Nevertheless, a critical gap in knowledge persists regarding the specific physical processes involved in the mitigation provided by these coverings. This study explores the underlying mechanisms that govern the interaction through field observations and COSIPY model simulations at Bailanghe Glacier No. 21 in the Qilian Mountains from 26 June to September 17, 2023. It compares covered and uncovered areas to evaluate differences in mass and energy balance fluxes. It was discovered that geotextiles could decrease ice melt by up to 1000 mm w.e. in comparison to the surface of glaciers without cover, primarily because of a 23% increase in albedo compared to ice, leading to a decrease in net short-wave radiation and available melt energy. The effect of covering the entire glacier with a geotextile, which has varying albedo properties, was also simulated. It was found that, with every 5% increase in the albedo of the geotextile, ablation was reduced by 10%–25%, resulting in a decrease in ice volume loss of approximately 2.5 × 10⁵ m³. While artificially covering glaciers can reduce ablation rates, it faces challenges such as high costs, environmental risks, and issues with replicability. Ultimately, this study aims to analyze the feasibility of glacier coverage from a mechanistic perspective for glacier management amidst ongoing climate change.</div></div>","PeriodicalId":48628,"journal":{"name":"Advances in Climate Change Research","volume":"15 6","pages":"Pages 1147-1159"},"PeriodicalIF":6.4,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143342412","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we performed a detection and attribution analysis of the changes in the ETR over the land areas of the Northern Hemisphere (NH) for the period 1960–2018, based on the optimal fingerprinting approach. We found that anthropogenic forcing could be detected and separated from natural forcing, and greenhouse gas forcing could be detected and separated from anthropogenic aerosol forcing, in the spatiotemporal pattern of the NH and in the regional average of the high latitudes. It is estimated that anthropogenic forcing (greenhouse gas emissions) contributed to 129% (152%) of the significant decreasing trend in the NH-averaged ETR. Moreover, compared to the average of 1999–2018, the NH (North America)-averaged ETR was projected to further significantly decrease by 6.7 °C (14.0 °C) in 2081–2100 under the SSP5-8.5 scenario, based on attribution-constrained projection, the magnitude of which was larger than in the models’ raw outputs. In contrast, the ETR was projected to increase significantly in the Mediterranean and adjacent regions under the SSP5-8.5 scenario, and in Central Europe, West Africa, Central Asia, South Asia, and parts of China under the SSP1-1.9 scenario.

The records of 399,214 decedents aged 60 years and older who died due to AD or other dementias from 2013 to 2020 were obtained from the China Cause of Death Reporting System.

In addition, the attributable fractions (AFs) of mortality due to non-optimal ambient temperatures were calculated. The study found that both low and high non-optimal temperatures were associated with an increased risk of death from AD and other dementias, with an inverted J-shaped exposure–response curve. Moreover, the AFs of mortality due to full, low and high non-optimal temperatures with lag0–14 were 5.81% (95% empirical confidence interval [eCI]: 4.89%, 6.72%), 5.24% (95% eCI: 4.15%, 6.27%) and 0.58% (95% eCI: 0.27%, 0.90%), respectively.

However, existing studies mainly analyse the characteristics and causes of NSWS changes on regional scales and over short periods. The decadal variations and underlying causes of global NSWS changes over long timescales remain underexplored. In this study, we investigated the characteristics of NSWS changes in the Northern Hemisphere (NH) on a centennial scale (1900–2010) and identify the potential causes of decadal variations by using an information flow technique. The results indicate that NSWS in the NH experienced a remarkable decadal variation, increasing during 1900–1945 and 1970–1980 and decreasing during 1945–1970 and 1980–2010. Furthermore, regional differences in the distribution features and decadal variations of NSWS were observed. Asia and North America showed the highest data overlap compared to other regions, reaching 59.4%. The longest period of decadal variation in NSWS was found in North America (14 years), followed by Europe (11 years), with Asia showing the smallest period (10 years). When determining the effects of large-scale ocean–atmosphere circulation fields or internal climate models on NSWS changes, prioritising causality between the two variables and the study period is essential, rather than relying solely on simple correlation analysis. According to the information flow technique, the decadal variations in NSWS over North America during 1950–2010 were linked with the Western Hemisphere Warm Pool, whereas the North Atlantic Oscillation influenced those in Europe. The Tropical Northern Atlantic was the driver over Asia. This study offers a scientific foundation for understanding NSWS characteristics on a centennial timescale and the primary causes of decadal variations in NSWS across the NH.</div></div>","PeriodicalId":48628,"journal":{"name":"Advances in Climate Change Research","volume":"15 6","pages":"Pages 1003-1012"},"PeriodicalIF":6.4,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143342370","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is essential to develop representative CO₂ emissions pathways at the provincial level that align with the national target to facilitate effective policy implementation and scientific research. To address inconsistencies between provincial aggregate emissions and national estimates, this study compares the 2021 CO₂ emissions estimates of China's provinces from the bottom‒up emissions factor method and the top‒down atmospheric CO₂ concentration inversion method. We find that these methods yield comparable results for the emissions from energy combustion and industrial processes at the provincial level. Based on a review of existing research on CO₂ pathways for China's provinces, we propose a set of representative pathways for China's provinces. These pathways align with past practices of allocating national emissions intensity reduction targets to provinces and are consistent with the national Tsinghua‒CMA pathway. The proposed pathways require provinces to sequentially peak their emissions by 2030, followed by rapid emissions reduction. Compared to a reference scenario without the carbon neutrality target, these pathways would incur an estimated cumulative GDP loss of about 1% between 2020 and 2060. However, there are notable regional variations, with some regions in the northwest potentially experiencing higher economic growth due to the availability of high-quality low-carbon resources. We recommend that China enhance provincial-level CO₂ emissions accounting by cross-validating bottom‒up and top‒down methods. Additionally, careful consideration should be given to aligning provincial targets with national and global commitments when updating pathways toward carbon neutrality.</div></div>","PeriodicalId":48628,"journal":{"name":"Advances in Climate Change Research","volume":"15 6","pages":"Pages 1096-1106"},"PeriodicalIF":6.4,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143342133","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we develop a new approach to evaluate regional permafrost changes, which does not rely on spatially distributed meteorological data but instead uses the regional climate change processes or temperature change rates. Centred on a transient heat conduction permafrost model, this approach was applied to the Qinghai Hoh Xil National Nature Reserve (referred to as Hoh Xil) within the QTP from 1960 to 2015, using the rate of air temperature change provided by the Wudaoliang Meteorological Station, the only national station in Hoh Xil. Simulation results showed that the difference between the simulated and observed change rates of mean annual ground temperature (MAGT) was less than 0.04 °C per decade from 2001 to 2015 at five long-term monitoring sites. The simulated ground temperature profiles in four boreholes from various permafrost zones revealed an error of less than 0.7 °C below 5 m in depth. Model validation demonstrates the reliability of this approach for predicting long-term permafrost changes. Future regional permafrost changes were further simulated based on the latest warming scenarios (BCC-CSM2-MR) from the Coupled Model Intercomparison Project Phase 6. Predictions revealed significant differences in the regional permafrost degradation rate under different climate warming scenarios. Under the most severe warming scenario (SSP5-8.5), permafrost in the study area is projected to still cover 72.2% of the total area by 2100, with most of the Hoh Xil's permafrost becoming warm (MAGT &gt; −1 °C) permafrost.
