I didn't read anything about prison, either, except for a reference in the headline but I doubt that's a direct quote. I wouldn't know. Other than that, the quote "on trial for high crimes against humanity" is perhaps the one that is most likely to be associated with jail. I wouldn't know that, either. Chance is, of course, that you're reading a different article than I am.

I'm not really a fan of any of the antropogenic global warming models myself but most of all I'm not a fan of the hypes surrounding the whole thing ('hypes' in plural because they exist as an alarmist hype and an alarmist of the alarmist hype). Reading things into an article such as this one is just part of the whole hype thing.
