Watch: Do the Math

The grassroots movement to solve the climate change crisis,, has launched a 21 city tour with a power ally, math. The Do the Math Tour, is headlined by author-activist Bill McKibben, who will be joined by a rotation of committed artists, actors, and musicians to deliver an important message:

It’s simple math: we can burn 565 more gigatons of carbon dioxide and stay below 2°C of warming — anything more than that risks catastrophe for life on earth. The only problem? Fossil fuel corporations now have 2,795 gigatons in their reserves, five times the safe amount. And they’re planning to burn it all — unless we rise up to stop them.
