A | (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) 
。1月15日新闻：今天是个特别的日子。今天的头条新闻是，王欣和罗永浩对快速技术的投资将分别发布三种新的社会产品。众所周知，今天的头条新闻将推出多功能闪光灯。王鑫的云歌人工智能技术将推出马桶山，快如科技将推出聊天宝。这三款产品都是针对微信的。上午10点30分在深圳举行的厕所山地会议上，演讲人是王鑫。产品为MT厕所。口号是“让我们换个方式谈谈”。下午2点30分在北京举行的字节跳跃大会上，演讲者张一鸣，产品可能是多闪，口号是“这是一个年轻人”。
B | 北京快如科技下午5:30新闻发布会。子弹聊天的主要演讲者是罗永浩，锤技术。该产品被怀疑更名为朝宝。口号是“我们想和世界聊天”。你喜欢谁？。
