For major surgery, it is often best to get a second opinion, and to look at the record of the proposed scientists. They then put up a graph of the accuracy of the IPCC predictions for temperature rise, which I thought worth repeating.
Global Temp, Actual .v. Projected
IPCC projections for temperature rise, against reality. (WSJ)
The response begins thus:
We agree with Mr. Trenberth et al. that expertise is important in medical care, as it is in any matter of importance to humans or our environment . . . . . . . . . . In this respect, an important gauge of scientific expertise is the ability to make successful predictions. When predictions fail, we say the theory is “falsified” and we should look for the reasons for the failure.
