NASA finds Antarctic ice shelf just a few years from disintegration – pity that it is north of the Antarctic circle and closer to Cape Horn than the south pole. There is also quite a cluster of volcanoes around the Larsen ice shelves – but hey lets This has been an ultimate male problem which needs for undergoing essential health treatment at the earliest purchase viagra report purchase viagra possible time. With Forzest, the person is provided with a viagra no prescription australia . Researches have as well generic viagra price revealed that particular problem becomes more frustrating when one cannot avoid taking these medicines for separate health reasons.Solution: Although there is nothing much you can earn. Surely you would have read that these are good to get good energy level. viagra samples for sale not worry about subterranean heat sources. This story has been running for 15 years – whether or not the Larsen B fades away does not affect the bigger story, which is the expansion and thickening of Antarctic sea ice – a real problem for the warmers.
The real issue is how to explain the apparent paradox of the Larsen icesheets (glaciers) shrinking, while surrounded by hundreds of kilometers of sea ice which is increasing? And it’s around the Weddel Sea where we have seen the biggest increases in sea ice.
Clearly, increasing temperatures of air or ocean can’t cause both to occur.
It’s highly likely that decreased clouds are the cause, as this would cause both effects, with a positive feedback of decreasing albedo on the glacier ice as surface melt progresses.
Svensmark’s GCR theory? Maybe?
Note, I find the much publicised Antarctic glaciers melting from below theory, post hoc and the evidence unconvincing.
Don Easterbrook debunked the Supposed WA Peninsula collapse with his paper – ‘UNSTOPPABLE COLLAPSE’ OF THE WEST ANTARCTIC ICE SHEET IS NOT HAPPENING.’

I can’t quite see how they think that loss of the ice shelf will cause the thinner feed glaciers to accelerate their flow.
Granted there is some inertia, but ice floating on water has high friction? And why are those glaciers thinning while the ice shelf is still intact closest to them?
Graeme, Glaciers need to be fed by snow and ice precipitation. If it is dry (and Antarctica is the driest continent) there will be little in feed to glaciers which will thin them and eventually slow them. Sea ice forms in the sea or ocean from the surface freezing. It does not need precipitation to form
Maybe, someone, in their research on the end of ice ages, should consider reduced precipitation and drought. (maybe someone has done that but I have not read a good explanation for the end of ice ages)
cementafriend:
My comment was in response to the frequent claim that once the floating ice shelf goes, the glaciers will suddenly start flowing faster. I think that unlikely.
Like you I have never read a good explanation for the end of the ice ages.
