Revealed: Antarctic ice growing, not shrinking

Revealed: Antarctic ice growing, not shrinking

What??? No way!

Extensive melting of Antarctic ice sheets would be required to raise sea levels substantially, and ice is melting in parts of west Antarctica. The destabilisation of the Wilkins ice shelf generated international headlines this month.

However, the picture is very different in east Antarctica, which includes the territory claimed by Australia.

East Antarctica is four times the size of west Antarctica and parts of it are cooling. The Scientific Committee on Antarctic Research report prepared for last week's meeting of Antarctic Treaty nations in Washington noted the South Pole had shown "significant cooling in recent decades".


Funny how we only hear the 'negative' stuff about the environment. Ice shelves collapsing, and stuff like that. Info like this is just skipped over.

Why? I have one word for you. Control.

Hi Mike!

I agree, the media in general is pretty lame, although perhaps this article included. In an interview published online the day before the "The Australian" article's date:

[Q:]HOW GREAT IS THE THREAT FROM ICE SHEETS MELTING?

[Ian Allison]:"I think it is now unequivocal that warming of the world is occurring and I think the last IPCC (Intergovernmental Panel on Climate Change) conclusively showed that a major cause of warming is greenhouse gas emissions from mankind.

We now know that the ice sheets are contributing to sea level rise and for the Arctic, at least, this is because the warming of this region is much greater than in other places on Earth.

We also know that glaciers in mountain areas are undergoing a very rapid retreat and they're a major contributor of sea level rise, too....

Problem is, the arctic ice cap is mostly floating.... It melts, and the sea level stays the same.

Try it. Take a glass of water, and throw a few ice cubes in it. They melt the level stays the same. Very simple science.

BTW, the Arctic icecap is on track to be bigger this summer than last...

Just for kicks, 1959, North Pole, no ice

The earth has constantly been in flux. Long before we humans walked, and long after. Sure we are a variable in the equation, but I think time will show us to be much smaller that some (Ian Allison) will have you believe.

Anthropomorphic Global Warming is a creative way to sway power and money.

I guess my point is that the orig article was written to heavily imply that sea level rise, and its extent, are in doubt. It uses only three sentences (in the entire article) from this scientist to support the upcoming studies finding.

And yet, the same guy ssentially gives an interview the day before, where he is quoted in paragraphs, affirming his belief that the sea level is rising due to global warming's effect on melting glaciers (he expresses some uncertainty about the ultimate magnitude to sea level rise due to ever-evolving understanding of glacier dynamics, which seems reasonable).

The Australian article was poorly written and, in my opinion, intended to mislead. That was all I was pointing out.

Also, Allison is clearly referring to land-based ice sheets and not sea ice. I'm sure he's familiar with the principle of buoyancy as well.


Cheers,

The Arctic is anything but land based....

Less ice, more ice, it really doesn't matter if we (humans) aren't the cause. That is the question.

"The Arctic is anything but land based...."Greenland and her ice sheets say hello! So do Northern Alaska, Canada, Russia, etc.

Man it's late...time for bed.

Antarctica says hello too.... Nature is a funny thing... Warmer here, colder there. Yin and yang.

What about no ice at the North Pole in '59?

The icepack on the north pole is bigger than the previous two years at the same time....

The sun has active phases and inactive phases....

There has been more snow at my house in the last year than I can remember....

The Earth was even warmer in the middle ages...

The Global temp has NEVER been static.

or incase there are too many words in this article

"The falling away of Antarctic ice shelves does not, in itself, raise sea levels, since the ice was already floating in the sea. But such coastal tables of ice usually hold back glaciers, and when they disintegrate that land ice will often flow more quickly into the sea, contributing to sea-level rise."

I didn't realize that was you, I originally thought the first anony post was by some random internet dude.

My sole intent was to focus on the article and its shoddy journalism, regardless what it may or may not imply. It was clearly written with an agenda in mind, but veiled with the false air of fact-based. I didn't see 'editorial' in the title.

I spend 3 minutes googling Ian Allison to find that interview. It was given at the same time he was interviewed by 'The Australian' columnist. Also, another red flag is the very short snippets of quotes.

I only posted anything because that article is not something I would refer to as an example of any gripe I have with the media in general. That article is what is wrong with a lot of the media.

I'd say the same thing if it was poorly written to imply that global warming was unequivocally going to doom us all.

I believe global warming is primarily caused by human-based emissions. I believe because the evidence is strong....not absolute (but nothing is absolute, as Newton was technically wrong about the universe, and yet his principles are still taught today because they work) but strong indeed....our understanding of climate, the underlying physical processes/forcings are strong...not complete, but strong...lots of people believe as such too. Also, lots of people don't and lots of people are unsure. That's fine with me.

A picture of a sub at the north pole in 1958 is conclusive of nothing by itself. The earth, it's climate, the sun are all dynamic things. No one disputes this. No one.

I enjoy chatting about this; it's fun and forces me to spend a little time reading about the climate.

The sun pumps a tremendous amount of energy into our planet... Hypothetically, what would happen if it stepped up its output even just a tiny bit?

Do I think that we have no affect on the earth? Of course not. I just think it is much smaller that some would have us believe. I think nature is being exploited to push an agenda.

Got to hit the sack, but take a peek at this...
