What happened
The 2025 Global Tipping Points report reveals that five vital Earth systems are approaching irreversible change, with one system already likely past its tipping point. This assessment, updated from a 2023 report, highlights the precarious state of coral reefs, tropical forests, and polar ice sheets, all of which are crucial for maintaining global biodiversity and climate stability. Coral reefs have already experienced significant bleaching, while the Amazon rainforest is at risk of collapse due to both climate change and deforestation. The report warns that unchecked climate change could lead to mass mortality, forced displacement, and severe economic losses worldwide. However, it also suggests that proactive measures, such as reducing deforestation and protecting marine ecosystems, could help delay or prevent these tipping points.
