Earth hits first climate ‘tipping point’ as coral reefs face collapse, landmark report warns

Humanity has pushed the planet into a “new reality,” scientists warn, as rising temperatures trigger the first major climate tipping point — the mass death of coral reefs.

A report by 160 scientists finds that coral reefs are collapsing under record ocean heat, marking the first irreversible shift in Earth’s climate systems. More than 80% of reefs are affected, threatening marine life, food security, and coastal protection.

The study warns other tipping points could soon follow, including the potential collapse of the Atlantic Meridional Overturning Circulation — a key ocean current that regulates global weather.

Researchers say current policies are unprepared for such abrupt and interconnected changes. They urge rapid cuts in planet-heating emissions and large-scale carbon removal.

Despite the grim outlook, the report highlights progress in solar energy, electric vehicles, and clean technologies.

“This must be a wake-up call,” said WWF’s Mike Barrett. “Without decisive action, we risk losing the Amazon, ice sheets, and vital ocean currents — with catastrophic consequences for humanity.”
