These ozone-destroying chemicals are used in aerosol sprays on Earth.

这种能够破坏臭氧层物质在地球上用于雾喷雾器。

The 1987 Montreal Protocol phased out the use of chlorofluorocarbons, or CFCs, responsible.

分阶段撤销氯碳物、氟氯碳物、以及其他一些会对臭氧层造成破坏物质使用。

Other aerosols can host chemical reactions that damage the ozone layer.

其他溶胶可以主导伤害臭氧层反应。

A second important area is monitoring the size of the hole in the ozone layer above Antarctica, since this is an indicator of global ultra-violet radiation levels.

第二个重要地方是检查南极洲上臭氧层洞大小，因为标志着全球紫外线辐射水平。

This means the size of the ozone hole changes year on year.

这意味着臭氧层洞大小每年都在改变。”

The ozone hole had been growing for decades over Antarctica.

几十年来，南极洲上臭氧层洞在不断扩大。

High up in the atmosphere, ultraviolet radiation transformed oxygen into ozone and gave Earth a vital shield — the ozone layer.

在大层高处，紫外线辐射将氧转为臭氧，为地球提供了一个至关重要屏障——臭氧层。

It's linked to global warming, acid rain, effects on wildlife, depletion of the ozone layer.

污染和全球变暖、酸雨、野生动物保护、臭氧层耗竭这些问题息息相关。

Right. So in this headline, it's saying that if nothing changes, if everything carries on the way that it is now, then the Earth's ozone layer — this protective shield — will have recovered by 2066.

没错。因此，在这个标题中，说是，如果什么都不改变，如果一切都照现在这样进行下去，那么地球臭氧层——这个保护层——将在 2066 年恢复。

A chemical that helped to create a hole in the ozone layer is reappearing.

一种导致臭氧层洞物质重新出现。

The ozone layer, our protection against the sun's UV rays, is made of oxygen.

氧组成臭氧层使人免受紫外线伤害。

These do not harm the ozone layer and are more energy efficient.

们不会损害臭氧层，而且更节能。

The study says it should fully recover within decades.

该研究称，臭氧层将在几十年内完全恢复。

It would be enough to totally destroy the Earth's ozone layer.

这足以彻底摧毁地球臭氧层。

The layer sits between 15 to 30 kilometers above Earth's surface.

臭氧层位于地球表面上方15至30公里处。

A new United Nations report says the Earth's ozone layer appears to be healing.

联合国一份新报告显示，地球臭氧层似乎正在愈合。

This pays great dividends for everyone as it also serves to protect the ozone layer.

这对每个人都有好处，因为还可以保护臭氧层。

Another way we are using float data is to help us to understand the mechanics of climate change, like global warming and ozone depletion.

另外，我们利用漂浮体数据帮助我们了解候变运行方式，比如全球变暖和臭氧层洞。

It goes up every morning at 11 o'clock and measures air temperature and the density of the ozone layer to an altitude of up to 30 kilometers.

每天早晨11点上升，并测量高达30公里温和臭氧层密度。

After all, nothing can fry us more and better than cosmic radiation and this will happen because the ozone layer will also disappear.

毕竟，没有什么比宇宙辐射更能把我们烤焦了，这将会发生，因为臭氧层也会消失。
