Antarctic ozone hole declined


The NASA Space Agency this week announced that the ozone hole over Antarctica has shrunk, now being the smallest since 1988.

NASA has released this Friday that the ozone hole over Antarctica has shrunk to the smallest size since 1988 and has raised expectations that climate conditions will improve in that area and thus reduce some of the recorded and predicted problems.

The huge hole in the protective layer of ozone on planet Earth peaked in September, and NASA quantified its size by 19.6 million square kilometers.

And according to Paul Newman, a NASA scientist, stormy conditions in the upper atmosphere warmed the air and prevented chlorine and bromine from ‘eating’ ozone.

Newman said that this is good news and said that the downturn this year has natural causes, but that it is at the top of small but continuing improvements, most likely resulting from a treaty signed in 1987, which production and consumption of ozone-depleting chemicals.

Ozone is a combination of three oxygen atoms, and this important layer protects the Earth from ultraviolet rays that cause skin cancer, crop damage among many other problems.

NASA has clearly argued that shrinkage of the hole cannot be dissociated from the 1988 treaty, which was established during the Vienna Convention, which limited the consumption of chemical substances that destroy the protective layer, and underlines this as a determining factor.

Last year, NASA had counted, by this same time of year, an area of 23 million square kilometers in the hole of the ozone layer. A figure that, in the year 2015, was almost 30 million square kilometers.
