If you think about ice ages with 140 metre lower sea levels and how over a short few thousand years these turned into our current sea levels. Not so dissimilar a rate of change they average 3 metres per century. Would those melts or shifts have been straight line? Not very likely.
we have what are in geological terms virtually stable sea levels where rebound and techtonic shifts are as significant as the background rises and falls. Image the flood of funding for research if the German Scientist had said thing were drifting slowly up and down. To feed his family he needs to talk it up not down.

Lake Agassiz formed from melt water of the Laurenide ice sheet, and became the largest freshwater lake ever known. The jump in sea levels when Agassiz broke through an ice dam around 8000 years before present was apparently considerable, and could have led to the Noah's flood and Atlantis legends. It is likely that the Black Sea was a fresh water lake that was inundated from the rising Mediterranean that itself had been a flat fertile valley with a shallow sea but the sea level rise led to huge inflow through what is now the straight's of Gibraltar. It is difficult to come up with anything in the modern geography of the world that could equate to Agassiz flooding; yet that is what the alarmists are always claiming. Where could such a flood of meltwater come from in the next century?

The Western Peninsula of Antarctica is pocket change compared to the large cash reserve that blew north. nautonnier: I live in the lake bed. There is no comparable place on earth.....period.

As far as I can make out Antarctic Ice is about 50% [or 1.1 million] sq kms above the long term average at present.
In about 3 weeks time, it will stop melting and the sea will start to freeze again.
In the meantime, there is a lot of extra sunlight just being reflected ...
More mathematically inclined people than me can probably work out how much heat is being reflected away in 24 hr daylight.
I suspect the figure is large, and will give next year's ice sheet a flying start.

www.inquisitr.com/1780823/scientists-drill-through-antarctic-ice-shelf-and-discover-bizarre-lost-world/A “lost world” never seen or touched by mankind before has been discovered by a group of scientists using a hot-water drill and underwater robotic vehicles to break through the Antarctic ice shelf. Jim Morrison once said that in this world, there are things known and unknown, and in between are the doors. But in this in this case, it would appear that it was a sheet of ice separating man from one of his last great discoveries.

Interesting Sig and there is obviously a need for more research:

Interesting Sig and there is obviously a need for more research: It's amazing how fast ice melts at minus 30degC though perhaps it nay be helped by hosing hot water into it - that would be a recent change.

I suspect that they never overturned before CO2 became a problem.

-Giant atmospheric rivers add mass to Antarctica's ice sheet- www.sciencedaily.com/releases/2015/01/150120112206.htmExtreme weather phenomena called atmospheric rivers were behind intense snowstorms recorded in 2009 and 2011 in East Antarctica. The resulting snow accumulation partly offset recent ice loss from the Antarctic ice sheet, report researchers. ~snip Of course the caveat is....more research is needed to see how global warming affects blah blah blah.... ?

I suspect that they never overturned before CO2 became a problem. there may be a shred of truth in that in that the Arctic was not flooded with reporters taking billions of photos of everything ice until CO2 became a perceived problem.

Still quiet on here? Does that mean Sea ice is back in the pack of other years?
To me it looks like the pre 05' years with both a total melt out in Ross and the Weddell Polynia making an appearance? Is this the first signs of the flip in the naturals that we have seen in the Antarctic?
We are also in the portion of melt season where we see major calvings ( as wave action is allowed free play on Shelf fronts) so worth keeping an eye on?
Then we need to see if we get a poor ice gain re-freeze as storms eat away at the ice edge over Weddell and Ross Seas?
