Happens all the time on various scales...  Ice gets heavy and cracks...  not melts.

I hope it floats up to WA and cools them off

And when the ice shelves are gone the land based glaciers that reach sea level will be affected by the warmer waters that will be at the base of the glaciers. Lots more icebergs will be calved, float off and melt—and raise sea levels at an ever–faster rate.

It happened with Greenland and Greenland is now losing HUGE amounts of ice.

Don’t talk about what you know nothing about Boobhead. That includes climate.

You talking about all of Greenland or just the surface of the ice sheet??

Were you not cracking what you think are jokes about polar bears vacationing in the south, i.e. in that tight packed sea ice off Newfoundland that used to be on Greenland?

Being witty—you thought. The rest of us thought you were being halfwitty  You were just reminding us of the HUGE amount of ice Greenland had lost.

Been happening for years has it. Sort of confirms that 4000Gton figure then. 

Nope. You stuffed up again.

Thanks for the laugh 

Shouldn’t talk about yourself like that but for once something you post has the smell of truth about it.

You are being very defensive there Grendel

I never said it was anything to do with climate change.
This is an Environmental forum, I thought that this story was of environmental interest

Greenland used to have iceshelves like Antarctica does. The OMG program showed that once the ice shelves went the loss of ice from Greenland glaciers accelerated. Looks like this is starting to happen to Antarctica.


(OMG—Oceans Melting Greenland)

Yep - just saw it on the Antarctic FB page.
Massive 6,000 square kms.

I doubt it will float out beyond the Southern Gyre.

"Glacier flow and ice loss in an important region of Antarctica has increased only marginally in recent decades, a satellite study has found."

Where did you find that? Citation please.

That is what scientists working in this field were saying this morning on ABC News (formerly ABC24.)

Anybody with a brain would see that would happen. Larsen A & B are gone and the glaciers that formerly fed the shelf have accelerated now they are calving directly into the sea. The same thing happened with Greenland (Oceans Melting Greenland program.)

Just the application of common sense. Of course, rightwingers hate change and do not want to admit to reality but the situation is ice shelves are going, glaciers are accelerating and so the sea level is rising faster and faster.

Jovial Monk wrote on Jul 13^th, 2017 at 4:20pm:

Apparently the circulating current around Antarctica has tightened thus changing the atmospherics that intrude the Australian continent but that is all I know!

Hopefully the water hemisphere isn't changing too much or we are in big big trouble: so much that I would expect global panic by now!

The northern hemisphere will be the first port of call!

No need. It is the null hypothesis.

It appears Lees has no idea about any of this.

Natural variation can be safely discarded as it was not a serious theory, just an excuse for Lees not to accept AGW.

Dear Jovial, don't you know the answer to everything is UNDERSEA VOLCANOES and then smoking more meth from daddykins pocket/dismissed-as-a-dunce  money 

I think lees imagines he used to steal people's/ MAKE-THAT-EVERYBODYS -lunch money .... No seriously: that is my theory bro

Apart from the final, complete breakup of the LarsenC iceshelf attention now should be paid to the Thwaite glacier.

I will leave the mental pygmies here to search that for themselves. Some will need help 

No, I created it in Relationship, then Aussie locked it at my request.

I did that because this board is filled with bullshit and I wanted a few posts that would not be drowned in bullshit, deflection, obfuscation and so on.

You can discuss that post here.

So, go on, surprise me and write some high quality comments on that post.

Grendel wrote on Jul 13^th, 2017 at 11:32pm:

What would Grendel know 

That stuff about shelves cracking due to weight or earth movement is kind of ridiculous:

The Larsen A & B shelves broke up and didn’t re-form.

Larson C had actually LOST weight due to warm air and ocean!

Something is happening down there, something likely caused by AGW.

Next point of concern: Thwaites Glacier.

Probably the rest of the Larsen C will break up soon, leading to an uptick in glaciers calving there, adding to sea level rise.

Tell me Loser Lees, you looked up Thwaites Glacier yet? That will make Larsen A–C look like a damp squib!

All this obfuscation, and it has no point anymore does it? Apart from holding back that acceptance that AGW is real.

We have learned that the Larsen C iceshelf thinned by 4m from warm air and warm waters above and below.

The bit that broke off also included part of an anchor point holding the rest of the shelf in place. With the warming above and below, with the loss of a part of an anchor point I think the rest of the ice shelf will soon follow the bit that broke off. Then the glaciers that used to end at the ice shelf will end where the warmer waters are, accelerating the iceloss from the Antarctic peninsula.

