Higher warming leads to a larger zero-emissions commitment
Nature · By June-Yi Lee ·
The Brief
- A Nature Climate Change study published online on 10 November 2026 examines committed warming after CO2 emissions cease.
- Scientific grounds for net-zero policy assume near-zero committed warming over a few decades after emissions stop.
- A modelling study suggests that if prior peak temperatures rise, the zero-emissions commitment grows larger.
Why it matters
If committed warming after emissions stop is larger at higher peak temperatures, the near-zero assumption behind net-zero policy may need revisiting.
