Earth the Owner's Manual

I have it on good authority that this is going to be great.

Jeff Masters has a writeup.

Penn State climate scientist Dr. Richard Alley hosts parts II and III of Earth: the Operator's Manual on PBS beginning at 7pm Sunday, April 22--Earth Day. Part I of this excellent series aired in April 2011. The series gives an overview of climate change, but primarily focuses on what we can do to help slow down climate change though smart energy choices....

I've seen some bits and pieces and it looks good.
