The study found the Australian bushfires two years ago were so intense that smoke rose into the atmosphere, causing a complex set of chemical reactions that led to the loss of ozonein the layer that protects the Earth from damaging ultraviolet rays.
這項(xiàng)研究發(fā)現(xiàn),兩年前的澳大利亞林火非常猛烈,以至于煙霧上升到了大氣層,造成一系列復(fù)雜的化學(xué)反應(yīng),導(dǎo)致臭氧的損失,臭氧層是大氣中保護(hù)地球免受紫外線破壞的氣層。
Satellite observations suggest a total ozone loss of 1% over the southern hemisphere within the month of March 2020 alone. Not insignificant2, given the slow recovery of the ozone layer from damage caused decades ago.
衛(wèi)星觀測(cè)表明,僅在2020年3月,南半球上空就一共損失了1%的臭氧。鑒于臭氧層幾十年前受到破壞后,恢復(fù)緩慢,這一數(shù)字不容忽視。
