This is probably the Nature article they're talking about:
There was once little difference between equatorial and arctic climates.

Thanks for the link. That's a good article and it's easy to understand. I would have expected "Nature" magazine to be more sympathetic to "Earth Tone Al" while he is out pimpin' his disaster "movie." I guess I was wrong. (Again!) I expect Earth Boy to challenge the timing of the release of this article. LOL!
