摘要
研究人员称,亚马孙雨林正走向一个“临界点”,一旦超过这个临界点,树木将开始大量死亡。英国埃克塞特大学、德国波茨坦气候影响研究所(PIK)和慕尼黑工业大学的学者合作,利用1991年至2016年的卫星数据来研究森林砍伐的趋势,并最终将成果发表在《自然气候变化》杂志上。据研究人员计算,75%的雨林在遭遇干旱时面临无法恢复的风险,而由于全球变暖,干旱现象越来越普遍。
The Amazon rainforest is moving toward a "tipping point"past which trees will start to die off in large numbers,researchers have said.The study,published in the journal of Natural Climate Change,was conducted by scholars from the University of Exeter,the Potsdam Institute for Climate Impact Reacarch(PIK)and the Tcchnical University of Munich.They used satellite data from 1991 to 2016 to examine trends in deforestation.They calculated that 75 percent of the rainforest is now at the risk of being unable to recover when experiencing droughts,which are also increasingly more common due to global warming.
