作为全球环境恶化的标志之一,南极上空的臭氧空洞已成为世界关注的共同话题,但现在有科学家通过观测发现,北极上空的臭氧含量也正在以每年1%～2%的速度在减少,目前,在北极大气层的中心区已出现了一个臭氧含量较低的中心区。这个中心区会不会发展成为像南极一样的臭氧层空洞?目前,科学家们正试图通过在北极冰盖下抽取远古时 As one of the signs of the deterioration of the global environment, the ozone hole over the Antarctic has become a common topic of concern in the world, but now scientists have observed that the ozone content over the Arctic is also decreasing at a rate of 1% to 2% per year. In the central area of ​​the Arctic atmosphere, there has been a central area with a lower ozone concentration. Will this central area develop into an ozone hole like the South Pole? At present, scientists are trying to extract ancient times under the Arctic ice cover.
