Given the Netherlands currently spends ~$1 billion dollars USD a year on sea-level control for 451 km of coastline and there are 1,634,701 km of coastline in the world, there is ~3625 times the coastline to control. That would be a minimum of ~$3625 billion USD in cost if the numbers are extrapolated.
Given the GDP of the world in 2011 was $6,966 billion this would be a minimum of ~52% of the world GDP each year to deal with sea level rise. This, of course could be higher in some areas and lower in others where the land is just given up to the sea. This also assumes all countries would bear the cost, which is not correct as those with coastlines will pay those costs. That is also only the cost of sea level rise and does not touch on the impacts on current agriculture or infrastructure. Most countries will not be able to afford this hit.
You are just making a joke. This sort of psudo-maths gibberish will never be believed even by the most insane Greenie.
The Neitherlands spends a lot maintaining a lot of land below sea level by 10m or more. Suggesting that we will need to spend the same on the Arctic ocean coasts is ...... beyond fantasy.
No, it is an average because we will spend much more per km building new defenses where we already have infastructures. I note that you have provided even less in the way of support for your claims. Which has more basis in reality, the use of cost per km data extrapolated out as an average and acknowledged as a very rough average, or the opinion of some random person on the internet pulling claims out of the air?
