2022年のパキスタン洪水と長江流域の熱波の同時発生について、人為的気候変動の寄与を確率的・ストーリーライン手法で定量化。人為的強制がイベント発生確率のほぼ100％を説明し、今世紀末には発生確率が57～326倍に上昇すると予測。
English
This study quantifies anthropogenic contribution to the 2022 concurrent Pakistan flood and Yangtze heatwave using probabilistic and storyline attribution. Anthropogenic forcing accounts for nearly 100% of event likelihood; projections show 57–326× increase by 2071–2100 relative to historical baseline.

📄 Abstract（原文）
During July–August 2022, Pakistan (PKT) experienced catastrophic flooding while the Yangtze River Basin (YRB) endured unprecedented heatwaves. While previous studies have examined the physical teleconnections, there remains a critical gap in quantifying the role of anthropogenic forcing in shaping such trans‐regional concurrent extremes. Here, we bridge this gap by combining probabilistic and storyline attribution frameworks to assess both historical and future risks of 2022‐like events. We find that the 2022 event represents a warming‐amplified analogue of the 2010 event, driven by a westward extension of the Western Pacific Subtropical High (WPSH) and an eastward shift of the South Asian High (SAH). Moisture and heat budget diagnosis reveal that dynamically horizontal moisture transport dominated the 2022 PKT precipitation, while surface cloud‐radiative forcing drove the YRB heatwave. Using complex network analysis, we uncover intensified cross‐regional linkages under SSP2‐4.5, SSP3‐7.0, and SSP5‐8.5 scenarios. Crucially, our bivariate probabilistic attribution indicates that anthropogenic forcing accounts for nearly 100% of the likelihood of the 2022 event. Projections show that, by 2071–2100, the probability of such events could rise by 57–326 times, relative to a baseline probability of 0.0015 in historical simulations. Further, storyline attribution demonstrates that anthropogenic thermodynamics and circulation dynamics contributed approximately 60% and 40% to the 2022 event, with nearly half of the dynamic effect attributable to anthropogenic forcing. These results offer a quantitative perspective on the rising risk of concurrent Pluvial Pakistan–Hot Yangtze events under climate change, offering valuable insights for regional climate resilience and adaptation planning.
