On Facebook a question was asked of Willis Eschenbach and an answer given. Willis nails it.
Q. Willis... do you consider yourself a denialist?
A. Mmmm ... an excellent question which likely won't go the way you think.
First, the term "denier" was specifically chosen for its overtones of Holocaust denial. It is used as a pejorative term for anyone who disagrees with any aspect of climate science, usually without any attempt to say what the person is "denying".
The link with Holocaust denial is in what is being denied. The clear implication in both cases that you are DENYING THE TRUTH.
This pre-empts entirely the discussion of what might or might not be true about the climate. It subtly but strongly is saying that THE TRUTH about the climate is already established.
Not only is THE TRUTH established, but the further claim in calling someone a "climate denier" is that YOU know the truth and further that you know that I am "denying" THE TRUTH that is already established.
And the further claim is that THE TRUTH is not just established, but it is as solidly established as the undeniable fact that the Holocaust occurred.
So when you call someone a "climate denier" or a "denialist", you are implicitly asserting that the following are true:
• THE TRUTH about the climate has been established.
• THE TRUTH about the climate is as solid and fact-based as THE TRUTH about the existence of the Holocaust, i.e. 100% true.
• You know THE TRUTH about the climate.
• You know that the person you are calling a "denier" doesn't just disagree about a scientific idea, they deny something that is obviously and demonstrably true.
All of that makes the use of "denier" an underhanded attempt to get people to believe that climate science is settled ... and that is absolutely not THE TRUTH ...
The proper term for folks that disagree with various aspects of the mainstream climate scientists' claims about the climate is "skeptic". They are properly skeptical of the unproven idea that the temperature of the earth is greatly affected by the CO2 going from three-hundredth
It might be true, but it is assuredly unproven.
However, me, I don't consider myself a skeptic. I consider myself a heretic, meaning that I do not agree with the current underlying fundamental assumption of how the climate works.
That underlying assumption is that if you increase the amount of "downwelling" radiation, meaning the sum of solar radiation and thermal radiation from the atmosphere and clouds, the surface temperature has to rise. Not only that, but the rise
Now, intuitively you'd think that would be true, that the more radiation hits some surface the warmer it would get. We're told that it's just "simple physics".
However, the climate is an immensely complex system, with important phenomena on a time scale from nanoseconds to millennia and physical scales from nanometres to planet-wide.
Not only that, but according to the Constructal Law the climate actively responds to the changing conditions.
So as an example of the thermal response to increased radiation of another complex system, consider how much your core body temperature rises when you walk from the shade into the sun. Thermal input has gone up by hundreds of watts per square metre and the core body temperature has ... done nothing ...
So I do NOT believe what almost everyone in the field believes, which is that global temperature is a linear function of the amount of incoming radiation. I say that the climate responds to changing radiation input just as the body responds to changing radiation, by shifting and evolving in such a fashion as to negate the increase in radiation.
The climate is best modeled as a heat engine. Like all heat engines, it has a hot end (the tropics) and a cold end (the poles). Like all heat engines, it turns energy into the mechanical motion. The climate heat engine turns solar energy into the mechanical motion of the various circulations of the atmosphere and the oceans. The frictional resistance to these mechanical motions of ocean and air is equivalent to a brake on a heat engine. And here's the interesting part.
Over the last century, the average temperature of the planet-sized heat engine that we call the "climate" varied by only about one-tenth of one percent ...
So I study not what most all climate scientists study, which is why the global average temperature varies so much.
I study why it varies so little ... which is why I describe myself as a heretic rather than a sceptic.
Good question,
