Coral Reefs and Seaweed Overgrowth

In this episode, Prof. Marten Scheffer from Wageningen University & Research explains critical transitions and tipping points, from shallow lakes and coral reefs to tropical rainforests. Together with host Dr. Volker Hahn, he explores whether local tipping points can be scaled up to a biospheric planetary boundary, and how uncertainty shapes our understanding and communication. Scheffer explains why he believes the concept of tipping points remains relevant for policy and management—even when we do not know where they lie.
