The sea ice surrounding Antarctica, which, as I reported in my book, has been steadily increasing throughout the period of satellite measurement that began in 1979, has hit a new all-time record high for areal coverage.
The new record anomaly for Southern Hemisphere sea ice, the ice encircling the southernmost continent, is 2.074 million square kilometers and was posted for the first time by the University of Illinois at Urbana-Champaign’s The Cryosphere Today early Sunday morning.
The previous record anomaly for Southern Hemisphere sea ice area was 1.840 million square kilometers and occurred on December 20, 2007.
Global sea ice area, as of Sunday morning, stood at 1.005 million square kilometers above average.

There is always some global catastrophe on the horizon for which members of the demoRAT-COMMUNIST seek to remove our Freedom and our money…. see global cooling, rain forest, acid rain, ozone layer, nuclear annihilation, et.al. Anyone care to speculate on the next global catastrophe is next after global warming is finally debunked?
Another Drudge hit. The message is getting out.
By george, that’s a hockey stick…WITH ACTUAL MEASURED DATA even!

Please took at total area rather than anomaly, you will see total area is currently down from prior peaks.

Kindly note that Antarctic Winter seasonal peak sea ice extent won’t be reached until around July 23rd. The extent anomaly means that Antarctic sea ice is currently 2+ Million Km2 above the 30 yer average for this date, not for seasonal maximum extent.

“…Kindly note that Antarctic Winter seasonal peak sea ice extent won’t be reached until around July 23rd. …”
I think Sept 22 to Aug 1 is more accurate…
What little such cooled water runs off, it does occasionally freeze in underwater “ice falls” as it runs into the colder sea water – but such ice falls are both very rare, and of very, very limited extents (10 and 50 meters wide, less than 500 meters long.) Compared to the current Antarctic sea ice extents anomaly of 2,000,000 “excess” square kilometers of 2 and 3 meter thick “excess” sea ice for today’s date, such run off from the land ice is trivial.

Yes- what was i typing? Sheesh.
No, the Arctic sea ice minimum occurs (on average) between 15 September and 25 September each year. The Arctic maximum extents occurs slightly after the spring equinox (NOT during the Arctic winter!) in early April.
The Antarctic sea ice extents maximum occurs just a bit later between 1 October and 15 October. The Antarctic sea ice minimum occurs in mid-February.
You can see these off-equal maximums and minimums as a series of double peaks in the yearly total sea ice extents when both Arctic and Antarctic are added together. But such mindless additions are worthless: The two CANNOT be compared directly each other.
Sea ice area anamalies and sea ice extents anomalies are the DIFFERENCE between the established daily average area (or extent) and the day’s actual sea area. Thus a record high sea ice anamaly IS the highest ever recorded difference between a measured sea ice area, and that day’s “expecetd” sea ice area. Such a record sea ice anomaly can be set ANY DAY of the year, in ANY season of the year, regardless of that day’s average value of 3.0 million sq kilometers, 12 million sq kilometers, or the maximum of 14 million sq kilometers. A sea cie anomaly record can be set at any time; a record high sea ice area (or sea ice extents) can reasonably only be expected to occur near the yearly maximum. In the Antarctic, such a record sea ice extents is not likely to occur until mid to late September.
but, in truth, a +2.0 million sea ice extents anomaly is so high so early in the year that a record may be exceeded much earlier. We shall see.
Meaningless comparison. The Antarctic sea ice extents is so much closer to the equator throughout the year than the very small arctic sea ice areas that solar reflection from the excess Antarctic sea ice around the Antarctic continent is much, much more important to the earth’s energy balance than the Arctic sea ice. In fact, from today’s arctic sea ice extents, the more the arctic ice melts after late-August, more energy is lost from the arctic ocean through evaporation, convection, radiation, and conduction than can be gained from solar absorption.
Are these changes over the last 25-50 years any real indicator of what trends have developed over thousands. Can we really predict anything with such a short time sample?

I haven’t read all the comments, so someone else may have already found this for you …
Hey, I got an idea. How about we pick on the side of caution? Being right has too much risk long term. For now get your car ECU recalibrated and save fuel while lowering the crap comming out the pipe. It’s an so easy it is silly.

