When the AGW crowd began to demand we all bow down to a so-called scientific "consensus", the religious fervor was revealed. Consensus is not a word that belongs in science..it belongs in politics and religion. Paradoxically, the word skeptic is the core value that drives good science. Denier is an ad hominem attack. You'll notice that religious fervor is exactly what the AGW camp is trying to generate, evidenced by their own pronouncements.
But let's be fair here, and show an example of both sides of a very critical issue, that of Michael Mann's work. Read both sides, and come to your own conclusion.
From Michael Mann's own camp:
RealClimate: Cuccinelli goes fishing again
From the people who claim that Mann's Hockey Stick was basically a "garbage in/hockey stick out" program:
An Open Letter to Dr. Michael Mann | Watts Up With That?
(I admit to being fairly biased towards the findings of McIntyre, btw)
