Did you hear about Climategate? This is a must read. Apparently some hackers broke into a database at one of the huge climate change research organizations in the UK (one of four who supplied the data for the UN IPCC report, btw) and found a lot of damning emails which slam skeptics, including having journals not publish their research, as well as suggestions for suppressing data that is unfavorable to the cause. This type of stuff isn't really surprising to me though.
