Can humans survive a future of extreme heat?

Can humans survive a future of extreme heat?

Author: ARC Centre of Excellence for 21st Century Weather December 4, 2025 Duration: 1:21:57

Can the human body survive climate change? That’s the burning question in this episode of Totally Cooked. With the world already experiencing more frequent and intense heatwaves, we sit down with Professor Ollie Jay from the University of Sydney to explore how our bodies respond to extreme heat, and what happens when they can’t keep up.

Ollie walks your co-hosts Professor Sarah Perkins-Kirkpatrick and Iain Strachan through the science of sweating, hydration, and heat stress, and explains the critical tipping points between heat exhaustion and deadly heatstroke. We discuss who’s most at risk, why heat is often overlooked as a killer, and what governments, communities and individuals can do to stay safe in a hotter world. We also find out what it’s like to sit in a room set to 54°C, and why your fan might not be helping as much as you think.

Plus, it’s quiz time: from Death Valley to the Ashes, the FIFA World Cup to the Sahara, we put Sarah and Ollie to the test with a scorcher of a quiz on record-breaking heat. If you’ve ever wondered whether climate change is cooking us alive (and how long we can keep turning up the thermostat) this episode has the answers.

Iain records Totally Cooked on the lands of the Bunurong People of the Kulin Nation. Sarah records Totally Cooked on the lands of the Ngunnawal and Ngambri people. We pay our respects to Elders past, present and emerging and recognise their unique and continuing connection to the land, skies, waters, plants and animals.

Ever feel like the weather forecast is just the opening act for a much bigger, more urgent story? That’s the space where Totally Cooked: The Climate & Weather Podcast lives. Guided by Professor Sarah Perkins-Kirkpatrick, a climate scientist who studies extreme heat, and Iain Strachan, a journalist who translates complex science, this conversation pulls apart the daily headlines and the long-term trends. They connect the dots between a specific storm, a record-breaking heatwave, and the broader shifts in our global climate system. The discussion isn’t just about melting ice caps far away; it’s about what changing weather patterns mean for health, fitness, and daily life, particularly in the Australian context where the effects are often felt first and hardest. This podcast from the ARC Centre of Excellence for 21st Century Weather moves beyond alarmism into grounded, evidence-based exploration. You’ll hear clear explanations of the physical mechanisms driving our weather, frank assessments of risks, and thoughtful conversations about adaptation, all delivered with a relatable dynamic and the occasional necessary dash of dark humour. It’s for anyone who wants to move past the soundbites and understand the real-world implications of a planet that’s, well, totally cooked.
