(link that always goes to last page on the thread)
I have not been following the debate, but I will start a fresh clean thread.
As ever the scientific thing is to first define the problem.

Sea level rise is not a problem if you are in a boat, as it just floats on top of the sea
Similarly for islands created out of coral growth
If your house is getting flooded, then somewhere nearby in the sea coral will be growing upwards to the current sea level
and will in decades trap sand and become an island.

So the problems to do with the sea are
#2 coastal erosion .. a natural process that has always happens over millions of years
Land erodes and then likely rebuilds up further down the coast, increasing its land area

And #1 Land flooding
When people are worried about sea-level rise, what they are really worried about is Land Flooding
That can often be mitigated by drainage and building barriers against the sea ..like they do in Holland.
====================

And when we talk about Sea Level
are we talking about as measure from space
..or as measured from a line on a rock ?

Cos the land the rock is on might be rising or falling independently of the sea over geological time.
There is no use panicking about water if the land is falling so fast, that barrier building won't work.
Loads of British towns have been moved further inland or further out to sea over the centuries as geography changed.

I have great sympathy for Bangladeshis living on low lying land.

I firstly wish that their government would manage things better
by #1 Discouraging people from having so many children
... #2 Managing land better
eg by swapping high up land that big farmers are just using for farming
with lower vulnerable land that poor people have houses on.

I have been to lots of places in the world where people live on stilt housing
and don't expect their houses to last more than 30 years
They just keep rebuilding their houses
and always stay dry. and often protected from mosquitoes co of the sea.
