The IPCC is the world's most prominent source of alarmist predictions and claims about man-made global warming.
If the IPCC's reports were flawed, as a many global warming "skeptics" have long claimed,
then the scientific footing of the man-made global warming movement --
the environmental movement's "mother of all environmental scares" -- is
IAC reported that IPCC lead authors fail to give "due consideration ...
to properly documented alternative views" (p. 20), fail to "provide
detailed written responses to the most significant review issues
identified by the Review Editors" (p. 21), and are not "consider[ing]
review comments carefully and document[ing] their responses" (p. 22).
In plain English: the IPCC reports are not peer-reviewed.
