Since many advocates of anthropomorphic global warming theory have declared the twenty-year-old science to be "settled," then there must not be very much controversy or disagreement in the peer review reader comments to the UN's Fourth IPCC report. Except, no one seems willing to publicize these comments. Even US government organizations paid for by taxpayers. Steve McIntyre is again having to resort to filing FOIA's to get the details of climate research.
Update: It appears that Congress is taking a similar approach to climate research when it comes to openness about earmarks.
