Experts from the National Meteorological Administration of Japan, published data that the area of the ozone hole over Antarctica reached 23.4 million square kilometers.
According to Japanese meteorologists formation of the ozone hole occurs every year between August and December. One of the reasons for its occurrence, scientists call a high concentration in the atmosphere of a gas such as freon. Over the past two months, the size of that hole has exceeded 1.7 times the area of Antarctica itself.
In recent years, thanks to the efforts of international organizations, the content of Freon in
the atmosphere is significantly reduced. There is a tendency to reduce the size of the ozone hole, but unfortunately the pace of recovery of the protective layer are much slower than we would like. Will take decades until the ozone hole will be reduced to the size recorded in 1980.
