Regular readers will recall a recent post pointing to Dr Roy Spencer being
cannabalized cannibalized over his stubborn insistence that the Greenhouse Effect does not violate the laws of thermodynamics.
Well, he seems to be a glutton for punishment as he is taking another crack at it.
This time, I am only pointing it out because he has taken a high tech experimental approach to observe the actual atmospheric back radiation and an interesting post results (hi tech compared to his last hotplate device!).
I just skimmed the comments, like last time, and while the die-hards are still hard to make die, this time there is a little bit more utility in the discussion.
He also shot down another denialist talking point in the coments:
The lack of a hotspot has nothing to do with the existence (or non-existence) of the greenhouse effect. It has to do with how we expect warming to occur as a function of height, especially in the tropics (average lapse rates are different in different parts of the world). If real, the lack of a hotspot says there is something wrong in the climate models, which I agree with.
