These agreements are hailed as great successes, and annual reports summarizing official statistics are published showing that the use of CFC continues to decrease. The content of chlorine (from decay of CFC’s) in the stratosphere has leveled off, and two years ago the ozone hole over the Antarctic was the smallest in decades (and broken up into two).
这些协议被誉为伟大的成功，公之于众的年度报告总结了官方数据并显示CFC的使用数量正在下降。平流层的氯气含量（来自CFC’s的变质）已经稳定，两年前出现在南极上空的臭氧洞是数十年来最小的（并且已经分裂成两个）。然而，新的报告显示南极上空的臭氧层正越来越稀薄，并且去年南极上空的臭氧洞与以前一样大一样深。
