West Antarctica Glaciers Collapsing, Adding to Sea-Level Rise
Scientists warn that the Thwaites glacier is sliding into the ocean.
A massive glacier system in West Antarctica has started collapsing because of global warming and will contribute to significant worldwide sea-level rise, two teams of scientists warn in a pair of major studies released Monday.
Scientists had previously thought the two-mile-thick (3.2 kilometers) glacier system would remain stable for thousands of years, but new research suggests a faster time frame for melting.
A rapidly melting section of the West Antarctic Ice Sheet appears to be in irreversible decline and will sink into the sea, scientists at the University of California, Irvine and NASA reported Monday.
"This retreat will have major implications for sea-level rise worldwide," said Eric Rignot, a UC-Irvine Earth science professor and lead author of a study to be published
