(ORDO NEWS) — Every year, an ozone hole appears over the Earth’s South Pole. In 2021, it increased in just a week to a size that even exceeds the territory of Antarctica.
Reported by New Scientist.
At the South Pole, spring begins in August-September. At this time, the ozone layer over Antarctica becomes much thinner, which leads to an increase in the ozone hole. This year it has increased so much that it exceeded all indicators since 1979. Experts have not yet been able to figure out the reason for what is happening.
Last year, the hole reached its maximum size around the beginning of October. In 2021, everything started as usual, and then in just a week, the growth of the ozone hole accelerated sharply.
The Copernicus Atmosphere Monitoring Service (CAMS) is closely monitoring the changes taking place in this region.
For this, not only highly efficient equipment and computer modeling are used, but also information obtained with the help of satellites. Vincent-Henri Poy noted that the hole will continue to widen until mid-October.
The ozone layer protects our planet from harmful ultraviolet radiation. In recent years, it has become much smaller due to the influence of various types of harmful substances, especially chlorofluorocarbons. Its recovery began after the ban of these substances, but it is happening too slowly and can take a lot of time.
