Two global meetings are underway: COP26, in which world leaders are meeting to make new goals on addressing climate change, and COP15, the international meeting on biodiversity, where nations are discussing a goal to protect a third of the land and seas. Climate activist Greta Thunberg has criticised the meetings for just being a talk fest. So what's at stake?

In this episode, we speak to Mibu Fischer from the CSIRO who recently published a paper on Indigenous management of the seas as part of the Future Seas project. Mibu explains how Indigenous rights are intimately bound to climate change and biodiversity loss.

Also, Gretta Pecl from the Insitute of Marine and Antarctic Studies at the University of Tasmania, explains how climate change is altering our southern seas, and questions whether simply protecting a third of the oceans is enough.
