- Campus Health Services has been awarded $300,000 per year in grant funding for the next two years to expand substance abuse prevention and early intervention efforts on campus. The funding was awarded by the Governor’s Office of Youth Faith and Family as part of SAMHSA’s State Targeted Response to… Read more
Scientists who study climate and ecosystems in the Arctic have weighed in on future changes in the region affecting soils, streams and wildfire, which will be releasing greater amounts of carbon dioxide and other greenhouse gases into the atmosphere.
Because the Arctic is home to billions of tons of naturally occurring carbon stored in frozen soil, researchers are turning their focus to trying to quantify potential effects of large-scale permafrost thawing.
As temperatures melt the arctic permafrost, thawing billions of bacteria in the soil, the microbes wake up hungry and begin eating all the carbon in sight, accelerating the release of greenhouse gases into the atmosphere.
These results were published in Nature Climate Change this week, following one of the first field studies of its kind.
Ted Schuur, professor of ecosystem ecology, ran the field study in Alaska and worked collaboratively with a team of researchers.
“We found as soon as the… Read more
As scientists measure the speed and effects of carbon release from thawing Arctic permafrost, one group is studying the metabolism of old carbon that has been stored in soils but is now being released by a warming climate.
Estimates put the amount of carbon stored in soils of the permafrost region to be almost twice the amount present in the atmosphere. Billions of tons of organic carbon from plants and animals have been stored in these frozen soils for hundreds… Read more
