Global warming is emerging as an important predictor of water availability and future supplies across the world through inducing frequency severity in hydrological extremes. These extremes (e.g., drought) have potential impacts on groundwater, environmental flows, well increase social inequalities (limited access to by poor), among a range other issues. Understanding influence global climate groundwater systems thus critical help reshape markets policies underpinned knowledge climatic processes driving cycle freshwater supply. The main aim this study improve understanding variability using statistical methods multi-linear regression wavelet analyses). response are assessed feasibility identifying hotspots groundwater-climate interactions explored (2003-2017).

This attuned local needs evaluation, tests applicability Guide Safety Resilient City Evaluation (GB/T 40947–2021) study. Moreover, it incorporates key common extracted from prior studies on evaluation. Zhejiang Province, flood-prone area China, selected as study area, their trends 2011 2020. results show that improved economic, infrastructure aspects, while social aspect remain high.

This study examines the effect of land cover, vegetation health, climatic forcings, elevation heat loads, and terrain characteristics (LVCET) on surface temperature (LST) distribution in West Africa (WA). We employ fourteen machine-learning models, which preserve nonlinear relationships, to downscale LST other predictands while preserving geographical variability WA. Our results showed that random forest model performs best downscaling predictands. is important for sub-region since it has limited access mainframes power multiplex algorithms. In contrast northern regions, southern regions consistently exhibit healthy vegetation. Also, areas with unhealthy coincide hot clusters. The positive Normalized Difference Vegetation Index (NDVI) trends Sahel underscore rainfall recovery subsequent Sahelian greening. southwesterly winds cause upwelling cold waters, lowering WA highlighting cooling influence water bodies LST. Identifying elevated paramount prioritizing greening initiatives, our underscores importance considering LVCET factors urban planning. Topographic slope-facing angles, diurnal anisotropic all contribute variations LST, emphasizing need a holistic approach when designing resilient sustainable landscapes.

Abstract Understanding how droughts are characterized, propagated, and projected, particularly multivariate droughts, is necessary to explain the variability changes in drought characteristics. This study aims understand multimodel global monitoring, propagation, projection by utilizing a standardized index (MSDI) during historical (1959–2014) future (2045–2100) periods under two socioeconomic pathways SSPs (370 585), derived from bias‐corrected Coupled Model Intercomparison Project Phase 6 (CMIP6). Based on energy metrics, bias correction method outperformed other techniques correcting biases CMIP6 representation. The indicators demonstrate distinct categories for meteorological, hydrological, droughts. There were significant high cross correlations between Heatwave Total Length (HWTL) MSDI Africa South America all lagged times. Europe North generally saw maximum duration (228 months) period. For projections, recorded (197 months), while witnessed minimum SSP 370 (171 (149 585. Furthermore, period tropical Africa, propagation of meteorological hydrological was slower wet months than dry months. Under projection, there shift long meteorological‐hydrological middle late beginning Africa. Therefore, tracking projecting characteristics vital understanding risk drought‐related consequences.

Global water scarcity threatens agriculture, food security, and human sustainability. Hence, understanding changes in terrestrial storage (WS) is crucial. By utilizing climate models, reanalysis, satellite data, we demonstrate the effectiveness of multivariate bias correction technique facilitating precise WS representation while ensuring robust budget closure. Historical data indicate seasonal changes, where forested basins exhibit a surplus December-January-February season, with reversal June-July-August-September season. Non-forested display varied patterns influenced by geographical location land use type. Future projections increased deficits most Southern Hemisphere under middle-road (SSP 245) scenario wetter conditions regional rivalry 370) scenario. Weather systems governing vary season basin, resulting inconsistent moisture intake into basins. These findings underscore intricate interplay between transport, characteristics, WS, highlighting need to understand these complex interactions for effective resource management strategies changing climates.

This study investigates the potential future state of a coastal karst aquifer located in Salento peninsula southern Italy, examining impact climate change. After historical and overview area, an analysis meteorological indices (SPIs SPEIs) groundwater levels (GWLs) during period revealed strong correlation between them. Then, straightforward linear regression models were applied to establish relationships SPIs/SPEIs GWLs for analysed wells. To estimate SPIs SPEIs, ensemble regional was used, estimates until end century obtained by incorporating these projections into models. Two emission pathways, RCP4.5 RCP8.5, considered analysis. The results based on suggest no significant changes across all However, when considering also temperature through use general decline is expected, with decrease being more pronounced under RCP8.5.

Compound extreme events, encompassing drought, vegetation stress, wildfire severity, and heatwave intensity (CDVWHS), pose significant threats to societal, environmental, health systems. Understanding the intricate relationships governing CDVWHS evolution their interaction with climate teleconnections is crucial for effective adaptation strategies. This study leverages remote sensing, reanalysis data, models analyze during historical (1982–2014), near-future (2028–2060), far-future (2068–2100) periods under two Shared Socioeconomic Pathways (SSP; 245 585). Our results show that reduced health, unfavorable temperature conditions, low moisture conditions have negligible effects on density. However, they worsen of heatwaves increase risk wildfires. Wildfires can persist when thermal are poor despite favorable levels. For example, adequate availability, we link 2012 Siberian in Ob basin anomalous negative concurrent thermal-moisture conditions. In contrast, Amazon experiences exceptional drought associated same year. A comparative analysis North American fires reveals distinct burned area anomalies due variations density fuel. The lower positive areas because density, which amount Furthermore, examine basin-specific variability related compound CDVWHS, revealing primary modes through teleconnection patterns. Moreover, a substantial magnitude severity emerges between near far future SSP 585. underscores urgency targeted actions enhance ecosystem resilience safeguard vulnerable communities from impacts.

Surface coal mining in semi-arid regions has detrimental impacts on the structure and function of surface ecosystems, thereby impeding attainment regional sustainable development goals. Moreover, impact climate change ecological restoration areas is an inevitable consideration. To elucidate response ecosystem services to change, topography, soil, vegetation socioeconomic development, this study selected six large-scale mines located China as research objects. In study, we aimed assess main (carbon sequestration, soil conservation, flow regulation) provided by these mines. addition, analysed spatial temporal evolution interrelationships services. Furthermore, explored underlying mechanisms between environmental factors. The results showed following: (1) Geospatially, there was a gradual decrease carbon sequestration regulation from northeast southwest areas. However, conservation exhibited upward trend. Throughout period, rate displayed initial downward subsequent trend, decline followed (2) Change significant positive correlation (r = 0.51, p < 0.001), with strongest observed Shengli Mining Area 0.64, 0.001). (3) Ecosystem service changes were primarily driven conditions (95.0%), meteorological factors (4.2%).
