Default West Antarctic ice sheet - collapsing?


"
The massive west Antarctic ice sheet, previously assumed to be stable,
is starting to collapse, scientists warned on Tuesday
"

New Scientist article - link below:

Any comments on this? Too early to say for certain,
but this is obviously not good news.

Obviously?

If it is posible to start colonising the continent it means good news
does it not.

What is obviously bad news is that we have millions of people dying of
illnesses that can be cured fairly easily on other parts of the planet
.......AND ARE NOT LOOKING AFTER THEM BETTER!

So the need for another continent to live on is not great at first
sight. However if the dead are to be resurrected or people from Venus
are to be welcomed....

How much research has been done investigating the aquifers in the area
and how much they might expand when the ice clears.

It is well known that before sea water levels can rise all the other
aquifers will have to be fully replenished. By all accounts (anecdotal
stuff of course) the storms the so called experts say global warming
will cause will take care of that.

You do know that such a solution has been factored into the equations
they use?

Please do provide a citation that all aquifers have to be fully
replenished before sea level can rise. Observations show that global
sea level has risen over the past century, yet aquifer levels have
been dropping.

The previous post I believe is misguided.

Sea levels are of course rising at 2.56 mm/year.

However, I was suprised to see that aquifier depletion could
acount for as much as 20% (0.5mm/year) of the observed rise.

IPCC lists anthropocentric factors as 'min' and 'max',
And other factors seem to balance 'groundwater mining',
though not exactly inspiring confidence in the numbers.

Given that ground water use grows with population,
seems likely that we are at 0.5mm/year and growing
for aquifier contribution to sea level rise.
