Current events and future prospects of ozone depletion

Since the adoption and strengthening of the Montreal Protocol has led to reductions in the emissions of CFCs, atmospheric concentrations of the most significant compounds have been declining. These substances are being gradually removed from the atmosphere. By 2015, the Antarctic ozone hole would have reduced by only 1 million km² out of 25 (Newman et al., 2004); complete recovery of the Antarctic ozone layer will not occur until the year 2050 or later. Work has suggested that a detectable (and statistically significant) recovery will not occur until around 2024, with ozone levels recovering to 1980 levels by around 2068.

    臭氧稀薄化的現況和未來的展望

    自從採用而且加強蒙特利公約之後,已導致氟氯碳化物的排放減少,大氣層中最重要的混合物也一直下降。 這些物質正在逐漸地被從大氣層中移除。 在2015年 ,南極圈臭氧洞會從25百萬平方公里減少至只有一百萬平方公里 (紐曼等人, 2004) 在2050年或更晚,南極圈的臭氧層將完全恢復。研究顯示,可偵測到的恢復(統計上有效的)將不會發生,直到大約2024年,大約2068年臭氧層將恢復至與1980年一樣。
