THE OZONE LAYER COULD BE COMPLETELY "CURED" FOR YEAR 2060
According to projected calculations, the southern hemisphere will recover in the 2050s and the polar regions by the year 2060The Montreal Protocol was an international agreement that regulated the use of substances that deplete the ozone layer. Recent studies show that there is a recovery, an important achievement. A good example of how we must face Climate Change.
In recent decades, humans have caused significant damage to the ozone layer, whose function is to protect the Earth from the ultraviolet rays of the sun. The implementation of global agreements such as the Montreal Protocol of 1987, has contributed to the solution of the problem.
The Scientific Assessment of Ozone Depletion study of 2018 is a series of reports that the United Nations Organization publishes every four years. For the year 2018, it showed a recovery of the ozone layer at a constant rate of 1 to 3% since 2000.
According to elaborated projections, the ozone of the northern hemisphere and medium latitude will recover completely by the 2030s.
Although it is an important achievement, there are many aspects to solve. For example, chlorofluorocarbon (CFC) emissions are increasing in China and in Latin American countries.
On October 15, 2016, the 197 countries that are part of the Montreal Protocol signed the Kigali amendment to progressively reduce the use of hydrofluorocarbons (HFCs) worldwide.
These agreements offer hope, especially when humanity faces the devastating effects of a 2 ° C rise in temperature compared to pre-industrial levels.
If the agreement is met, up to 0.4% of global warming can be avoided in this century, which means a major achievement in terms of climate change.
According to projected calculations, the southern hemisphere will recover in the 2050s and the polar regions by the year 2060.
