I didn't see it, but I remember my professors in college talking about it. "The next ice age is on the way! We're all gonna die!" Now, it's "Global warming is here! We're all gonna die!" Geeze.
When I tease my prof son-in-law about the global warming thing he launches into "Climate Change" mode, a term they invented so that any temperature variation or unusual weather pattern will fit their preferred crisis of the day.
