A new record: the most sea ice in Antarctica in 30 years by extent and by volume

Translated by Google from this press release in German at the Alfred Wegener Institute in Germany:

Never so much sea ice at Antarctica in the last 30 years

In light of global warming, it seems paradoxical that the sea ice cover of the Southern Ocean has covered a larger area in the past month than in the last decades. Only in the mid-70s was observed a similar expansion.

Average sea ice extent in September (1973-2013) with trend line

Seasonal variability of sea ice extent (as at 13.10.2013)

The means were 19.48 million in September 2013 square kilometers, an area once covered more than 50 times larger than Germany with sea ice. The absolute maximum of 19.65 million square kilometers was reached on 18 of September. Although this maximum in the ice-covered surface can not be equated with a maximum of the total volume or mass, suggest that sea ice physicist Marcel Nicolaus and Stefan Hendricks from the Alfred Wegener Institute (AWI) “This winter there is in Antarctica as much ice as long gone, if it has ever been since the beginning of the regular satellite observations ever so much sea ice.”

To be able to make such statements in certain future, the researchers of the Alfred Wegener Institute is currently also the thickness of sea ice in the Antarctic work together with colleagues from different institutions that they can derive from satellite observations. In the Arctic, it has recently become possible, although there are significant differences between Arctic and Antarctic. The snow is thick, inhomogeneous and does not melt completely in summer. In addition, sea ice is formed at the top, a phenomenon that is encountered less frequently in the Arctic. Then there can also be calculated from the thickness and extent of sea ice volume in the future.

Minimum sea ice concentration on 22 February 2013

Sea ice concentration maximum at 18 September 2013

The ice-covered area of ​​the Antarctic Ocean grows each year by its minimum at the end of the Antarctic summer (February) of three to four million square kilometers on a multiple (approximately five to six times as much) to the maximum at the end of winter (September). Here, however, there are big regional differences, so that the Antarctic sea ice to be regarded as really a puzzle of different ice cover and assess.

Although over the last few years an increase in the total ice cover in winter and summer is observed, for example, it takes the tip of the Antarctic Peninsula, especially in the summer from clear. While the Antarctic Peninsula has warmed significantly in recent decades, the temperature remained stable in other regions.

These differences and the general increase of sea ice in many areas resulting in large part from changes in the wind that drives the sea ice more apart. On the other hand the temperatures and winds from the Antarctic continent have a strong impact on the sea ice belt around him. These are also differences to the Arctic, which contributes that the sea ice behaves so differently in both polar regions.

To better understand all of these contexts, the AWI has conducted two winter experiments with the research icebreaker Polarstern in the Weddell Sea in recent months. In these expeditions, the scientists have ever encountered thick, compact ice, after which they base their theory of the maximum of the ice mass. In addition to measurements during the trip, a variety of automatic measuring stations was deployed on the sea ice. This now continuously measure the thickness, temperature and movement of sea ice and its snow cover and send their data via satellite to the AWI and other project partners.

Reports, photographs, maps and data of these experiments are here presented and commented. More information is also available on the fact sheet on sea ice as well as the websites of the sea ice physics section available.

But it is even worse than you thought!
Those 19.65 million sq km’s of Antarctic sea ice (now at all-time recorded highs!) surrounds the Antarctic ice shelves (1.5 million sq km’s) which turn surround the 14.0 million sq km’s of Antarctic land mass (96+ percent of which is permanently covered by land ice of varying thicknesses)
So, the total Antarctic “ice” reflecting area is 1.5 + 14.0 + 19.65 = 35.15 million sq km’s of highly reflective land ice, sea ice, and snow. The “edge” of this Antarctic ice cap is a circle extending fro the pole upwards past latitude 60. Each added sq km reflects a LOT of energy at that latitude, many times more than can be absorbed at latitude 80, 82, or 83.
So, in the earth’s total heat budget, what matters more?
Losing 1.0 million sq km’s of sea ice up in the Arctic (that ice up high between latitude 82, 83, or 85 degrees? Up high where the air mass is 4 to 5 times what it is at latitude 60? Up high where the open water albedo is 4.0 to 5.0 times larger than at latitude 60? Remember, at latitude 80-85 from later August through early May, more energy is lost from the open ocean than can be absorbed from sunlight on that open ocean when it is exposed by melting the sea ice. In the high Arctic under today’s actual conditions, losing sea lice to the open ocean cools the planet.
Or adding 1.0 million sq km’s to the edge of the Antarctic sea ice near latitude 60? At that latitude – characterized by higher solar angles for longer periods of time over more days of the year – each sq km of new sea ice reflects more and more solar energy, thus – again! – cooling the planet.

