Now that the constraining and insulating ring of ground ice around Antarctica is going, going, gone… add in a lot of fresh surface melt that FLOWS DOWN to refreeze (EXPAND) taking away more cold from the base and forcing the glaciers to accelerate more each year (thats accelerate not just move). Double the number of melt days each year and climbing.
So we have twice the lateral pressure over twice the time period with twice the heat thats 2 x 2 x 2 = 8 times change over time. Then feel what happens when the first really big chunk of ice (say 100k by 1k) falls into off the land into a deep ocean, (that wave will ruin the east coast of Australia evidenced in sediments in the North Western valleys behind Newcastle NSW etc.) Such a big splash and a big shake, may trigger other actions.

Add in the once frozen methane now bubbling up from the ocean floor……. 25 times worse than Co2 and lots of it.

And through in another billion people all wanting a shiny new car…

Norm,
Can someone explain me why raising the temperature of Antarctica from say -50 to -45 would have any effect on ice melt?

“Such a loss of Arctic sea ice cover has recently been assessed to set in motion powerful climate feedbacks which will have an impact far beyond the Arctic itself,” he said.

He added: “This could lead to flooding affecting one-quarter of the world’s population, substantial increases in greenhouse gas emissions from massive carbon pools and extreme global weather changes.”

Critical thinking required: melting floating ice will not raise sea level at all. It’s already in the ocean.

The North Pole will turn into an open sea during summer within a decade, according to data released Wednesday by a team of explorers who trekked through the Arctic for three months.

The Catlin Arctic Survey team, led by explorer Pen Hadow, measured the thickness of the ice as it sledged and hiked through the northern part of the Beaufort Sea earlier this year during a research project.

Their findings show that most of the ice in the region is first-year ice that is only around 1.8 metres deep and will melt next summer. The region has traditionally contained thicker multiyear ice, which does not melt as rapidly.

“With a larger part of the region now first-year ice, it is clearly more vulnerable,” said Professor Peter Wadhams, part of the Polar Ocean Physics Group at the University of Cambridge, which analyzed the data.

“The area is now more likely to become open water each summer, bringing forward the potential date when the summer sea ice will be completely gone.”

Wadhams said the Catlin Arctic Survey data supports the new consensus that the Arctic will be ice-free in summer within 20 years, and that much of the decrease will happen within 10 years.

Martin Sommerkorn of the World Wildlife Fund said the Arctic sea holds a central position in the Earth’s climate system.

“Such a loss of Arctic sea ice cover has recently been assessed to set in motion powerful climate feedbacks which will have an impact far beyond the Arctic itself,” he said.

He added: “This could lead to flooding affecting one-quarter of the world’s population, substantial increases in greenhouse gas emissions from massive carbon pools and extreme global weather changes.”

Global warming has raised the stakes in the scramble for sovereignty in the Arctic because shrinking polar ice could someday open resource development and new shipping lanes.

The rapid melting of ice has raised speculation that the Northwest Passage linking the Atlantic and Pacific oceans could one day become a regular shipping lane.

The results come as negotiators prepare to meet in Copenhagen in December to draft a global climate pact.
