US EditionScientists Sound Alarm: Earth Has Surpassed Its First Climate Tipping Point
Rising ocean temperatures have caused repeated mass bleaching, stressing 84% of tropical coral reefs and pushing them past their thermal tipping point, scientists report.
- The Global Tipping Points Report finds the authors warn tropical coral reefs have already crossed a climate tipping point, risking irreversible damage.
- Scientists say current global warming of about 1.4°C already exceeds corals' thermal tipping point of about 1.2°C, causing repeated mass bleaching and unprecedented coral mortality.
- The last two years were the warmest on record, with marine heatwaves stressing 84% of the world's reefs and threatening a quarter of marine life.
- At COP30 next month, scientists implored countries to reduce carbon emissions as the report warns polar ice sheets may have passed tipping points, risking several meters of irreversible sea level rise.
- The authors project global average temperatures will climb to 1.5°C within the next few years, raising the chance additional tipping points could soon be crossed.

World’s coral reefs near irreversible die-off, scientists warn | Honolulu Star-Advertiser
COPENHAGEN, Denmark >> Global warming is crossing dangerous thresholds sooner than expected with the world’s coral reefs now in an almost irreversible die-off, marking what scientists on are describing as the first “tipping point” in climate-driven ecosystem collapse.
While global warming is dangerously close to the 1.5 °C threshold, climate and nature are crossing critical thresholds faster than expected. The most dramatic indicator of this crisis is the world's coral reefs, which have entered a phase of almost irreversible extinction.
Scientists Sound Alarm: Earth Has Surpassed Its First Climate Tipping Point
The 2025 Global Tipping Points Report warns that preventing the widespread die-off of coral reefs will now require immense effort. In a new report released on October 13, 2025, a team of international climate scientists warns that saving tropical coral reefs from destruction caused by rising ocean temperatures will now require extraordinary global effort. The [...]
Global Tipping points: A moment that demands not despair but mobilisation
We are standing at a tipping point – but we also stand at the edge of a powerful opportunity. The same science that warns us also guides us. Coral reefs have not given up – and neither should we. The recent Global Tipping Points Report paints a sobering picture: warm-water coral reefs, lifelines for nearly a billion people and home to a quarter of all marine species, are passing a dangerous threshold. As the planet warms, these vibrant ec…
The world’s tropical coral reefs almost certainly crossed a point of no return at which they will not be able to survive the warming of the oceans, warned a scientific report released on Monday. It is the first time that scientists declare that the Earth would have reached the so-called “flip point”, a turn that can trigger massive and sometimes permanent changes in nature. “Sadly, we are almost certain that we crossed one of those tipping point…
Global warming continues to alter the state of our planet. In one study, researchers observed an unprecedented decline in coral reefs. Why is this new climate tipping point so worrying? The "unprecedented" decline of coral reefs is affecting "the livelihoods of hundreds of millions of people who depend on them" and the survival of one million marine species.