AR5 says that at the end of this century we will see a decline in Antarctica’s sea ice extent. It also says we will see more snow in Antarctica and yet says they don’t know why the current extent is so high. An abstract I read in the last few days said that more snow in Antarctica leads to a greater sea ice extent. Some CAGW scientist have speculated that ‘climate change’ leads to melting sea ice which leads to an increase in Antarctica’s sea ice extent. After the hottest decade on the record Antarctica’s extent is at its highest on the record.
Q) Could it be that climate scientists don’t know what is really going on?
Q) Could it be they are trying to sell me a pig in a poke?
Q) Could it be that funding has lead them astray?
Q) Could it be that one day they will go on trial for fraud?

In the discussion over at Judith Curry’s site on the Stadium Wave, part of the speculation was that the AMO was a big part of both the loss of ice up north, and the addition down south. When the AMO turns warm, it saps the energy from the southern Atlantic, thus allowing for cooler waters and hence more ice formation. That was just a discussion Marcia Wyatt had with one of the posters, but she indicated it would be worth investigating.
I hope she does.

I was taught as a geologist 30 years ago that the arctic is variable due to continents and ocean circulation, the Antarctic less so.
Not news to those of us old enough to have avoided propaganda!!

UK Then read it in the original German where it makes a little more sense. It’s the nature of German syntax that always makes auto translations awkward as although basic word order is similar to English, and it ought to be given that old High German forms much of the basis of the English language, the placements of verbs and subjects determines how it should be read. A human can do this quite easily, quickly recognising the subject and making sense of it in English. Google translate just sees words.

It bothers me muchly to celebrate that which will kill many more (cooling) than either the status quo or warming. I am consoled only by the thought that Warmists will kill more than both with their energy starvation policies, if given the chance (so anything that blocks them is worthwhile).
But it still sucks.

Where has all the warming gone? Wo ist es geblieben?The answer gives the sun!Es war übertrieben!
In the arctic too, we see less melting and a record sea-ice recovery . Is this really just weather??
By the way, Alfred Wegener published the Hypothesis of the continental drift . His theory was a “moonshine” idea to 90% of the “experts” till the 40ies!

Interesting that the Arctic made the “turn” from minimum weeks ago, but the Antarctic lags weeks to make its turn.

Also, we should introduce Polar Bears into Antarctica. Plenty of sea ice.

IMO that might be a good idea if they were in danger of extinction (which they’re not), except they would prb’ly decimate the defenseless penguins there. They could be released well away from penguin-occupied areas into seal territories, but such an audacious act would cause warmers to cry havoc and let loose the dogs of hand-wringing.

But no need to get all denialist about it, the IPCC assures us that they have located the missing heat at the bottom of the oceans.

The debate about the AMO at Judith Curry’s site is about two conjoined phenomena: heat piracy and the bipolar seesaw.
I haven’t read that debate but if it is AGW hacks who are turning to the AMO to explain the cooling Antarctic, they may be missing one glaring implication. That the NH warming of the last 30 years has not resulted from heat
added to the climate system, anthropogenic or otherwise. It has just been borrowed from the SH.
Something similar could be said about our economic growth over the same period.

@Phlogiston – I do not know the players at Dr. Curry’s site well enough to have picked out if they were the alarmists or not. And Marcia Wyatt was neutral enough and scholarly enough that she did not favor one side or the other, so it was a pleasure reading her defense and explanation of her thesis.
But I do agree with you. The AMO is evidence of heat transference, not warming. Some parts will warm at the expense of others, the AMO just is the transport mechanism.

The top figure, Antarctic sea ice since 1973, shows what a profound global impact there was from the Pacific ocean climate regime change in 1976.
Its just a pity we don’t have this data going back another couple of decades.

Why was there a 2SD uptick in Antarctic ice extent in September, 2012?
That’s what this seems to show:

Because they need to be on permanent ice which is a long way from the sea-ice boundary in the winter.

How do they detect that it is permanent ice?
Sensors in their feet?
This is an interesting issue?

C’mon, Phildot, didn’t you see the National Geographic show on (Emperor?) peguins? They walk 60 miles inland over permanent land to their rookeries.

We are certainly in a cold spell that may get worse. Count nightcrawlers, bats, and grasshoppers. For many years now, the spring weather along the upper western states of the US has been cold, cold, cold, and long, long, long. Hot Summers and cold Summers are uncomfortable, but the effects are not devastating. An extended cold Spring puts everything back and results in decreasing populations of, for example, nightcrawlers, bats, and grasshoppers. I pay attention to these three things because I fish with two of them, and live with one of them.

Jim, I wish I could post the image I saw (it’s saved in my files) in a paper yrs ago showing IR emitted from earth to space (by satellite). It showed what you’d expect from tropical/extra-tropical spots, but showed CO2 acting the opposite in Antarctica — cooling the surface instead of warming. This, I figured, had to be due to a temp inversion causing the CO2-emitting layer (~40000 ft altitude) to be warmer than the surface! That’s an anti-GHG effect.
That might help explain the slight cooling of Antarctica.

OK, found an image of what I mentioned above — look at Fig 1.2 in the link below and particularly the third image for Antarctica — the CO2 “bump” is upward instead of downward! CO2 is emitting at a higher temp than the surface.
