  •  Perhaps the most relevant question. (5+ / 0-)

    Or for that matter, what hasn't been discovered yet.

    Ancient carbon trapped in Arctic permafrost is extremely sensitive to sunlight and, if exposed to the surface when long-frozen soils melt and collapse, can release climate-warming carbon dioxide gas into the atmosphere much faster than previously thought.

    •  Interesting that methane isn't mentioned in that (1+ / 0-)

      quote.  It's a much larger climate bomb waiting inside the permafrost, from all I've read. Maybe I'm missing something.

      •  Carbon dioxide has a far longer atmospheric life (3+ / 0-)

        That specific article pointed to the revelation that the permafrost holds a catastrophic amount of carbon dioxide, in addition to the methane.

        Tremendous stores of organic carbon have been frozen in Arctic permafrost soils for thousands of years. If thawed and released as carbon dioxide gas, this vast carbon repository has the potential to double the amount of the heat-trapping greenhouse gas in the atmosphere on a timescale similar to humanity's inputs of carbon dioxide due to the burning of fossil fuels.
