Raypierre Still Doesn't Get It
The guys at RealClimate have absolutely zero debating skills. That much has been known for a long time and has just been confirmed once again with a relatively weak blog containing incredible statements such as
Do the above issues suggest “politicized science”, deliberate deceptions or a tendency towards alarmism on the part of IPCC? We do not think there is any factual basis for such allegations
(stand-up comedy shouldn’t be far)
(yes, that blog is weak because it pivots on a mere handful of arguments, all of them at risk of being shown fallacious. The first one that goes, will carry the rest of the blog down with itself)
Those minimalistic skills are now spreading elsewhere, with the most simplistic of logical reasoning apparently beyond the grasp of “raypierre”, aka Raymond T Pierrehumbert. Next to Andy Revkin’s “Does an Old Climate Critique Still Hold up?” I had originally posted the following comment of Feb 10, 9:09EST (also available in my “Lacis, The IPCC, Simple Physics And Post-normal “Science”“)

[…] (c) I’d suggest people drop the “Greenhouse effect is simply physics” argument. Simple physics shows that warm air moves upwards, and a room’s floor is generally colder than its ceiling. However, mountaintops are generally colder than sea-level locations. Why? Because the free atmosphere is a complex system where you can’t just apply simple physics (for a different example: think of anti-oxydants’ wonders in Petri dishes and the failure to translate that into effective anti-aging treatments in the real world) […]
I do think that the Petri dish analogy made my point extremely clear. Alas, not to all…

No, Maurizio, we should not drop the argument that “the Greenhouse Effect” is simply physics. It IS simply physics. What needs to happen instead is that you and people like you either (a) take the time to learn a little physics yourself, or (b) lacking time, at least defer to people who do know the physics. “a” is by far the preferable option.
For example, mountaintops are colder than the lower altitudes because of the simple physical principle that gases cool when they expand rapidly enough. Convection moves the air upwards fast enough that the air cools. This kind of thermodynamics is taught in most good high school physics classes, and its atmospheric relevance has been understood since shortly after Horace de Saussure’s landmark studies of mountain meteorology in the early 1800’s.
The fact that your comment was recommended by 6 readers so far speaks volumes about the scientific ignorance of many of the readers who support your position.
Why oh why would the Louis Block Professor in Geophysical Sciences at the University of Chicago feel it necessary to demean himself with the last paragraph above, totally undeserving any reply, I will never understand. Obviously though, a career in Geophysical and Atmospheric Sciences may prevent people like raypierre from taking the time to learn a little cellular physiology.
Somebody did try to re-iterate my point:

raypierre, a big time, scientifically qualified alarmist, sez: ‘For example, mountaintops are colder than the lower altitudes because of the simple physical principle that gases cool when they expand rapidly enough.’
I live on a mountain, 10,000 feet high. I’m at 1,500 feet. True, it’s colder at the top, but it’s warmer at 7,000 than at 1,500 feet (most of the time).
Climate and weather are possibly more complex that people like Raypierre would like hoi polloi to know.
No way…help for Prof Pierrehumbert was at hand next day:

[responding to Harry Eagar] Raypierre says that mountaintops are cooler than at the bottom based upon known (and incontrovertible) principle of physics, and this commenter calls him out because ‘mountaintops are colder than the bottom’ because sometimes in between (thru short term warmth rising, I think, some of the time), the air is warmer than at the bottom.
Pierre didn’t give a full analysis of mountain climate, nor was doing so relevant. He simply gave an example of one specific point, correctly stated and which the commenter himself backed up, that was then manipulated into yet another irrelevant but apparently appealing attack upon RayPierre and scientists!
It is what is done on here, often more subtly, however, over and over and over again […]
By the way, Ivan: to state the truism that climate and weather are more complex than the individual effects at play, does not mean “to attack the scientists” any more than to point to the Ediacaran fossils didn’t mean “to attack the scientists”…just those scientists that prevented our understanding of Precambrian fauna for 80 years…
And now for my latest reply. I have no hope raypierre, Ivan Carter or anybody thinking they’re characters in a Fort Apache remake will understand any of it. You see, even if they have lacked the time so far, surely they have never even thought of deferring to anybody that knows anything about movies, or Precambrian fauna…

raypierre (86) and Ivan Carter (109): my original point was that you cannot simply take one effect observed in the lab (for example, the greenhouse effect) and state that it will work as-is in the real world. In the real world, other effects will “sum up” to it, and the end result will be whatever it will be.
The existence of a GH effect is the _starting_ point in the investigation of what happens to climate due to GHG emissions, so it _cannot_ be used to _terminate_ discussions about global warming.
Hence my request to drop it as an argument, just like the existence of gravity doesn’t mean that flying is impossible.
