The good news is that climate science in his view is not at all impeached by the release of the CRU emails.
The scientific consensus regarding human-caused climate change is based on decades of work by thousands of scientists around the world.The bad news is that some of his colleagues exhibited "poor judgment":
I cannot condone some things that colleagues of mine wrote or requested in the e-mails recently stolen from a climate research unit at a British university. . . Some statements in the stolen e-mails reflect poor judgment -- for example, a colleague referring to deleting e-mails that might be subject to a Freedom of Information Act request -- but there is no evidence that this happened.I doubt that Professor Mann will be getting many cheery Christmas cards from his CRU-email colleagues.
