Good news for those living in the southern hemisphere, the ozone hole may be shrinking

After reaching a record high in 2006, scientists at the European Space Agency (ESA) reports that the ozone hole decreased by nearly a third in 2007. The agency also warned that the decrease is not a sign of permanent recovery, based on their research.

Ozone (O3) is a compound found in Earth’s upper atmosphere. It is found in high concentrations in the titular ozone layer which is part of the stratosphere. The ozone layer provides the essential function of protecting the Earth from harmful ultraviolet (UV) radiation.
