利好消息! 臭氧層破洞正緩慢恢復!

The ozone layer that shields life from cancer-causing solar rays is recovering at a rate of 1-3% per decade, reversing years of dangerous depletion caused by the release of harmful chemicals, a UN study said on Monday.

聯合國本週一公佈的一項研究稱，爲生物阻擋可致癌的太陽輻射的臭氧層正以每10年1%-3%的速度恢復，扭轉多年來因排放有害化學物導致的臭氧層危險損耗的局面。

The four-yearly review of the Montreal Protocol found long-term decreases in the atmospheric abundance of controlled ozone-depleting substances and the ongoing recovery of stratospheric ozone.

每四年進行一次的《蒙特利爾議定書》評議發現，大氣中受控臭氧損耗物質的總量呈長期下降趨勢，平流層臭氧持續恢復。

The Antarctic ozone hole was expected to gradually close, returning to 1980 levels in the 2060s, the report said.

評議報告指出，南極臭氧破洞有望逐步閉合，到本世紀60年代恢復至1980年的程度。

"The Antarctic ozone hole is recovering, while continuing to occur every year. As a result of the Montreal Protocol much more severe ozone depletion in the polar regions has been avoided," the report said.

該報告稱：“南極臭氧洞正在恢復，而且每年的恢復都在進行中。正是由於《蒙特利爾議定書》，極地地區更嚴重的臭氧消耗已被避免。”

"Evidence presented by the authors shows that the ozone layer in parts of the stratosphere has recovered at a rate of 1-3% per decade since 2000," UN Environment and the World Meteorological Organization said in a statement.

聯合國環境規劃署和世界氣象組織發表一則聲明稱：“報告作者提出的證據顯示，自2000年以來，部分平流層中的臭氧層以每10年1%-3%的速度恢復。”

"At projected rates, Northern Hemisphere and mid-latitude ozone is scheduled to heal completely by the 2030s followed by the Southern Hemisphere in the 2050s and polar regions by 2060."

“按預估的速度計算，北半球和中緯度地區的臭氧預計將在本世紀30年代完全修復，隨後是南半球在50年代修復，極地地區在2060年前修復。”
