One thing that Gore's speech didn't repeat, however, was a call he made in Oslo on Sunday for a "people power" movement to help reverse climate change.
Gore said such a movement would put pressure on those in political power to adopt concrete measure to cut carbon emissions.
"As the truth of this climate crisis becomes known, the world will demand action," Gore said during a press conference at the Nobel Institute in Oslo.
He noted that many local efforts are being made, citing emissions cuts programs in California and decisions by 700 US cities to embrace international protocols proposed in Kyoto -- despite a refusal in Washington to sign the Kyoto agreement. Conservation measures by individuals are also important, but it will take laws and treaties to make the necessary impact, Gore said.
Pachauri said the actual costs of mitigating climate change aren't as high as many might think, especially if they're taken during the next seven years before the consequences of global warming become irreversible. Nor, he said, do emissions control measure need to halt economic growth.
