  •  Holy crap. 8 degrees F.?? (5+ / 0-)

    Way beyond all the projections I've seen to date. Is this set to start now, or is it a gradual increase? I'm having a hard time ingesting that graph, but I know it's accurate.

    •  Define gradual. Even if it happens over the next (5+ / 0-)

      500- 1000 years, and 8 degrees F increase is way, way too fast.

    •  Has been projected by 2100 for several years (10+ / 0-)

      It was the worst case scenario in "Climate Change Impacts in the US" that came out 3-4 years ago, and in a Royal Society symposium 2-3 years ago.  This is for 2100.  The climate coninues to warm for centuries from the CO2 already in the atmosphere.  Barring some unforeseen development, humanity is toast.

      We are already seeing the effects, and they will be visible to all but the most hardcore deniers in another 10 years.  We are already probably past a few tipping points (permafrost melting, sea ice melting).  Things become pretty unliveable in some areas by midcentury.  The biggest temp rises in the continental US are predicted to be in the upper plains states.  I'll look for a link.

      The scientific uncertainty doesn't mean that climate change isn't actually happening.

    •  Link to NOAA Draft Report (9+ / 0-)

      Here is a link to NOAA's latest draft report or at least an article about it, with very scary charts.  The projection is for 2100.  What they never saucy is that it then would continue to get hotter if carbon emissions continue at current rates.  Which they will not, because the temperature changes in those charts will cause serious disruption if not economic and social collapse.

      I recently saw An Inconvenient Truth again and was amazed at how much faster the climate is now changing than Al Gore forecast, and he was considered out there when he made the film.

      All the news just gets worse and worse and we do nothing.

    •  2-4C warming was the original 1990 IPCC range (8+ / 0-)

      But we are on the path to 4C.....

      •  at 1.5C the permafrost of Siberia begins (7+ / 0-)

        melting at a rate that will renew the forming of stalagmites and stalactites in the cave systems below it.

        What that will serve as a symbol for will be the vast quantities of CO2 and CH4 being released into the atmosphere above ground. When that happens, the atmosphere will heat rapidly and unpredictably.

        We, those of us alive today, must do something or civilization as we know it will fail and survival of humanity will be at great risk. We are the last generation to have the ability to act. Humanity can never hope to counter inevitable permafrost CO2 contribution, especially while extreme heat conditions are causing societies collapse.
