The report was formally reviewed by an independent panel set up in compliance with the Federal Advisory Committee Act. This FACA panel's report gave a generally favorable review while providing many specific areas where improvements were needed. The advisory committee's greatest concern was that the report tried so hard to be evenhanded and not overstate what we know, that it came close to leaving the impression that we know little in cases where a lot is known. EPA revised the report to satisfy those concerns and published a response to each of the comments. While not taking issue with the report's findings, the Government Accountability Project complained that EPA delayed releasing the report three months so that its results could be excluded from a regulatory finding about whether greenhouse gases threaten public health.
