  •  one important point about communicating to (7+ / 0-)

    the public - we should always rescale these predictions to Farenheit.  Most Americans have no intuitive feel for the differences in the scales.

    Most Americans will see it as 2 "degrees" or 4 "degrees" without realizing the vast difference between the F and C scales.

    Then the deniers will pick up on this and mislead by talking about "degrees" without any reference to scales.

    •  Yes! I was confused when I first started reading (2+ / 0-)

      about global warming. I went and looked it up and don't remember even now the conversion other than the fact that the science being expressed in C made it seem significantly less than when I converted the numbers into F.

      •  Here you go, C to F Conversion (0+ / 0-)

        C x 9/5 = F (for relative degrees, not for specific temperatures)

        So, 7C Warming = 12.6F
        5C = 9F
        3.5C = 6.3F
        2C = 3.6F

        And these are global averages.  The poles will warm much more than the equator, so bye bye Greenland and (eventually) Antarctica.  As Jim Hansen puts it, we will live in an ice-free world.  That means sea level rise of 280 feet eventually (not this century), but 6 feet this century is likely and 20 feet is not out of the question.

        Remember, the graph above is "no policy", with policy (like the upcoming COP15 conference to replace the Kyoto Protocol, things won't be nearly as bad (though they will still be quite bad!).

      •  OK, I've added Fahrenheit to the post (0+ / 0-)
    •  Thats the problem (0+ / 0-)

      scientists are acting like scientists. They use the scale that actually makes sense, not the one that is better for informing the public. Of course, it shouldn't be the job of scientists to inform the public, that is what the media is for(... you can stop giggling now).
