 I've had a long time to write and speak and think about this gathering climate crisis and in the last few years I've become something of an activist too. Along with my friends at 350.org and with people all over the planet, we've marched and we've rallied. Now we're ready for the most important step yet. Beginning in October, we're traveling across Europe. We're calling this roadshow the Fossil Free Europe Tour. And we'll be doing some math, really the most important math that you'll ever hear. It turns out that the fossil fuel industry has five times more coal and oil and gas in its reserves than even the most conservative governments in the world think would be safe to burn. But they will burn it unless we figure out how to slow them down. That's what this night will be about. It'll be a special evening with the rotating cast of speakers and musicians and video. It'll be interesting, but it'll also be the launch pad of a new kind of movement. One that really offers our last best chance to do something about this gathering crisis. Join us.
