Actors and rock stars are throwing their weight behind the battle against global climate change. The movement Global Cool—backed by the likes of actors Leonardo DiCaprio and Orlando Bloom and rock bands Coldplay and the Killers—hopes to get 1 billion people to cut their carbon emissions by 1 metric ton a year for the next decade. Some climatologists believe that a climactic “tipping point”—when apocalyptic change becomes unstoppable—can be averted if the world reduces greenhouse-gas emissions by 1 billion tons a year. The group’s Web site, www.Global-cool.com, offers tips such as showering with a friend to save hot water and unplugging cell phone chargers to save electricity. A U.N. report due out this week is expected to predict an inevitable rise in sea levels due to the melting of glaciers and sea ice.
