Al Gore's 24-hour climate party

Can Elton John and Jon Bon Jovi save the world from global catastrophe? Al Gore thinks so.

The former vice president is starting a 24-hour telethon of sorts Friday afternoon, called "24 Hours of Reality and Live Earth: The World is Watching." Its focus: to raise awareness about climate change ahead of the Nov. 30-Dec. 11 United Nations conference on climate change where President Obama wants to sign a global deal on cutting greenhouse gas emissions.

Gore, a long-time global warming activist, is raising the specter of danger to drive concern, given his past attempts at raising awareness with the documentary "An Inconvenient Truth." The U.N. "climate talks can be a breakthrough moment to change the dangerous course we've set for our planet," Gore said. "We want the world's leaders to know the world is watching, and it's time for them to act."

Its also a perfect fundraising opportunity for Gore's activist group Climate Reality Project, which is organizing the event. "Help us educate the public and power a global grassroots network devoted to solving the climate crisis," the event's website reads after clicking the donate tab.
