The world isn’t on track for the worst-case climate scenario anymore—but that doesn’t mean the future is safe. In this episode, climate scientist Katharine Hayhoe explains how human decisions are the biggest source of uncertainty in climate projections, and why our choices still matter. Progress is real—but so is the risk of stopping short.
