Carbon capture is the talk of the climate scene right now. That’s technology that removes planet-warming carbon dioxide from the air and sequesters it in the Earth. President Joe Biden on Earth Day laid out a vision of net zero emissions by 2050 that relies partly on carbon removal. Also, Elon Musk last week officially launched a $100 million XPrize to fund carbon capture tech. Australia plans to spend more than $400 million on it, too. But climate scientists say carbon capture risks making us think we can just keep emitting all we want. Molly speaks with James Dyke, a senior lecturer in global systems at the University of Exeter, who recently wrote about this in the Conversation. He said there’s another big problem with carbon capture and storage: It doesn’t exist at scale.
