Under climate change, China faces intensifying compound extreme events with serious socio-economic ramifications, yet their future variations remain poorly understood. Here, we estimate historical hotspots and changes of two typical events, i.e., sequential heatwave precipitation (SHP) concurrent drought (CDH) across China, leveraging a bivariate bias correction method to adjust projections from global models. Results show substantial increases in frequency, duration, magnitude for both the durations projected double nationwide. The are more evident under higher emission scenarios, could be largely underestimated if neglecting variable dependence during process. will escalate exposure China's major urban clusters, among which Guangdong-Hong Kong-Macao face highest risk. Our findings underscore necessity carbon controls, call adaptive measures mitigate threats induced by rising hazards changing climate.
