I'm wondering if this is purely a byproduct of GW or why it should be
accelerating - given Antarctic SST's fairly stable etc.

Please note I am asking the question rather than trying to prove a point

That piece featured on the BBC news yesterday. I cannot believe GW is not
a large contributory factor.

I think the Antarctic SST's are stable - or even have been lower than normal
- because the excess melting of of the land ice has provided a larger supply
of cold, fresh water than normal.

Graham, am I correct to say that the ocean flow round Antartica is largely
decoupled from the rest of the planet?

Oh here we go again when its colder its AGW and when its warmer it AGW

The BBC jump on this stuff with such eager glee that facts and eventual
retractions get left by the wayside of western guilt and angst.

If Brian had read a little further he would have seen that the
research was not exclusive to the BBC. It was just that the scientists
had sent the BBC a press release. In fact " The work by British
scientists appears in Geophysical Research Letters."

Judging from the map, Pine Island is further north than most of
Antarctica so it is liable to start melting first. I think the
conundrum of why the SST has remained the same but the glacier is
melting, is that the sea surface there is mostly melted water from the
ice shelves. that makes it cold (0C) and fresh, so it will float over
the saltier ocean water which is warming because of the global
increase in the greenhouse effect. It is this deeper warm salty water
which is undercutting the glacier. OTOH, it could be increased
condensation from warmer wetter air that is doing the damage.

I would just say to Lawrence, it is not about the melting glacier
proving global warming is happening. It is how is global warming
melting the glacier when that region does not seem to be warming?

Not something I know too much about but, after some googling, I'd say no.
For instance, see

Thanks Graham,

quoteThe Antarctic Circumpolar Current is an important feature of the
ocean's deep circulation because it transports deep and intermediate water
between the Atlantic, Indian, and Pacific Ocean, and because it contributes
to the deep circulation in all basins. /quote

So, what goes on in the Antarctic *is* important for the planet. Paul, Is
this the explanation you were hoping Lawarence would have provided? OK we
can argue about it but I am not an expert on complicated interactions
between ocean and atmosphere, which is why I have kept quiet.
Also, I would certainly never go as far to say that - just because the
Antartic is stable or getting colder it means GW is going away, it is far
more complex than that.

Cheers,

Will
