US EditionCoral 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 crisis: Coral reefs hit critical tipping point – The Mail & Guardian
The planet has entered a “new reality” as it reaches the first of many climate tipping points: the widespread mortality of warm-water coral reefs, a landmark report has warned. The second Global Tipping Points report, which was released ahead of the COP30 climate summit in Brazil next month, has found that warm-water coral reefs — on which nearly a billion people and nearly a million marine species depend — are passing their tipping point. “Glob…
Scientists warn the planet has crossed its first climate tipping point
Global heating has pushed warm-water reefs past a point of no return, scientists warn, with mass bleaching since 2023 affecting more than four-fifths of reefs and cascading risks for food security, coastal protection, and the global economy ahead of COP30.
The Planet Reached Its First Catastrophic Climate Tipping Point: What Does This Alarming Report Mean
Earth reached its first catastrophic climate tipping point, according to an international report that warns of serious consequences of climate change and global warming for humanity. Prepared by 160 scientists around the world, the paper warns that planet Earth has just undergone a potentially irreversible change for its balance and that it now faces a “new reality” where disasters will become more and more recurrent.The scientific paper was pub…
According to the Global Tipping Points Report 2025, the Earth has left its stable climate phase – first systems are tilting, the consequences are irreversible.
