Gore Launches Major Climate Campaign

Al Gore just launched a $300 million, 3-year campaign to educate Americans on global warming with the Alliance for Climate Protection. Online ads and TV ads during prime shows like American Idol and the Daily Show will be major elements.

Why now? Gore sees that politicians on both sides of the aisle are moving too slowly to cut global warming emissions. He wants to push the US to implement a national carbon cap and ratify a global agreement on emissions in the next three years.

"It's important to change the light bulbs, but it's much more important to change the laws," he said.
