John Cook, a blogger who runs the site with the ambush title “SkepticalScience” (which unskeptically defends the mainstream position), has tried to revive the put-down and smear strategy against the thousands of scientists who disagree. The new paper confounds climate research with financial forces, is based on the wrong assumptions, uses fallacious reasoning, wasn’t independent, and confuses a consensus of climate scientists for a scientific consensus, not that a consensus proves anything anyway, if it existed.

Given the monopolistic funding of climate science in the last 20 years, the results he finds are entirely predictable.

The twelve clues that good science journalists ought to notice:

1. Thousands of papers support man-made climate change, but not one found the evidence that matters

Cook may have found 3,896 papers endorsing the theory that man-made emissions control the climate, but he cannot name one paper with observations that shows that the assumptions of the IPCC climate models about water vapor and cloud feedbacks are correct. These assumptions produce half to two-thirds of [...]
