"Today we use 100 million barrels of oil every single day. There are no rules to keep that oil in the ground. The rules have to be changed. For 25 years, countless of people have stood in front of the United Nations asking our nations’ leaders to stop the emissions. But clearly this has not worked, since the emissions just continue to rise. So I will not ask them anything. Instead, I will ask the people around the world to realize that our political leaders have failed us, because we are facing an existential threat and there is no time to continue down this road of madness."
