Professor Johnson is pointing to the heart of the matter here, that this 'settled science' doesn't just suffer from modeling difficulties but is inherently incoherent, a fatal flaw which most physicists have so far failed to notice. AS.
Several Eminent Physicists are Skeptical to AGW
Freeman Dyson: The real world is muddy and messy and full of things that we do not yet understand. It is much easier for a scientist to sit in an air-conditioned building and run computer models, than to put on winter clothes and measure what is really happening outside in the swamps and the clouds. That is why the climate model experts end up believing their own models.
Robert Laughlin: The geologic record suggests that climate ought not to concern us too much when we’re gazing into the energy future, not because it’s unimportant, but because it’s beyond our power to control.
Edward Teller: Society's emissions of carbon dioxide may or may not turn out to have something significant to do with global warming--the jury is still out.
Frederick Seitz: Research data on climate change do not show that human use of hydrocarbons is harmful. To the contrary, there is good evidence that increased atmospheric carbon dioxide is environmentally helpful.
Robert Jastrow: The scientific facts indicate that all the temperature changes observed in the last 100 years were largely natural changes and were not caused by carbon dioxide produced in human activities.
William Nirenberg: The available data on climate change, however, do not support these predictions, nor do they support the idea that human activity has caused, or will cause, a dangerous increase in global temperatures. ...These facts indicate that theoretical estimates of the greenhouse problem have greatly exaggerated its seriousness.

We see that the main skeptical argument used by these eminent physicists is that climate modeling is complex and that observations do not match very well with observations. Fair enough.
But the eminent physicists do not criticize the very physics basis of climate alarmism
: the greenhouse effect supposedly resulting from atmospheric backradiation. The mantra that says that doubled CO2 will cause a global warming of 1.2 C, by basic physics which cannot be questioned by anybody eminent or not.
Does it mean that the eminent physicists possess a basic physical theory supporting the mantra of the greenhouse effect and backradiation? No, it does not seem to be the case. It seems that this theory is hanging freely in the air, because upon scrutiny it evaporates into the atmosphere. Maybe it is now time for eminent physicists to make this clear to the World and its people and leaders?
