A little ray of light in a dark world – the hole in the ozone layer is getting smaller due to the measures we are all taking to cut down and out on CFCs . But it won’t be at safer 1960s level until about 2050, so we all need to keep up the good work.
Finally some good news regarding the health of our planet: The hole in the ozone layer over Antarctica appears to have shrunk.
According to the European Space Agency’s MetOp weather satellite, the ozone hole’s size is at a record low. Per the satellite’s data from 2012, hole was the smallest it has been in the last decade.

LiveScience notes that the hole over Antarctica first appeared in the early 1980s and resulted from the use of chlorofluorocarbons (CFCs) and other ozone-depleting chemicals. It typically occurs from September through November, as a result of high winds, which channel cold air across the continent. Ozone-depleting chemicals are most damaging in cold weather.
In 2012, “It happened to be a bit warmer… in the atmosphere above Antarctica, and that meant we didn’t see quite as much ozone depletion as we saw [in 2011]…
