Do the Math Road Tour

It’s simple math: we can burn 565 more gigatons of carbon and stay below 2°C of warming—anything more than that risks catastrophe for life on earth. But 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.

Based on Bill McKibben’s widely read Rolling Stone article, “Global Warming’s Terrifying New Math,” “Do The Math” aims to raise awareness of the climate crisis and challenge the power of the fossil-fuel industry head-on. Traveling the U.S this fall, founder McKibben brings together a revolving cast of speakers, activists, and musicians—including Naomi Klein, Jim Hansen, Desmond Tutu—in a program designed to inspire people to take action commensurate with the scale of the climate crisis.

The “Do the Math” tour will visit twenty American cities between November 7 and December 3. For more information, please visit
