== Temperature notation == 

 I mentioned this in a text note, but thought it could use a little more discussion.  The article uses multiple temperature abbreviations, for example, "This raises the temperature of the lower atmosphere beneath the cirrus clouds by an average of ." 

 In giving temperatures, the "R" abbreviation can mean the Rankine scale or the Réaumur scale.  While they're both (little-used) temperature scales, they are distinctly different measures.  I found myself scratching my head before I figured out just what was meant; I even thought it might be vandalism and looked around for the edit in which it (the vandalism) was committed.  I would suggest some less-ambiguous abbreviation for Rankine (which I eventually figured out was what was meant), such as the "Ra" mentioned in Wikipedia.
