The science is NOT settled

The headline "It's worse than they thought: Warming is slower than predicted" (by Christopher Monckton) was enough to perk my curiosity.
Great headline, good story, though admittedly awash with technical details that make it hard to follow. Still I waded through to the end. In case you don't have the patience a potted summary goes like this; -

• In a recent paper "Emission budgets and pathways consistent with limiting warming to 1.5 °C", climatologists Millar et al. have reported that global warming is not as rapid as their models have been predicting

• Monckton uses the figures in that paper together with IPCC models to demonstrate that the models are not only slightly out, but way out.  For example he cites that the measured global warming since 1850 is ~ 1 C(degree) whereas models predict this to be 2.75 C
• The current rate of warming is ~ 0.45C per century and with predicted increases in CO2 over the period , with some assumptions that you will have to read through yourself, the 1.5C target increase in global temperature by 2100 may be achieved without any mitigation efforts.

 It all leads to a rather stunning conclusion;-

"Though the Millar paper serves to conceal the true extent of the official exaggerations on which demands for “climate action” have been unwisely based, it is at another level an early crack in the dam that indicates that the entire edifice of nonsense is about to fail. Have courage! The truth that global warming will be small, harmless and net-beneficial will soon prevail over the screeching extremists. The Millar paper is not the beginning of the end, but it is at least the end of the beginning."

Well we will see. But one thing is sure, "the science is NOT settled"!
