Former US Vice President Al Gore is known to many as the Paul Revere of climate change, alerting the world to the dangers of a warming planet and other "inconvenient truths" at a time when only 2/5 Americans were onboard with his message. It earned him a Nobel Peace Prize.

But today, Al Gore has good news to share. In a wide-ranging interview with Ian Bremmer on the sidelines of the World Economic Forum in Davos, Gore is clear-eyed but optimistic about our climate future.

"If we get to true net zero and stop incrementally adding to the amount of heat-trapping gas that's there, the temperatures will stop going up almost immediately with a lag of as little as three to five years. Now, that's new science. It's well-confirmed now. They used to believe that it would keep going even after we reach net zero, but no, it will not. The even better news is that if we stay at true net zero, then half of all the human-caused CO2 and methane will fall out of the atmosphere in as little as a quarter of a century."
