The last line of defense regarding the AGW mantra for any advocate of human induced climate alarmism is always the 2007 IPCC report. Not only is it consistently cited as the definitive perspective on climate, it is robustly defended as being the consensus of over 2,500 scientists and the best of science because it is peer-reviewed. Inferred in that defense is that the IPCC is to be trusted as the authority because it is so unlike all those pesky blogs that have ripped holes in the IPCC science, the consensus and the combination of inaccuracies, mistakes and ideological contrivance that is the IPCC report.
Unfortunately for AGW advocates the credibility of the IPCC process and its report suffered in the wake of Climategate, Himalyagate, Amazongate and the rest, the collapse at Copenhagen and the general ignoring of Cancun. Despite this, many have persisted with the peer-reviewed, best science narrative as their rationale for retaining both their belief in AGW and their assertion that the IPCC should be trusted.
Over at her blog, Donna Laframboise has slowly but methodically been scrutinizing the both IPCC and its report, first ripping apart its claims of wide consensus and participation, and now, its claims to peer-review gold standard excellence. Seems fully 30% of the citations contained within the 2007 IPCC report do not originate from peer-reviewed sources.
So, to re-cap. Not only do we know that the IPCC process contrived to exclude data and papers that contradicted its dogma, we now have evidence that 30% of those sources that were used were non peer-reviewed.
Trust: not so much.
Authoritative: hardly.
Driven by ideology: definitely.
We only get answers to the questions we ask. The IPCC was never mandated to ask the right questions. Still isn't.
