The World Meteorological Organization (WMO) has announced that the Earth’s ozone layer is gradually recovering. Research indicates that in 2024, the overall ozone concentration in the stratosphere was higher than in previous years, and the ozone hole over Antarctica was less extensive. The maximum ozone deficit of 46.1 million tons was recorded on September 29. During that month, ozone depletion occurred slowly, followed by a relatively rapid recovery. Ozone loss remained below average until mid-November.

The ozone layer plays a crucial role in protecting the Earth from harmful ultraviolet radiation. In the 20th century, it suffered significant damage due to widespread industrial use of ozone-depleting substances (ODS). In 1987, the Montreal Protocol was signed to phase out 99% of these substances. By then, the ozone layer had already been severely damaged, resulting in a large ozone hole over Antarctica.

Thanks to the reduction of ODS, the ozone layer began to recover. Projections suggest that it will be restored at low latitudes by 2040, in the Arctic by 2045, and over Antarctica by 2066.

Scientists also evaluated the effects of global warming on ozone recovery. A side effect of climate change is a cooling of the ozone layer, which leads to increased formation of stratospheric clouds over Antarctica, potentially delaying the closure of the ozone hole.

Despite progress, experts stress the need for continuous monitoring of the ozone layer and strict control over the use of ozone-depleting substances.

Recently, it was reported that a new island has appeared in Alaska due to global warming. The rapid melting of the Alsek glacier has surrounded a land area with water, turning the region from an icy environment into a lake-rich landscape.
