Global Tipping Points Report 2025

The latest Global Tipping Points Report 2025 warns that Earth’s climate and ecosystems are already approaching dangerous thresholds. With global warming at ~1.4°C, warm-water coral reefs are “crossing their thermal tipping point” and suffering unprecedented die-offs, jeopardizing the livelihoods of hundreds of millions who depend on them. The report cautions that even stabilizing at 1.5°C warming makes a near-total global reef collapse virtually certain, absent a return to cooler conditions. However, it calls for urgent action to minimize overshoot of 1.5°C and trigger positive tipping points – self-perpetuating shifts like rapid adoption of clean energy – as the only credible path to avert further catastrophic tipping events. Leaders heading into COP30 are urged to act immediately to reduce emissions and protect remaining resilience in systems like coral reefs, emphasizing that every fraction of a degree matters in tipping the future towards sustainability (Source: Global Tipping Points, 2025).
