在第二篇论文的研究中,论文共同通讯作者、中国清华大学张强和郑博与合作者一起,利用一个机器学 习框架预测了全球到21世纪末的野火排放和相应的过早死亡,他们预计,从2010-2014年到2095-2099 年,火灾导致的全球碳排放可能在中等排放情景下增加23%。 他们的预测显示,到2095-2099年,野火烟雾导致的年过早死亡可能升至每年140万左右,几乎是当前水 平的6倍。在中等排放情景下,预计的健康负担存在明显差异,非洲预计会受到最重的影响(火灾相关死 亡预计为2010-2014年的11倍),而欧洲和美国的死亡率可能是原来的1到2倍。 这两项最新气候变化研究的结果共同表明,必须寻找有望降低火灾风险并减少野火烟雾健康负担的干预 措施。(完) 来源:中国新闻网 最新气候变化研究:野火烟雾造成超额和过早死亡人数预计会增加 中新网北京9月19日电 (记者 孙自法)国际知名学术期刊《自然》最新同时发表两篇气候变化建模研究论 文显示,与未来预测气候变化相关的野火增加,预计会显著增加超额和过早死亡。其中一篇论文认为, 在高排放情景下,到2050年,野火烟雾可能会导致美国每年约7万例超额死亡。另一篇论文指出,全球 范围内,2 ...

大华银行视角:东南亚能源转型,私资入场政策先行
Sou Hu Cai Jing· 2025-09-17 10:23
在全球聚焦气候变化议题的大背景下,《联合国气候变化框架公约》第二十九次缔约方大会(COP29) 成功达成重要协议。富裕国家将牵头,每年提供 3000 亿美元资金,助力较贫穷国家应对气候变化。对 此,大华银行集团企业可持续发展业务主管梅可嘉指出,这笔资金对于广大发展中国家而言,仍显不 足,发展中国家需从自身内部探寻解决方案,其中相关政策的有力支持尤为关键。 大华银行关注到,东南亚地区在能源转型方面形势紧迫。亚洲开发银行预估,东南亚每年需 2100 亿美 元资金,才能满足该区域可再生能源转型的需求。梅可嘉强调,东南亚 GDP 增长的同时,碳排放也在 惊人增长,其对可再生能源投资的需求极为迫切。目前,东南亚在可再生能源领域的产能建设远不能满 足需求,煤炭依旧是主要能源。国际能源署数据显示,自 2007 年以来,诸多发达经济体在 GDP 持续增 长的情况下,碳排放量不断降低,新兴经济体中这种 GDP 与排放量脱钩的现象也较为明显,如中国经 济规模大幅增长,排放量增长幅度却相对较小,非洲和拉丁美洲的经济活动与碳排放也呈现不同增长趋 势。然而,东南亚的 GDP 和排放量增长速度近乎相同。若不加快能源转型,到 2100 年 ...
气候变暖对热带森林有何影响?国际最新研究称或加快土壤呼吸
Zhong Guo Xin Wen Wang· 2025-09-17 08:53
Core Insights - The latest research published in the journal "Nature Communications" indicates that climate warming may accelerate soil respiration rates in tropical forests, leading to increased carbon loss from soil, which could impact global climate predictions [1][2] Group 1: Research Findings - A field experiment showed that soil respiration rates in warmed plots were found to be 42%-204% higher than in control plots, reaching some of the highest soil respiration rates reported in terrestrial ecosystems [2] - The additional carbon released from warmed plots was estimated to be between 6.5 to 81.7 tons per hectare annually, depending on the slope position, with the highest carbon release occurring in upper slope areas [2] - The authors suggest that these increases may be due to changes in the microbial community functions in warmed soils, affecting their ability to metabolize carbon or altering the composition of microbial communities [2] Group 2: Implications - The study's findings indicate that in a warmer world, tropical forest ecosystems may experience significant carbon loss, highlighting the importance of further research to understand the underlying mechanisms of these processes for assessing the long-term impacts of climate change [2]
