Study warns of longer extreme heat periods by century's end_我的网站

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)                    。原告是一名当地养牛农户，每日在山里、田里放养牛群。2024年1月9日，其发现养殖的一头黑色小黄牛丢失，三日后，在被告院子中发现一头黑色黄牛。因原告曾在黑色黄牛耳朵处做标记，其认为被告院子中的黑色黄牛就是自己丢失的那头，于是找到被告据理力争，要求返还。

B | 但双方均笃定该黑色黄牛系自家所养，争执不下后，原告遂向闽清法院白樟法庭提起诉讼。案件受理后，原告随即申请为小牛进行亲子鉴定。“鉴定费1万元，费用不低。若亲子鉴定结果显示小牛与原告家的牛具有亲子关系，被告不仅要返还黑色黄牛，还需要支付鉴定费用、诉讼费等费用；若亲子鉴定结果显示不具有亲子关系，原告要承担鉴定费用。
