Comfortable living space a significant aspect that policymakers need to address sustainable planning. There still notable lack studies link spatial profile climate with city-specific built-up settings while assessing vulnerability city population. Geospatial approaches can be beneficial in evaluating patterns thermal discomfort and strategizing its mitigation. This study attempts provide thorough remote sensing framework analyze summer magnitude tropical hot humid climate. Spatial profiles dry bulb temperature, wet temperature relative humidity were prepared this purpose.

The frequency and intensity of extreme thermal stress conditions during summer are expected to increase due climate change. This study examines sixteen models from the Coupled Model Intercomparison Project Phase 6 (CMIP6) that have been bias-adjusted using quantile delta mapping method. These provide Universal Thermal Climate Index (UTCI) for seasons between 1979 2010, which regridded a similar spatial grid as ERA5-HEAT (available at 0.25° × resolution) bilinear interpolation. evaluation compares summertime climatology trends CMIP6 multi-model ensemble (MME) mean UTCI with ERA5 data, focusing on regional hotspot in northwest India (NWI). Pattern Correlation Coefficient (between ERA5) values exceeding 0.9 were employed derive MME UTCI, was subsequently used analyze models.The climatological demonstrates significant over NWI region, ERA5. Both show rising trend NWI. temporal variation analysis reveals experiences higher compared rest India. number days is also increasing major Indian cities according MME. Future projections under different scenarios (SSP1-2.6, SSP2-4.5, SSP5-8.5) indicate an discomfort throughout twenty-first century. projected rates approximately 0.09 °C per decade, 0.26 0.56 respectively. Assessing near (2022-2059) far (2060-2100) future, all three suggest rise intense heat (UTCI > 38 °C) Notably, predict could reach deadly levels high-emission (SSP5-8.5) scenario. findings underscore urgency addressing change its potential impacts human well-being socio-economic sectors.

Extreme heat-precipitation events, such as heatwaves and extreme precipitation, can have substantial impacts on the population, particularly in urbanized watersheds. However, few studies investigated individual compound causing much valuable information loss for watershed climate risk management. This study focuses Pearl River Basin (PRB), a highly area southern China, aims to predict changes population exposure events. To achieve this, ranked ensemble global model (GCM) was used generate projections heatwaves, sequential coincident heat waves precipitation extremes (SHWPs CHWPs) under three future scenarios (SSP-RCPs). The main findings of are follows: Precipitation represent increasing days intensity all across PRB. Towards end 21st century, SSP5-8.5 scenario predicts that will last ten times longer than historical records. Comparing two types we conclude century see near-term high SHWPs long-term CHWPs Furthermore, both five hotspot cities PRB (i.e., Guangzhou, Dongguan, Foshan, Shenzhen, Huizhou) face higher These share common characteristics: key economic development, coastal, densely populated. provide insight into management other tropical subtropical basins.

Global warming is a pressing problem that necessitates immediate action. This phenomenon particularly affecting the quality of life in larger cities due to population growth and human mobility. Understanding space-time variability heat stress various locations will face future therefore crucial for us. Taking into account aforementioned facts, current study examined evolution Hi index four European capitals - Berlin, Madrid, Paris, Rome during months July, August, September between 2008, 2012, 2017. The Space Agency (ESA) UrbClim climate model was used collect environmental data. Furthermore, Local Climatic Zones (LCZ) classifications land use/cover change (LULC) coverages were improve evaluation extrapolation results. According findings, studied areas experienced significant increases temperatures 2008 cities' average increase 0.31 °C per decade, with southern experiencing greater intensity northern less intensity. When comparing spatiotemporal different zones, discovered more impervious fewer green are vulnerable potential stress. As result, urban developments can be able create spaces resistant stress, improving people's life.

Abstract Climate change is closely monitored and numerous studies reports increasing air temperature weather extremes across the globe. As a direct consequence of increase global temperature, increased heat stress becoming threat to public health. While most climate epidemiological focus on explain risks, strain can be predicted using comprehensive indices such as Universal Thermal Index (UTCI). The Asia–Pacific region prone thermal high population densities in impose health risk. This study evaluated UTCI trends between 1990 2019 found significant for whole while increases are not pronounced mainly northern part region. These results indicate that even though increasing, risks when assessed may alleviated by other factors. associations El Niño Southern Oscillation (ENSO) was seasonal level strongest regional responses were during December-January (DJF) March–May (MAM).

Abstract Severe weather events, such as heat waves, floods, pollution, and health threats, are becoming more common in metropolitan places across the world. Overcrowding, poor infrastructure, fast, unsustainable urbanization some of problems that India faces, country is also susceptible to natural disasters. This research analyzes climatic variables affecting urban hazards Bangalore (also known Bengaluru) via a thorough review. Heat islands, drought were identified 156 qualifying publications using Preferred Reporting Items for Systematic Reviews Meta-Analysis (PRISMA) method. Contributing considered. City development key changing climate increasing dangers. While long-term variable distribution uneven, warming evident. The report promotes strong planning techniques, comprehensive policies, green areas, sustainable beyond short-term response programs boost resilience. study shows how climate, land use, dangers interconnected. Future studies may benefit by categorizing risk identifying factors.
