THE large hole in the ozone layer above Antarctica has grown so big it's about the same size as the continent.

南极洲上空的臭氧层缺口近年来已经变得非常巨大,其缺口尺寸竟然几乎和南极洲一样大了。

The hole reached one of its greatest and deepest recored sizes this year and a video released by the European Space Agency has revealed its magnitude.

这个臭氧空洞是今年记录的最大、最深的洞之一,欧洲航天局发布的一段视频清楚地展示了它的尺寸。

欧洲航天局发布的资料显示,南极洲上空的臭氧空洞在2020年达到了顶峰。



"A detailed analyses from the German Aerospace Center indicates that the hole has now reached its maximum size."

“来自德国航空航天中心的详细分析表明,这个洞现在已经达到了最大尺寸。”

The ozone layer is an important layer surrounding Earth that shield's us from the Sun's ultraviolet radiation.

臭氧层是地球周围保护我们人类不受太阳紫外线辐射的重要屏障。

Ozone itself is actually a molecule that is floating in the atmosphere and is grouped together in the layer.

臭氧本身实际上是一种漂浮在大气中的分子,分子全部聚集在地球表面就形成了臭氧层。


The peak size of the ozone hole in 2020 is strikingly different from last year when the peak size of the hole was actually the smallest since records began.

2020年观察到的臭氧空洞的峰值大小与去年明显不同,去年臭氧空洞的峰值实际上是有记录以来最小的。

Vincent-Henri Peuch, Director of Copernicus Atmosphere Monitoring Service at ECMWF, said: "There is much variability in how far ozone hole events develop each year.”

欧洲中期天气预报中心哥白尼大气监测服务主任文森特-亨利·佩奇说:“臭氧空洞每年发展的程度都有很大的变化。”

"The 2020 ozone hole resembles the one from 2018, which also was a quite large hole, and is definitely in the upper part of the pack of the last 15 years or so.

“2018年的臭氧空洞也相当大,而且绝对是过去15年左右臭氧空洞的顶峰之一,而2020年的臭氧空洞与2018年的很相似。”

"With the sunlight returning to the South Pole in the last weeks, we saw continued ozone depletion over the area. ”

“过去的几个周里,随着太阳照射南半球,阳光返回南极,我们看到该地区的臭氧持续损耗。”



2020's peak size was recorded at 25 million square kilometres (about 9.6 million square miles) on October 2.

2020年10月2日,臭氧空洞达到一个高峰,其面积达到了2500万平方公里(约960万平方英里)。

The Montreal Protocol is an international treaty that was put in place in 1989 that aimed to phase out harmful manmade ozone destroying chemicals that could be found in things like refrigerators and sprays.

《蒙特利尔议定书》是一项于1989年生效的国际条约,它旨在逐步淘汰有害的人造臭氧化学物质,这些化学物质可能存在于冰箱和喷雾器中。


The largest hole size recorded was actually 29.9 million square kilometre back in 2000.

记录显示,最大的臭氧空洞出现在2000年,其面积大达2990万平方公里。

Strong polar winds and unusually stratospheric temperatures have thought to have been a set back for ozone hole progress this year.

科学教们认为强烈的极地风和不寻常的平流层温度对今年臭氧空洞的自我修复进展造成了阻碍。

Climate change explained

气候变化的解释

Here are the basic facts...

以下是一些基本事实……

Scientists have lots of evidence to show that the Earth’s climate is rapidly changing due to human activity

科学家有大量证据表明,正是由于人类活动,地球的气候正在迅速变化。

Climate change will result in problems like global warming, greater risk of flooding, droughts and regular heatwaves

气候变化将导致诸如全球变暖、更频繁的洪水、干旱和经常性热浪风险等问题。


The Earth only needs to increase by a few degrees for it to spell disaster

地球只要再上升几度就会引发灾难。

The oceans are already warming, polar ice and glaciers are melting, sea levels are rising and we’re seeing more extreme weather events

海洋在变暖,极地冰和冰川在融化,海平面在上升,我们看到了更多的极端天气事件。

In 2015, almost all of the world's nations signed a deal called the Paris Agreement which set out ways in which they could tackle climate change and try to keep temperatures below 2C.

2015年,世界上几乎所有国家都签署了一项名为《巴黎协议》的协议,该协议制定了应对气候变化、努力将气温控制在2摄氏度以下的方法。

In other news, the past decade has seen the Atlantic Ocean see its hottest temperatures in almost three thousand years.

其他方面,在过去十年中,大西洋出现了近三千年来的最高温度。

An unprecedented 'mega-tsunami' could be caused by a melting Alaska glacier, scientists have warned.