Lastly, please remind me the negative impacts of acting against climate change. Are you people afraid of cleaner air & water, and seeing a workforce shift to renewable energy development from digging in coal mines? Personally, I’d much rather see a consumption based tax focused on what you buy rather than what you make or already own. Get rid of property and income tax and let’s implement a consumption based tax (exempting food)!”
1. I cannot count the number of times I’ve heard this “okay, you caught us. There is not any real evidence of this, BUT…we are lying for the good of humanity!” spiel.
The answer is the same: we don’t believe in your religion. And that’s all this is, articles of faith based on hope and good wishes.
Everything you people say is predicated on your faith that (1) all the things we’re doing are bad, and (2) all the things we science cultists WANT to do are good. You ignore un intended consequences. You ignore the fact that free markets are always correct and planned economies invariably are f***ed up beyond your wildest nightmares.
There is no “clean energy solution,” there is only YOUR hopes and dreams being hijacked by snake-oil salesmen like Al Gore. When government fixers get the hell out of the way, the best solutions will always arise, as they always have. And the moment something better comes along, the old ways will be supplanted, because THATS WHAT WORKS!
Never occurs to you people that if “clean energy” worked it would be in use right now. You think the market is all manipulated because you want to manipulate it yourself. A thief always thinks others are dishonest.
You, Al Gore, and B. Hussein Obama get the **** out of the way! and the free market will determine what is best for the greatest number. Your way always leads to cronyism, despotism and poverty for the masses..
Sit down and shut the **** up unless you have a solution that doesn’t require taking other people’s money and giving it to your cronies.
Odd you ask that: The IMMEDIATE NEGATIVE effect of acting as YOU require against safer, inexpensive energy for all is the immediate death of millions of lives each year, and the continued misery of life for billions who are forced to give up access to improved and safe water, sanitation and sewage control, refrigeration and safe heating, lights, heat, better roads, more rails, and improved food storage and handling.
For what? For nothing! The misery and deaths YOU require in YOUR demands between now and 2100 to make CO2 “expensive” will have NO MEASURABLE IMPACT on global temperatures.
You REQUIRE the immediate death of millions for your schemes and YOUR tax requirements. Against the 5% chance of avoiding a beneficial increase in temperatures of 2-3 degrees. That is, if the world temperatures even increase that much between now and 2100. Thus far this century, they have been decreasing you know. 8<)
No one has mentioned albedo and feedbacks.
The albedo of water is less than 0.1 and the albedo of SH sea ice (mostly snow covered) is around 0.6. Where the new ice has formed, reflection of solar radiation back out toward space has gone from 10% to 60%.
It’s a common misconception that south of the Antarctic Circle doesn’t get that much solar radiation even in summer. In fact, around the [SH] summer solstice, it gets more daily solar radiation than anywhere else on Earth.
Increasing sea ice and the consequent albedo increases cause a major cooling feedback. The more sea ice that forms, the colder it gets.
We know that around the start and end of inter-glacials, the climate undergoes periods of rapid warming and cooling. Rapid being from a few years to a few decades What causes these rapid changes IMO is formation of new sea ice (cooling) and melting of old land ice (warming).
False. Dead wrong in the long term trend, though your observation of the past week may be correct.
The Antarctic sea ice anomaly has been steadily increasing since 2007 through EVERY season of the ice year. As noted above, the Antarctic sea ice anomaly once “touched” 1.0 million sq km^2 six times between 1970 and 2007. Since then, it has regularly exceeded 1.2 million km^2, and has been continuously increasing since May 2011. Today’s sea ice anomaly of 2.0+ million km^2 merely continues that long-term trend.
That a recent increase of 100,000 km^2 only added to a three-year (or a longer, slower 14 year) trend of ever-increasing Antarctic sea ice marks only a short period in a far longer, far more important interval.
Is this even a serious comment? The record was for the biggest anomaly since record keeping began. The southern hemisphere sea ice extent set an all time record last year. Sea ice area will not peak until August or September. There is no difference between area and total area. Do some research before posting next time.

Bloody cold here in Brisbane, too. What happened to the Warmest Winter Ever?
Tony says: June 29, 2014 at 10:10 am
…how do you interpolate the data when they show photos of melting glaciers compared to years ago and when they show the same photo…and the polar bear area (ice) diminishing. …
Hi Tony,
Good question.
I find it interesting that most things claimed as ‘unprecedented’ are not so:
Here is a bit of interesting data on recently retreating glaciers (yes, in some places they are retreating, but is it unusual?) We can see from the data below that they are only now exposing areas completely free of ice previously in this interglacial (The Holocene). Some will argue that yes, we know that, but we fully understand the earlier Holocene warmings.
Memo to Eric L: CO2 is not pollution, it is a colourless, odourless gas essential for the process of plant photosynthesis and therefore life on Earth.
“… Carbon Dioxide (CO2) is not pollution and Global Warming has nothing to do with pollution. The average person has been misled and is confused about what the current Global Warming debate is about, greenhouse gases. None of which has anything to do with air pollution. People are confusing Smog, Carbon Monoxide (CO) and the pollutants in car exhaust with the life supporting, essential trace gas in our atmosphere, Carbon Dioxide (CO2). Pollution is already regulated under the Clean Air Act and regulating Carbon Dioxide (CO2) will do absolutely nothing to make the air you breath “cleaner”. Carbon Dioxide (CO2) is actually plant food. They are also misled to believe that CO2 is polluting the oceans through acidification but there is nothing unnatural or unprecedented about current measurements of ocean water pH and a future rise in pCO2 will likely yield growth benefits to corals and other sea life. Thus regulating Carbon Dioxide (CO2) emissions through either ‘Carbon Taxes’, ‘Cap and Trade’ or the EPA will cause energy prices (electricity, gasoline, diesel fuel, propane, heating oil etc …) to skyrocket …” :

How important is the circulation? This high-pressure system over the Atlantic reigns many days. Brings cooling in Europe and storms in North America. Cools the Caribbean Sea and the Gulf Stream inhibits.

Very important is the temperature of the ocean south of Africa. There are crossing the warm currents.

It is easy to predict that the global ice this year reaches the highest state since 1979.

Please see the blood circulation in the lower stratosphere over the Atlantic Ocean at an altitude of about 17 km. This arrangement blocks the circulation. Simultaneously prevents the formation of hurricanes.
