Antarctic Ice Discussion

[stewfox]

Would be nice to say tha stew but the observations show high temp anoms across the continent and increasing mass losses decade on decade. Those being the facts isn't it 'wise ' to look for the reason we see this odd behaviour in the ice ( and learn from what we find?)

 

 

 

We don't have decades and decades of ice mass figures for the Antarctic.

 

Interesting graphs attached

I think you'll find your mass loss graph less than honest stew? Yes, I'll concede that some regions (esp the area opposite Australia) have seen an uptick in gains through increased snowfall due to the impacts of wind/pressure pattern changes and an atmosphere holding more moisture (esp. over a 'cold desert') but that does not really impact the scale of losses we are seeing/measuring there? We also see a decadal 'doubling' of losses , since the 80's, to losses there and the latest paper looking at modelled losses that include the uptick in winds around Antarctica show which promises much more of the same.

 

The planet is warming stew (oceans,land and atmosphere), what does your common sense tell you must be happening to the planets ice?

A remarkable turnaround in ice growth in Antarctica . And an anomaly retreat of over 1.25 million km2 in just a few days leaving the world sea ice anomaly negative . Anyone explain the Antarctic developments ?

In need a big drop in Antarctica as can be seen on the daily reports. A 400,000 sq km drop in the depth of winter in the last few days. That's not been seen in the last 30yrs , in need its rare to see any drop . Data error ?

Surprised KL hasn't updated us to the drop? He appears quite keen on Antarctic Sea Ice?

 

EDIT: Not that surprising stew? With the ice pressed so far north in certain areas it is just asking for a southern ocean storm to knock it off? We have seen 1 million drops in the past few years?

Seriously its a cause for interest

July 12th 1984 - 16.303 m sq km

July 12th 2014 - 16.230 m sq km

 

No Antarctic ice growth lol

No comment because there has been no  drop sensor error http://sunshinehours.wordpress.com/2014/07/14/sea-ice-update-july-14-2014-antarctica-sensorprocessing-error/

Seems real enough through all the other sites keith? Seeing as we have Nino type forcings maybe this will be a southern winter you'd rather not draw attention to? Don't worry though I'll step up!

Yes lets not mention record cold in Sydney.One of the coldest Junes ever recoded in the Antarctic so yes Grey Wolf warming up in The Antarctic http://t.co/xUUHQxfY7r

[Gray-Wolf]

Still not regained the sea ice cover that we lost? In the cold southern world of keiths imagination surely such a drop would be instantly healed? Or might it be that we currently have a very finely balanced trade off around antarctica and every year with increased ocean heat content brings us closer to the point that this balance shifts?

 

Of course further alterations to the climate down there could prove just as destructive as they currently prove nurturing to the sea ice?

Increased ice losses from Antarctica detected by CryoSat-2

 

Abstract

We use 3 years of Cryosat-2 radar altimeter data to develop the first comprehensive assessment of Antarctic ice sheet elevation change. This new data set provides near-continuous (96%) coverage of the entire continent, extending to within 215 km of the South Pole and leading to a fivefold increase in the sampling of coastal regions where the vast majority of all ice losses occur. Between 2010 and 2013, West Antarctica, East Antarctica, and the Antarctic Peninsula changed in mass by −134 ± 27, −3 ± 36, and −23 ± 18 Gt yr^−1, respectively. In West Antarctica, signals of imbalance are present in areas that were poorly surveyed by past missions, contributing additional losses that bring altimeter observations closer to estimates based on other geodetic techniques. However, the average rate of ice thinning in West Antarctica has also continued to rise, and mass losses from this sector are now 31% greater than over the period 2005–2010.

[Gray-Wolf]

For west Ant this is only the beginning , which is worrying seeing as it currently only takes five years to see a 33% increase? What will the 2010 to 2015 show us? With the P.I.G. outlet about to push back from the current bottleneck we should expect 2015 to 2020 to take an even bigger leap up?

Oh deary me!

 

Has Antarctic sea ice expansion been overestimated?

 

New research suggests that Antarctic sea ice may not be expanding as fast as previously thought. A team of scientists say much of the increase measured for Southern Hemisphere sea ice could be due to a processing error in the satellite data. The findings are published today in The Cryosphere, a journal of the European Geosciences Union (EGU).

Bill Illis says:July 22, 2014 at 9:13 amThe Anatarctic sea ice has extended right past the South Sandwich Islands. Real images tell the story. Yesterday’s Modis pics.

"The South Sandwich Islands are much colder than South Georgia, being farther south and more exposed to cold outbreaks from the Antarctic continent. They are also surrounded by sea ice from the middle of May to late November (even longer at their southern end)"

You know that's exactly what I thought when I posted that. There really is no limit to the length these scientists will not go to maintain the fantasy of AGW. It's as well there are enlightened souls like your good self who see through this deception and destroy this fragile 'truth' with stunning scientific revelations.

Anyway record high for today down there.

 

If I allow for 1,400,000 'adjustment' will be equal to 1995.

I read 

 

""Well, one news article (sorry, I lost track of which) cite Comiso that he believes that most of the trend is real, even once the processing is redone with the best files through the whole period""

 

Its funny even the DMI data is now questionable. Will we see the Arctic data being put under the same scrutiny ?

either I am reading this wrong or you are but the value posted is below the 1981-2010 mean which is the dotted line in the middle not above?

You have the global sea ice chart there CM.
