Urban green spaces (UGSs) are crucial for mitigating land surface temperature (LST) in the context of climate change and extremely high temperatures. Although numerous studies have explored impact UGSs on LST, a systematic understanding research scope, knowledge network structure, data sources, main methods, frontier trends this field is lacking. In study, 740 documents were retrieved from Web Science database, hotspots, trends, frontiers LST analyzed using scientometric analysis CiteSpace 6.2.R4 software. The results revealed that annual number publications citations has increased consistently, with rapid growth 2019 to 2024. However, communication dissemination findings hindered by lack efficient international collaboration networks academic institutions authors, highlighting need more vigorous global exchanges cooperation. Additionally, eight identified clusters extracted literature keywords, covering remote sensing, urban infrastructure, landscape patterns, spatial regression analysis, threshold values efficiency, etc., established specific content system, methodology. Furthermore, enhancing multi-disciplinary integration incorporating practical case will improve accuracy applicability facilitate translation theoretical into applications. This study provided comprehensive overview current offered valuable guidance studying thermal comfort sustainable development future.

Heat exposure poses a substantial public health threat. Increasing greenness has been suggested as mitigation strategy due to its cooling effect and potential modify the heat-mortality association. This study aimed comprehensively estimate effects of increased on heat-related deaths. We applied multistage meta-analytical approach reduction in global deaths by increasing warm season 2000-19 11 534 urban areas. used enhanced vegetation index (EVI) indicate random forest model predict daily temperatures counterfactual EVI scenarios. In factual scenarios, mortality weather variables from 830 locations 53 countries were extracted Multi-Country Multi-City Collaborative Research Network assess associations. These associations then extrapolated each area under both scenarios based meta-regression models. estimated that 10% would decrease population-weighted warm-season mean temperature 0·08°C, 20% 0·14°C, 30% 0·19°C. scenario, 3 153 225 (2·48%) 127 179 341 total could be attributed heat exposure. The attributable fraction (as deaths) 0·67 (95% empirical CI 0·53-0·82) percentage points 0·80 (0·63-0·97) 0·91 (0·72-1·10) compared with scenario. South Europe was modelled have largest mortality. modelling suggests substantially reduce burden.
