Planetary boundaries are scientific guardrails for pressures on Earth’s interconnected systems. Crossing them raises environmental risks; it does not mean a system has stopped working or establish a date for collapse.

7 of 92026 assessment · published 21 September 2026 · Global · observation years vary
The report finds rising pressure across all seven exceeded boundaries. Ocean acidification was first assessed as exceeded in 2025. This is an assessment, not a live counter.
PIK — Planetary Health Check 2026, published 21 September ↗ How to read this section
Ozone depletion and aerosol loading remain within the framework’s global boundaries. Regional aerosol pollution can still be unsafe.
The nine categories interact and differ in severity. Counting them is not a percentage of Earth destroyed or a probability of collapse.
Context only: this assessment adds no points or penalties to Civometer’s long-term or daily score. The daily-v1 method has no planetary-boundary term; adding one would require a documented methodology change.
Publication and review dates are separate from observation years. This targeted addition does not mean every Nature source was rechecked.
