The latest episode of the University of Liverpool’s Original Ideas podcast explores the growing impact of heatwaves and the research helping communities respond to one of the world’s most dangerous natural hazards.
Heatwaves are becoming more frequent and intense due to climate change, placing increasing pressure on health systems, infrastructure, and vulnerable communities around the world. The episode examines how Liverpool researchers are investigating the social, historical, and public health dimensions of extreme heat and exploring ways cities can better adapt.
The University of Liverpool’s Melting Metropolis research is a major Wellcome funded project that explores how people experience urban heat, and how cities can respond. It brings together historians, artists, and community engagement experts to better understand heat and health in London, New York, Paris and beyond.
Professor Chris Pearson, Environmental Historian and Principal Investigator on the project, and Dr Anna Bocking-Welch, Senior Lecturer in History, join host Gavin Freeborn to talk about the realities of extreme heat, and what cities can do next.
The clips are John Nairn, Senior Extreme Heat Advisor, World Meteorological Organization talking at a UN (United Nations) conference, and Dr Chloe Duteil, Melting Metropolis, University of Liverpool.
With work spanning climate history, urban environments, and public health, the discussion highlights how heat can disproportionately affect vulnerable groups, particularly in densely populated urban areas where the “urban heat island” effect can intensify already dangerous temperatures.
The episode also considers how historical experiences of heat can shape present-day policy and planning, from housing and public spaces to healthcare and community resilience.
Heat is one of the deadliest consequences of climate change, yet its impacts are often underestimated compared to other natural hazards. Researchers in the episode discuss the importance of interdisciplinary approaches to understanding how societies can adapt to rising temperatures while protecting those most at risk.
The Original Ideas podcast showcases the breadth of research taking place at the University of Liverpool and its real-world impact. Hosted by Gavin Freeborn, the series explores major global challenges through conversations with academics, students, and partners working to shape a better future.
