Vast Amount of Arctic Carbon Could Be Released
(LiveScience.com)
|
LiveScience.com - As global warming thaws the frozen soils of the Arctic, more stored-up carbon could potentially be released into the atmosphere than previously thought, a new study suggests.
Much of the frigid Arctic's soil is permafrost, or permanently frozen ground.
Seasonal freeze-thaw cycles can mix up the soil layers, a process called cryoturbation, forcing organic (carbon-based) material into the subsurface layers and storing it in the permafrost.
With Arctic temperatures projected to rise up to 10. ...
