When it comes to linking power politics, religion and climate change, the Rev. Sally Bingham does not hold back. Hanging prominently in the office of her organization, Interfaith Power and Light, in San Francisco, is a photo of her being arrested at a 2001 protest against drilling in the Arctic National Wildlife Refuge. In the photo, she stares straight at the camera as a police officer handcuffs her. She later described the moment as a "religious experience." Bingham, an Episcopal priest, is using IPL to evangelize churchgoers to take action on climate change.
