North American cold-climate forests are absorbing less carbon: study

CHICAGO, Aug. 18 (Xinhua) -- A study led by University of Michigan (UM) researchers shows that the amount of carbon Siberian forests contribute to the planet's seasonal carbon flux has increased much more than that of other forests at similar latitudes.

Since the early 1980s, the seasonal carbon uptake in Siberian forests has increased four times more than that of North American boreal forests like those in Alaska and western Canada.
