Hole in the ozone layer now its started healing

This year’s maximum ozone hole level is around 10 million square kilometers, less than half the size of the ozone hole that has usually been achieved in the last few decades. said the researcher

This makes it one of the smallest ozone holes in the 80s. Our ozone CAMS estimates that the ozone hole will be closed within a week.

Large fluctuations in the polar vortex and temperature in the stratosphere cause ozone holes of different sizes.

This year, the warmer polar stratosphere has delayed wind fields around the South Pole or Polar vortex and reduced the formation of polar stratospheric clouds that allow chemicals to quickly deplete ozone.

High in the stratosphere, ozone protects us from harmful UV radiation associated with skin cancer, cataracts, and other environmental problems.

In 80s, widespread use of dangerous chlorofluorocarbons in products such as refrigerators and aerosols damaged the ozone atmosphere and caused holes in the ozone layer above Antarctica.

Recovery of the zone hole will continue in the coming years. In 2018, it has recovered at a rate of 1-3% per decade since 2000.

At this projected level, northern hemisphere ozone and average latitude will recover by 2030, followed by the southern hemisphere around 2050 and the polar region by 2060 researcher said.
