The release of hacked e-mails between climatologists has raised some serious questions about how the powers that be in that discipline have approached the debate about climate change. See http://www.nytimes.com/2009/12/01/science/01tier.html?_r=1&scp=1&sq=climate%20change%20e-mail&st=cse
Having spent over 10 years interacting with members of the archaeological community over cultural property issues, I personally feel strong parallels exist between how leaders in both groups have approached the issues. In my opinion, archaeologists need to become far more cognizant of the "peril of trying to spin science" and, with it, supporting the suppression of information adverse to a preconceived position. Climatologists certainly have had to confront these issues because of this scandal-- even if at least some of their number appear to be more interested in tracking down the hackers than in reconsidering their methods.
