This study evaluates key climatic risks and their overlaps, including heavy storms, heatwaves, and droughts, that may affect the Beautiful China Initiative objectives in 2035 and 2050. The analysis is based on three shared socioeconomic pathways (SSP126, SSP370, and SSP585), incorporating vulnerability, disaster risks, and exposure levels. The findings indicate that the severity of climatic risks in China will intensify over time and with climate warming. The western regions will face more severe single-climate risks, while the eastern regions will encounter increasingly severe comprehensive climatic risks. In the western regions, by 2035, the Tarim Basin in Xinjiang is projected to experience heatwave risks exceeding Level 5, while Tibet and Qinghai will face drought risks above Level 6. By 2050, more areas will escalate to Level 6 and 7 risks. In the eastern regions, by 2035, Shandong, Henan, the Pearl River Delta, and the Beijing, Tianjin, Hebei region are expected to face comprehensive risks from heavy storms, heatwaves, and droughts. By 2050, the overlapping high-risk areas will expand, covering the eastern parts of the Yangtze River Economic Belt. Furthermore, higher radiative forcing scenarios are associated with increased risks. This study provides critical insights for developing targeted disaster prevention and management systems across different regions of China, offering guidance for the effective implementation of the Beautiful China Initiative.</div></div>","PeriodicalId":48628,"journal":{"name":"Advances in Climate Change Research","volume":"16 1","pages":"Pages 141-153"},"PeriodicalIF":6.4,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143679489","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}

However, a comprehensive quantification of the precise effects of climate change on electricity consumption in China's urban residential buildings has been hampered by the scarcity of data. Here, we employ a verified county-level unbalanced panel dataset to estimate the effect of cooling degree days (CDD) and heating degree days (HDD) on the electricity consumption of urban residential buildings in China. The results indicate that a 1% increase in CDD and HDD is linked to a corresponding rise of 0.114% and 0.457% in electricity consumption per unit of floor space in urban residential buildings, respectively. However, these effects are diminished as income increases, implying residents have more strategies to adapt to climate change as income rises. The impacts of temperature fluctuations exhibit variability across different climate zones, building heights, and construction years. Specifically, buildings in regions characterized by hot summers and cold winters, as well as those with hot summers and warm winters, exhibit greater sensitivity to temperature fluctuations compared to the buildings located in regions with severe cold and predominantly cold climates. Additionally, low-rise buildings tend to consume more electricity than multi-story and mid-to-high-rise buildings in response to temperature variation. Interestingly, new buildings are more vulnerable to temperature fluctuations than older buildings. These findings offer a comprehensive and accurate assessment of climatic impacts in different climate zones, enabling a more profound comprehension of climate change.

This study systematically examines the surface elevation, flow velocity, morphological changes, and climate responses for different tributary glaciers of the Musta Glacier, using multi-source remote sensing imagery and meteorological reanalysis data from 1976 to 2023. The findings reveal that the tributaries of Musta Glacier experienced a total of nine surges, with an average duration exceeding ten years. These surges typically began in spring and summer and concluded in summer and autumn. During these events, the glaciers transferred an estimated 1.32 km³ of material downstream, resulting in an average thickening of over 30 m in the receiving area. The analysis of velocities reveals that the acceleration phase of Musta Glacier tributary surges ranges from 1 to 12 years, with an average duration exceeding 6 years, while the deceleration phase consistently lasts less than 4 years. Among the tributaries, the South Chongtar Glacier exhibits the most rapid surge dynamics, with a total surge duration of just 5 years. Additionally, all surging tributaries of Musta Glacier induce notable geomorphic changes during their surge events, including the formation of ring-shaped moraines and terminal advances. Comparative analysis with previous studies reveals that the surge characteristics of most Musta Glacier tributaries resemble those of thermally controlled Svalbard-type surging glaciers. Furthermore, we observed that the surging patterns of Musta Glacier are closely linked to regional climatic variations, characterized by increased precipitation and noticeably cooling prior to surge initiation. On the other hand, we proposed that the asynchronous surging behavior among the tributaries of Musta Glacier is primarily driven by variations in the internal dynamic processes of each glacier in response to climatic changes.

