NASA scientists will use the results of the project to develop models
for the processes they measure. Rignot said he could not speculate as
to when they might be able to create reliable models that will predict
ice shelf breakup, glacier speedup and the subsequent rise in sea level.
Ice shelves themselves don’t contribute to sea level rise, but their
disappearance allows the glaciers that feed them to flow freely and
more quickly into the ocean.
And still no sigh of the WUBBER DUCKS!!!!!!!!!! This story as with NASA are rehashed scare mongering for very young children and all the BBC twits .

What the scientists do know from satellite data [No Wubber Duckies] and some past studies is that the ice shelf is definitely warming and changing. Rignot said Larsen C is thinning at the north but possibly thickening to the south. The region receives some of the heaviest precipitation on the entire continent, most of which is a polar desert.
Satellites have observed melting on the shelf surface, Steffen noted. “We can see these melt waves going across the entire Larsen C that did not happen earlier on, like 10 years ago,” he said.
Retreat Summary
Since the late 1980s, a number of Antarctic ice shelves have retreated. This table gives an overview of retreat events as of early 2008.

The cow tax is a silly idea and will do more harm than good.
Problem is whilst the UK is meeting and exceeding its landffull targets, recycling, starting to get better non incinerators in place;
Ireland is way behind on sorting its landfills, poor recycling and previous damaging incinerator policy (now binned)

http://www.independent.ie/national-news/cabinets-incineration--policy-goes-up-in-smoke-1070799.htm
Ireland put through a damaging Poolberg Dublin incinerator a year ago, though since rejected/cancelled two more, with better future plans for MBT/AD facilities alongside better recycling /composting infrastructure.
This is the best way Ireland can meet its individual emissions targets (not silly cow taxes which will be opposed, then binned); although lets compare the whole relative MMGW impact of this in Ireland compared to that of the UK, Germany, USA, India or China ; its microscopic.

The Map below shows the real nature of the problem and the not so massive contribution from Ireland. Where are the main problems?
Answer: USA, China

"This earth has tolerated far warmer temperature's in the past and the world survived."
Yep, but not since the Dinosaurs, also their weren't billions of folks living at sea level in cities during the Age of Dinosaurs, re1-5degrees C temperature rises. Background climate chamge is natural, enhanced MMGW, and its massive rate of warming, going on now on top of the natural process, ain't natural, and ain't explained by the natural (these are going into long term cooling)
The Thames barrier has been used 108 times 1982. Massively over its design raise frequency, having 2x rising levels, overtopped in decades, exposing £90bn of City infrastructure. It will be a White Elephant!!!!!!!! Another barrier needed further out in the estuary in a several decades.
"When the Thames Barrier was being designed in the 1970s, global average sea levels were rising at about 1.8 millimetres a year and global warming was not seen as a threat, but in the past 15 years the rate has nearly doubled to about 3.1mm a year and many scientists expect it to accelerate still further."

Opphs mad; time to swop the wubber ducks for hand bailers and scuba mask. Unlike Sceptics Coral doesn't tell fibs!
New warning over 'catastrophic' sea level rise, scientists claim
Sea levels could rise by a "catastrophic" 10 feet by the end of the century – putting millions of people at risk of flooding with coastal cities such as London, New York, Tokyo and Calcutta submerged, according to a new study.

I be long turned into carbon by then, adding another nano-mm to the great tide, and for those poor folk who might drown move to the Scottish highlands their landmass is rising and I have read they could do with a few more bods........Stop this scare-mongering bluebottle lots of unstable folk/children might read your post.......I trust the wubber ducks, we all should.

The warmist wally's who instill terror into young children should take note; Africa has been known to be even hotter and dryer in the past. With droughts lasting for centuries ,its time for all mad believers of man made climate change to stop all the fables and seek medical help for their disorders. The lucky one's in Britain can get this help for free: via the NHS
Catastrophic droughts in Africa are the norm, claim scientists - Telegraph
The study shows regular periods of dryness, particularly droughts in the 30-40 year range. Some have even lasted centuries.
