Bad Idea #6 "We can still save the arctic" with Julienne Stroeve

🔍 Episode Summary:

What if the bad idea… is thinking we can still save the Arctic?In this sobering but illuminating conversation, Mark Lynas speaks with renowned polar climate scientist Julienne Stroeve to explore one of the most consequential but misunderstood climate tipping points: the melting of the Arctic.

Together, they unpack the science behind sea ice loss, permafrost thaw, Greenland melt, and the feedback loops that could push the climate system toward runaway warming. Julienne, who has spent decades conducting fieldwork and analysing satellite data, explains why the idea that we can still "save" the Arctic is, sadly, a myth — and what that means for global sea level rise, extreme weather, and the fate of species like polar bears.

From icebreaker expeditions to geoengineering schemes, this episode takes you to the frontlines of a rapidly disappearing world.

🧠 Topics Discussed:

• 🧊 Why the Arctic sea ice is already committed to disappearing in summer

• 📉 The science behind Greenland’s melt — and how fast it’s accelerating

• 🌊 Sea level rise: how much, how soon, and where it hits hardest

• 🐻 Polar bears, permafrost, and the myth of adaptation

• 💣 The risk of tipping points and feedback loops (albedo, methane, etc.)

• ❄️ What past interglacial periods tell us about a future without Arctic ice

• 🌍 Why what happens in the Arctic doesn’t stay in the Arctic

• 🌀 Jet streams, polar vortexes, and extreme weather in a warming world

• 🧪 Geoengineering: what might work, what probably won’t

• 🛰️ The role of satellites and field data in improving climate models

• 🇺🇸 The growing threat of political interference with science in the US
  

👩‍🔬 Guest Bio:

Dr. Julienne Stroeve is a polar climate scientist and professor currently affiliated with the University of Manitoba and University College London. Her work focuses on satellite remote sensing, Arctic sea ice, climate modeling, and the impacts of climate change on polar systems. She has participated in numerous field expeditions, including the landmark MOSAiC expedition, and is one of the world’s leading experts on Arctic cryosphere dynamics.
