Hide the Decline- 13 years of Climategate

Poneke has written a blog post on the Climate Gate e-mails.

Having now read all the Climategate emails, I can conclusively say they demonstrate a level of scientific chicanery of the most appalling kind that deserves the widest possible public exposure.

The emails reveal that the entire global warming debate and the IPCC process is controlled by a small cabal of climate specialists in England and North America. This cabal, who call themselves “the Team,” bully and smear any critics. They control the “peer review” process for research in the field and use their power to prevent contrary research being published.

The Team’s members are the heart of the IPCC process, many of them the lead authors of its reports.

and later:

Mann’s final comment above about “the late 20th century decline” is the genesis of the now-infamous “hide the decline” email that is the most quoted of the Climategate treasure trove, almost always out of context. The context is being given here.

Mann went on to say the problem remained that Briffa’s proxy data differed sharply in the late 20th century from his and Jones’s. He continued: This is the problem we all picked up on (everyone in the room at IPCC was in agreement that this was a problem and a potential distraction/detraction from the reasonably concensus viewpoint we’d like to show w/ the Jones et al and Mann et al series. So, if we show Keith’s series in this plot, we have to comment that “something else” is responsible for the discrepancies in this case…. Otherwise, the skeptics have an field day casting doubt on our ability to understand the factors that influence these estimates and, thus, can undermine faith in the paleoestimates. I don’t think that doubt is scientifically justified, and I’d hate to be the one to have to give it fodder!

The problem Mann saw was soon solved, as shown by that infamous email dated November 16 1999, from Phil Jones to Mann, Briffa and others:

I’ve just completed Mike’s Nature trick of adding in the real temps to each series for the last 20 years (ie from 1981 onwards) amd from 1961 for Keith’s to hide the decline.
