Nat Commun:预测中国在气候变化过程中与变暖相关的死亡现象 

2021-02-16 haibei MedSci原创

最近,研究人员使用28个全球气候模型(GCMs),在两个代表性的浓度路径(RCPs)下,预测了中国161个区/县未来高温造成的超额死亡率、年龄、地区和教育相关的死亡率。

最近的研究报告了气候变化的各种健康后果。然而,个人和城市对气候变化的脆弱性还有待评估。

最近,研究人员使用28个全球气候模型(GCMs),在两个代表性的浓度路径(RCPs)下,预测了中国161个区/县未来高温造成的超额死亡率、年龄、地区和教育相关的死亡率。

为了评估人口老龄化对未来高温相关死亡率预测的影响,研究人员进一步预测了5条共同社会经济路径下的年龄效应估计。在RCP8.5下,与热相关的超额死亡率预计将从2010年代的1.9%(95% eCI:0.2-3.3%)增加到2030年代的2.4%(0.4-4.1%)和2090年代的5.5%(0.5-9.9%),相应的相对变化为0.5%(0.0-1.2%)和3.6%(-0.5-7.5%)。

华南、华东、华中和华北地区的预测斜率较陡。患有心肺疾病的人、女性、老年人和低教育程度的人可能会受到更大的影响。在不同的可持续发展战略目标下,人口老龄化会使未来与热相关的过量死亡扩大2.3-5.8倍,尤其是东北地区。

因此,该研究结果有助于指导公共卫生对策,以改善气候变化的风险。

研究发现:气候变暖将导致能举办冬奥会的地点越来越少

根据安大略滑铁卢大学地理学教授丹尼尔·斯科特(Daniel Scott)领导的国际研究小组的研究,之前举办过冬季奥运会的9个地点在2050年之后冬天可能会过热,无法再次主办奥运会。斯科特的研究最初是在2014年发表的,但最近更新了包括今年东道主平昌的数据以及2020年奥运会主办方北京的数据。sochi-2014-262145_960_720.jpg这项研究解释了造雪和事件协调员为解决温度升高的影响

气候变暖或促进沙门氏菌爆发

沙门氏菌是一类相对常见的致病菌,其中的一些种类可能造成人类呕吐、发烧和腹泻等症状。而且这种菌常常因为不严格的卫生条件,而被混进食物中导致人们的食物中毒。以前有研究认为,这类菌的突然大量爆发可能与极端的天气相关,但是具体情况还需要进一步验证。美国马里兰州的研究者们分析了过去十年来沙门氏菌的数据,他们将天气与沙门氏菌的爆发建立起了联系。他们的研究认为,过去十年内的气候变暖趋势下导致了一些极端的气候情况

中国疾控:气候变暖致全球登革热病例偏高

在10月9日举行的中国国家卫生计生委新闻发布会上,卫计委宣传司副司长宋树立通报,截止到10月8日,中国今年一共报告登革热病例27219例,死亡6人,相比去年同期疫情明显上升,目前输入性病例仍然是中国登革热的主要原因。 全球登革热病例普遍偏高 宋树立介绍说,今年中国的登革热疫情来得较早且较为严重,原因主要有三点。首先是因为中国与东南亚人员来往越加频繁,部分东南亚国家登革热疫情上升,导
