A very thought provoking article, bagitha - thank's for posting it. I've just read it and came away with a very simplistic conclusion that Climatology could be seen to be a new religion. Proof, or otherwise, can be manipulated to suit the masses, depending upon the financial and political needs of any particular time, by those who bang the drum the hardest. I rather fear that I am still gambling with snake-oil salesmen, if and when I chose to pin my ribbon to any one particular view/ cause.
At least by suggesting a criteria (the a,b,c, etc.) the professor is attempting to aid clarity and to promote lateral thinking around this whole issue. The cynic in me says he may yet be another drum banger, albeit it a plausible one.

..... and there I was thinking I didn't have a mathematical brain in the slightest! So it's nice to have a bit of hope......
