Al Gore has spent the last two decades fighting for climate action and encouraging the United States and other countries to take meaningful steps in mitigating greenhouse gas emissions. He sat down with Fast Company’s Adele Peters to discuss the intricacies behind the effort, his new movie An Inconvenient Sequel, and the best way to make a difference in combatting climate change.

Gore firmly believes that the threat of climate change will make itself clear, which will catalyze a large-scale movement to combat the effects. But the former congressman and Nobel Peace Prize winner seeks to prevent these climate disasters from happening. Even in the face of an administration that wants to revive the fossil fuel industry, Gore sees hope and momentum in the fight against global warming.
