美科学家预测全球气候环境将在2100年之前崩溃

2017-09-21 14:37:20   中国网

据俄罗斯“Lenta”新闻网援引英国《每日邮报》9月18日报道,美国科学家们近期在《美国科学院院报》上刊登报告称,全球气候环境将在2100年之前崩溃。

报道称,科学家们对气温上升导致地球居住条件恶化程度进行了评估,并总结出3种环境崩溃情景。在第一种“危险”情景中,全球年平均气温的增幅不超过3℃。届时飓风、洪水和干旱天气的出现次数将会更加频繁。第二种“灾难性”情景的发生概率为5%,该情境中年平均气温的增幅在3℃至5℃,届时西南极洲的冰盖完全融化,亚马逊雨林也将彻底消失。在第三种“超级灾难性”情境中,年平均气温增幅将超过5℃。科学家们没有对该情况的发展态势作系统评估。众所周知,在这样的“超级灾难性”情景中,人类将面临包括淡水资源在内的基本生存资源严重短缺。

报道补充道,在近200年来,人类日常生活过程中产生的碳排放量超过6000亿吨,这导致整个大气层中的二氧化碳的含量增加了0.012%,而全球平均气温也增高了1℃(陆地气温增加了1.5℃)。(杨桥)
