Scientists studying whales are uncovering new clues about how the ocean stores carbon — and what climate change is doing to marine ecosystems.

From the food they eat to where their waste and bodies end up, whales help move carbon from the surface ocean to the deep sea, where it can be locked away for centuries. Their presence can shape entire marine ecosystems, influencing how much carbon the ocean absorbs from the atmosphere.


In this episode of The Climate Question, Graihagh Jackson and Jordan Dunbar explore what whales can tell us about climate change — and how warming oceans may be affecting them in turn.

Graihagh and Jordan speak to Victoria Gill, BBC Science Correspondent, about new research analysing Antarctic seabed samples to trace how whale populations influence long-term carbon storage.

And Helen Czerski, physicist, oceanographer and author of Blue Machine: How the Ocean Shapes Our World, explains one of the most unexpected scientific records of all: whale earwax — and how it reveals their stress levels in a changing ocean.
