Key quote from the article: "The entire glacial area Kris refers to is the Amundsen Sea Embayment in the western Antarctic, which would raise sea levels by 10 feet if the Thwaites ice platform and plug were to collapse. It would take the rest of West Antarctica (Thwaites alone holds two feet of SLR) with it)."

That's an imminent 3 metre sea level rise, within single-digit years.

80% of Bangladesh (pop. 200M) live less than 2M above sea level.
