"It's Summer and we're runnin' out a' ice." So they sang in the musical "Oklahoma." Perhaps there will be a musical "Antarctica."
A-a-a-a-ntarctica, where the wind comes biting off the ice;
And the frozen ills and associated Chills and
Breaking Icicles off your nose is not Nice!
Professor Chris Turney is a leader of the Australian Antarctic Expedition 2013-14.
He is an Australian Research Council (ARC) Laureate Fellow and Professor of Climate Change at the University of New South Wales. Working in both the Antarctic and Arctic, Chris is extending historic records of change in the polar regions back to 130,000 years ago to help better understand the future.
The scale of Antarctica and the Southern Ocean is staggering. Over 98% of the continent is submerged by three large ice sheets that drown the underlying topography. The Australasian sector is dominated by the East Antarctic Ice Sheet, the largest of three ice sheets that contains enough freshwater to raise the world’s sea level by some 52 metres. Until recently it was thought this ice sheet was stable, sitting on the continental crust above today’s sea level. However there is an increasing body of evidence, including by the AAE members, that have identified parts of the East Antarctic which are highly susceptible to melting and collapse from ocean warming.Chris Turney, “climate scientist” has “set up a carbon refining company called Carbonscape which has developed technology to fix carbon from the atmosphere and make a host of green bi-products, helping reduce greenhouse gas levels.” (link)
NOT A LOT OF PEOPLE KNOW THAT According to Chris Turney, leader of the expedition trapped in the ice off the coast of Antarctica, the expanding sea ice has been caused by global warming.
He obviously has not bothered checking the facts. (See LINK)

Oh, if only Nature were listening, perhaps they wouldn't be trapped in ice.

|View from the bridge: Aurora Australis|
Nicky Phillips, Science Editor of the Sydney Morning Herald is aboard the Aurora Australis:
At its thickest, multi-year ice can reach about 3.5 metres in depth.
We're about to give some of the pack "a bash and see how it goes", says Aurora captain Murray Doyle.
The temperature is about minus 1.6 degrees, but the wind is about 30 knots so the wind chill makes it feel a fair bit colder.
A small crowd of passengers has started to gather on the bridge. After five days sailing, everyone is keen to see some serious ice-breaking.
Grant Hose, a scientist on board the Aurora, set his alarm for 6am.
"I wanted to watch us begin to break through the ice," he said. "There's an air of excitment on the bridge. But we are moving pretty slowly so it could be a long day."
While the ice cakes - flat pieces of ice less than 20 metres across - and ice floes - ice more than 20 metres across - are tightly packed, so far we've been able to navigate around them without too much trouble.The Australis could sing:
"It's summer and we're running into ice."UPDATE: TOO MUCH ICE (from Nicky Phillips)
“The ice became too thick for us to penetrate. Some of the floes are up to two metres of ice with a metre of snow on top and very compact.
“There was just nowhere for us to go."
