Coral reefs face catastrophic collapse. Thermal tipping points for widespread, irreversible dieback have already been passed at 1.2–1.4°C of global warming. The ocean is already 30% more acidic since the Industrial Revolution began, weakening coral reefs growth – akin to the osteoporosis of the sea.
Unless we reduce global emissions at extraordinary speed and scale mass restoration with thermal resistant coral resilient to increasingly acidic waters – the future is dire: at 1.5°C, we lose 70-90% of reefs; at 2°C: 99% destruction.
