Warm ocean water reaching Antarctica threatens ice shelves, scientists warn

Potential long-term displacement and economic disruption for coastal populations worldwide if sea levels rise significantly.

At the edge of the world's most remote continent, warm ocean water is quietly doing what ice ages once prevented — reaching beneath Antarctica's ice shelves and eroding the frozen barriers that hold back glaciers of almost incomprehensible scale. Scientists, aided by underwater robots, are tracing the pathways of this intrusion, trying to understand not just how it is happening, but how quickly the consequences will travel northward to every coastline on Earth.
