Two former GOP governors, John Kasich from Ohio and Arnold Schwarzenegger from California—who together with former U.S. Senator and Secretary of State John Kerry co-founded World War Zero, a nonpartisan, nonprofit organization intended to bring people of diverse backgrounds together to fight climate change—convened a town hall meeting at Otterbein University in Ohio on Sunday.

“Do we have to have a revolution? No, but I don’t think we can just sit around and wait,” Kasich said. “I don’t think we’re making the kind of progress we ought to make.”

“It is not a party issue because there’s no Democratic air or Republican air…We all breathe the same air,” Schwarzenegger added. “It’s no different than promoting fitness. The more you talk about it, the more is going to happen. And the more you’re going to go and get everyone on board, but what we want to do is to really teach ordinary folks, what can they do to participate in this whole thing,” Schwarzenegger told The Dispatch. “This is what this town hall meeting is really about.”

Nearly 100,000 people have pledged to be part of the World War Zero campaign.
