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.
