UN: Ozone layer recovery on track
联合国：臭氧层有望在40年内恢复
The Earth's ozone layer is expected to recover within 40 years and will be protected by the phasing out of nearly 99% of ozone-depleting substances, a UN-backed panel of experts said in a report Monday.
当地时间1月9日，一个由联合国支持的专家组发布报告表示臭氧层有望在40年内恢复，已经通过逐步淘汰近99%的消耗臭氧层物质，而得到了保护。
In a report published every four years on the progress of the Montreal Protocol, if current policies remain in place, the ozone layer is expected to recover to 1980 values by 2040.
《蒙特利尔议定书》科学评估小组每四年发布一次评估报告，本次报告称，如果当前的政策保持不变，预计臭氧层将在2040年恢复到1980年的水平。
Over the Antarctic, that recovery is expected by around 2066, and by 2045 over the Arctic.
在南极地区，预计到2066年左右恢复，而在北极地区则到2045年。
The Montreal Protocol was signed in September 1987, and it was designed to protect the ozone layer by phasing out "ozone-depleting substances".
《蒙特利尔议定书》于1987年9月签署，旨在通过逐步淘汰“消耗臭氧层的化学品”来保护地球臭氧层。
Chlorine levels are down 11.5% since they peaked in 1993, and bromine is at lower levels in the air, dropping 14.5 percent since its 1999 peak, the report said.
报告表示，其中氯的大气含量相比1993年的峰值下降了11.5%，溴在大气中的水平比较低，含量较1999年的峰值下降了14.5%。
The recovery of the ozone layer is expected to reduce the sun's harmful ultraviolet radiation to humans, preventing skin cancer and cataracts.
分析认为，臭氧层的恢复有望减少太阳有害紫外线对人类的辐射，避免因此导致的皮肤癌和白内障等疾病。
