ARC - Climate change is flooding the Arctic Ocean with light – what it means for the species that live there

This is a transcript of episode 5 of The Conversation Weekly podcast, How climate change if flooding the Arctic Ocean with light. In this episode, two experts explain how melting ice in the far north is bringing more light to the Arctic Ocean and what this means for the species that live there. And we hear from a team of archaeologists on their new research in Tanzania’s Olduvai Gorge that found evidence of just how adaptable early humans were to the changing environment.

Dan Merino: Hello and welcome back. From The Conversation, I’m Dan Merino in San Francisco.

Gemma Ware: And I’m Gemma Ware in London and you’re listening to The Conversation Weekly, the world explained by experts.

Dan: In this episode, two Arctic Ocean researchers explain how melting ice in the far north leads to more light in the Arctic – and what that means for sea life.

Karen Filbee-Dexter: Our ecosystems are responding, because these changes are really dramatic and they’re noticeable.

Gemma: And we talk to a team of archaeologists about the early humans who lived in Tanzania’s Olduvai Gorge 2 million years ago.

Makarius Peter Itambu: In this scenario, hominims from Oldupa maintained the very same toolkit.

Dan: So Gemma, today we’re going on a journey up to just about as far north as we can go, all the way up to the Arctic. What do you imagine when I say the word Arctic?

Gemma: I feel a bit cold already, and I guess I think of big expanses of snow and ice, drifting, like wind. Maybe the odd polar bear. And I guess in winter it’s just dark.

Dan: That’s a great example if you were to stay on top of the ice, but there’s a whole different world beneath it. And it’s full of ocean, like teeming alive.
