Climate change and the quest for 'positive tipping points'
When world leaders gather in Belém, Brazil this November for the 2025 UN Climate Change Conference (COP30), they will need to confront an uncomfortable truth: the planet is running out of time. The era of climate diplomacy built on promises is over; the age of implementation must begin.
A stark reminder of this urgency came from the Global Tipping Points Report 2025, authored by 160 scientists from 87 institutions across 23 countries. Its findings are chilling: Earth has already crossed its first major climate tipping point. Warm-water coral reefs, the once vibrant ecosystems that sustained a quarter of marine life, are dying on a massive scale. This coral reef devastation marks the start of irreversible environmental shifts.
Without immediate and coordinated global action to limit warming to 1.5°C, the planet risks cascading crises, ranging from collapsing ice sheets, to rising seas, drying rivers and dying forests. The only way forward is through rapid and widespread adoption of clean technologies that can trigger "positive tipping points".
