Al Gore sounds the alarm on global waming

The former Vice President appeared on Oprah to talk about the message from An Inconvenient Truth:

Gore was in Franklin, Wisconsin on Sunday, filming a spot for the show that will highlight things people can buy for the holidays to help the environment, said Gore spokeswoman Kalee Kreider.

Gore took a film crew into the Franklin Lowe's Home Improvement store, where he suggested purchasing a programable thermostat, compact fluorescent light bulbs and energy efficient appliances.

"It's exciting to have Mr. Gore at our store," said manager Jeff Willis. "And it's good that he's helping people save on their energy bills."

His appearance included numerous excerpts from the slideshow, either presented live by Gore or in clips from the documentary.