However, the Peninsula is penny ante stuff. The Thwaites Peninsula however, is far from minor.

The next post in Relationships will cover the Thwaites Peninsula.

But it DID lose four metres. It lost it due to warm air and warm water. That is the interesting thing behind the breakup of Larsen C.

Have you looked up Thwaites Glacier yet?

Jovial Monk wrote on Jul 14^th, 2017 at 11:34pm:



A whole 1.3%. And we know your view. it should only accumulate in  Antarctica.

And how do you know it was behind the breakup of the Larsen C shelf? Crystal decanter again?

Jovial Monk wrote on Jul 14^th, 2017 at 10:27am:


roach tried to deflect from this but he DID tell Boobhead (PA/Off Topic/Ice Age) he has four on ignore.


Pathetic liar tried to deny it 


So roach cannot take the high moral ground with me putting some posts out of reach of deflection etc. ahahahahaha!

Oh. Talking about temperatures being above average temperatures. Instead of absolute records.

IT'S HAPPENED

One of the biggest icebergs on record has broken away from Antarctica, scientists have said, creating an extra hazard for ships around the continent as it breaks up.

The 1-trillion-tonne iceberg, measuring 5,800 square kilometres, calved away from the Larsen C ice shelf in Antarctica sometime between July 10 and 12, scientists at the University of Swansea and the British Antarctic Survey said.

The iceberg has been close to breaking off for a few months. Throughout the Antarctic winter, scientists monitored the progress of the rift in the ice shelf using the European Space Agency satellites.

"The iceberg is one of the largest recorded and its future progress is difficult to predict," said Adrian Luckman, professor at Swansea University and lead investigator of Project MIDAS, which has been monitoring the ice shelf for years.

"It may remain in one piece but is more likely to break into fragments. Some of the ice may remain in the area for decades, while parts of the iceberg may drift north into warmer waters," he added.

The iceberg, which is likely to be named A68, was already floating before it broke away so there is no immediate impact on sea levels, but the calving has left the Larsen C ice shelf reduced in area by more than 12 per cent.

The Larsen A and B ice shelves, which were situated further north on the Antarctic Peninsula, collapsed in 1995 and 2002, respectively.

"This resulted in the dramatic acceleration of the glaciers behind them, with larger volumes of ice entering the ocean and contributing to sea-level rise," said David Vaughan, glaciologist and director of science at British Antarctic Survey.

"If Larsen C now starts to retreat significantly and eventually collapses, then we will see another contribution to sea level rise," he added.

Big icebergs break off Antarctica naturally, meaning scientists are not linking the rift to manmade climate change.

The ice, however, is a part of the Antarctic peninsula that has warmed quickly in recent decades.

"Abstract:
The West Antarctic Ice Sheet overlies the West Antarctic Rift System about which, due to the comprehensive ice cover, we have only limited and sporadic knowledge of volcanic activity and its extent. Improving our understanding of subglacial volcanic activity across the province is important both for helping to constrain how volcanism and rifting may have influenced ice-sheet growth and decay over previous glacial cycles, and in light of concerns over whether enhanced geo-thermal heat fluxes and subglacial melting may contribute to instability of the West Antarctic Ice Sheet. Here, we use ice-sheet bed-elevation data to locate individual conical edifices protruding upwards into the ice across West Antarctica, and we propose that these edifices represent subglacial volcanoes. We used aeromagnetic, aerogravity, satellite imagery and databases of confirmed volcanoes to support this interpretation. The overall result presented here constitutes a first inventory of West Antarctica’s subglacial volcanism. We identified 138 volcanoes, 91 of which have not previously been identified, and which are widely distributed throughout the deep basins of West Antarctica, but are especially concentrated and orientated along the >3000 km central axis of the West Antarctic Rift System."

Do you know where the Rift is that the article mentions, Loser Lees?

Proof?

https://www.nap.edu/read/12168/chapter/10#94

I suggest you do some reading.

or

"The Thwaites glacier is one of the most rapidly changing in Antarctica. It’s been the focus of considerable attention in recent weeks, after scientists suggested that this sector of the huge West Antarctic Ice Sheet was already on route towards collapse due to warming ocean temperatures. A major collapse of this part of the ice sheet could have dire consequences worldwide, with a global sea level rise of potentially up to 1m. Some models suggest this could take place comparatively rapidly, within a few centuries.

But hidden beneath the kilometres of ice in this rapidly changing part of the continent is a largely unexplored geological feature: the West Antarctic Rift System, a strip of volcanic activity thought to extend for more than 3,000km across the Antarctic continent, provides further heat to melt the ice sheet from below."
