sea ice blocking Mawson … may have to move

A media shock! Two sides to the story! Only one is believable, as there has been no warming for 20 years, you can decide. Antarctica is at record sea ice extent, after increasing steadily for the last few decades.

That good ol’ Antarctic peninsula again

These guys below are remarkably incurious.  They see the sudden change in parts of the Antarctic peninsula but are sure they have a magic decoder ring that tells then what causes the change — global warming, of course.  But how come the change is so sudden and so recent?  And how come it has happened during a period when there has been NO global warming?  Their explanations linking it to global warming are obviously just desperate stabs in the dark

And the real cause is known anyhow.  There have been several recent reports of subsurface vulcanism in the Western margin and the peninsula.  Having a volcano underneath an ice mass is a pretty good way of melting some ice.  And volcanoes are sudden and episodic.  So  vulcanism explains what the Warmists could not — the SUDDEN onset of the melting.  And the second aspect of volcanoes — that they are episodic — shows how absurd are the great extrapolations offered below.  Volcanoes are mostly caused by tectonic shifts so most erupt and then stop as the plates re-adjust. You cannot reasonably project vulcanism into the future, let alone the distant future.  It could stop tomorrow. So the alarming predictions below are just the usual sort of baseless scare that we expect from Greenies

The article below is from the Daily Mail and they obviously didn’t like the Warmist claims either.  They followed the original story with a quote from a polar expert which pointed out a hole in the story and added a “box” to the article (the words from the capital letters onward) which also shows the absurdity of saying that the Antarctic is being affected by global warming:

Growing sea ice surrounding Antarctica could prompt scientists to consider relocating research stations on the continent, according to the operations manager of the Australian Antarctic Division.

Rob Wooding said that resupplying Australia’s Mawson Station – the longest continuously operated outpost in Antarctica – relied on access to a bay, a task increasingly complicated by sea ice blocking the way.

He said that at Mawson, the ice typically breaks up for one or two months of the summer, but in the last four to six years this has not happened every year and some years only partially.

He said: ‘We are noticing that the sea ice situation is becoming more difficult.

‘In the 2013-4 season we couldn’t get anywhere near Mawson due to the sea ice and we had to get fuel in there by helicopter which is inadequate for the long-term sustainability of the station.’

He said that French and Japanese bases on the continent have had similar problems.

Tony Worby, from an Australian centre studying Antarctic climate and ecosystems, said that in contrast to the Arctic where global warming is causing ice to melt and glaciers to shrink, sea ice around Antarctica was increasing.

It hit a new record in September last year, with the US-based National Snow and Ice Data Center reporting that the ice averaged 20.0 million square kilometres (7.72 million square miles) during the month.

Scientists have struggled to predict sea ice conditions, which are believed to be affected by the strong winds of the Southern Ocean which can push the ice out from the continent of Antarctica.

This does not happen in the Arctic because the ocean is hemmed in by land masses.

The Antarctic ice sheet in a previously stable part of the frozen continent is thinning at a rate that has added more than 300 trillion litres of water to the surrounding ocean in the past six years.

Scientists have expressed alarm at the rate of ice loss at the Southern Antarctic Peninsula, which had shown no signs of change until 2009, when it started suffering rapid destabilisation.

Now new research has revealed that glaciers along the peninsula have been melting at accelerating rates, causing the mass of ice there to reduce.

The loss of ice in the region is so large that it has caused the gravitation field of the Earth to change, according to some measurements conducted by scientists.

Since 2009, scientists estimate that the volume of water lost from the ice sheet is equivalent to a body of water larger than Lake Winnipeg in Manitoba, Canada or 350,000 Empire State Buildings.

Researchers warn that the melting glaciers are likely to drive rising sea levels if they continue to melt. […]
