Abstract The increasing frequency and intensity of extreme precipitation events pose growing societal risks, underscoring the urgent need for effective early warning systems. Forecasting such events at subseasonal-to-seasonal timescales, however, remains a major scientific challenge.

Abstract Large-scale concurrences of humid heatwaves substantially escalate the risks of heat-related mortality. However, quantifying the origins of these concurrent extremes remains challenging. Here we use a complex network approach applied to climate reanalysis data to show that the observed intensification of humid heatwaves is closely associated with coastal oceanic warming over the period 1982–2023.

Abstract Heatwaves are projected to substantially increase at a global scale, exacerbating worldwide heat-related risks in the future. However, understanding future heterogeneous heatwave changes and their origins remains challenging.
