“100% certainty is almost always an indication of a cult rather than any sort of actual truth”

Jay Currie looks at the reaction to a Bret Stephens climate article in the New York Times:

On the science side the greatest threats were the inadequacy of the climate models and the advent of the “hiatus”. The models entirely failed to project any circumstances in which temperature ceased to rise when CO2 continued to rise. However the hiatus created exactly that set of conditions for what is now looking like twenty years. (Right this instant, last year’s El Nino, broke the hiatus. However, rapidly cooling post El Nino temperatures look set to bring the hiatus back into play in the next six months to a year.)

The economic side is even worse. It turns out that renewable energy – windmills and solar – costs a fortune and is profoundly unreliable. Governments which went all in for renewables (see Ontario) found their energy prices hockey sticking and the popularity plummeting without, as it turns out, making even a slight impression on the rise of CO2 concentrations.

The economics of climate change and its “mitigation” are a shambles. And it is beginning to dawn on assorted politicians that they might have been railroaded with science which was not quite ready for prime time.

Which makes it all the more imperative for the Nuccitelli and DeSmog blogs of this world to redouble their attacks on even mildly sceptical positions. Had the alarmists been less certain their edifice could have easily withstood a recalibration of the science and a recalculation of the cost/benefits. But they weren’t. They went all in for a position which claimed to know for certain that CO2 was driving world temperature and that there was no other possible cause for an increase or decrease in that temperature.

The problem with that position is that it was premature and very brittle. As lower sensitivity estimates emerge, as other, non-CO2 driven, temperature controls are discovered, consensus climate science becomes more and more embattled. What had looked like a monopoly on political discourse and media comment begins to fray. The advent of Trump and a merry band of climate change skeptics in the regulatory agencies and in Congress, has pretty much killed any forward motion for the climate alarmists in the US. And the US is where this battle will be won or lost. However, the sheer cost of so called “carbon reduction” schemes in the UK, Germany and the rest of Europe has been staggering and has shown next to no actual benefit so scepticism is rising there too. China has both embarked on an embrace of climate change abatement and the construction of dozens of coal fired electrical generation plants every year.
