Thirty-four years ago, the United Nations Framework Convention on Climate Change (UNFCCC) established the annual “conferences of the parties,” known as COPs, where almost every nation on earth comes together to negotiate a solution to climate change. But this past November, for the first time ever, the United States did not send a delegation to COP, and this month, the Trump Administration announced its intention to withdraw from the UNFCCC entirely. Lina Yassin has been to nine COPs, including the most recent, COP30, in Brazil. Originally from Sudan, Lina provides support for some of the world's poorest and most climate-vulnerable nations at these negotiations. She joins Amy to talk about what happened at this year’s conference, and why, despite the U.S. withdrawal, she believes it’s essential to keep this multilateral process alive.
