A Timely Post on Hansen’s Paper

Apparently while I was posting about Hansen, our friends at C3 were doing the same, although they were more focused on the lack of accuracy I referenced.  In this case, two pictures are worth a 1000 words.  I’m lifting them because they’re graphically better than what I can produce.  Because I’m swiping them, please click on the link to  C3 Headlines which I’m posting.

I would call your attention to the first graphic.  When blown up, you can see the conditions of the various scenarios. 

The scenario which is nearest to the actual temps is scenario C.  From Hansen’s text, scenario C is described as this……

Obviously, towards our emissions, we didn’t get anywhere close to scenario C, as can be seen in the second graph.  Scenario A assumed continued exponential trace gas growth.

    I think someone could make a very strong argument that all the forcing is below 350ppm, and that’s the saturation point….

    I have internet for a min………

    • suyts says:

      Yeh, the problem is some of the alarmists consider 280ppm as the baseline, but it isn’t. Oddly, when considering doubling of CO2, the we’ve done it about 8.5 times or 2&#8328.5;

      • suyts says:

        lol, well that didn’t work….. 2^8 and then 1/2 of the next doubling.

      • Latitude says:

        I would say that 280 slows plant growth to the point that CO2 is limiting…

        It’s amazing to me that they know trees and grasses take up large amounts of CO2…
        Plant a tree, and people were getting credits for letting their pastures grow…etc

        But not acknowledge that when conifers and tree ferns evolved, CO2 levels crashed…
        …..extinction event
        then grasses evolved and CO2 levels crashed again

        We wouldn’t even have C4’s if CO2 levels hadn’t become limiting to the C3’s in the first place……

        They say math is hard………chemistry is easy, nice neat little formulas that explain everything
        Only it doesn’t, you can only explain it with biology…and biology is hard

        • suyts says:

          lol, yeh, the idea that CO2 is something to be concerned with fails to acknowledge past scientific contributions. But, to me, its all hard.

        • Latitude says:

          Here’s all you need to know…..

          C4’s evolved when CO2 levels were in the high 200’s…..

          ..there’s a reason

          C3’s were having a hard time coping with low CO2 levels, C4’s evolved to out compete them……..the combination of C3’s, which take up a lot of CO2, and C4’s, which evolved to live with lower CO2 levels, has kept CO2 levels limiting to plants

          Think of it as a plant in a pot…
          …if you don’t add fertilizer every now and then, it will stop growing

        • suyts says:

          Life finds a way.

        • Latitude says:

          Exactly….
          They say it’s happening too fast….faster then it’s ever happened….blah blah
          Then what happened to the dinosaurs……

    The linear growth of trace gasses exceeded scenario A and the temperatures fell below those for scenario C.
    Works for me! they can defend Hansen’s work all they want to. It saves me from having to make them look like fools.

    Nice post suyts! I’m swiping this as well and putting into my ever enlarging Hansen file. 🙂

    • suyts says:

      Feel free to swipe as much as you feel needed! And thanks! C3’s graphs are really nice looking. I’m just not that much into coloring to be able to produce those appealing graphics.
