今年是国际冰川保护年。随着全球气候变暖，人们对冰川的关注逐渐提升，但其消融的速度却在加速。 数据显示，我国冰川60年间消失约26%，联合国教科文组织报告提示，到2050年被列为世界遗产的冰川 有三分之一将消失。 与此同时，冰川消融形成的冰湖持续增加，这些新生水体正迅速演变为独特的高寒水生生态系统。如果 它们发生溃决，可能对下游造成重大灾害；而冰川快速消融会导致冰湖和下游水质突变，进而对区域内 脆弱的生态产生影响；冰湖水体的盐度、酸碱度的变化，还可能导致区域生物多样性锐减。 厘清冰湖的水环境变化规律，是科学保护和系统管理这些脆弱水体、维系下游生态安全的基础。但冰湖 形成速度快、数量多、变化迅速，科学家对它们的规律了解却才刚开始。如何找到有效、高效的监测方 法，是科学家们面临的难题。 往天上"走"5公里最怕没采集到有效数据 "目前青藏高原上约有2万个冰湖，还在不断增加。"说这话时，张强弓有些迫切。他是中国科学院青藏 高原研究所研究员，最初研究冰川和气候环境变化，但随着冰川消融，他发现自己的研究对象在逐渐消 失。茫然中，他惊觉冰湖的变化蕴含着许多未知的奥秘，和气候环境变化有关。"同一个海拔下，已经 有下游的放牧业受 ...

加拿大之所以出台这样针对中国的政策，与美加之间持续不断的贸易摩擦密切相关。今年6月中旬，美国再次挥动关税大棒，对加拿大 的钢铁、铝制品等商品开出最高50%的惩罚税率。加拿大政府原以为，满足特朗普的要求，就能换来些许宽容，于是迅速取消了对美国 科技企业的数字服务税，并承诺增加国防与边境安全预算。然而结果却不尽如人意，7月10日，特朗普公开宣布，自8月起对加拿大商品 加征35%的关税 ，还直言不讳地批评加拿大在芬太尼问题上不配合。 据新京报报道，当地时间7月16日，加拿大财政部网站发布公告，宣布一系列加严钢铁进口限制措施。消息一出，国际舆论一片哗然， 中加经贸关系也因此蒙上一层阴影。 加拿大此次加严钢铁进口限制措施，主要针对对象便是中国。根据规定，自8月1日起，对自美国以外国家进口的含有在中国熔化和浇铸 钢铁的产品，将征收25%的附加税。不仅如此，加拿大还对钢铁进口配额进行了严格限制，要求中国今年出口到加拿大的钢铁产品不能 超过去年进口量的一半，超出部分还要额外征收50%的关税 。 值得一提的是，美国在这一系列政策中得到了完全豁免。2024年，加拿大钢铁进口总额为160亿美元，其中接近一半来自美国，而中国 只占1 ...
