Description

The depletion of the ozone is a real thing. Twenty years ago scientists realized that the ozone layer over Antarctica grew thinner during the winter and spring. This thinning became known as the ozone hole. It resulted from chemicals called chlorofluorocarbons (CFCs) used in aerosol spray cans and refrigerators. In the stratosphere, oxygen atoms are constantly changing from ozone (three atoms) to oxygen gas (two atoms) and atomic oxygen (one atom) and back. By the 1970s, enough CFCs had reached the stratosphere to disrupt the ozone/oxygen balance. The ozone hole appeared over Antarctica, because cold air creates clouds of ice crystals that accelerate ozone loss. The production of CFCs was phased out around the world starting in 1995. The ozone hole has stopped growing, but it’s not expected to close completely for another 40 or 50 years at best. The depletion of the ozone is a real thing. Here's the scientific evidence to prove it. https://www.epaalumni.org/userdata/pdf/60740780F5ACB3D5.pdf#page=1
