Coral reefs suffering from climate change are no longer a warning for the future, they are happening now. A landmark scientific report reveals that warm-water reefs have already passed a tipping threshold due to global heating, leading to widespread die-offs and threatening the biodiversity and coastal protection they provide. For the millions of people who depend on reefs for food and livelihoods, this is not just an ocean issue but a global crisis.

Global heating is pushing other critical systems — from ice sheets to the Amazon rainforest to the Atlantic Ocean circulation — closer to collapse. The danger is not only ecological, but social and economic, with cascading impacts on communities worldwide. Yet the report also emphasizes the possibility of positive tipping points: rapid shifts in renewable energy, sustainable practices, and collective action that could steer us toward a safer future.

In this episode, Andrew Lewin connects the science to lived experiences as a marine biologist and ocean communicator. He shares what these findings mean for the future of coral reefs, why every fraction of a degree of warming matters, and how each of us can contribute to turning the tide.
