Coral reefs become first environmental system on Earth to pass climate "tipping point," report says
- On Monday the Global Tipping Points Report said the Earth has reached its first climate tipping point, with warm-water coral reefs now irreversibly destabilised and expected to decline.
- Rising ocean temperatures and acidification have caused coral bleaching and death amid global heating at 1.4°C, surpassing the coral thermal tipping point of 1.2°C.
- About 84% of the world’s coral reefs have bleached in the fourth global bleaching event, threatening ecosystems supporting nearly a billion people and a quarter of marine life.
- Report authors urged governments and negotiators at COP30 in Brazil to act immediately, warning current policy frameworks are inadequate and experts recommend halving emissions by 2030 and net zero by 2050.
- Other systems are nearing dangerous thresholds, including the Atlantic Meridional Overturning Circulation and ice sheets, with scientists urging scaling renewables and carbon removal to avert cascading collapses in the coming years.

Climate prophets say Humanity is entering New Reality — has 'crossed the first tipping point'
With the climate olympic-junket just weeks away in Brazil, the race is on for word-salad-catastrophes flavored with science-incense to shake down more cash and concessions from the rich democracies. And thus the University of Exeter proffers the first round of this year's "on the brink" specials. The first tipping point is almost upon us, just like it was every year for the last 29 years in a row: 'New reality' as world reaches first climate tip…
