    "We expected that because of the long-term warming, we would have lost carbon stored in the soil to the atmosphere," said Schimel......
    What they initially found was typical of Arctic warming: low-lying, shallow-rooted vegetation giving way to taller plants with deeper roots; greater wood shrub dominance; and increased thaw depth. What they weren't expecting was that two decades of slow and steady warming had not changed the amounts of carbon in the soil, despite changes in vegetation and even the soil food web.
    The answer to that mystery, according to Sistla, might be found in the finer workings of the ecosystem: Increased plant growth appears to have facilitated stabilizing feedbacks to soil carbon loss. Their research is published in the recent edition of the journal Nature.

    •  Thank you. I've been thinking of the release of (5+ / 0-)

      carbon and methane from Arctic soils as a bomb about to go off.  That it might be less catastrophic than feared is really, really good news.
