The West Antarctic Ice Sheet could reach its tipping point with only minimal additional ocean warming – with long-term consequences for global sea levels. But a small window of time remains to take countermeasures.

Les lois de puissance s’appliquent aussi aux catastrophes climatiques. L’économie classique du climat et les modèles utilisés sont inadaptés. Les approches robustes permettent de combiner prudence pour éviter la catastrophe, et raisonnement économique.

Delegates made minimal headway on timetable for replacing oil and gas or on firm commitments to reducing carbon emissions

It looked like snow under water: white, endless, and still. The reef, my friend Lisbeth said, was “the most beautiful thing she’d ever seen.” For a second, I almost agreed. Then, I stared at it for a long time before replying. She wasn’t wrong about its beauty. But she was also showing me death. Bleached coral isn’t a kind of coral. It’s the moment just after the funeral, what’s left when life is gone. A cathedral of bone-white skeletons stretching over an empire of calcified death. From above, it glows like marble. Up close, it’s a graveyard.

Les récifs coralliens ont franchi un "point de basculement" climatique

Unless global heating is reduced to 1.2C ‘as fast as possible’, warm water coral reefs will not remain ‘at any meaningful scale’, a report by 160 scientists from 23 countries warns

GLOBAL TIPPING POINTS REPORT - 2025

GLOBAL TIPPING POINTS REPORT 2025 - Summary

L’humanité a trop déstabilisé le climat, au point de l’avoir rapproché de « points de bascule » au potentiel cataclysmique, alertent 160 scientifiques dans un nouveau rapport.

If atmospheric CO2 levels exceed 1,200 parts per million (ppm), it could push the Earth’s climate over a “tipping point”, finds a new study. This would see clouds that shade large part of the oceans start to break up.
