Pope Francis says he will attend the COP28 climate conference in Dubai next month, which would make him the first pontiff to attend the annual UN gathering. The pope has made addressing the climate crisis an important focus since 2015, when he published an encyclical on climate change and the environment. Last month, he doubled down on his stance with a new document – Laudate Deum. It's a scathing rebuke of the inaction by world leaders over the last eight years. As Francis takes on an even bigger role in climate activism. What does he hope to achieve? And how does this all fit into his broader legacy as leader of the world's 1.3 billion Roman Catholics. NPR's Scott Detrow spoke with Fordham professor Christiana Zenner, and Associated Press Vatican correspondent Nicole Winfield, about Pope Francis and his role in advocating for action on climate change.
