国际最新研究:全球海表温度过去1.2万年一直上升
全球 海表温度 1.2万年
2021/1/29
国际著名学术期刊《自然》最新发表一项气候科学的研究论文显示,全球海表温度在过去1.2万年里一直在上升。之前曾发现用来重建全新世历史气候变化的气候模型和数据之间存在差距,而此次最新研究帮助弥合了这种差距。该论文称,之前对历史气候的重建都是基于保存下来的地质资料,这些重建显示,气温在约6000年前曾出现过一个暖峰,但之后便一路下降到工业时代。不过,这些重建结果与长期气候模拟并不一致,长期模拟显示该时期...
国际著名学术期刊《自然》最新发表一篇动物学研究论文称,自1970年以来,全世界的海洋板鳃鱼(鲨、鳐、鲼、魟)减少了71%。这项研究还发现,这些海洋物种中有四分之三以上正处于濒临灭绝的状态。该论文指出,海洋物种的灭绝风险主要来自过度捕捞,然而个别物种的减少向来很难测量。虽然之前记录过全球不同地区的海洋和海岸板鳃鱼种群的减少情况,但一直没有开展过全球性的分析。

《自然》论文:21世纪末湖泊热浪或将增加覆盖所有季节
21世纪末 湖泊热浪 增加覆盖 所有季节
2021/1/22
国际著名学术期刊《自然》最新发表一项气候变化的模型研究论文称,到21世纪末,湖泊热浪(湖面水温极热的时期、强度和持续时间)或将增加,并将覆盖所有季节。这项研究显示,在温室气体高排放情景下,湖泊热浪的平均持续时间或增加3个月左右,一些湖泊可能会进入永久性的热浪状态。该论文指,陆地和海洋表面的热浪频率增加被认为和全球变暖有关。但是,关于湖泊热浪以及它们如何受到全球变暖的影响仍存在认知空白。湖泊生态系统...

研究发现一种深海食肉海绵可以自身发光
深海食肉海绵 自身发光
2020/12/28
研究人员在2017年利用远程控制机器人在海底4000米的黑暗深处探索到了一种奇特的生物,可发出蓝绿色光,经研究发现,这是一块发光的深海海绵。虽然许多深海动物会发光,但海绵一直被认为是个例外。在过去的100年里,一些海洋生物学家发现了疑似可发光的海绵,事实证明,这些海绵中含有发光细菌,或者曾经食用过或被其他发光动物占据过。
