中国工程院院士、歼轰7飞机总设计师陈一坚逝世，享年96岁_我的网站

一 |          (ECNS) -- Hot days worldwide could experience around four additional hours of extreme heat by the end of the 21st century under a high-emissions scenario, according to a study led by Chinese researchers.    Published in Nature Climate Change, the study found that traditional daily temperature indicators may overlook shorter periods of extreme heat, while hourly temperature analysis can provide a more detailed picture of heat exposure and associated risks.        Researchers from Sun Yat-sen University and other institutions analyzed global hourly temperature data from 1981 to 2023, combining observational records with climate model projections to assess how extreme heat exposure could change in the future.    The research team found that the duration of extreme heat increased by 62 hours per decade over the study period. Around 28% of extreme heat events occurred on days that would not have been classified as hot days based on conventional daily temperature indicators.    Under a high-emissions scenario known as SSP5-8.5, the researchers projected that between 2070 and 2099, each hot day could experience around four additional hours of extreme heat compared with the 2001-2023 period. Days not classified as hot could also see increased periods of extreme heat.    The study also found that low- and middle-income countries account for a disproportionately large share of both current and projected extreme heat exposure. Younger generations in low-income countries are expected to experience the greatest increase in lifetime exposure.    Researchers said the findings could help improve heat-warning systems, strengthen assessments of health risks and support climate adaptation efforts.    (By Helen Mo, intern Liu Shuangjing)                    。    中国航空工业集团消息，陈一坚院士治丧工作委员会发布讣告，中国共产党党员、中国工程院院士、603所原总设计师、歼轰7飞机总设计师陈一坚同志，因病医治无效于2026年8月24日7时50分，在西安逝世，享年96岁。讣告中国共产党党员、中国工程院院士、603所原总设计师、歼轰7飞机总设计师陈一坚同志，因病医治无效于2026年8月24日7时50分，在西安逝世，享年96岁。陈一坚同志遗体告别仪式定于2026年8月30日9时30分在西安市殡仪馆咸宁厅举行。
