野火可能會減緩臭氧層恢復(fù)

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。
