This episode explains how sea level rise is measured — not just that it’s happening. It demystifies the tools, the data, and the validation process that sit behind one of the most talked-about climate metrics.
Sea level is a baseline measurement that underpins city planning, infrastructure design, flood risk modelling, and long-term coastal decision-making. Understanding how we know builds trust in what we know.
Science journalist Ellen Phiddian joins host David Boldeman to guide you through the measurement process, how evidence is tested, and how journalists assess confidence in scientific claims.
