野火可能会减缓臭氧层恢复

一项新研究表明，随着全球变暖，日益频发的野火可能会减缓臭氧层的恢复。

 

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 ozone¹ in the layer that protects the Earth from damaging ultraviolet rays.

这项研究发现，两年前的澳大利亚林火非常猛烈，以至于烟雾上升到了大气层，造成一系列复杂的化学反应，导致臭氧的损失，臭氧层是大气中保护地球免受紫外线破坏的气层。

 

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.

卫星观测表明，仅在2020年3月，南半球上空就一共损失了1%的臭氧。鉴于臭氧层几十年前受到破坏后，恢复缓慢，这一数字不容忽视。
