Antarctic Sea Ice At Record New High

Scientifically meaningless.

As I already posted on another thread over here......

 

Hardly!

Since I post the facts from reputable scientific sources, my 'messages' don't really need any improvement. Unlike the unsupported drivel, lies and pseudo-science that you denier cultists post all the time.

The fact that you ignore the scientific facts and obsess over the font size is very telling.

 

So the NSIDC is drivel eh? That will come as quite a surprise to many including you since you posted a link to it.

NSIDC's research and scientific data management activities are supported by NASA, the National Science Foundation (NSF), the National Oceanic and Atmospheric Administration (NOAA), and other federal agencies, through competitive grants and contracts.

BTW, global sea ice is up so posting only about the Arctic is not global.

 

Nope. I didn't say that anything from the NSIDC was 'drivel'. You're once again trying to frame a ridiculous straw-man argument by making stuff up. I said the graph of Antarctic ice extent that you posted, which showed only slight variations, was "scientifically meaningless" in relation to AGW and the extreme ice loss of the "Arctic death spiral". I just explained in post #26 the absurdity of your denier cult propaganda trick of trying to conflate the extreme Arctic ice loss with the minor and temporary expansion of the fringe of sea ice that seasonally surrounds the continent of Antarctica, which is covered by miles thick ice sheets that are losing ice mass and raising sea levels.


These images using satellite-derived sea ice concentration data show average minimum and maximum sea ice during March and September for the Arctic and Antarctic from 1979 to 2000. Seasons are opposite between the Southern and Northern Hemispheres; the South reaches its summer minimum in February, while the North reaches its summer minimum in September. (March is shown for both hemispheres for consistency.)

Almost all of the sea ice that forms during the Antarctic winter melts during the summer. During the winter, up to 18 million square kilometers (6.9 million square miles) of ocean is covered by sea ice, but by the end of summer, only about 3 million square kilometers (1.1 million square miles) of sea ice remain.

You sound and write like you are in high school. BTW, you have not proven that the Antarctic, who's temperature averages well below zero, is loosing ice mass. In fact recent studies say it hasn't.

I made the pertinent statement bold.

LOLOL.....as personal insults go, that one is pretty lame....and ironically hilarious....

Two lies in two sentences. Recent studies say that Antarctica is losing ice mass at increasing rates. I just posted a recent study in post #23. Is it that you didn't read it or that you are simply incapable of understanding it? Try again.

Doubling of Antarctic ice loss revealed by European satellite
Continent shedding 160 billion tonnes a year, CryoSat-2 shows, just days after warning over western ice sheet's collapse
The Guardian
Damian Carrington
19 May 2014
(excerpts)
Antarctica is shedding 160 billion tonnes a year of ice into the ocean, twice the amount of a few years ago, according to new satellite observations. The ice loss is adding to the rising sea levels driven by climate change and even east Antarctica is now losing ice. The new revelations follows the announcement last week that the collapse of the western Antarctica ice sheet has already begun and is unstoppable, although it may take many centuries to complete. Global warming is pushing up sea level by melting the world’s major ice caps and by warming and expanding oceans waters. The loss of the entire western Antarctica ice sheet would eventually cause up to 4 metres (13ft) of sea-level rise, devastating low-lying and coastal areas around the world. The new data, published in journal Geophysical Research Letters, comes from the European Space Agency’s CryoSat-2 satellite, which was launched in 2010. It shows that the western Antarctica ice sheet is where 87% of the lost ice is being shed, with the east Antarctic and the Antarctic peninsula shedding the rest. The data collected from 2010-2013 was compared to that from 2005-2010.

The satellite measures changes in the height of the ice and covers virtually the whole of the frozen continent, far more of than previous altimeter missions. CryoSat-2 collected five times more data than before in the crucial coastal regions where ice losses are concentrated and found key glaciers were losing many metres in height every year. The Pine Island, Thwaites and Smith Glaciers in west Antarctica were losing between 4m and 8m annually. “The increased thinning we have detected in west Antarctica is a worrying development,” said Professor Andrew Shepherd, at the University of Leeds and who led the study. “It adds concrete evidence that dramatic changes are underway in this part of our planet.” Professor David Vaughan, at the British Antarctic Survey and not involved in this research, said: “The increasing contribution of Antarctica to sea-level rise is a global issue, and we need to use every technique available to understand where and how much ice is being lost. Through some very clever technical improvements, [Shepherd’s team] have produced the best maps of Antarctic ice-loss we have ever had. Prediction of the rate of future global sea-level rise must be begin with a thorough understanding of current changes in the ice sheets – this study puts us exactly where we need to be.”

 

You focus on a small area of the Antarctic instead of the whole continent. I hope you realize that the papers that was pulled from suggests that it won't happen, if it happens, for 200 to 900 years. I also hope you realize that West Antarctic has active volcanoes and is on the Pacific Rim of Fire.

 

Hoozier, isn't the west Antarctic Ice already in the water? the article stated thinning ice, I thought that the ice went to the floor of the ocean there. What exactly is it do you supposed they are referring too thinning? BTW, I thought ice melted at 0 degree C? Has this winter exceeded 0 degree C this year? Sorry I'm so skeptical, but I mean, let's call it what it actually is. Oh and one other point, notice how they reference the loss in a few centuries, like they'd be around if they were wrong. LOL.... I love this stuff.

