The New York Times (NYT) reports in “A New Idea to Save the Climate? Dam the Bering Strait.” that scientists have proposed building a 50-mile-long dam between Alaska and Russia to stabilize the Atlantic Meridional Overturning Circulation (AMOC) in order to prevent climate catastrophe. This is a seriously risky idea. The proposal is not an engineering plan grounded in observational need, but rather is computer-model thought experiment based on speculative tipping-point scenarios not justified by data concerning the AMOC or an understanding of what the possible future consequences might be for humans, the oceans, and sea life.
The author describes an article published in Science Advances where the idea of a cross continental dam across the Bering Strait is proposed as a “proof of concept,” noting that the dam could, under certain modeled conditions, prevent an AMOC collapse. It further explains that the findings come from a computer model of Earth’s climate, not from direct evidence that the AMOC is about to fail. That distinction is critical.
