The ozone layer hole is expected to close in the next 50 years, according to the National Oceanic and Atmospheric Administration (NOAA) in the United States.

Scientists from NOAA found that, compared to the 1980s, concentrations of hazardous chemicals had decreased by just over 50% in the mid-level of the stratosphere, which they described as a “significant milestone” on the path to recovery.

According to NOAA, the Antarctic ozone layer, which shields all life on Earth from the sun’s dangerous radiation, may eventually recover “sometime around 2070.” Every year, during spring in the Southern Hemisphere, a massive hole starts to form as a result of intricate meteorological and chemical processes.
