Dam the Bering Strait, Use Nuclear-Powered Propellers to Melt Poles.

Arkady Markin, Soviet engineer; Proposed that the United States and Soviet Union build a gigantic dam across the Bering Strait and use nuclear power–driven propeller pumps to push the warm Pacific current into the Atlantic by way of the Arctic Sea. Arctic ice would melt, and the Siberian and North American frozen areas would become temperate and productive.
