The Global Tipping Points Report 2025 warns that the world is nearing multiple catastrophic climate tipping points as global warming surpasses 1.5°C. These include coral reef dieback, melting polar ice sheets, potential collapse of the Atlantic circulation system, and Amazon rainforest degradation—all threatening billions of lives, biodiversity, and global stability.
The report stresses that every fraction of additional warming heightens these risks, which are interconnected and mutually reinforcing. To avoid irreversible damage, emissions must be halved by 2030 and reach net zero by 2050 through rapid decarbonization, methane reduction, and large-scale carbon removal. While current national commitments fall short, the report highlights hope in “positive tipping points”—self-reinforcing shifts in technologies and behaviors such as the rapid adoption of solar power, electric vehicles, and climate litigation. It calls for decisive policy action and mass civil society mobilization, like the Global Mutirão, to trigger cascading positive change and avert climate collapse.
