There’s troubles with commenting at the NYT so I will re-post some of my notes to Revkin’s “Does an Old Climate Critique Still Hold up?” here:
(a) Given all the discussion taking place now, and the glaring mistakes obvious to all, it is apparent that nobody has ever read the IPCC report at a meaningful level of detail. A professional editor and a pre-established maximum number of pages should be there for AR5.
(b) I am not sure how to reconcile Dr Hegerl’s statement “We felt Andrew Lacis’ comment reflected that he couldn’t clearly see where statements came from, which is why we strengthened the pointers from the technical sections to the executive summary” with the note to Dr Lacis’ expert comment “Rejected“. Usually, rejected comments are not acted upon.
(c) I’d suggest people drop the “Greenhouse effect is simple 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)
(d) Call me old-fashioned, but I find “post-normal science” a misnomer (almost, a case of reification). “Post-normal science” is not “science” and should be defined with a more appropriate moniker.
