When ice ages have warm periods, glaciers melt. It also happens when ice ages are moving toward an ending.
Trouble with that is that the Milankovitch cycles won't hit a combined minimum for another 10,000 years.
A massive river of ice, the glacier by itself is responsible for 20 percent of total ice loss from the West Antarctic Ice Sheet today.
On average, it shed 20 billion tonnes of ice annually from 1992-2011, a loss that is likely to increase up to and above 100 billion tonnes each year, said the study.
This is equivalent to 3.5-10 millimetres (0.14-0.4 inches) of global average sea-level rise over the next 20 years.
The global mean sea level rose by 3.2 mm in 2010itself a near-doubling from the rate of two decades earlier.
The European Space Agency said last month that the West Antarctic ice sheet was shedding ice at a much faster rate than beforecurrently at about 150 cubic kilometres (36 cubic miles) per year.
Climate scientists are keeping a worried eye on the mighty ice sheets of Greenland and Antarctica, as continued losses could threaten vulnerable coastal cities with dangerously high sea levels.
Last year, the United Nations' climate science body, the Intergovernmental Panel on Climate Change (IPCC) projected sea levels would rise between 26 and 82 centimetres (10.4 and 32.8 inches) by 2100.

A doubling in two decades. Suppose that turns out to be the rate of increase. By 2033, 6.8 mm per year. By 2073, 27.2 mm per year. And that is without any nasty surprises from some of the massive ice shelves.

A doubling of WHAT? the melt rate of Pine Island Glacier? Or Sea Level Rate? This little glacier may be responsible for "20% of the Antarctic melt" stream, but it ALONE aint gonna do JACK SHIT to global sea levels.. Get a grip.. Better YET -- get your bearings, go on Google Earth -- Find Pine Island and LOOK at this miniscule part of that continent.
To give you CONTEXT for that photo --- here's a map... PIG MARKS THE SPOT..
Women and children and warmers FIRST -- to the shuttle craft -- The mother ship is coming.
WAG- wild ass guesses.
The equipment in place to measure ice movement have very few data points. It is easy to adjust them to preconceptions.
IanC said:Also, if the tips of floating ice shelves didn't break off occasionally they would stretch to the tropics.

Do you really want to stick with your claim that melting 192 cubic miles of glacial ice would have NO effect on sea level? Really? REALLY? What drugs have you been taking?
Once more, the denialists have proven their skill at hysterics and red herrings. It's probably not what they set out to do, but at least they accomplished something.

Draw me the surface equivalent of 192 cubic miles of PIG ice on that map of Antarctica and I'll tell ya if im worried.. My guess is -- it would look like one ice cube in my 32 Oz sweet tea.

Do you have any evidence that supports your implication that any of that data has been altered to fit someone's preconceptions?

They have before.

Since most of that glacier is not located on the surface of the ocean, your analogy is irrelevant.
