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.

REN, it looks like a positive AAO will be the rule as we head into July. Not much blocking.

How about some of you smart folks here poke holes in this for me?
I think you could be right – global sea ice, for the physical reasons you outlined, could be the best integrating index of global warming or cooling. Averaged over a few years.
Salvatore we are working on the same wavelength solar. I agree July.

Umm. You are probably not aware that your suggestion is exactly BACKWARD
with respect to carbon dioxide (CO2). Any hydrocarbon (you know, like most of
the mass of gasoline?) when burned completely will yield only two products, CO2
(carbon dioxide) and H2O (water vapor). These are the two most effective greenhouse
gases. So, your suggestion to save fuel will result in a car emitting MORE greenhouse
gas, not less.
You really need to study your chemistry. The trace pollutants like nitrogen oxides,
ozone, and carbon monoxide (note–that’s different from carbon DIOXIDE) may go
down a little bit in your scenario, but all those cars that have been “recalibrated’
will be putting more greenhouse gases into the atmosphere.

Satellite measurements began in 1973. The period beginning in 1979 corresponds with the maximum extent in the Arctic. Cherry picking?
And the period beginning in 1979 corresponds with the minimum extent in the Antarctic, the extent anomaly was about 2.5 Mkm^2 in 1973.
And the period beginning in 1979 corresponds with the maximum extent in the Arctic. I always had the impression that the year 1979 is used, because that is what NSIDC shows as the record on consequence. I have never seen NSIDC use any other graph with a more complete data set. Why is that?
Severe weather will lash through areas from the Plains to the Midwest Monday into Tuesday, hitting some of the major cities in the United States, including Chicago, St. Louis;, Detroit, and Kansas City, Missouri.

It would be great to see someone with enough knowledge develop a post on this Gulf Stream and Arctic Ice Sheet topic. Including Gulf Stream and AMO, sunspots, and whatever other related bits of info have been mentioned here.

Hey, I got an idea. How about we pick on the side of caution? Being right has too much risk long term.
====================================================================
I love this particular argument. The “Precautionary Principle”.
I am not a religious person, but I was raised a Roman Catholic. This same argument would seem to say that I should go to church every week and pray feverishly for my immortal soul, because me being wrong about there being no God has “too much risk (very very very VERY) long term”
I don’t believe in God, as it doesn’t quite pass the smell test (for myself), nor do I buy that man is affecting our climate in anyway that could be considered “catastrophic”.
My apologies to anyone that is religious, I do not mean to offend.
One man’s opinion.

Hi
Sorry but the article is completely wrong in the first paragraph
“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”.
You can see from the below graph it is still lower than the maxima for all years measured
http://arctic.atmos.uiuc.edu/cryosphere/IMAGES/seaice.area.antarctic.png
What the writer means is it record high for this time of year. Problem is that when this gets reported on other sites that will be forgotten as they just do the sound bite.
Can you correct please?
Andy
Hello RACookPe1978. You say ”..but the top-of-atmosphere solar radiation is at its MAXIMUM of 1410 watts/m^2 the first weeks of January when antarctic sea ice is exposed to 24 hours of sun each day!” Is that taking into account that around January the Earth is approximately 5 Million Kilometres closer to to sun?

I do not know if you noticed that the biggest increase in global ice is in September.
Look at the chart. I predict that it will record. We’ll see in October.

Why do I think so? Because you can see the temperature drop over the poles. See temperature anomalies.

Let’s see the temperature in the lower stratosphere over the southern polar circle.

@ren…I see a new sea ice anomaly record at 2.112 mil/km2 from today,s update. I noticed several months ago that the sea ice growth rate increases when portions of the jetstream move in closer to the continent. Similarly, the rate slows down when the jet pulls away.
If the sea ice growth rate continues at a similar pace for the next 3 months, then I would think that Antarctica will receive more respect for it,s position in the climate story. I think that it was only 2 weeks ago that the anomaly had shrunk to 1.0 mil/km2. So it has now gained 1.1+ mil in around 14 days. That is probably a record of it,s own.
Just a sociology/anthropology/political science observation:
Movement fadists call the last data point a trend. If this were lost ice, they would classify this as a trend.
Scientists and normal people call this last data point an anomoly in regards to the other data points.
The fadists gleefully comply…this one time….and adopt the anomoly designation.
EMPIRESENTRY:
“Movement fadists call the last data point a trend. If this were lost ice, they would classify this as a trend.”
When the temps fall to below normal the Warmists tell me “temperature isn’t climate.”
When we have fewer hurricanes than the Alarmists predict, they tell me “weather isn’t climate.”
When a hurricane comes ashore, when a summer heat wave happens, guess what those same people tell me?

The Antarctic sea ice anomaly as well as the Global anomaly can fluctuate by 100’s Km2/day, due to calving events, Polar storms, days where losses occur at both poles simultaneously, etc. No big deal. A few weeks ago (May 15,) the Global Sea Ice anomaly fell over 400 Km2 overnight, continued a downward trend for a few days, but was back to “normal” a week or so later. There may be some artifacts of data reporting involved, also.

Thanks for the explanation.
Yes, that yearly orbital variation of distance is the reason the top-of-atmosphere solar radiation varies so much. Closer to the sun on January 3-5, furthest July 4-5-6 each year.
We really ought to be talking about Antarctic ice mass, which is on an accelerated decline:
http://climate.nasa.gov/news/242/
“Meanwhile, measurements from the Grace satellites confirm that Antarctica is losing mass (Figure 1). Isabella Velicogna of JPL and the University of California, Irvine, uses Grace data to weigh the Antarctic ice sheet from space. Her work shows that the ice sheet is not only losing mass, but it is losing mass at an accelerating rate.
“The important message is that it is not a linear trend. A linear trend means you have the same mass loss every year. The fact that it’s above linear, this is the important idea, that ice loss is increasing with time,” she says. And she points out that it isn’t just the Grace data that show accelerating loss; the radar data does, too. “It isn’t just one type of measurement. It’s a series of independent measurements that are giving the same results, which makes it more robust.”
