Rising sea levels prompt massive dam proposals and glacier warnings

New scientific projections and modeling indicate a significant acceleration in sea-level rise, driven by melting ice sheets and warming ocean currents. A new computer model developed by researchers from the University of California, Irvine, and NASA Jet Propulsion Laboratory suggests that the Thwaites Glacier in Antarctica—often called the ‘Doomsday Glacier’—could contribute up to 3 centimeters to global sea-level rise by 2100. This is double previous estimates, as warm seawater is infiltrating deep beneath the ice, destabilizing its connection to the seabed.

In response to rising sea levels, which some forecasts predict could reach 60 centimeters to over a meter by 2100, oceanographers Sjoerd Groeskamp and Joakim Kjellsson have proposed a massive infrastructure project. The plan involves constructing two giant sea barriers to separate the North Sea and the Baltic Sea from the Atlantic Ocean.

The first proposed barrier would stretch 161 kilometers between Cornwall, England, and Brittany, France, designed to withstand an Atlantic rise of up to 2 meters. The second structure would span 476 kilometers, connecting parts of Scotland, the Orkney and Shetland Islands, and the western coast of Norway. Such measures aim to protect millions of people and coastal cities, including Gdańsk and Szczecin, from catastrophic flooding.