The overall development context and challenges comprising technological pathways, investment, value added, employment and inequality must be considered. For the case of Indonesia, as one of the world's largest coal-producing, the archipelagic nature with various island topography, sociocultural diversity as well as very high population really needs a comprehensive energy transition research considering the above aspects, which is so far still lacking. Therefore, this current study presents an integrated assessment of technological change and socioeconomics impact for power transition pathways in Indonesia using the Integrated MARKAL-EFOM System (TIMES) and their socioeconomics implications using the Miyazawa Input–Output Model (MIOM). Four scenarios were applied namely business-as-usual (BAU), 100% renewable energy (100%RE), Paris Agreement 1.5 °C without coal phase-out (PA1.5), and that of with coal phase-out (PA1.5PO). The results show that by 2060, 100%RE without applying carbon capture and storage (CCS) creates an extreme power flexibility which requires ample energy storage but does not attain net-zero. To meet the 1.5 °C carbon budget, PA1.5 and PA1.5PO require substantial renewable energy deployment, particularly in utility-scale solar PV, energy storage, and low-carbon technologies. These two scenarios exhibit a notable increase in total installed capacity, ranging 3.37–3.83 times higher than the BAU scenario. PA1.5PO, plays an increasing role natural gas as bridge fuel in advanced gas power from 2035 to its peak in 2050. PA scenarios require a higher installed capacity compared to BAU, corresponding to a substantial total investment cost of almost 2.5 times in 2060. The MIOM results show that these scenarios have a stronger impact on household income and employment compared to BAU. However, the impact on value added (VA) only surpasses BAU until 2045, specifically in the PA1.5PO scenario. In the long term, PA1.5PO generates the highest value added and household income, whereas 100%RE scenario has the highest employment and the highest value added in the electricity sector. In contrast, non-energy sectors related to conventional energy supply chains may face challenges. However, PA1.5PO can better mitigate adverse effects. The key findings could provide an insight for policymakers better understand transition pathway and its socioeconomic impacts to ensure a fair transition towards a carbon-neutral economy.</div></div>","PeriodicalId":48628,"journal":{"name":"Advances in Climate Change Research","volume":"15 6","pages":"Pages 1107-1120"},"PeriodicalIF":6.4,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143342132","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}

Global cognitive performance and its two dimensions (episodic memory and mental status) was measured using standardized questionnaires. Temperature exposure prior to cognitive tests was assessed using both average temperatures and heat days exceeding predefined temperature thresholds. Linear mixed-effects models were utilized to examine the relationship between high temperature exposure and cognitive function. This study revealed consistent evidence for heat-related declines in global cognitive performance and episodic memory across multiple exposure-window analyses, while robust associations were observed solely during prolonged exposure periods (more than 90 d) for mental status.

It compares the water consumption of current production processes with future hydrogen-based and advanced water-saving technologies. By developing a model, the study analyses the water-saving potential of 54 water-saving and hydrogen-based technologies across three water consumption scenarios and evaluates their impact on industrial water use. This study highlights the pivotal role of water-saving technologies in transforming industrial sectors, particularly in the paper and textile industries, where zero-emission technologies have considerably reduced water demand. Water savings in the paper industry are projected to increase from 24.29 Mt in 2025 to 101.44 Mt in 2050, representing an 8.5% increase. In the chemical fibre sector, additional water savings are expected to reach 106.93 Mt by 2050, with an 11.6% increase in water-saving efficiency. Similarly, the textile dyeing and finishing sector is anticipated to achieve an additional water saving of 26.45 Mt by 2050, corresponding to a 17.5% improvement. The findings indicate that the adoption of hydrogen-based technologies will considerably reduce water consumption in traditionally high-water-consuming industries such as steel, synthetic ammonia, ethylene, and methanol. This reduction becomes particularly evident by 2050 under the baseline pathway and low water consumption scenarios, in which the impact of water-saving technologies becomes less prominent. By 2050, water consumption in the steel, ethylene, synthetic ammonia, and methanol industries is projected to decrease to 985.93, 59.11, 242.4, and 268.29 Mt, respectively.

The findings indicated that the VIE thermosyphon exhibited excellent cooling performance and maintained uniform wall temperature, with the lowest wall temperature reaching −15 °C. Within one year of implementation, a cold core of −2 °C formed at the centre of the foundation, and the permafrost table was uplifted by approximately 3 m, showcasing its potential to rapidly enhance the thermal stability of in-service EBTS in permafrost. With prolonged operation, the cold accumulative effect of this approach gradually becomes apparent, and the range of the low-temperature cores expands. This method effectively reinforces the thermal stability of in-service EBTS and is well-suited for future railway construction in warm permafrost amidst the challenges of climate change.</div></div>","PeriodicalId":48628,"journal":{"name":"Advances in Climate Change Research","volume":"15 6","pages":"Pages 1160-1176"},"PeriodicalIF":6.4,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143341962","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}
