Join hosts Sarah Perkins-Kirkpatrick and Iain Strachan as they welcome historical climatologist Dr Linden Ashcroft and PhD candidate Ruchit Kulkarni, both from the University of Melbourne. This ep the panel dig through diaries, ship logs and colonial era weather stations in search of Australia's climate before the instrumental record began. What counts as a reliable weather observation from 1830? Why does a reference period matter for understanding today's extremes? And why is the Southern Hemisphere's climate history so much thinner than the Northern Hemisphere's? The episode traces how pre-Bureau of Meteorology data, from convict-era rain gauges to a lighthouse keeper's logbook on Gabo Island are rescued, digitised and quality-checked before it can be trusted.

Deadly droughts, time-series analysis, historical data in research and the beauty of stories that stood the test of time and science. All part of this cooked up ep going back in time. So dust off the family diaries and tune in as Totally Cooked goes looking for Australia's climate in the historical record — and asks what two centuries of old numbers can tell us about the droughts and floods still to come.

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.

Cities are where so many of us really experience climate change. They’re where heatwaves keep us awake at night, where flash floods turn streets into rivers, and where concrete, glass and asphalt can reshape the weather around us. As more than half of humanity now lives in urban areas, the story of climate change is increasingly a story about cities - how they amplify extremes, how they trap heat, and how smart planning might help protect the people who call them home.

In this episode of Totally Cooked, Sarah and Iain are joined by Associate Professor Negin Nazarian, and PhD student Ressy Fitria. They're hitting the streets to explore the science of urban climate. What exactly is an urban heat island? Do cities just experience climate change, or do they actually modify the climate themselves? And how well are our climate models capturing the complexity of real neighbourhoods?

We’ll also head to Indonesia, where a brand new capital city is rising in tropical Borneo. As Jakarta sinks and sea levels rise, Nusantara is being billed as a 'smart forest city' built for the future. But what happens to heat, humidity and extreme weather when you replace tropical forest with high-density urban development? And can we truly design cities that work with the climate, rather than against it?
