We can see what will happen but I’d wager that the IAC will find the IPCC to be almost perfect. What generally seems to happen when institutions investigate them selves. It’s going to be available 8/30/10 at http://reviewipcc.interacademycouncil.net/.
Whitewash or not it should be an interesting read. Note at their website it’s described as “an independent review of the processes and procedures of the Intergovernmental Panel on Climate Change (IPCC).” Funny, like other recent investigations they don’t seem interested in the actual science.
At the below link you can reserve your copy and even submit your comments about it. I wonder if the comments button will disappear shortly after the report comes out?
