Coral reef events at UNFCCC COP30

The 30th United Nations Climate Change Conference (COP30), scheduled for November 10–21, 2025, will take place in Belém, Brazil. It will serve as a pivotal moment for global climate action, focusing on negotiations for climate finance, emissions reductions, and adaptation, and will accelerate progress toward the goals of the Paris Agreement. The conference will bring together world leaders, policymakers, scientists, and civil society to focus on translating climate pledges into action.

Coral reefs exist in over 100 countries and territories, underpinning Earth’s vast marine biodiversity. They provide ecosystem services worth up to $9.9 trillion USD annually and support the livelihoods, well-being, and cultures of nearly 1 billion people.

Yet their survival is threatened by increasing local pressures, compounded by the escalating climate crisis. The ongoing fourth global bleaching event – the most widespread and severe on record – has impacted over 84% of reefs worldwide.

The 2025 Global Tipping Points Report warns the world has passed its first climate tipping point: warm-water coral reefs.

Still, pockets of reef resilience remain. This moment demands not despair, but mobilisation.
