article imageHole in ozone layer causes Earth to experience cooling

By Andrew Moran     Dec 6, 2009 in Environment
A group of British scientists from the British Antarctic Survey have discovered this week that the ozone layer hole is cooling down the Earth and protecting Antarctica from melting.
Climategate has been the hot topic of environmental news over the last several weeks. The news that a group of scientists that contributed to the United Nations Intergovernmental Panel on Climate Change has made many wary about the integrity of the real data and information on manmade global warming and climate change.
Next week, leaders from around the world will gather in Copenhagen, Denmark at the Climate Summit to discuss actions necessary to address global warming. One of the main ideas is a carbon tax and a cap-and-trade system.
A group of scientists in the United Kingdom are claiming that the hole in the ozone layer is protecting the Earth from global warming and which may be protecting parts of Antarctica, according to Russia Today.
The Scotsman notes that the ozone layer takes in heat from the sun, which hurts the atmosphere. When the ozone is absent, it creates a cooling effect. The scientists say that Antarctica is actually cooling and continued that path for the last fifty years, which will add to the debate in Copenhagen on Monday.
Climate forecaster Piers Corbyn states, “The facts about Antarctica are that it’s been cooling for about fifty years. New ice breaking off is evidence of nothing whatsoever – except new ice always breaks off.”
Since 1980, there has been a 10 per cent increase in sea ice in Antarctica, according to the British Antarctic Survey, but one of their most interesting findings is that the hole in the ozone is protecting the icy continent from global warming.
For the last decade, scientists predicted that the hole in the ozone was going to emit dangerous amounts of radiation that will create skin cancers in astronomical amounts.
The BAS further adds that the ozone hole has cooled the stratosphere, which strengthens cyclonic winds. This leads to the creation of more open water and then more sea ice forming. Winds over the Southern Ocean that surrounds Antarctica has actually increased 15 per cent.
John Turner from the BAS says, “One of the big mysteries for us was why we are seeing a warming over the Arctic but at the same time we’re seeing a cooling over the Antarctic. So what we think has happened is that the ozone hole has shielded us from the impacts of global warming.”
But BAS concludes that it will not last forever and that the hole will heal in the next 60 years, which, by then, the melting ice in Antarctica will have contributed a 1.5 meter rise in sea levels. The scientists are forecasting a three degree increase over the century, which means a third of the ice will have been lost. However, the main ice sheet will not have been melted.
This latest news has prompted many people across the globe to question everything that has happened throughout the scientific community. The Guardian’s Janet Daley pegs the question, “if the experts who gave us melodramatic warnings about the terrors of the damaged ozone layer got it so spectacularly wrong, why should we trust their equally alarming predictions about the dangers of its disappearance?”
