I think the first comment sums up the tragedy of this situation very clearly:
So privately they said the series had a “dubious relationship to temperature”, but publicly they said it was “well calibrated”? I am just about to the point of never trusting any scientists at all.
The willingness of the climate field to whitewash the fraud and corruption revealed by the first set of climategate emails is now haunting this field badly. Why should anyone believe anything any global warming scientist ever says? It is very clear that too many of them put politics above science in their work.
