Watch Bill Nye Lay Out His Wish List for Saving the Planet

The much anticipated Paris Climate Conference, or COP21, is now past its midway point. The vast majority of the agreement has been negotiated; you can read a draft of the proposal, as it currently stands, online. Over the next two weeks, the leaders of 195 countries need to reach consensus on the critical specifics of the plan, answering questions like: Will we aim to limit warming by 2 degrees Celsius, or by 1.5 degrees? With respect to fossil fuels, will the goal be zero greenhouse gas emissions, climate neutrality or decarbonization?

Or, as scientist and climate activist Bill Nye puts it, “How many Amazon trees for how many tanks of gas?”

Coming off an appearance at the climate march in New York City recently, Nye stopped by the Rolling Stone offices to chat about his new book, Unstoppable: Harnessing Science to Change the World, and to weigh in on the Paris climate talks, among other important issues.

We asked Nye what he’d like to see in the final agreement out of Paris. “By 2050, 100 percent renewable all over the world – we would not be making any more carbon dioxide or methane,” he says. “We would have clean water for everyone on Earth, we would have reliable electricity for everyone on Earth, and we’d have a means to take carbon out of the air.”

You heard the man, climate delegates: Get this done!
