Summary
David Boldeman is joined by science journalist Ellen Phiddian to explore a deceptively simple question: how do scientists actually know the oceans are warming? The conversation unpacks the global network of measurements that allow researchers to track heat across the world’s oceans, from early ship-based observations to modern satellite systems and autonomous Argo floats that dive thousands of metres beneath the surface. Along the way, the episode explains why ocean heat content is one of the most important indicators of climate change, how scientists distinguish long-term warming from natural variability, and why the oceans absorb the vast majority of the excess heat in the Earth’s climate system. It is a story about evidence, measurement and the remarkable ability of modern science to take the temperature of a changing planet.
