Earlier this week the deadly Mediterranean cyclone, Storm Daniel, swept through the small city of Derna in Libya, collapsing a 50-year-old dam in its wake, and triggering devastating floods which have killed over 5000 people. We speak to atmospheric scientist, Stavros Dafis, about the cyclone鈥檚 characteristics and to civil and structural engineer, Lis Bowman, about the dam collapse. Unsurprisingly, it all comes back to climate change.

Far, far from Earth, the James Webb Space Telescope has set its site on the atmosphere of exoplanet K2-18b where the presence of methane and carbon dioxide offer the tantalising possibility of an extraterrestrial Ocean. Astrophysicist Nikku Madhusudhan discusses his exciting results.

And an even less expected presence in space: the ancient remains of our ancestors. Archaeologist Lee Berger has come under fire after sending precious bone samples on a Virgin Galactic space flight. South African archaeologist, Robyn Pickering, expresses the frustration that is on everyone鈥檚 mind.

Also expressing their anger, two young climate protesters recently stormed the stage during an orchestral performance at a Swiss music festival. But, to everyone鈥檚 surprise, conductor Vladimir Jurowski allowed them to speak to his audience. We hear from the Renovate Switzerland protestors, Anthony and Selina, on their unlikely experience.
