Pat Michaels explains the real meaning of the Climategate emails in the Wall Street Journal here. The emails not only discredit some leading climate scientists, they discredit the scientific journals that those scientists bullied into rejecting articles that questioned the climate change ideology. 

A sample:

Mr. Mann called upon his colleagues to try and put Climate Research
out of business. “Perhaps we should encourage our colleagues in the
climate research community to no longer submit to, or cite papers in,
this journal,” he wrote in one of the emails. “We would also need to
consider what we tell or request of our more reasonable colleagues who
currently sit on the editorial board.”

After Messrs. Jones and Mann threatened a boycott of publications
and reviews, half the editorial board of Climate Research resigned.
People who didn’t toe Messrs. Wigley, Mann and Jones’s line began to
experience increasing difficulty in publishing their results.

This happened to me and to the University of Alabama’s Roy Spencer,
who also hypothesized that global warming is likely to be modest.
Others surely stopped trying, tiring of summary rejections of good work
by editors scared of the mob. Sallie Baliunas, for example, has
disappeared from the scientific scene.
