Climate change our most important challenge: Gore - Business LIVE
Climate change is by far the most important challenge that we face and it should be viewed in the context of the way we look at the global economy, says Al Gore, former Vice President of the US and environmental activist.
"India and China have just announced a CO2 tax. I think that's what the world should do. I know it's a hard sell, but as these extreme weather events get the world's attention more - we will get a more spirited debate. We need a price signal so that markets can react."
