In this episode of Totally Cooked: The Climate & Weather Podcast, hosts Iain Strachan and Professor Sarah Perkins-Kirkpatrick sit down with one of the world’s most recognisable climate communicators: Professor Ed Hawkins from the University of Reading. Ed is the climate scientist behind the now-iconic Climate Stripes, a deceptively simple graphic made of blue and red bars that tells the story of global warming at a glance. First published in 2018, the stripes visualise more than a century of rising global temperatures, with each stripe representing the average temperature for a single year and shifting from cooler blues to warmer reds as the planet heats up.

The Climate Stripes have travelled far beyond academic journals. Downloaded more than a million times within days of their public release, they’ve appeared everywhere from social media campaigns and fashion to projections on famous landmarks, helping people around the world understand climate change without needing a single axis label or number. In this conversation, Ed explains how the idea emerged from a desire to communicate climate data more clearly, why the stripes resonated so strongly with the public, and how visualisations like the climate spiral (another of his widely shared creations) can make complex science instantly understandable.

But this episode goes beyond the stripes. Ed also discusses his research into climate variability and extreme weather, his work with the UK’s National Centre for Atmospheric Science, and the Weather Rescue citizen science project, which recruits volunteers to digitise historical weather records from handwritten archives. Together, these efforts help scientists extend the climate record further into the past, giving us a clearer picture of how quickly our climate is changing, and why communicating that change effectively matters more than ever.
