Major Antarctic glacier is 'past its tipping point' - catastrophe now cannot be avoided

Is Antartica going to be the global warming catastrophe? The sea level rising by 24cms? Most towns on the coast wont survive. If this is a conspiracy then we better take note of it. We may not see the 24 cms rise but our children may face it. SO what can be done? Is global warming fake? Or are we ignorant of this?

A major Antarctic glacier has passed its tipping point, according to a new modelling study. After losing increasing amounts of ice over the past decades, it is poised to collapse in a catastrophe that could raise global sea levels by 24 centimetres.

Pine Island glacier (PIG) is one of many at the fringes of the West Antarctic ice sheet. In 2004, satellite observations showed that it had started to thin, and that ice was flowing into the Amundsen Sea 25 per cent faster than it had 30 years before.

Now, the first study to model changes in the ice sheet in three dimensions shows that PIG has probably passed a critical "tipping point" and is irreversibly on track to lose 50 per cent of its ice in as little as 100 years, significantly raising global sea levels.

Or we could just move 9 1/2 inches more above current sea level. Catastrophe avoided.

So roughly 30 years of data and they have come up with this....

IF they were working off 1000 years of data it MIGHT become believable.

What if we dump large amounts of liquid nitrogen on it???
Nitrogen is eco friendly.

Neat. Good source.

West Antarctic ice sheet is thickening

www.newscientist.com...

The discovery comes a few days after another team claimed that most of Antarctica is cooling down, not warming up, a conclusion that conflicts with "greenhouse" climate models. Both studies show that despite decades of research, Antarctic climate patterns remain poorly understood.

He also notes that any human-induced climate change is likely to take a long time to affect the ice sheet. The ice is a kilometre thick, so "it would take thousands of years for surface temperature to affect the bed of the ice stream," he told New Scientist.

I agree with these sentiments.

These two quotes are extremely accurate.

Give that guy a raise lol.

Does anyone have any theories as to why the google earth image of Antarctica has a large chunk of data in the form of a circle and attached line that is missing?

Your goalposts sure are mobile, aren't they?

30 years of research conducted by hundreds of researches = several thousand people-years worth of research.

Yeah , that part of the camera is broken. there is a space bug on the lens, that is actually what Antarctica looks like in that area, Your eyes are playin tricks on you , it looks fine to me....... or maybe that is where the south pole telescope is..

Will this one float past Australia too, Will it cause a tsunami, weight displacement?

It seems like another reversal in GW everyday.

I always thought that it's like that because there is no data for that part of Antarctica as the satellites don't fly over it. As I remember, it's the same at the North Pole, too.

Antarctica is melting!

Antarctica's ice sheet is growing!

Antarctica's ice shelf is collapsing!

Antarctica is getting colder!

Antarctica is getting warmer!

Sorry, I'm not buying it. Antarctica is probably doing something, but I'd be willing to bet good money it will be doing something else tomorrow.

Octomom: yes, the satellites do not orbit the poles and thus the resolution of them is severely limited. They have to be moving to maintain orbit, and in order to remain stationary relative to the surface and get precise data, they cannot be at the poles.

That study is so full of fearmongering bogus its ridiculous.

The antarctic icesheet has been growing.

Well, I learned a few weeks ago, the magnetic north pole is like taking a cab t Siberia so the south pole maybe drifting to ?

It might explain different observations ???
