Studies of the state of the environment in recent years testify to one thing: our civilization is steadily moving toward environmental catastrophe. And yet, in a recent UN report, despite the continuation of this trend, there are some positive developments. This includes, in particular, the results of global efforts to restore the ozone layer, which protects our planet from harmful ultraviolet radiation.

Every four years, an international team of researchers prepares a report on the state of the ozone layer of the Earth. Unfortunately, for decades, under the influence of millions of tons of chlorofluorocarbons (CFCs) emitted into the atmosphere, it has been depleting at an alarming rate, which inevitably threatened our planet with catastrophic consequences.

Everything changed in September 1987, when the international Montreal Protocol was signed, which entered into force in early 1989 and ratified by 196 states. His main idea is to stop using chlorofluorocarbons, the release of which has been completely banned since 2010.

The first positive results were noted already in 2000. During the first decade, the ozone content in the atmosphere increased by 1–3%. Based on current forecasts, the ozone layer will fully recover over the northern hemisphere of the Earth by 2030, over the southern – by 2050, and over the polar regions – by 2060.

However, not all problems are solved. A lot of claims from environmentalists to China. A supplement to the Montreal Protocol – the Kigali Amendment, which will prohibit the use of hydrofluorocarbons, is currently under development. If it is approved, the process of global warming, according to experts, will be able to slow down by 0.4%.
