A newly published report by the United Nations, the European Union, and NASA predicts the upper ozone layer above the Northern Hemisphere to be fully recovered by 2030 and the hole in the ozone layer above the South Pole to be completely disappeared by the year 2060.
Last century, news about a hole in the ozone layer shocked the world in the early 1980s. Following this global environmental problem, the Montreal Protocol was introduced. Most countries banned the use of CFCs, which is believed to be the cause of the hole in the ozone layer. The ozone layer protects the earth against UV radiation; this radiation could cause skin cancer. Today, better news is revealed! The ozone layer is showing signs of recovery.
Although most countries agreed to ban the use of CFCs, China continues to use the illegal gasses in their productions and ignoring the international agreement. This could lead to a slowdown in the recovery process of the ozone layer.
Since 2000, the ozone layer has been recovering by 1-3% every 10 years. This significant improvement means that the Northern Hemisphere should be intact by 2030. It will take another 30 years for the Southern Hemisphere to heal.
The head of the United Nations Environment announced that many countries agreed to reduce the use of HFCs as of 1 January 2019. These dangerous gasses cause global warming.
