Diagram illustrates that warm water coral reefs are the first of the global tipping points to be reaching tipping point temperatures. The authors comment that “Every tipping point of danger can be mirrored by a tipping point of opportunity. If coral reefs are dying back, restoration of coastal ecosystems can still drive
resilience and livelihoods.”

From the Global Tipping Points Report 2025 issued at www.global-tipping-points.org, Oct 13, 2025:
“The world has entered a new reality. Global warming will soon exceed 1.5°C. This puts humanity in the danger zone where multiple climate tipping points pose catastrophic risks to billions of people. Already warm-water coral reefs are crossing their thermal tipping point and experiencing unprecedented dieback, threatening the livelihoods of hundreds of millions who depend on them. Polar ice sheets are approaching tipping points, committing the world to several metres of irreversible sea-level rise that will affect hundreds of millions.”
