The CRU Hack: One year later

I woke up on Tuesday, 17 Nov 2009 completely unaware of what was about to unfold. I tried to log in to RealClimate, but for some reason my login did not work. Neither did the admin login. I logged in to the back-end via ssh, only to be inexplicably logged out again. I did it again. No dice. I then called the hosting company and told them to take us offline until I could see what was going on. When I did get control back from the hacker (and hacker it was), there was a large uploaded file on our server, and a draft post ready to go announcing the theft of the CRU emails. And so it began.

From that Friday, and for about 3 weeks afterward, we were drafted into the biggest context-setting exercise we’d ever been involved in. What was the story with Soon and Baliunas? What is the difference between tree ring density and tree ring width? What papers were being discussed in email X? What was Trenberth talking about? Or Wigley? Or Briffa or Jones? Who were any of this people anyway? The very specificity of the emails meant that it was hard for the broader scientific community to add informed comment, and so the burden on the people directly involved was high.

The posts we put up initially are still valid today – and the 1000’s of comment stand as testimony to the contemporary fervour of the conversation:

• The CRU Hack
• The CRU Hack: Context
• Where’s the Data?
• The CRU Hack: More Context

I think we did pretty well considering – no other site, nor set of scientists (not even at UEA) provided so much of the background to counter the inevitable misinterpretations that starting immediately spreading. While some commentators were predicting resignations, retractions and criminal charges, we noted that there had not been any scientific misconduct, and predicted that this is what the inquiries would find and that the science would not be affected. (Note, the most thorough inquiry, and one that will have to withstand judicial review, is the one by EPA which, strangely enough, has barely been discussed in the blogosphere). …
