气温上升正在加速美国北部的授粉者下降 威胁到粮食安全 Rising temperatures are speeding pollinator decline in the northern U.S., threatening food security.

2025年11月6日发布的一项新研究发现,气温上升正在加速美国北部授粉者人口的下降,过去十年来蜜蜂和蝴蝶的数量明显下降。 A new study released on November 6, 2025, finds that rising temperatures are accelerating the decline of pollinator populations across the northern United States, with bees and butterflies showing significant drops in numbers over the past decade. 研究者将这种趋势归因于更长时间的热浪和中断的花朵循环,这干扰了授粉者的喂养和繁殖模式。 Researchers attribute the trend to longer heatwaves and disrupted flowering cycles, which interfere with pollinators’ feeding and breeding patterns. 调查结果基于120个监测地点的数据,突显了对粮食安全和生态系统健康的日益关切。 The findings, based on data from 120 monitoring sites, highlight growing concerns about food security and ecosystem health. 科学家敦促立即采取行动,以保护生境和减少气候影响。 Scientists urge immediate action to protect habitats and reduce climate impacts.
