These days, with the world divided as it is, it’s hard to imagine more than 195 countries coming together to reduce greenhouse gas emissions. Yet that’s precisely what happened in 2015 with the Paris Climate Agreement. The accord was a historic deal, but what do we really know about how it was reached? 

On the first episode of The Negotiators, we hear from Tom Rivett-Carnac, who helped bring countries together in Paris. Rivett-Carnac began his adult life as a Buddhist monk and eventually became the senior advisor to Christiana Figueres, who helmed the U.N. talks that led to the climate agreement.
