Yes, the exceptional warming of the Peninsula has certainly been noted well back in the last century and the increased melt of the Larsen shelfs lead to the odd collapse of B'.
It is not this calve that is of interest ( though it will be magnificent?) but what happens to the rest of the shelf there after?
If the impacts of the ozone hole has brought as much damage as some scientists fear then we may well see further collapse once the support of the calved section is removed?
Should the rest of the shelf begin to do a B' on us then we will know that the increased circumpolars (that the Ozone hole drove) will have resulted in increased melt , year round ( as measured by the teams there) across the shelf ( from increased occurrence of Fohn winds streaming off the peaks behind) facilitating the freeze thaw wedges that we saw devastate B'
So if we see such we will know that it is a man made event and can blame the fridge freezers of our youth ( if you are of a similar age to myself and others posting on here?).

I suspect on these timescales....none of us will live long enough to find out??

Yes, problem is that ice shelves break off for two reasons. One is they melt, get thin and snap. Two is they get pushed so far to sea that the ice snaps simply from the bulk movement of the shelf. Larsen is way the heck out there and its been warm in that particular area of the Antarctic.

Even the experts on this don't see a AGW link....it's a natural process, enjoy it, I'm sure they'll be some amazing footage etc, but certainly no Unnatural consequences

Well we'll need to wait for the thing to go first! As I say the full moons might provide the Ooomph to shear off the last km in rapid order ( with the movement of the rest of the shear bearing down on that section?) so we might not have long to wait. The rest of the shelf collapses like domino's and I'm claiming man made from Ozone hole forcings!

Sounds fair!! You'll have to write a paper though!!

Graywolf: You need to do a bit more research in regards to the Ozone hole, cause and effect.
One would hope that you realize that the Ozone hole expands and contracts over Antarctica on an annual basis?
Also, there has ALWAYS been an Ozone hole over Antarctica.

Graywolf, if you don't mind, could you please explain (this is an honest question) how the southern ozone hole "drives the circumpolars" and thus is exacerbating the current state of the Larsen ice shelf? Thanks in advance...

As I've posted elsewhere this calve , if all we see is a chunk of ice a quarter the size of wales break of then i'm with it. If we see there after a domino like collapse of 2/3rds more of the shelf then I will claim AGW forcing via Fohn winds streaming of the upland Peninsula since the formation of the Ozone hole ( and the hydraulic fracturing fracturing of the body of the shelf , Larsen B'esque, thereafter.
Big calve? It's what ice shelfs do over time.
Partial/full collapse of the remaining shelf? AGW.
