  •  Excellent post Fish. Whenever I see exponential (9+ / 0-)

    growth I was trained to search for "positive" feedback loops.  I guess in this case we already have enough candidates with population growth and per capita fossil fuel use.

    But, I've heard occasional worrisome reports, perhaps even from you about two potentially catastrophic feedback loops that if sufficiently stimulated could become beyond our capacity control, possible being extinction level events.  

    1) vast deposits of methane frozen in and under the Siberian tundra, and beneath the oceans under one of the poles, which is apparently already boiling off, and 2) the capacity of the oceans to absorb CO2 being inversely proportional to temperature.

    What do professional climate scientist think of these scenario?  Are they plausible enough we should be concerned, or is this a distraction for the already serious threat of combustion of fossil fuels that we can eventually get control of once we take it seriously enough at a global level?
