PIOMAS for April came in and is still record low and in the 2 sigma band as it has been all winter. If we lose a similar amount of ice to that of 2010 or 2012 we will have less than 1,000km3 left in the water by September........
Then we have 'cycles'. 2007 was our first shocker of a low. 5 years later came an even bigger shocker. We are 5 years on from that record low year.
in 07' we were told the 'Perfect melt Storm' synoptic turned up every 10 to 20 years with the last 2 before 07' favouring the 10 year period ( 2 times the 5 year events?).
With long range forecasts putting High Pressure in charge through the rest of May and all of June across the basin we could not be facing a worse start to the melt season this year!!!

And we'll find out (at last) what will happen ... or not. And Sig will be a happy man. More samples are always good ... except maybe in Russian roulette.

That was a 'mean' thing to say.

I am in NZ at the moment, and went and looked at the Franz Josef glacier.
All the articles I read here suggest it is still retreating, but I am sure I read somewhere that that is not the case.
Is there an authoritative source on which glaciers are retreating/advancing?

As with everywhere else precipitation events over South Island have been increasing in intensity so 'feeding' the glacier at source. of course unstable glaciers can also push their snout forward if flow rates accelerate. Such surges plough away the terminal moraine and so make the recent behaviour harder to discern?
Back to the Arctic. The coming week looks like the first 'high loss' week of this years melt season. Areas that saw heavy snowfall will begin to turn slushy grey on the visible sat images as melt ponds begin to form in earnest.

Thanks Ratty
Problem is, as the article points out, that glaciers have two primary inputs: temperature and precipitation.
It then takes a decade or two for the results to be apparent at the snout.
The comment about retreat restarting follows from their AGW viewpoint.

Temps of 80f+ widely across Siberia today? These would be exceptional in high summer but how the hell can such temps be attained when there is still ice in the Ocean and snow on the permafrost? It's almost as though there's a blanket of a super GHG gas laying over the region? (LOL)
