Allison Chin, president of the Sierra Club, knows now is the moment to think big on climate. It’s been a year of “records”: A record number of droughts have hit towns across the country, record temperatures slowly roast the planet, and storms have left record amounts of snow and rain in their wake. Finally, too, a record number of people concede that we’re changing the environment for the worse. “Mothers, fathers, grandparents, children, businessmen, people of the faith—it’s not just environmentalists that are affected by this,” Chin says. She knows that environmentalists need to be practical—they need concrete demands that all people left adrift by a changing climate can endorse. But facing such long odds and high stakes, how can they be anything but ardent about the environment?
