Hockey Stick

The individual (or individuals) who, in November 2009, released 1,000 emails to and from IPCC-affiliated climate scientists, igniting the Climategate scandal, struck again earlier this week. The leaker(s) released an additional 5,000 emails involving the same cast of characters, notably Phil Jones of the Climatic Research Unit (CRU) at the University of East Anglia, and Michael Mann, creator of the discredited Hockey Stick reconstruction of Northern Hemisphere temperature history. The blogosphere quickly branded the new trove of emails “Climategate 2.0.”

The timing in each case was not accidental. The Climategate emails made painfully clear that the scientists shaping the huge — and hugely influential — IPCC climate change assessment reports are not impartial experts but agenda-driven activists. Climategate exposed leading U.N.-affiliated scientists as schemers colluding to manipulate public opinion, downplay inconvenient data, bias the peer review process, marginalize skeptical scientists, and flout freedom of information laws. Climategate thus contributed to the failure of the December 2009 Copenhagen climate conference to negotiate a successor treaty to the Kyoto Protocol. Similarly, Climategate 2.0 arrives shortly before the December 2011 climate conference in Durban — although nobody expects the delegates to agree on a post-Kyoto climate treaty anyway.

Excerpts from Climategate 2.0 emails appear to confirm in spades earlier criticisms of the IPCC climate science establishment arising out of Climategate. My colleague, Myron Ebell, enables us to see this at a glance by sorting the excerpts into categories. [click to continue…]
