The fingerprints of human-caused climate change have made it Antarctica, a new study shows
THE TOWERING GLACIERS of West Antarctica hold the fate of the world’s coasts in their flanks. Their collapse could send sea levels up by at least a foot by 2100—and potentially much more.
For years, scientists have watched and learned that those glaciers are crumbling and melting, the rate speeding up over the decades and imperiling the stability of the entire ice sheet. But while the science was clear that human influences on climate would affect the ice down the line, it has…
