Celebrated Physicist Calls IPCC Summary “Deeply Unscientific” Reply

Former CERN official says 65 prominent IPCC authors have abandoned “scientific rigour.”

Pierre Dariulatte CERNHere’s a direct quote from Darriulat’s submission:

The way the SPM deals with uncertainties (e.g. claiming something is 95% certain) is shocking and deeply unscientific. For a scientist, this simple fact is sufficient to throw discredit on the whole summary. The SPM gives the wrong idea that one can quantify precisely our confidence in the [climate] model predictions, which is far from being the case. [bold added]

Darriulat says “the main point to appreciate” is that, because the Summary was written for policymakers rather than for other scientists, it “can not be a scientific document.” His next remarks deserve to be displayed on every billboard in Times Square:

When writing the SPM, the authors are facing a dilemma: either they speak as scientists and…recognize that there are too many unknowns to make reliable predictions…or they try to convey what they “consensually” thinkat the price of giving up scientific rigour. They deliberately chose the latter…they have distorted the scientific message into an alarmist message… [bold added; click here for the full, unedited version]  *** continue
