    Add to that the news that last month's ice extent was the largest on record...

    http://nsidc.org/arcticseaicenews/
    In the Southern Hemisphere, autumn is well underway, and sea ice extent is growing rapidly. Antarctic sea ice extent for April 2014 reached 9.00 million square kilometers (3.47 million square miles), the largest ice extent on record by a significant margin. This exceeds the past record for the satellite era by about 320,000 square kilometers (124,000 square miles), which was set in April 2008.

      Sea levels have fluctuated considerably before and will continue to do so in the future. No finer example of this can be presented than Cosquer cave near near Marseilles, France. It is the site of some extraordinary prehistoric paintings ranging from 19 to 27,000 years old (Upper Paleolithic). The entrance to this cave is now approximately 35 to 37 meters (115-121') underwater. This means that sea levels have risen well over one hundred feet since these cave paintings were made.

        So what is going on? This seems to counter the "runaway meltdown" referenced in the OP.

          Why does the idea of this being an hypothesis bother you?

          It doesn't. It's just that i said a lot more than one thing, and many of the things that i said were factual. I'm trying to figure out what, exactly, is the hypothesis. There are a large number of them that you could potentially draw from the facts (there are five different glaciers involved, each with their own distinctive grounding lines and upstream features), so i'd like something specific to actually think about.

            Each winter, you see sea ice form in both the Arctic and Antarctic. Each summer, most of it goes away again. The sea ice has some influence on the behavior of the non-floating ice (which is what's at issue in the OP), but many other factors also influence it. So, to a large extent, we're talking about two different things.

                Hmmm...so due to climate change the arctic ice is rapidly melting while current shifts have the antarctic ice slowly growing.

                The arctic ice is 610,000 square kilometers below average while the antarctic is 320,000 square kilometers above average.

                For the planet as a whole the ice is almost 300,000 square kilometers below average.

                  Arctic sea ice extent for April 2014 averaged 14.14 million square kilometers (5.46 million square miles)... 270,000 square kilometers (104,000 square miles) above the record April monthly low, which occurred in 2007

                    Um, Bill...

                    Showing us something 'above the record low' is not showing us that it's not 'below average'.

                    Arctic sea ice extent for April 2014 averaged 14.14 million square kilometers (5.46 million square miles).

                      This is wrong. Antarctic ice is 320,000 sq.km. above the record, not above average.

                          I wasn't trying to show that. I was showing that it looks to be recovering from the 2007 low by quite a large extent.

                          The ellipses was to omit what Tiggy had quoted in his post, as it was unnecessary to the point I was making. If climate change is really affecting it the way it is portrayed, it should not have recovered over 50% of what was lost from the average normal, should it?

                            It recovered the very next year. What you need to establish are trends, not yearly quantities. The trends are shown in the graphs provided, and they're very clearly downward. The quantities are higher than the record low, but they're still well below average.

                                Obviously the Antarctic is a thief! It is stealing ice from the Artic. I bet it is those penguins. Never trust a suit.
