiments from multiple research groups including the Department of Energy’s Oak Ridge National Laboratory. The researchers had measured the release of greenhouse gases from incubated soil samples, which originated in field sites in Alaska, Canada and Russia, under a temperature increase of 10 degrees Celsius.
