Global warming causes record Antarctic sea ice say "experts"
Antarctic sea ice is at the highest level since satellite records began causing much consternation among climate "scientists". Of course the announcement comes complete with the whacko theory that all this extra ice is caused by global warming. From the ABC news:
Antarctic scientists have declared a new record has been set for the extent of Antarctic sea ice since records began.
Satellite imagery reveals an area of about 20 million square kilometres covered by sea ice around the Antarctic continent.
"This is an area covered by sea ice which we've never seen from space before," he said.
"Thirty-five years ago the first satellites went up which were reliably telling us what area, two dimensional area, of sea ice was covered and we've never seen that before, that much area.
"That is roughly double the size of the Antarctic continent and about three times, four times the size of Australia."
The formation of sea ice around Antarctica every year is one of the biggest seasonal events on Earth.
The ice is generated in what scientists refer to as "sea ice factories" or polynias; areas of the ocean surface where currents and wind patterns combine to generate sea ice.
CEO of the Antarctic Climate and Ecosystems CRC, Tony Worby, said the warming atmosphere is leading to greater sea ice coverage by changing wind patterns.
"The extent of sea ice is driven by the winds around Antarctica, and we believe that they're increasing in strength and part of that is around the depletion of ozone," he said.
