Heatwaves are increasingly frequent and severe, prompting international research concerns. This study utilized the Visibility Graph to construct complex networks (CNs) of heatwaves in China. From a CN perspective, we analyzed spatial temporal variability hazard patterns heatwaves, with focus on their reliability advantages. Our findings indicate that China have exhibited consistent overall increasing trend since 1961, more significant rise observed past 30 years. Notably, there substantial variations changes severity experienced different regions decades, southern experiencing higher hazards compared central where they relatively lower. The utilization CNs has demonstrated remarkable advantages anomaly detection, change phase delineation, analysis connections between meteorological stations, selection representative values.

Climate change is exacerbating the occurrence of compound droughts and heatwaves (CDHWs), which pose a serious threat to human health socio-economic development. Using daily maximum temperature (Tmax) monthly self-calibrating Palmer drought severity index (sc-PDSI) dataset, The evolution patterns CDHWs wet-heatwave events, dominant drivers relative contributions in drylands humid areas from 1961 2020 were compared analyzed. results show that types are stronger than areas, growth rate was almost twice greater multi-year average intensity events by up 2.4 times. Moreover, has increased significantly past period (1961–1990) recent warm (1991–2020), heatwave threshold about 5 °C. In most drylands, contribution dominates, whereas does. compounding effects may exacerbate regionally pronounced taking into account optimal lags. study findings could provide scientific technological support actively address global climate risks.

More frequent and intense heatwave events (HWEs) on the Tibetan Plateau (TP) present substantial threats to ecological hydrological systems. However, understanding changes in HWEs TP is limited, primarily from analyses at individual stations or single elements (glaciers, lakes). Here, using refined data, we quantify magnitude by aggregating multiple indicators into a comprehensive index explore influence of environmental factors over TP. Our findings indicate that has significantly increased since 21st century, especially autumn. From 1979–2000 2001–2022, hotspots migrated toward northwestern TP, whereas regions with most rapid increase shifted opposite direction. During inter-seasonal, spring winter, migration direction changed northwest first 22 years (1979–2000) southeast recent (2001–2022). We also find downward shortwave radiation plays significant role spatial stratified heterogeneity (SSH) magnitude, while trend temperature dominant SSH magnitude. Moreover, elevation correlated variability. The elevation-dependence become more pronounced years, high-heatwave migrating higher elevations. Furthermore, difference land cover type can affect intensity some extent. underscore patterns evolution around century provide scientific basis for interaction between different periods.

Heatwave exposure has increased dramatically because of climate warming and population growth, along with their interactive effects. However, effective adaptation measures can reduce these impacts. Nonetheless, the dynamic changes, regional inequality in adaptive capacity potential contributions to reducing future remain unclear. This study quantifies impact underscores variations heatwave magnitudes, levels China. We projected using air-conditioner penetration, factoring cooling requirements individuals' purchasing power. Utilising gross domestic product (GDP) data from four Shared Socioeconomic Pathways (SSP1, SSP2, SSP3 SSP5) daily temperature SSP-based emission scenarios (SSP1-2.6, SSP2-4.5, SSP3-7.0 SSP5-8.5), we estimated duration, avoided impacts through across China its sub-regions. Results show a substantial increase duration Southwest Southern China, especially under SSP5-8.5 scenario, projection 163.2 ± 36.7 d during 2081–2100. Under SSP3|SSP3-7.0 total reaches 156.4 76.8 billion person per year, which is highest among all 23 times greater than that 1986–2005 without adaptation.

Abstract In the context of global warming, frequency, intensity, and duration heatwave events have markedly increased, bearing profound implications for both natural ecosystems human societies. To effectively cope with this challenge, it is imperative to accurately identify comprehensively assess risks posed by heatwaves. This study undertakes a systematic approach robust methodology leveraging diverse array data sources—encompassing remote sensing, statistical analyses. The integrates risk triangle theory alongside established assessment frameworks laid out Intergovernmental Panel on Climate Change (IPCC). Employing three‐dimensional evaluation framework encompassing hazard, exposure, vulnerability, we unravel spatial–temporal patterns, high‐risk zones, dominant dimensions contributing potential disasters. Results indicated that during 1999–2008, roughly 27% areas were affected high above levels heatwaves, very vulnerability accounted approximately 19.5%, 10%, 32.5%, respectively. During 2009–2018, proportion risk, exposure increased about 31%, 26%, 14%, respectively, while percentage decreased 24.43%. Notably, Xinjiang western part Northwestern China are characterized hazard‐dominant conditions, Southern China's profile has shifted from 1999–2008 2009–2018 hazard conditions more complex interaction involving vulnerability. Moreover, Northern northern segment Southwestern exhibit simultaneous rankings across dimensions, forming comprehensive zone. These findings characterize patterns offer critical insights management decisions, guiding effective disaster prevention relief measures ensure socio‐economic stability public health.
