  •  Going to the IPCC Report linked above (12+ / 0-)
    Paleo sea level records from warm periods during the last 3 million years indicate that global mean sea level exceeded 5 m above present (very high confidence)1 when global temperature was up to 2°C warmer than pre-industrial (medium confidence).
    If global sea levels were 5 m or 15 feet above present at  2°C warmer than pre-industrial what will we see at a present worst case rise of 8.6 °F?

    The conversion between degrees C and F might be taken at 30 °C = 86° F, so that when the temperature is say 95°F it equates to 35 °C.

    By the turn of the century sea level rise might then easily be more than twice the 5 m projected at 2°C and we would see the 5 m rise before 2050.

    The study projects that global surface temperatures are likely to exceed 2.7°F above preindustrial levels by the end of the century and will likely range from 0.54°F to 8.64°F above 1986-2005 levels, depending on greenhouse gas emissions.

    •  For those of you bitching about the cold today (12+ / 0-)

      I think you are gonna miss it when its all gone. That may not be too far in the future. No more sea ice will hit 2 - 6 years from now.

      As the permafrost melts and the methane hydrates begin to enter the earth's atmosphere it may get to where all the oxygen burns off. All the species that replace it are endangered.

      We could have dealt with it, mediated it if we started in time, but we didn't. On the other hand there is still plenty of ocean front property in places like Ellesmere island.

      •  While you're right about the effects of GCC, it (9+ / 0-)

        isn't much comfort when yer bits turn to blue and yer pissin' ice cubes!

        This is a brutally cold winter for many of us, and we are cranky.  It is a first world problem, but we are human, after all.  

        We cannot call ourselves a civilised society if we refuse to protect the weakest among us.

        •  So the other day it got to -45 (9+ / 0-)

          and it was snowing and blowing so there was a little wind chill. It was trap day on Monhegan where I wouldn't have wanted to be out on the water in it, but ashore everything got canceled. We just slept late put another log on the fire, had breakfast and I dressed warm when I went out to shovel and check on the neighbors.

          I really can't think of another winter where there was snow and cold together, maybe one winter when I was in college and was skiing down the banks of the Mississippi river with it -50 and drinking grog but not here in Maine. There are stories of the bay freezing over and being able to walk out to some of the islands, but most years there is just sea smoke.

          Here that's unusual cold, winters are pretty workable, I can remember just shoveling the snow off the roof, passing around some Rhum with an H and going back to shingling, back when people used to still do that with hammers, not wearing gloves so my fingers would begin to toughen up for when it got really cold the rest of the year.

          Here it is a few days later and having positive numbers it feels like indian summer. I find myself getting nostalgic imagining myself trying to tell my grandkids about when there used to be snow in drifts and having them not remember it.
