"Convinced" is a little strong. I think it is an interesting idea and it seems plausible to me. But I know f-all about it really so I can't say whether it is true or not and since I don't have a burning reason to accept or reject it, I'll just keep an open mind when something else comes along. You on the other hand with your unbreakable faith in it not being climate-change related will doubtless grab at anything that tries to refute it.

I for one feel we have flogged this poor horse to death...