 

To give the alarmist prediction of sea level rise all of West Antarctica would have to melt but that is not likely. Only a few of the glacier basins allegedly could collapse if enough melt from below happens.

 

LOLOL....."200 to 900 years"???.....Antarctica is ALREADY losing ice mass and at increasing rates......from the paper cited in my last post above, which some deniers are apparently having trouble reading....

Antarctica is shedding 160 billion tonnes a year of ice into the ocean, twice the amount of a few years ago, according to new satellite observations. The ice loss is adding to the rising sea levels driven by climate change and even east Antarctica is now losing ice.

Not sure how that is possible when there is more ice today then last year. Huh?

 

The continent of Antarctica, which holds 90% of the Earth's fresh water in the form of ice, is definitely losing ice mass, as many scientific research studies have shown. The loss is currently about 160 billion tonnes a year and the rate of ice loss is increasing.

You are apparently incapable of comprehending the difference between the ice on the continent of Antarctica and the fringe of floating seasonal sea ice that melts almost completely away every southern hemisphere summer.


These images using satellite-derived sea ice concentration data show average minimum and maximum sea ice during March and September for the Arctic and Antarctic from 1979 to 2000.

ok, so tell me where the loss is at, if the ice builds over the winter months and then melts off in the summer months? Me thinks you are confused.

 

LOLOL...as I just said:

Me? hahahahahaha. You make a claim and can't back it up again. S0n get a new career.

Here, if 160 billion tons is what is built up over the winter and 160 billion is what melts in the summer, than again, where is the loss?

 

I don't know in America, but in EU we have made a lot to limit emissions of greenhouse gasses ... some results have to be visible!

 

What are you talking about???

Sea ice builds up and melts seasonally around the fringes of the continent of Antarctica. That has nothing to do with the accelerating ice loss from the ice sheets resting on Antarctica.

Are you really mentally incapable of comprehending those simple facts?

 

The following article shows some of the problems with knowing what is going on.

Well, I'd agree that you definitely have some problems knowing what is going on. The rest of us though are a lot clearer. Perhaps because we don't deny science and reality.

Some earlier research...

Ice Sheet Loss at Both Poles Increasing, Study Finds
NASA
November 29, 2012
PASADENA, Calif. - An international team of experts supported by NASA and the European Space Agency (ESA) has combined data from multiple satellites and aircraft to produce the most comprehensive and accurate assessment to date of ice sheet losses in Greenland and Antarctica and their contributions to sea level rise.

In a landmark study published Thursday in the journal Science, 47 researchers from 26 laboratories report the combined rate of melting for the ice sheets covering Greenland and Antarctica has increased during the last 20 years. Together, these ice sheets are losing more than three times as much ice each year (equivalent to sea level rise of 0.04 inches or 0.95 millimeters) as they were in the 1990s (equivalent to 0.01 inches or 0.27 millimeters). About two-thirds of the loss is coming from Greenland, with the rest from Antarctica.

 

You should come up to date a bit. 2012 was the largest loss yet global sea ice is well above the average now.

 

I'm talking about what you posted:
"Almost all of the sea ice that forms during the Antarctic winter melts during the summer. During the winter, up to 18 million square kilometers (6.9 million square miles) of ocean is covered by sea ice, but by the end of summer, only about 3 million square kilometers (1.1 million square miles) of sea ice remain."

This paragraph you supplied states that, and I quote, "Almost all of the sea ice that forms during the antarctic winter melts during the summer" end quote. so again s0n, if not all of the ice that forms over the winter doesn't melt, then s0n, there is no ice loss. Your post s0n. BTW, if all of the ice does not melt, then that means, drum roll please, the ice is increasing.

oh, and there is no rise in the levels of the ocean since it is all sea water freeze. So, not sure how anyone can make the statement that the sea level is rising when there is no evidence of it. Again, your own post!!!!!

 

Actually the sea is rising as it has, steadily, when it started at the beginning of the Holocene but the CAGW line is that it has accelerated though there is no indication that it has.

 

MOD EDIT - Rule 3 the fringe of floating sea ice around the coastline of Antarctica that grows to a large extent and then melts almost completely away every year, is entirely different from the permanent two mile thick ice sheets that rest on the continent of Antarctica and that are losing ice mass at an increasing rate.

MOD EDIT - Rule 3

Sea level is rising at an increasing rate
NOAA - National Ocean Service
There is strong evidence that global sea level is now rising at an increased rate and will continue to rise during this century. While studies show that sea levels changed little from AD 0 until 1900, sea levels began to climb in the 20th century. The two major causes of global sea-level rise are thermal expansion caused by the warming of the oceans (since water expands as it warms) and the loss of land-based ice (such as glaciers and polar ice caps) due to increased melting. Records and research show that sea level has been steadily rising at a rate of 0.04 to 0.1 inches per year since 1900. This rate may be increasing. Since 1992, new methods of satellite altimetry (the measurement of elevation or altitude) indicate a rate of rise of 0.12 inches per year. This is a significantly larger rate than the sea-level rise averaged over the last several thousand years.

 

So, you're saying now you didn't write what I quoted. So now the big denial. So typical of you. Stand by your post.

WiNnInG and taking names!

 

Nope, wrong again, as usual. I'm saying that you can't seem to understand the basic facts about Antarctica and the difference between the seasonal floating sea ice and the miles thick ice sheets that rest on land.
