Corals Remember, Climate Change

In this episode of Three Degrees Apart, I speak with Dr. Kim Cobb, a leading coral climatologist and climate science communicator, about how ancient coral records reveal Earth’s climate history—and what they tell us about today’s rapidly warming world. We explore how corals serve as natural archives of past climate variability, how current rates of warming compare to those in the deep past, and why the pace of change matters so profoundly. Drawing from her fieldwork on remote reefs and her role in global climate conversations, Dr. Cobb reflects on urgency, public understanding, and what it means to balance scientific rigor with hope and action in the face of climate change.
