Earth 'squeezed like an orange': Call for climate action

Celebrities from filmmaker Ava DuVernay to Britain's Prince William to the Pope himself issued powerful calls Saturday calling for people to mobilize and unify to confront the climate crisis.

-- US economist Rebecca Henderson

"The fossil fuel industry knows how to stop global warming, but they are waiting for someone else to pay and nobody is calling them out on it."
