Monckton on blackbody radiation

I wrote to Christopher Monckton a while back to ask him about a post Blackbody – the key error in climate science, and bless his soul, he whipped off a letter with his detailed answer and wrote it all back to me, saying that other people were asking him about that too. It’s a shame to keep it hidden and high time I brought it out. Usually this topic generates quite a discussion. Though, warning (!) it contains equations, and primarily discusses the physics of blackbody radiation from Earth. It is essentially a debate about the core physics among a few skeptics. The most curious thing being that this time — this blog is on the mainstream end of opinions. (Yes, I think there is a greenhouse effect as I explained here and here).

Huffman asserts there is no measureable greenhouse effect on Venus and Earth and that the temperatures of both planets is determined by their distance to the sun. (Michael Hammer responded to that with an explanation of why we know There is a Greenhouse Effect on Venus). My unsophisticated thought was that if distance explained it all, then ergo, albedo would have no effect at all [...]
