Return of a Cult Classic with a Twist; Now it's ARCTIC Ozone Holes!
Timothy Birdnow
Like a bad horror movie the Ozone Hole is making it's return; sort of a Son of the Grand Nephew of the Butler of Dracula, sans cape and dripping fangs! And who should be leading the charge? The Bela Lugosi of Science, the master of the Macabre, the defender of Islamic values - NASA.

According to the article in Space Daily:
"A NASA-led study has documented an unprecedented depletion of Earth's protective ozone layer above the Arctic last winter and spring caused by an unusually prolonged period of extremely low temperatures in the stratosphere.
The study, published online Sunday, Oct. 2, in the journal Nature, finds the amount of ozone destroyed in the Arctic in 2011 was comparable to that seen in some years in the Antarctic, where an ozone "hole" has formed each spring since the mid-1980s. The stratospheric ozone layer, extending from about 10 to 20 miles (15 to 35 kilometers) above the surface, protects life on Earth from the sun's harmful ultraviolet rays.
[...]
To investigate the 2011 Arctic ozone loss, scientists from 19 institutions in nine countries (United States, Germany, The Netherlands, Canada, Russia, Finland, Denmark, Japan and Spain) analyzed a comprehensive set of measurements. These included daily global observations of trace gases and clouds from NASA's Aura and CALIPSO spacecraft; ozone measured by instrumented balloons; meteorological data and atmospheric models.
The scientists found that at some altitudes, the cold period in the Arctic lasted more than 30 days longer in 2011 than in any previously studied Arctic winter, leading to the unprecedented ozone loss. Further studies are needed to determine what factors caused the cold period to last so long.
"Day-to-day temperatures in the 2010-11 Arctic winter did not reach lower values than in previous cold Arctic winters," said lead author Gloria Manney of NASA's Jet Propulsion Laboratory in Pasadena, Calif., and the New Mexico Institute of Mining and Technology in Socorro.
"The difference from previous winters is that temperatures were low enough to produce ozone-destroying forms of chlorine for a much longer time. This implies that if winter Arctic stratospheric temperatures drop just slightly in the future, for example as a result of climate change, then severe Arctic ozone loss may occur more frequently."
The 2011 Arctic ozone loss occurred over an area considerably smaller than that of the Antarctic ozone holes. This is because the Arctic polar vortex, a persistent large-scale cyclone within which the ozone loss takes place, was about 40 percent smaller than a typical Antarctic vortex."
End excerpt.
So, now they want to claim Ozone loss at the North Pole, and blame it on cooling in the atmosphere caused by, drumroll please, Global WARMING!
So warming leads to cooling which leads to an ozone hole! You can't make this stuff up!
Climatologist Timothy Ball debunks this assinine study from Nature in a post at his website.

I warned everyone that they would spin AGW into a new hysteria. They didn't let any grass grow under their feet. Thermogeddon has failed to materialize, as has ocean acidification, sea level rise, or any of the other popular scare tactics. They've had to bring back an old '70's cult classic.
