I have not had the beer so I can't vouch for his report but I trust what he says. If I am not mistaken skunked beer is produced by uv rays getting to the beer not by temp.
Yes, you are correct regarding the UV rays. It is I who was mistaken, I shouldn't have used the term "skunked." http://www.sciencedaily.com/releases...1018071707.htm
I think "stale" is more accurate. Higher storage temperatures, especially temperatures approaching 90*F and above, undoubtedly speed the aging process. This can quickly result in stale beer. A quick google should yield the answer.
