Earth 2100

History Channel International broadcast, on 12/16/10, a two hour exploration of one possible future; it originally aired on ABC 6/2/09.  Here's the ABC web page and a Wiki page regarding the show.

Many would like to characterize the show as fanciful science fiction or worst case scenario.  If you've read my other posts here, you'd know that I'd say the emphasis on climate change vs. peak oil is all wrong, and hence the situation is much more urgent and dire than portrayed in the piece.

The film does show a population odometer running quickly in reverse around the 3 billion mark.
