U.S. climate envoy John Kerry is Michael Schmidtpreparing for the next major climate summit, in Dubai. He's calling for an end to permitting new, unabated coal-fired power anywhere in the world. We ask him about whether the U.S. has lived up to its climate commitments.

We also talk to Vox climate reporter Rebecca Leber about Biden's signature climate legislation, which was passed a year ago this month.
