Massive Hole in Arctic Ozone Layer

Sustainability Ninja

A recent study released by NASA has shown a massive loss of the protective ozone layer above the Arctic last winter and spring. The loss of the ozone in that region is caused by an unusually prolonged period of extremely low temperatures in the stratosphere. The study, published online today in the journal Nature, discovered that the loss of ozone in the Arctic this year was comparable to the one in the Antarctic. Eco News arctic ozone loss

Now comes news from the World Meteorological Organisation (WMO) that the depletion of the ozone layer has reached what the WMO describes as an “unprecedented level” between December 2010 to March 2011, thanks to the ongoing presence of ozone-depleting substances in the atmosphere.

I have been saying for years (and I am no scientist), ever since the “discovery” of this hole in the ozone layer that it may have always been there and that it may be a kind of safety valve for Planet Earth. But the scientific community not even considered that possibility and immediately claimed that CFCs were responsible for this hole and that this might be the beginning of the ozone layer being destroyed entirely by those gases.

Arctic Ozone Hole’s Effect on Food Supplies this Winter

Green Blog

One of the biggest indicators of climate change are ozone holes, zones where the ozone that forms the protective layer of Earth’s atmosphere are too thin to be protective anymore. The reactions that convert less reactive chemicals into ozone-destroying ones take place in the polar vortex. The journal nature has confirmed that conditions this year have created the ozone hole in the North Pole. This creates reactions that are the cause of ozone breakdown.

Arctic Ozone Hole Biggest on Record


A huge hole that appeared in the Earth's protective ozone layer above the Arctic in 2011 was the largest recorded in the Northern Hemisphere, scientists have reported. The ozone layer acts a kind of shield against UV radiation and helps in protection against skin cancer. Since the 1980s, everyone in the Southern Hemisphere has been aware of the hole in the ozone every summer above Antarctica.
