Microbes in streams flowing on the surface of glaciers in the Arctic and Antarctic may represent a previously underestimated source of organic material and be part of an as yet undiscovered "dynamic l...
Study:Alaskan boreal forest fires release more carbon than the trees can absorb
Alaskan boreal forest fires carbon trees
2015/11/12
A new analysis of fire activity in Alaska's Yukon Flats finds that so many forest fires are occurring there that the area has become a net exporter of carbon to the atmosphere. This is worrisome, the ...
When scientists discuss global change, they often focus on the amount of carbon in the atmosphere and vegetation. But soil contains more carbon than air and plants combined. This means that even a min...
