Executive editor
As a core contribution to CMIP7, this paper offers an idealized yet insightful projection of climate system behavior during the net-zero transition. Its policy relevance is clear, as it effectively links human-driven emission mitigation efforts with their climatic consequences.
Short summary
This study investigates how climate models warm in response to simplified carbon emissions trajectories, refining the understanding of climate reversibility and commitment. Metrics are defined for warming response to cumulative emissions and for the cessation of emissions or ramp-down to net-zero and net-negative levels. Results indicate that previous concentration-driven experiments may have overstated the Zero Emissions Commitment due to emissions rates exceeding historical levels.
