In recent years, compound extreme events have occurred with increasing frequency worldwide. A specific type of compound extreme event, drought‐flood abrupt alternation (DFAA), has been reported repeatedly, especially in China. Previous studies have revealed that DFAA events mainly occur in south‐eastern China. As the third largest watershed in the world, the Yangtze River Basin (YRB) is of strategic importance for China's socio‐economic development. DFAA events typically have negative impacts on agricultural production, the ecological environment, and other sectors. Therefore, this study investigates the evolutionary patterns of DFAA events in the YRB, aiming to quantitatively assess the impacts of climate change on one of China's major grain‐producing regions. The results indicate that the occurrence of DFAA events has increased over the past 6 decades, with the highest annual frequency rising from 3.5 to 7 times per year. Moreover, the average annual area proportion affected by DFAA events exhibits a statistically significant increasing trend ( p < 0.05) of 0.646% per decade. The intensity of DFAA events was also evaluated. These findings can inform targeted regulation of DFAA events in the YRB.

Extreme snowfall events have frequently occurred across parts of Eurasia, causing substantial economic losses and severe societal impacts. As global warming intensifies, assessing its potential effect on population exposure to such extremes becomes increasingly crucial. This study employed CMIP6 model datasets and future population projections to predict changes in population exposure to snowfall extremes over Eurasia under SSP2‐4.5 and SSP5‐8.5 scenarios, and attributed the drivers behind these changes. Results indicate that, on average across Eurasia, both extreme snowfall days and the associated population exposure increase until the mid‐21st century (2041–2060). Specifically, population exposure to snowstorm days will increase by 4.1% in the near term (2021–2040) and by 1.8% in the medium term, with particularly pronounced increases over Central Asia, East Asia, and the Mediterranean. Population change is identified as the dominant factor influencing exposure changes across Eurasia, followed by climate change and climate‐population synergistic effects. Toward the end of the century, as both snowstorm days and population size decline markedly, the corresponding population exposure decreases further. Thus, climate adaptation policies should account for the heightened population risks linked to increasing snowfall extremes in Eurasia up to the mid‐21st century.
