# Planetary boundaries transgression status > Live situation record from CLSTR: https://clstr.news/situations/planetary-boundaries-transgression-status > Updated: 2026-09-23T16:12:22.000Z. Sources: 23. Developments: 2. The 2026 Planetary Health Check, a report produced by the Potsdam Institute for Climate Impact Research (PIK) and the Planetary Guardians, indicates that seven of the nine critical planetary boundaries essential for human stability have been exceeded. These transgressions have reached their highest levels to date, increasing the risk of irreversible changes to the Earth system. The breached boundaries include climate change, biosphere integrity, land-use change, freshwater systems, biogeochemical cycles, the introduction of novel entities, and ocean acidification. Ocean acidification is noted as the most recent threshold to be crossed, occurring in 2025. While the report warns that the planet’s natural resilience is weakening and tipping points may be emerging, it notes that stratospheric ozone depletion and atmospheric aerosol concentrations are the only two indicators that have shown improvement over the last decade. Researchers assert that humanity retains the capacity to return to a safe operating space if immediate action is taken. ## Timeline ### 2026-09-23: Planetary Health Check reports seven of nine Earth boundaries exceeded The 2026 Planetary Health Check reveals that seven of nine critical planetary boundaries have been exceeded, reaching record levels of violation and threatening Earth's stability. 2 sources. https://clstr.news/cluster/planetary-health-check-reports-seven-of-nine-earth-boundaries-exceeded ### 2026-09-21: Planetary boundaries: Seven of nine Earth limits exceeded The 2026 Planetary Health Check report reveals that seven of nine planetary boundaries have been exceeded, reaching record levels of transgression and threatening global stability. 21 sources. https://clstr.news/cluster/planetary-health-check-seven-of-nine-earth-boundaries-exceeded --- Cite as: Planetary boundaries transgression status.
