lol, its hilarious that someone is using a paper from a member of the british gentry on this of all forums!
have a look at the background of lord monckton (basically a corporate lackey) and decide for yourself if its worth believing he has anything to add to the climate change debate.
hell, he argued that "there is only one way to stop AIDS. That is to screen the entire population regularly and to quarantine all carriers of the disease for life" back in the late '80's.
As for his article....
here is a critique of everything in it:
www.altenergyaction.org/Monckton.html

also from wikipaedia:
"Gavin Schmidt (a doctorate level climatologist)has criticised Monckton's analysis of climate sensitivity as "sleight-of-hand to fool the unwary".[10] Dr. Stephan Harrison criticises Moncktons' articles as "full of errors, misuse of data and cherry-picked examples".[11] The British writer and environmentalist George Monbiot has criticized Monckton's arguments as "cherry-picking, downright misrepresentation and pseudo-scientific gibberish."

here also is a reasonable challenge to Monckton's paper:
