I wasn’t going to comment, but I think this is interesting irrespective of AGW:
“The CRU e-mails as published on the internet provide prima facie evidence of determined and co-ordinated refusals to comply with honourable scientific traditions … The principle that scientists should be willing to expose their ideas and results to independent testing and replication by others, which requires the open exchange of data, procedures and materials, is vital.”

My thoughts on the substantive issue are fairly reflected in this post.
