A new study has found that the Antarctic Ice Sheet began melting about 5,000 years earlier than previously thought coming out of the last ice age, and that shrinkage of the vast ice sheet accelerated during eight distinct episodes, causing rapid sea level rise. Read full article

'sea level rose about 50 feet in just 350 years ... amplified by physical processes.'

Right, this gives us the ballpark rise that we might expect. The 'physical processes' will be enhanced by those caused by industrialisation, so this is a 'bottom-end' estimate.
Heaven help the world's coastal cities.

“The researchers suspect that a feedback mechanism may have accelerated the melting, possibly by changing ocean circulation that brought warmer water to the Antarctic subsurface,”

This is what professional oceanographers have witnessed below the recent ice melt that is panicking some people all over the planet.

It just shows that man is so pig-headed when they think this is the first time that warm water “welled up from the ocean floor”, it isn’t and it most likely will not be the last.

NASA has studiously turned their backs on another group of scientists with objective evidence that the atmosphere over the Antarctic is NOT warming but COOLING, despite all the man made CO2 whatever.

Never mind, when the Sun turns into a red dwarf (a misnomer if ever there was one) and reaches out to touch and engulf our planet in only 4.3 billion years there will be no water and of course no people, because if they have not left the planet at least 1.5 billion years before then, they will die anyway.

In the meantime it would seen that human life under the sea will need to get a move on.
