The perfect job opportunity:

SWIMMING INSTRUCTOR IN TUVALU

Pays 10 coconuts a week!

I'm living on the frontline where this scam is rampant. Thank you Labor.

"and there is some suggestion that sea-level rise is declining"

Only on denialist blogs. The research literature is clear sea levels are rising.

"If Tuvalu 'sits just two meters above sea level' then on my calculations it will, all other things being equal, 'disappear' about 2680, unless there is an astonishing rise in sea levels."

What an astonishingly ignorant statement. The problem is not that the island will rapidly drift out of sight underwater, but that the island will become uninhabitable because of the flooding that will occur during storms when waves are much higher than the average sea level.

But you are correct, these people are not climate refugees. They may come later.

Tide goes out - the sea level drops.

Next question.

That is of no help at all if your house has been flooded or your crop fields are inundated with sea water.

In fact it is a silly thing to write.

Hasbeen old mate.
Fact 1# The water that is melting the ice in question, is a measured 4C!
2# And at least 5C higher than the previous subzero norm for that region?
Hence the more rapid ice melt?
You may be correct, that a new ice age may be coming, and possible due to seriously increased global convection, and subzero upper atmosphere mixing downward as never before; due to climate change, creating just what you have postulated?
That said old mate, the ocean sized body of water exists, and is currently only contained by a comparatively thin, now very dubious ice wall.
And the more rapid melting than previously postulated, by the so called doomsayers, is a worry that simply can't be discounted, or burying the head somewhere warm and comfortable!
However, I'm not all that worried.
I'll be alright in my mountain home.
And if the major capitals are largely destroyed virtually overnight?
Well, there be far less traffic on the roads, to worry about, and the deep harbors, will be three metres deeper.
The fact is, when this body of water ever does escape, then it's just not we who'll be affected by a three metre sea level rise, in a single afternoon, but the entire world!
Put these two things together.
The huge body of marginally dammed water exists, and the ice preventing it from adding to sea levels, is still rapidly melting! When it is released, seas levels would then rise overnight, around the world, by around an averaged three metres!
And the temperature of the ocean waters involved in the melt down, is an averaged 4C!
Or around 5C higher than a previous subzero normal?
You can remain on the coast and give swimming lessons if you like?
But wiser men, will take what they can get right now, and head for the hills, where property is currently, much cheaper, and more abundant!
Cheers Rhrosty.
