This is article from The Globe and Mail has a good summary of my thoughts on the subject. This is what I have been a "denier" of, if anything - advocacy in the name of science. Science is not about concensus, nor is it agenda-driven. Furthermore, models are just that - models. Policy is a wholly other thing.
None of this is to say that global warming isn't real, or that human activity doesn't play a role, or that the IPCC is entirely wrong, or that measures to curb greenhouse-gas emissions aren't valid. But the strategy pursued by activists (including scientists who have crossed the line into advocacy) has turned out to be fatally flawed.
By exaggerating the certainties, papering over the gaps, demonizing the skeptics and peddling tales of imminent catastrophe, they've discredited the entire climate-change movement. The political damage will be severe. As Mr. Mead succinctly puts it: “Skeptics up, Obama down, cap-and-trade dead.”
These thoughts are echoed in this HA post, as well:The IPCC doesn’t do science. They do advocacy, mainly for the idea of international control of energy and manufacturing, with a healthy dose of redistribution of wealth. These revelations should put an end to any reliance on IPCC work for American policy, and the UN should be pressured to fire everyone involved in this sham, starting with railroad engineer Rajendra Pachauri.
