The hole in the ozone layer over Antarctica is nearing record-breaking size again, scientists say. In fact, new observations show that the infamous "ozone hole" is currently larger than the entire continent of North America.
Researchers at the German Aerospace Center are using Earth-observing satellites to monitor the protective ozone layer and recently reported that a large, nearly circular hole over Antarctica extends over an area measuring 26 million square km (10 million square miles).
Losing part of the ozone layer over Antarctica is an annual phenomenon, but for the past nine years, the ozone hole has been consistently smaller than the record-breaking 27 -million-square-km (10.4 million square miles) ozone hole measured in 2006, according to annual records from NASA's Goddard Space Flight Center. Scientists thought the apparent stabilization indicated that the ozone layer was recovering very gradually. But this year's ozone hole surprised them because it formed a whole month later in the year than the ozone hole typically forms, and its size is almost record-breaking.
The ozone layer protects life on Earth from the sun's harmful ultraviolet rays, according to NASA's Earth Observatory. Overexposure to ultraviolet rays increases the risk of skin cancer and cataracts in humans, and this type of radiation has also been known to cause blindness in animals, according to the Climate Science Coalition.
What says ATS?
Have the global ice age....no, wait.... global warming.... no, wait.... climate change... yeah, that's it... Have the Climate Change Alarmists finally run out of ideas to try and spread panic among the populace while unwittingly making their masters even more rich that we have come full circle and are "recycling" old panics???
The memo, by the leading Republican consultant Frank Luntz, concedes the party has "lost the environmental communications battle" and urges its politicians to encourage the public in the view that there is no scientific consensus on the dangers of greenhouse gases.
"The scientific debate is closing [against us] but not yet closed. There is still a window of opportunity to challenge the science," Mr Luntz writes in the memo, obtained by the Environmental Working Group, a Washington-based campaigning organisation.
"Voters believe that there is no consensus about global warming within the scientific community. Should the public come to believe that the scientific issues are settled, their views about global warming will change accordingly.
"Therefore, you need to continue to make the lack of scientific certainty a primary issue in the debate."
The phrase "global warming" should be abandoned in favour of "climate change", Mr Luntz says, and the party should describe its policies as "conservationist" instead of "environmentalist", because "most people" think environmentalists are "extremists" who indulge in "some pretty bizarre behaviour... that turns off many voters".
It was the Bush Administration under the advisement of Frank Luntz who started using climate change in place of global warming.

Well, it's something that would probably happen anyway but I believe that man is accelerating his own demise.

Aren't the glaciers actually gaining ice now? Something I heard on the radio the other day said it was.
Zwally said that while other scientists have assumed that the gains in elevation seen in East Antarctica are due to recent increases in snow accumulation, his team used meteorological data beginning in 1979 to show that the snowfall in East Antarctica actually decreased by 11 billion tons per year during both the ERS and ICESat periods. They also used information on snow accumulation for tens of thousands of years, derived by other scientists from ice cores, to conclude that East Antarctica has been thickening for a very long time.
Zwally's team calculated that the mass gain from the thickening of East Antarctica remained steady from 1992 to 2008 at 200 billion tons per year, while the ice losses from the coastal regions of West Antarctica and the Antarctic Peninsula increased by 65 billion tons per year.
"The good news is that Antarctica is not currently contributing to sea level rise, but is taking 0.23 millimeters per year away," Zwally said. "But this is also bad news. If the 0.27 millimeters per year of sea level rise attributed to Antarctica in the IPCC report is not really coming from Antarctica, there must be some other contribution to sea level rise that is not accounted for."

The ozone only protects us against galactic rays from the sun. Guess what? There's no one living on Antarctica. Open that hole up and fire away!
