The Great Global Warming Swindle: Worst-Case Global Warming Scenarios Not Credible...

Time to turn the page on the Great Global Warming Swindle. It is, and always will be a NWO Global Government scam. Folks need to stop going all-in on fear. Time to move on.


Worst-case global warming scenarios not credible: Study

Earth's surface will almost certainly not warm up four or five degrees Celsius by 2100, according to a study released Wednesday which, if correct, voids worst-case UN climate change predictions.

A revised calculation of how greenhouse gases drive up the planet's temperature reduces the range of possible end-of-century outcomes by more than half, researchers said in the report, published in the journal Nature.

"Our study all but rules out very low and very high climate sensitivities," said lead author Peter Cox, a professor at the University of Exeter.

Cox and colleagues, using a new methodology, have come up with a far narrower range: 2.2 C to 3.4 C, with a best estimate of 2.8 C (5 F).

If accurate, it precludes the most destructive doomsday scenarios...

The climate sensitivity values have been dropping. This new one seems a bit high.

The interesting point of that paper is the narrowing of the range.

Climate science has taken a lot of abuse for not improving on the estimate made in the seventies of 1.5-4.5.

The IPCC did change this range to 2.0-4.5 with a best estimate of 3, back in AR4. In the AR5 they went back to 1.5-4.5 and refused to give a best central estimate.

While I doubt that this paper was conceived solely to reduce the size of the range, and reduce the humiliation of not improving it over the last 40 years with billions spent on climate research, I imagine great pains were taken to reduce the uncertainty.
