"As our March 2020 video on the Climate Sensitivity Question explains, a key issue in climate science is how much warming can be expected from doubling the amount of CO2 in the air"

John Robson of Climate Discussion Nexus takes us once more around the scientific mulberry bush that poses as "settled science".

The extent to which CO2 affects "global warming" would seem to be a critical issue, yet after decades of controversy and innumerable papers scientific and unscientific, the illustrious IPCC still appears unable to get its analysis straight.

"if ECS is down around 2 degrees C the whole basis for imposing costly climate policy falls apart. And apparently it does"

But wait, 

"There's more ... "

Still, if the science is settled, what does it matter?

And if it isn't settled after all these years, then will it ever be?
