This November, Bill McKibben and 350.org are embarking on a nationwide trek -- the Do the Math Tour -- that will explain the scary math of climate change, and lay out the plan to take on the fossil fuel industry before they trade away our future for a quick buck.

On Nov. 18th, Bill and the tour will stop by Washington, DC for a Sunday afternoon event in partnership with the Chesapeake Climate Action Network. There will be music and special guests both in person and via video, plus all of the best climate organizers in and around DC.

Please join us on November 18 to lay the groundwork for the next phase of the climate movement in our region and nationally. As the math gets scarier, we're kicking our movement into an even higher gear to confront the fossil fuel industry and create a livable future for our planet.
