Who's the hero that will protect us from the impact of extreme heat, rain and whatever else climate change might throw at us in future? Forget someone in a cape, maybe it's the person quietly sketching buildings on a bit of paper.
Architects shape the buildings we live in and rely on - can they change the way they work to make sure that our homes are smart enough to outpace the challenges of climate change? And can they lead the way in cleaning up the impact of the building industry? Or is the challenge just too great?
We find out with the help of:
- Isabel Allen, editor of Architecture Today
- Barnabas Calder, reader in architecture at the University of Liverpool
- Jay Morton, director of Bell Phillips Architects and incoming President Elect of RIBA
With thanks to Jess Hrivnak, and Melissa Mean and Jasmine Tippett from WeCanMake.

Helen Czerski and Tom Heap discover how new technology lets us listen in to the extraordinary sounds of the planet's waterways. From the deepest ocean to the tributaries, rivers and streams, this is an exploration of the sound made under water by animals, humans, and yes even plants. From the snapping of shrimp to the bark of a John Dory, Tom and Helen ask how sound travels through water, how important it is and what is known about the purpose of these sounds. They also ask what impact human activity is having on the watery soundscapes and their inhabitants. Joining Tom and Helen are Marine Biologist Steve Simpson, Former Submariner Bob Mansergh, Principle Scientist Rosalyn Seddon and Eco-Acoustician Jack Greenhalgh.

Is there any true wilderness left on our planet? Tom Heap and Helen Czerski consider the fear and fascination of the wild. They're joined by the writer Cal Flyn who has spent the last few years travelling the world in search of wilderness for her new book The Savage Landscape. Also with them are Steve Carver, professor of Rewilding and Wilderness Science at Leeds University and Sophie Grig, Research and Advocacy Director of Survival International.
The travel writer and broadcaster Antonia Bolingbroke-Kent escapes the studio to visit the largest rewilding project in Wales. Can the conservationists get local people onside and boost the area's wildlife without provoking a negative reaction from local farmers?

How can Britain- and the world- prepare itself for extreme heat? Tom Heap and Helen Czerski hear from the experts and from the people facing up to the hottest temperatures on the planet.
David Shukman, former BBC Science Editor asks how Britain should react to the threat in his new book, The Response, while Alex Riley, author of Super Natural guides us through the strategies used by animals that thrive in the hottest places on Earth. Tom and Helen are also joined from Bangalore by Chandni Singh of the Indian Institute for Human Settlements who shares her knowledge of the Indian response to heatwaves that can push the mercury to 48 degrees centigrade and make human life impossible to sustain.
