Sept. 2014 all time record Antarctic Sea Ice, third year in a row in satellite era of record Antarctic Ice-Australian Broadcasting Corp.

9/17/14, "Extent of Antarctic sea ice reaches record levels, scientists say," abc.net.au, Jane Ryan and Sam Ikin


Satellite imagery reveals an area of about 20 million square kilometres covered by sea ice around the Antarctic continent.

Jan Lieser from the Antarctic Climate and Ecosystems Cooperative Research Centre (CRC) said the discovery was made two days ago.

"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 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 polynia  - areas of the ocean surface where currents and wind patterns combine to generate sea ice.

"As soon as sea ice is produced in these polynias it is actually transported away from that so more sea ice can be produced," Dr Lieser said.

As the area covered in sea ice expands scientists have said the ice on the continent of Antarctica which is not over the ocean continues to deplete. 

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. 

He said changes to sea ice levels could have implications for the entire Antarctic ecosystem.

"So the sea ice is a very important habitat for krill in particular and for the reproduction of krill and that forms one of the absolute staples of the diet for many species in the Antarctic."

While the Antarctic ecosystem braces for change, the world's Antarctic research vessels will also have to contend with treacherous conditions in the months ahead."

*Added: There has been no increase in global temperatures and therefore no "warming atmosphere" for at least 15 years. Lack of warming may continue for at least another decade.

$1 billion a day was spent on non-existent man caused global warming in 2012 alone.

8/21/14, "Global warming slowdown 'could last another decade'," BBC, Matt McGrath

"Scientists have struggled to explain the so-called pause that began in 1999, despite ever increasing levels of CO2 in the atmosphere.

The latest theory says that a naturally occurring 30-year cycle in the Atlantic Ocean is behind the slowdown....

The world's overall temperatures haven't risen beyond the record set in 1998....[subhead, 'Ice age fears']
