海温上升让飓风持续更长
海温上升 飓风 持续更长
2020/11/12
不断上升的海洋温度正导致飓风持续时间更长，北大西洋飓风平均需要33个小时才能减弱，而大约50年前只有17个小时。11月12日，《自然》发表的一篇论文指出，由于海水温度上升，北大西洋飓风在登陆后的减弱速度较过去有所放缓。这一研究结果表明，飓风的破坏性影响今后可能会进一步向更远的内陆地区扩展。

The waters of the Gulf of Maine are warming faster than oceans almost anywhere on Earth. As the level of carbon dioxide rises in the atmosphere, it's absorbed by the sea, causing pH levels to fall. Oc...

海洋热浪会造成生态系统“重新分布”
海洋热浪 生态系统 重新分布
2020/8/6
美国国家海洋和大气管理局（NOAA）的科学家衡量了海洋热浪造成的生态系统破坏，结果发现，海洋热浪会造成热位移，位移距离从数十公里到数千公里不等。而这种位移，代表了生物为躲避潜在的高温胁迫可能需要移动的距离。该结果开辟了新的研究方向，有助理解反常的海水变暖对于海洋物种的潜在影响。相关研究报告发表于5日的《自然》杂志上。
随着北极海冰每十年进一步退缩、融化速度加快，科学家正竞相了解这个世界上最偏远、最严酷地区之一的脆弱性。7月29日发表在 Cell Press细胞出版社旗下期刊Heliyon上的一项研究详细描述了2018年9月北极发生的变化。这年夏天，近1000万千米的北极海冰消失。他们的发现概述了在卫星时代的40年里不同时间段海冰是如何消退的，并显示了夏季海冰的大规模减少是如何与遥远热带的全球大气进程相联系的。

近日，一项研究预测称，在温室气体排放量维持在高位的情况下，北极熊可能会在2100年之前灭绝。据英国广播公司（BBC）20日报道，非营利组织动物保护组织——北极熊国际（Polar Bears International）的一项研究预测称，除非人类采取更多措施应对气候变化，否则北极熊将在本世纪末灭绝。北极熊通常依靠北冰洋的海冰来寻找海豹以供觅食，不幸的是，随着海冰融化，这些北极熊被迫游很长一段距离来觅...

气候变暖 六成鱼类 无法生存 气候变化
2020/7/8
气候变化为鱼类带来的风险远比此前认为的要大得多，研究人员近日在《科学》发表的研究表明，鱼类胚胎和产卵的成年鱼更容易受到海洋变暖的影响。在全球变暖5℃的最坏情况下，考虑到鱼类生活的不同阶段，到2100年，全世界多达60%的鱼类将无法适应其地理范围内的温度。就算人类实现了《巴黎协定》的严格目标，将全球变暖控制在1.5℃，但对于10%的鱼类来说，这一温度依然太高了。
