World leaders, scientists and ocean advocates are gathering in Nice for the 3rd UN Ocean Conference (UNOC) and hopes are high that progress can be made on some of the many pressing issues facing our seas - from acidification to pollution, and from biodiversity loss to deep sea mining.

Reporting from the summit, Christiana Figueres and Tom Rivett-Carnac ask: can this moment become a true turning point for ocean governance? Central to the agenda is the High Seas Treaty: a long-awaited international agreement designed to protect marine life in the 64% of the ocean that lies beyond national borders. But with more ratifications needed to get it across the line, can its future be secured while the world’s eyes are on Nice?

Later, Christiana is joined by legendary oceanographer and explorer Dr. Sylvia Earle. Drawing on a lifetime of experience beneath the waves, she shares stories, warnings, and a passionate case for protecting the blue lungs of the planet.

This episode features underwater and ocean recordings taken by sound artist and documentarist Louise Romain.

This November, Brazil will host COP30 in Belém, on the edge of the Amazon rainforest, in what is bound to be a moment packed with symbolism, high expectations, and global significance. This week, Christiana Figueres, Tom Rivett-Carnac, and Paul Dickinson explore what’s at stake, what Brazil wants to achieve, and whether the world is ready to move from ambition to implementation.

Back from his recent trip to the country, Tom shares conversations with COP CEO Ana Toni and Gustavo Westmann from the office of the Brazilian Presidency, along with insights and impressions he picked up on the ground - from the growing political momentum to the logistical and diplomatic hurdles still to be overcome. Plus, he introduces the team to the concept of mutirão - this COP’s ambition that the path to climate action be built collectively, and through shared effort, cooperation, and solidarity.

With Brazil readying itself to be the focus of the world’s media later this year, we ask: can COP30 be a breakthrough moment for fossil fuel phaseout, nature protection, and delivery on past promises? Or will it risk becoming another high-profile summit weighed down by old divisions and new distractions?
