It's another " Clean Air Act" is it not??? Back then we 'cleaned up our act to preserve surface air quality only to exacerbate global warming and it seems we are doing the same again. When we note something that we have caused that will directly impact 'human life' we act without thinking about what it has shielded us from.....silly old humans eh?

Doomwolfe give it a rest for once. When we get to the stage of zero pollutions we'll still be doing something wrong. Someone someone where will jump up and down alarming you've got to learn to chill out. Remember you killed us 500000000 times already and we're still alive and err so is planet.

Doomwolfe....

I can't change the reports but I may be a tad selective in my choices! As comedians tend towards depressive mindsets when off the stage I tend towards euphoria when away from the boards Pit.........

And still Wilkins continues to fall apart.....shame the sea ice isn't thick enough to hold it in place eh?

Do check out the animation.

So not just me then?

When a plant is dying it may put on the most spectacular display so 'swan songs' may be many and varied through nature (including dying stars).

These few years of 'ice extent growth' will prove to be Antarctica's 'Swan Song' and much the same as the single year ice debate ,insofar as extents were concerned, that raged through late winter.

Meanwhile we will still see massive net losses in ice mass from the continent and the death of Wilkins next southern summer. What can you say to allow folk to see?

Except for the fact that there is a massive growth of the ice.

Where bluecon? If we take all the little slivers of extra ice beyond the 'normal' and stick them around the peninsula do you think they'll be any left over?

Yeah - about 1.5million square kilometres

and rising!!!!

So now we even have studies on ice cover disgareeing with each other. The Internet is great in that you can try and research something you don't agree with but at the same time it's such a potential source of bull it creates most of the disinformation you don't agree with in the first place - perpetual motion has been discovered....

Apologies - 1.3m sq km - don't want to appear to be exaggerating

any reasons for the above? shouldn't we be rapidly expanding at this time of year?

Seems a bit strange that doesn't it. Either a data error or maybe a chunk of ice has broken off?

I would say probably a bit of political "correction".

It can't grow outwards indefinitely in the southern ocean current, it has to thicken as well as grow in extent. So the ice edge wobbles to and fro. It's still growing, as the animation below shows.


if it ain't linear, it's probably due to "weather"

Thank you Chris, and so to the point. Is the circumpolar wind becoming a 'limiting' factor as well as a causal factor for ice growth? if the ice is favouring growing in the lee of features that 'protect' that bit of open water from the worst of the circumpolar wind/current then any step beyond could end in disaster as the 'belt' of wind/currents erodes the ice.

I'm doing some work with the AAO for an aussie LRF this winter. The is an indicator of the strength of the polar low and position of the highs/lows. Lately the AAO has indicated a strong polar low and winds but you can see occasions that roughly coorelate - end of April, etc - with a drop in the AAO. It might be something...

[Gray-Wolf]

For 15 yrs or so years folk have been noting the changes in 'regimes' down there.

Be it the increase in circumpolar winds or increase in snowfall over the peninsula. Maybe there is a 'core change' taking place in the normal weather patterns as the global changes impose upon it. If anything were to interrupt the Katabatic winds from the centre of Antarctica over the southern summer (allowing warmer waters into the coasts) then there would be trouble!

How come the anomoly doesn't read zero here?

Wilkins continues to disintegrate. Now hanging by it's last little ice bridge before the final collapse. Apparently the 'thin' sea ice and warm water under the shelf isn't helping.

Guy's, guy's. You stopped updating me on how far above 'normal ' ice levels were down there so I had to look myself and .....well you can see for yourself (above). Seeing as Antarctica is having one of the coldest winters since '88 I'd have expected more.

Sooooo, what gives? (apart from Wilkins that is ).
