Global warming time bomb trapped in Arctic soil: study

Previous estimates of the Arctic carbon pool relied heavily on a relative handful of measurements conducted outside of the Arctic, and only to a depth of 40 centimetres (15.5 inches).

The study, published in the British journal Nature Geoscience, found that the stock of organic carbon "is considerably higher than previously thought" -- 60 percent more than the previously estimated.

This is roughly equivalent of one sixth of the entire carbon content in the atmosphere.

And that is just for North America.
