Looks like Oprah and Leo aren’t the only celebs concerned about climate change. This week (Wednesday, Nov. 2, 8-9 PM ET/PT), Alanis Morissette will host and narrate a PBS documentary on global warming:

International recording artist Alanis Morissette hosts and narrates a one-hour PBS network prime time documentary on global warming, people across America facing the possibilities of grave consequences of a changing climate, and the innovative individuals, communities, and scientists creating new approaches to safeguard our children’s future. Filmed across the U.S., Asia, and South America, this accessible, empowering program brings the reality of climate change to life and offers viewers ways to make a difference in their own communities. See what’s melting, what’s rising, what’s drying up, and what’s drowning … and how school kids, county sheriffs, architects, and community planners are taking action.

You can watch a two-minute preview of the doc here [20MB MPEG] or a smaller promo [3MB MPEG] at www.alanis.com.
