Short Summary

This study investigates how precipitation variability responds to symmetric carbon dioxide removal experiments using CMIP6 models, revealing an asymmetric response across time scales.

Objective

• Investigate the impact of CO2 forcing on precipitation variability at various temporal scales

Study Configuration

• Spatial Scale: Global and regional (North America, Europe, South Asia, East Asia)
• Temporal Scale: Day-to-day to intraseasonal (time scales from days to weeks)

Methodology and Data

• Models used: CMIP6 models (idealized carbon dioxide removal experiments)
• Data sources: Model output data

Main Results

• Precipitation variability strengthens with increasing CO2 concentrations.
• The ramp-down phase shows stronger precipitation variability than the ramp-up phase, even at comparable CO2 concentrations.
• Asymmetry is evident across time scales and pronounced over densely populated regions.

Contributions

• This study highlights a previously unknown asymmetric response of short-timescale precipitation variability to CO2 forcing, contributing to the understanding of hydroclimatic variability beyond CO2 reduction periods.
