南极布伦特冰架一冰川发生断裂——面积约为1270平方公里
南极布伦特 冰架 冰川断裂 1270平方公里
2021/3/2
当地时间2021年2月26日，一块面积约为1270平方公里的冰川从南极洲布伦特冰架上分离出来。布伦特冰架上有英国的哈雷勘测基地，不过由于疫情和气候，该基地目前并没有工作人员。阿根廷南极研究所的科研人员表示，由于冰架需要保持平衡，冰川断裂是正常的自然现象。而且经过常年的观察研究，布伦特冰架上的冰川分离现象并未受到气候变化的显著影响。阿根廷科研人员将会密切观察冰川位置的变化，以便为下一个科考期规划航行...

生态系统韧性或逼近极限——百年模型显示本世纪末湖泊热浪显著增加
生态系统 韧性 逼近极限 湖泊热浪
2021/1/29
英国《自然》杂志近日发表的一项气候科学模型研究显示，到21世纪末，湖泊热浪（湖面水温极热的时期）的强度和持续时间将增加。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，伴随而来的，是生态系统的韧性可能逼近极限。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，人们在关于湖泊热浪及其如何受到全球变暖的影响方面，仍存在认知空白。湖泊生态系统对...
