日本核污染水排海给经济复苏添堵
日本 核污染水 海洋环境 经济复苏
<
2023/8/7
日本政府强推核污染水排海是对民意的无视，也是对自身责任的推脱。海洋污染等环境问题既是事关人类健康的安全问题也是经济问题。日本强排核污染水入海不仅将严重打击本国水产业等关联行业，也将给全球经济带来隐忧。
2023年1月11日，由中国科学院大气物理研究所牵头，联合国家海洋环境预报中心、中国科学院海洋研究所等全球16个研究单位的24位科学家组成的国际研究团队，在《ADVANCES IN ATMOSPHERIC SCIENCES》（AAS）发布了涵盖2022整年的全球海洋环境（温度和热含量、盐度、层结）变化研究报告。新的研究指出：2022年海洋升温持续——成为有现代海洋观测记录以来海洋最暖的一年。同时，...
