The Thinning Ozone Layer
The implementation of the aerosol-banning legislation has paid off asseveral scientists discover that the size of the hole (or rather the thinning region) in the ozone layer has stabilized. However, the scientists also warn about the several dangers that still remain.
According to a report made by the United Nations in 2006, the earth’s ozone layer was found to repel more harmful sun radiation as compared to the previous decades due to the increase in its thickness. In addition to UN’s repot, the atmospheric levels of several ozone-depleting chemicals were also found to have decreased since the late 1990s.
However, another region of the ozone layer over the North Pole was found to have thinned. Experts estimate the thinning to go on for the next 15 years due to a certain weather phenomena they are currently studying. Due to the complexity of the weather phenomena affecting the ozone layer, repairing the damaged region of the layer over the South Pole may take longer than expected. Scientists estimate the repair to be finished around the years 2060 and 2075.
Apart from the huge amount of time needed to repair the damage, scientists are also faced with another challenge. According to a study conducted by the Scientific Committee on Antarctic Research, sealing the ozone hole can speed up the melting of the region’s ice caps.
