"Make peace with the planet," Gore says in accepting Nobel

Calling on the world to declare war on global warming, former Vice President Al Gore accepted the 2007 Nobel Peace Prize in Oslo, Norway, on Monday.

He shared the prize with Rajendra Pachauri of the United Nations Intergovernmental Panel on Climate Change, recognized for its work alerting the world to the imminent threats of climate change.

The ceremony also put a spotlight on work being done by scientists and world leaders in Bali, Indonesia, now hammering out a post-Kyoto Protocol framework to address global warming, as well as a climate-change bill now being considered by the U.S. Senate.

Gore and Pachauri will leave Wednesday for the Bali meeting.

"It is time to make peace with the planet," Gore said in his acceptance speech. "We must quickly mobilize our civilization with the urgency and resolve that has previously been seen only when nations mobilized for war."

Gore and Pachauri received their Nobel gold medals and diplomas at a gala ceremony at Oslo's City Hall, while the Nobel Prizes for medicine, chemistry, physics, literature and economics were presented in a separate ceremony in Stockholm, Sweden.

The 2007 awards in medicine, chemistry and physics honored breakthroughs in stem-cell research on mice, solid-surface chemistry and the discovery of a phenomenon that lets computers and digital-music players store reams of data on ever-shrinking hard disks.

Three U.S. economists shared the economics award for their work on how people's knowledge and self-interest affect their behavior in the market or in social situations such as voting and labor negotiations.

One of the economics winners, Leonid Hurwicz, 90, and the literature prize winner, 88-year-old British author Doris Lessing, were unable to attend.
