Short Summary

This study investigates the response of compound climate extremes to carbon dioxide removal (CDR) pathways using a CO 2 ramp-up and ramp-down experiment with CESM1. The results show that CDR does not lead to complete recovery of global mean temperature, precipitation, and wind speed by 2300.

Objective

• Investigate changes in compound climate extremes under different CDR scenarios

Study Configuration

• Spatial Scale: Global scale, with a focus on regional changes
• Temporal Scale: Long-term experiment (up to 2300) with a ramp-up and ramp-down phase

Methodology and Data

• Models used: CESM1 with 28 ensemble members
• Data sources: Not specified in the abstract

Main Results

• Incomplete recovery of global mean temperature, precipitation, and wind speed by 2300
• Changes in frequencies of compound climate extremes (CDNHE, CDHE, CPWE)
• Regional increases in CEs can exceed those of individual components by 20–35 percentage points

Contributions

• Provides new insights into the response of compound climate hazards to CDR pathways
• Highlights the importance of accounting for delayed recovery when evaluating CO 2 removal strategies

Funding

• Not specified in the abstract
