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.
Global warming will soon exceed 1.5°C, putting humanity in the danger zone where multiple climate tipping points pose catastrophic risks to billions of people.
The second Global Tipping Points report, released ahead of the COP30 climate summit in Brazil, found that warm-water coral reefs are passing their tipping point, affecting nearly a billion people and nearly a million marine species that depend on them.
A report produced by 160 authors from 23 countries warns of catastrophic harm unless humanity takes urgent action.
