I am thinking of a scenario in which a climatic change and rising sea levels (whether true or not IRL) is threatening the Earth and I have learned that changes in sea levels might be caused by melting glaciers, I propose an idea in which countries around Beringia (the region) begin to create a large enough landmass connecting between Asia and America (creating the Bering land bridge) assuming it would cool up the climate in the Arctic. I am asking if this scenario set around 2040-2060 might be possible if someone had to propose the idea. Adding that in this scenario, Russia collapses and new countries located next to Alaska decide to help the US in the process.
The size of the project is rather large, ending up to look like this:
