The Sea Level Rise is so urgent that a 400 mile long WALL in the Sea is needed to enclose the North Sea.
Trump's border wall should be moved over there for this project.
LONDON — One dam would stretch some 300 miles from the coast of Scotland to Norway. The other, roughly 100 miles, would rise in the waters between northern France and Southeastern England.
Together, the mammoth structures proposed by scientists would completely enclose the North Sea and offer protection for tens of millions of Europeans threatened by rising sea levels caused by climate change.
The scientists behind the proposal, outlined in a paper published on Thursday in the American Journal of Meteorology, said that the scale of the project — which exists only in the broadest outlines at this point — reflected the urgency of the crisis.

The project would be one of the largest engineering feats ever attempted on the planet and would cost anywhere from $250 billion to $550 billion, according to the proposal — a cost the authors suggest could be covered by more than a dozen Northern European countries that would be protected by the barrier.
Some experts expressed doubt that damming the North Sea was the best solution for dealing with rising sea levels.

“In the end, we came to realize it’s such an extreme solution that it would be much better and much less dramatic to reduce our CO2 emissions and curb global warming so that we don’t need these kind of things,” he said in an interview.
If carbon pollution continues to grow, sea level rise by 2100 could exceed 40 inches (a meter), Mr. Groeskamp said.
If nothing changes, Mr. Kjellsson said, millions of people will be forced from their homes — effectively becoming climate refugees. Even today, coastal cities such as San Francisco and Manila are faced with the consequences of sea level rise.
By 2050, some 150 million people in low-lying coastal cities could find themselves below the high-tide line, threatening to submerge whole cities, according to a report by Climate Central, a science organization based in New Jersey.
The proposed dams would dwarf the largest such barriers built so far — the Afsluitdijk in the Netherlands, and the Saemangeum Seawall, in South Korea, which at 21 miles in length is the world’s longest sea wall.
For scale, the North Sea dams would require at least 51 billion tons of sand — roughly equal to the total annual use of that commodity in construction projects around the world.

I think the final cost will be 40x of whatever the initial estimate.
