Abstract Central Asia (CA) is a critical agricultural region, contributing significantly to global food and cotton production, yet it faces increasing threats from extreme heatwaves (HWs) due warming. Despite this, the specific impacts of historical future HWs on CA's cropland remain underexplored. Here, using five bias‐corrected circulation models Inter‐Sectoral Impact Model Intercomparison Project Phase 3b (ISIMIP3b), we present detailed analysis exposure periods (1995–2014) under three Shared Socioeconomic Pathways (SSP126, SSP370, SSP585) for 2021–2100. Compared levels, find that heatwave frequency could increase by 199% 2081–2100 SSP126, while duration rise as much 852% 1143% SSP370 SSP585, respectively. Northern Kazakhstan emerges particularly vulnerable, with highest levels across scenarios. Interactive effects between climate shifts land‐use changes are dominant contributors, accounting over 50% total in each scenario. These findings highlight vulnerability various pathways, emphasizing urgency targeted adaptation strategies protect regional resilience and, extension, security.

Abstract Background and aims Coastal dunes provide vital ecosystem services, including flood protection freshwater storage. These ecosystems are shaped by clonally-growing dune grasses that trap sediment as patch size increases, enabling the to avoid stress from seawater flooding scarcity. However, it remains poorly understood how increasing climate extremes will impact establishment survival dynamics of this vegetation. This study investigated effects an experimental climatic compound drought heatwave (CDHW) on Elytrigia juncea in embryonic field. Methods Over a four-week field experiment, we examined two plant-patch sizes (0.014 m 2 vs. 1.953 ) treatments (ambient CDHW), monitoring plant response soil moisture. We hypothesized larger patches would better resist CDHW due their enhanced storage within bodies. Results Contrary our expectations, E. exhibited positive CDHW, with longer shoots both sizes. Initial moisture profiles remained similar across throughout experiment. Moreover, indicated substantial source reach roots all plots, explaining absence stress. Conclusion Our findings suggest pioneer can be highly resistant when fresh groundwater, condition which occur thin lens is present proximity complexes. For establishing grasses, not merely formation local scale but rather landscape crucial for coping extreme events.

ABSTRACT In September 2024, the Yangtze River basin experienced a supremely extreme heatwave that broke historical records from at least 1961 and could have severe impact on outdoor health of school children. This paper provides timely analysis characteristics in its exposure to population aged 14 years below, causes led occurrence, as well future projections. regional average days reached 7.57 days, daily maximum temperature ( T max ) 31.53°C, both which are much higher than climatology exceed records. resulted high under, with provinces Sichuan, Chongqing, Hunan, Jiangxi exposed more 100 million person‐days. The expansion South Asian High (SAH) Western Pacific Subtropical (WPSH) may directly contributed this heatwave. CMIP6 projections show frequency heatwaves similar 2024 will increase future.

Extreme climate events have become more frequent under global warming, significantly affecting vegetation phenology and carbon cycles in Central Asia. However, the mediating effects of intensity compound drought heat (CDHEs) moisture (CMHEs) on grassland their trends relative contributions to over time remained unclear.

Global warming has exacerbated the impact of regional drought on vegetation ecosystems, especially in typical karst areas with fragile ecosystems that are more severely affected by drought. However, response mechanisms to stress still uncertain. With summer 2022, we examined spatiotemporal patterns a World Heritage site, Guilin, China, and revealed impacts various indices. Firstly, analyzed characteristics from 2000 utilizing temperature dryness index (TVDI), highlighting intra-annual variability 2022. Additionally, compared responses different types non-karst explored within same year three indices, namely, Normalized Difference Vegetation Index (NDVI), Leaf Area (LAI), Gross Primary Production (GPP) areas. The results showed started July persisted August November at moderate severe levels (with September), eventually easing December.
