散布着“冰棒”的云层听上去像是来自童话故事。不过，这一现象已在英国和北大西洋的云系中被发现。
2016年9月，科学家在经过东北大西洋上空的研究飞行中看到了这些稀奇的冰构造（形状像一根末端有着球形头的棍）大量聚集。此前，该现象还于2009年1月在英国西南部被观察到。来自曼彻斯特大学的Stavros Keppas及其同事在日前出版的《地球物理研究快报》上发表了来自两次飞行的研究结果。

水有力地塑造了美国加利福尼亚州——厄尔尼诺带来的降雨使该州洪水泛滥，严重的干旱则将其蒸干。如今，一项最新研究表明，水或许还扮演了另一重角色：触发地震。
刚从加州大学伯克利分校博士毕业的地球物理学家Christopher Johnson和同事收集了来自由661个散布在加州的GPS传感器构成的网络的数据。这些组件敏感到足以探测出水的重量、地下水开采、潮汐和其他因素导致地面何时上升或下降了几毫米。随后...
