What does this research mean for the field?

Future increases in the frequency and intensity of extreme precipitation in the Yangtze River Basin will substantially amplify socioeconomic exposure, with population exposure driven primarily by climate effects and GDP exposure driven by a combination of climate change and economic growth. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To project future shifts in extreme precipitation and quantify the resulting exposure risks for human populations and regional economic output.

Climate modeling analysis reveals intensifying extreme precipitation across future scenarios, indicating substantial increases in population and economic exposure.

Key Points

To project future shifts in extreme precipitation and quantify the resulting exposure risks for human populations and regional economic output.
Evaluated high-resolution NEX-GDDP-CMIP6 climate model simulations against CN05.1 observational data using Taylor diagrams, Taylor Skill Scores, and Interannual Variability Scores.
Applied Extreme Value Theory with Generalized Extreme Value distributions to calculate 10-year and 20-year return levels for RX1day and RX5day extreme rainfall indices.
Conducted contribution analyses across future climate scenarios combined with population and GDP projection datasets.
The multi-model ensemble mean reliably captured observed spatial and temporal patterns of extreme precipitation, consistently outperforming individual models.
Basin-wide mean values across all eight extreme precipitation indices displayed significant upward trends, reflecting increased frequency and intensity of extreme events.
Socioeconomic exposure rose substantially through the 21st century, with population exposure driven predominantly by climate factors and GDP exposure driven jointly by climate change and economic expansion.
