As usual Dr Judith Curry puts the hype into perspective...
"The group that I like is really the NOAA group in Boulder, who looks at the historical record and tries to see is there anything unusual.
Looking back a hundred years, is this exceptional in any way? If it is not particularly exceptional, given the record we have for the last hundred years, then it’s hard to argue that climate changed. Occasionally we do get genuinely record-breaking events. Then we need to trace back to what was the atmospheric dynamics, and whatever that contributed to that event and you need to tease it out. It needs a lot of detective work.
There is this new movement to use climate models with natural variability, and then human-caused global warming, but these same climate models they’re using can’t resolve these extreme events. They can’t produce hurricanes, they don’t have the right event-weather distribution to provide heatwaves. It is just Voodoo statistics that they’re playing with these models — which do not have the capability to predict these extreme events in the current climate or an unperturbed climate anyways. I’m not very impressed with the model-based attribution arguments. Carefully-constructed diagnostic analysis and comparisons with historical events — to me those are of much more value."
Dr Curry operates a hurricane and weather forecasting business now after being the director of a major college science program and she hits the nail right on the head. NATURAL VARIATION...
