Based on the condition of limiting the rise in global average temperature to within 1.5°C, the analysis showed that Earth's safe limit for annual CO₂ emissions is approximately 4–17 gigatons (Gt CO₂ per year). However, humanity's current annual emissions amount to about 37 gigatons (Gt CO₂ per year). This level exceeds Earth's safe operating space by more than twofold.https://phys.org/news/2026-03-carbon-emissions-planetary-boundary-analysis.html#Climate #BurnItDown #DeathByPetro
