global warming 

Many thanks for your message.  Unfortunately I saw it too late, but actually the quote (as properly quoted, not as originally misquoted) is quite informative, and this is what I've picked up on.  You'll see my edit to the article, and my followup comment on talk.  I'll leave others to do with it as they see best.  Feel free to change anything I wrote that doesn't fit in well with the article.
