Carbon Stored in Arctic Soils Higher Than Previously Thought

The study, entitled High stocks of soil organic carbon in the North American Arctic region, analyzes 117 1-meter deep measurements of soil organic carbon in the North American Arctic region and previously published measurements from the same region. The researchers found that soil organic carbon stores are highly dependent on landscape type, and extrapolating from their measurements, the authors estimate that the total organic carbon pool in North American Arctic soils is 60 percent higher than previously estimated.

A recent article Global warming time bomb trapped in Arctic soil: study highlights that these measurements are not included in current climate models and that landscapes in Europe and Russia probably contain a comparable amount of carbon.

The potential release of these greenhouse gases into the atmosphere from the thawing of permafrost is a dangerous feedback loop that we must not let happen.
