Extremely warm stratospheric air temperatures are forcing their way over the South Pole and weakening the Antarctic Polar Vortex. This type of event is called Sudden Stratospheric Warming, or SSW, and is… Read More

Recipe for an Ozone Hole

The annual formation of the Antarctic Ozone Hole is a dynamic process combining extreme environmental factors with manmade chemicals to destroy the ozone layer in an incredible display of catalytic destruction. While destructive chlorine damages the Ozone Layer globally, the danger is most apparent during the annual formation of the Antarctic Ozone Hole. Before the… Read More

The Antarctic Ozone Hole

The Ozone Layer is the name given to large concentrations of naturally occurring ozone located high in the stratosphere between 35,000 – 160,000 feet. The ozone layer is important to life on Earth because of its ability to filter out harmful doses of ultraviolet radiation from the Sun that damage DNA in plants and animals… Read More
