Antarctic Ice Sheet Growing?

How long until it hits australia/south america/NZ at this rate?
Remember, there were no nuclear weapons before women were allowed to vote.
The penguins are suffering this year because of the strange behaviour down there.
Every year i hear "Global Warming is Occuring" and "The icecaps are melting", but then i also hear "The icecaps are expanding! another ice age is coming!"
-make up your scientific minds already-. You're worse than the local weatherperson.
Now.. do i need this fleece sweater or not?!
It's shrinking as well. The iceberg reported in the link was enough to cause a concern for shipping lanes, at the time. I don't know whatever happened to it.
Also, the only thing that anyone involved in the science of the whole thing is that global warming will have an effect on the climate. Its anybody's guess, really. I could mean that in the sort term temperatures rise a little allowing snow to fall in places in which it used to be too cold to snow in large quantities resulting in more sun light being reflected back. Who knows? The problem as I see it is not climate change itself. The climate will change with or without our pollution. The problem it seems is our unwillingness to deal with the fact that we will face problems. Again, contingency is seen as a waste, and disaster is seen as the failure of those who were supposed to have the contingency that was so wasteful. Shit happens. Seas rise, lakes dry up, rocks fall from the sky and stars explode.
None of the experts think global warming can effect the ice sheets, yet. These ice sheets are huge. The West Antarctic Ice Sheet is over 4km thick. The bottom of the ice will not feel global warming for hundereds of years.
We'll all be dead before global warming has any real effect on these ice sheets. So don't worry be happy?

Global warming is incredibly complex - it does not mean that everything is the same except that the temperature is a few degrees warmer everywhere.
Specifically, there were some predictions that GLOBAL warming would cause LOCAL cooling and increased snowfall. The reason is simple - increased temperatures means increased evaporation and increased clouds. Some early naive rebuttals thought that the cloud cover would increase globally, reducing the amount of sunlight and throttling global warming, but more sophisticated models (and experience) shows that there will be stronger "high pressure bubbles" that keep the skies clear of all clouds for prolonged periods. Read: expect more droughts, and more severe droughts.
In the high latitudes, there's been relatively little cloud cover or snowfall because cold air can't hold much moisture. I live in Colorado and can definitely see that here - we get heavy snow in the fall and spring, but in deep winter a heavy snowfall will be 2-3 inches instead of 9-12 inches. Global warming means that upper atmosphere warms up enough to sustain more clouds and more moisture, so you'll see local temperature drop and increased snowfall.
I saw a map of predicted changes over North America a while back. There were small pockets over SE Alaska and coastal British Columbia (IIRC) that showed modest temperature drops, but most of the rest of the continent showed larger temperature increases. In the dustbowl states the temperature was much higher.
Bottom line - the real question here is if this was predicted by the current global warming models.

As you point out unless something is done about the problem then the effects of global warming could be disastrous, but the causal link that using aerosols (with cfc's)(or any one of a hundred atmospheric no-no's) is not clear in most peoples heads and hence convincing them that the massive spend is necessary is going to be difficult. I can give you a very simple example in London there is a flood defence system which is basically a system of barriers that can be swung up or down to protect London against high tides even though the barriers have been raised several times to protect the city against floods. The money spent on this is still considered by some to be a waste.

If the ice were melting you'd complain about that. The ice is getting thicker, you complain about that. There is no pleasing you.
I just finished a graduate-level Physics of the Weather class. The strange thing about global warming vs. cooling is that both sides are right. It depends on which scale you look at. For example, the long-term trend is towards warming while the short-term trend is towards cooling. You look at the graph of (estimated, very estimated) temp vs time, and it looks somewhat like a sine wave with a period of 10,000 years with a superimposed sine wave with a period of 400 years. In other words, it's a graph of something with changes occuring at different frequencies. For any EE that knows the slightest thing about FFT's, it's obvious. Apparently for your average journalist or weatherman, the concept is above them. When you mention changes with a complicated system, you need to include the scale. Are you talking about warming over a 100 period or our overall cooling trend?
The polar ice caps both north and south are getting thicker and bigger.Just like the few half-brain cell types who still believe in global warming.Come on huge climatic changes occured long before man or woman for that matter set foot on our lovely little planet.Catch on the earth is a living, breathing,ever changing eco planet thing.GROW-UP learn to read the signs that gaia gives and adapt!

"Present them with a very current, very REAL problem that affects us today, and their true ignorance wouldn't be hard to spot. "
...their ratings would drop right after that sentence.
-So we should stop researching problems that might arrise in the future? Ok, lets just sit back, pollute our skies, use up all the oil, and then when we can't drive our cars, or breathe without an environment suit, THEN we'll start thinking of what to do...
"First of all, the only time we hear about "Global Warming" is during the summer"
-The only reason we hear about it during the summer is because the news stations wouldn't air it during the winter... no one would believe it. "Today's high will be around 15 degrees... next up, an interview with a top scientist in the research of global warming"
"I propose we organize a similar movement that acknowledges the global cooling (Winter, for us laypersons) that is always occuring SOMEWHERE in the world"
-I think you have your definiton of Global wrong. You say that global warming and global cooling is always happening SOMEWHERE in the world... but that's not "Global"... it's "Local".
If you did research the findings that the scientists have brought in, it shows the effects of green-house gasses in the air (CO2 and other compounds), and it's effect on our (here's that word again) Global climate. After drilling into the ice caps and measuring the concentration of the CO2 levels in the past, they matched up the rise and fall of CO2, and mapped it against the ice ages... and found how they match up. If you couldn't guess, the more CO2, the hotter it is. (Less CO2, the colder it is). Guess what... the CO2 levels are on the rise (the highest they've EVER been... besides when earth was forming)... and this is how they justify the global warming...
That's it buddy, feed that troll.

This one gets the science a little better.
Too bad no one is reading this low.

Summary: The majority of the Anarctic continent is isolated from the rest of the world when it comes to weather patterns. Most research stations aren't in the isolated part, they are in the most northerly portions of the continent. They are warming. The isolated part of Antarctica is cooling. It's basically a re-analysis of existing data that has resulted in this conclusion.
