Earth beyond six of nine planetary boundaries

📅 September 13, 2023 👤 Katherine Richardson, Will Steffen, Wolfgang Lucht et al. 📖 Science Advances 📊 2,789 citations

🤖 Plain-English Summary

This planetary boundaries framework update finds that six of the nine boundaries are transgressed, suggesting that Earth is now well outside of the safe operating space for humanity. This boundary is also transgressed.

🔑 Key Findings

  • Ocean acidification is close to being breached, while aerosol loading regionally exceeds the boundary.
  • Stratospheric ozone levels have slightly recovered.
  • The transgression level has increased for all boundaries earlier identified as overstepped.

💡 Why This Matters

Mathematical breakthroughs form the theoretical backbone of science, cryptography, data analysis, and engineering.
