Sealevels rise significantly in the 20th century!

What would the seagoing nations of the world, and their cities citizens, do?

Move the cities inland perhaps?

How significantly is reasonable?
 
Move the cities inland. Yeah, good for the nations that have 'inland' spaces. What do we archipelago-dwelling people do?
 
Or those of us who live in deserterfied countrys.
Wouldn't the sea cause them to be non-desert once it reached the deser, de-desrtifying the coast? Or would the wait not work for those waiting?

I never said it is a good thing. I'm just asking, what WOULD HAPPEN! Ur supposed to tell me, I don't know, thats why one asks questions.
 
This is the big IF of this century, when any meaningful increase may occur, and how do we define a such an increase!?

The Arctic and Antartic ice 'sheets' are said to be breaking up faster than expected. All this will add to the volume of water that makes up the seas of the world.

I used to live in a low-lying urban area of Cardiff, I'm glad in this respect that I've moved to 'higher ground' in the north of the City.

What does a sealevel increase mean?
It is not just the cities on the coast that will be effected, higher sealevels will mean wider river estuaries - backing up river water, German cities on the Rhine would also be effected.
Likewise, many America cities will be effected if the Mississippi starts to get wider
Bangledesh has enough problems, with flooding of its low-lying land, due the monsoons, but with higher sea levels! Perhaps they should invade Burma!?
Also, if you fancy a holiday in the Maldives - do it soon!

Water, may be a big factor in any future conflict - either not enough freshwater, or too much salt water.

Wars, may not be started by governments, but by people - as they 'invade' another country - that has higher ground.

Perhaps we'll get genetic engineering to give us gills!!?

It depends on the type of current that is going nere the coast. For example I live in Western Australia, and one of the reasions that we have so much deserts in our state is that there is a cold water current along the coast.
 
Well, we Dutch would probably lose our war against the water, and our nation would start to look like Greece.

I do think it would boost our economy, though. Even more ships would be able to go down the Rhine (because it would cover most of Southern Holland, presumably), and we can tax those.
 
No one is understanding the question. I'm asking waht would happen if went o nand the sea levels raised before 1980 at least. The answers make more sense in, like, regards to the future.
 
How quickly and when did the rising levels 1st become a concern? Can we in TTL's 2009, look back at the history of the sea level's rise in the 20th Century and draw rational/documentable conclusions about why it happened?

Sea level rise

The Arctic and Antartic ice 'sheets' are said to be breaking up faster than expected. All this will add to the volume of water that makes up the seas of the world.
Only ice on land increases sea level when it melts off into the sea. Ice floating in sea water displaces the same weight as it would if it melted (mass remains constant). Although ice on land displaces the land (a bit) so that when it melts the land rises (a bit).

I've been looking all over for a map program that redraws the world/regions/countries with higher sea levels.

The antarctic and Greenland glaciers melting will increase sea levels. The real 'snowball' effect comes with the Siberian permafrost melting. Not that it will run straight into the sea. It will release methane (swamp gas - a 'greenhouse' gas) and the swamp water will evaporate more than permafrost does. Some water will rain into rivers and the sea.
