Flexible strategies that adjust in real time reduce losses by up to 86%, offering both responsiveness and cost-efficiency. The reduction in losses is especially notable in economically developed provinces such as Shanghai (95%), Jiangsu (91%), and Zhejiang (89%), where dense populations and high-value assets increase the benefits of effective adaptation.

Previous urban studies have typically focused on either carbon reduction or air pollution control independently, but few have examined their combined effects on reducing carbon emissions and consequential environmental gains. We develop an integrated modelling framework to assess the impacts of different low-carbon transitions and end-of-pipe controls on PM<sub>2.5</sub> and ozone concentrations and associated premature mortality in the megacity of Guangzhou. The results show that the implementation of both deep carbon mitigation and aggressive air pollution control policies can reduce the city's pollutant emissions to 34%–51% of the 2020 levels by 2035. Consequently, the population-weighted PM<sub>2.5</sub> concentration in 2035 is projected to decrease by 5 μg/m<sup>3</sup> compared to the 2035 baseline scenario. However, the ozone concentration is expected to rise by 35 μg/m<sup>3</sup> due to the reduced titration effect of NO on ozone. These changes are estimated to prevent approximately 3.0 thousand (95% CI: 2.0–3.9) PM<sub>2.5</sub>-related premature deaths, while increasing ozone-related premature deaths by approximately 1.6 thousand (95% CI: 0.7–2.7). Moreover, implementing multiregional integrated control measures in Guangzhou and its neighbouring cities yields greater air quality and health benefits for Guangzhou compared to local enforcement alone, resulting in 1.5 times more avoided PM<sub>2.5</sub>-related premature deaths. Additionally, the increase in ozone-related premature deaths from these cooperative emission control strategies is merely 0.3 times the figure observed under local enforcement alone. The transport and industry sectors play a crucial role in reducing air pollutant emissions, whereas reductions in the solvent use sector can help mitigate the adverse effects of reduced NO<sub>x</sub> on ozone pollution.

Here, we utilise multiple observational data and simulations from the Coupled Model Intercomparison Project Phase 6 to investigate the influence of external forcing and low-frequency climate variability from sea surface temperature on the changes in daily maximum (Tmax), minimum temperature (Tmin) and their difference (diurnal temperature range, DTR) during the period of 1901–2020. We find that the warming trends in East Asia differ across seasons, with the warming magnitudes in spring and winter greater than those in the other two seasons. Detection and attribution based on an optimal fingerprinting method show that anthropogenic forcing mainly explains the observed changes in Tmax and Tmin during 1901–2020. Greenhouse gas forcing contributes approximately 1.1 °C (90% confidence intervals (CI): 0.78–1.3 °C) and 1.4 °C (90% CI: 1.19–1.58 °C) of annual Tmax and Tmin changes, while the anthropogenic aerosol forcing offsets 0.47 °C (90% CI: 0.15–0.92 °C) and 0.4 °C (90% CI: 0.07–0.77 °C) of the warming.

This study evaluates the impacts of two SRM strategies on precipitation extremes in Southeast Asia, using the multi-model ensemble mean from five climate models in the Geoengineering Model Intercomparison Project Phase 6 (GeoMIP6). Under a high-emission scenario (SSP585), two SRM approaches are tested: injecting sulfur dioxide (G6sulfur) into the stratosphere and reducing the solar constant (G6solar) to maintain radiative forcing at the level of a moderate-emission scenario (SSP245). Bilinear interpolation and linear scaling were used to downscale and bias-correct daily precipitation data before calculating precipitation extreme indices, respectively. The results show that G6sulfur causes more regional variation in annual total and mean wet day precipitation, the average daily precipitation on days with ≥1 mm rainfall, compared to G6solar. In areas like central Borneo, northern mainland Southeast Asia, and eastern Indonesia, the annual maximum 1-d precipitation per year is projected to increase by 30%–50% under SSP585 relative to the historical 1995–2014 baseline period but this rise could be reduced to around 20% by SSP245, G6sulfur, or G6solar. G6sulfur has less influence on continuous wet and dry spells than G6solar, yielding results closer to SSP585. Both SRM strategies lower the projected increase in heavy precipitation days, except in areas like East Coast Peninsular Malaysia, Nusantara Indonesia, and East Timor.

However, research on STC is hindered by insufficient <em>in-situ</em> measurements. To address this gap, we conducted <em>in-situ</em> measurements of STC at soil depths of 0–40 cm across 58 plots at 12 sites in the TRSR (244 records) during July and August 2023. The driving mechanisms influencing STC variations were further analyzed through laboratory experiments in September and October 2023. Spatially, STC increases from west to east and vertically with soil depth. Control experiments revealed that STC at negative temperatures is markedly higher than that at positive temperatures and increases with volumetric moisture content, particularly in inorganic soils, sand and loamy sand. This effect is more pronounced at subzero temperatures. Meanwhile, our results show that an artificial neural network model (<em>R</em><sup>2</sup> = 0.78, <em>p</em> &lt; 0.0001) incorporating ten measured soil physical parameters, outperforms traditional theoretical and empirical models in predicting STC. These findings contribute to a deeper understanding of permafrost formation, evolution, and its responses to climate change in the TRSR.</div></div>","PeriodicalId":48628,"journal":{"name":"Advances in Climate Change Research","volume":"16 3","pages":"Pages 552-564"},"PeriodicalIF":6.4,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144491959","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
