Antarctic ice shelves melting 70% faster, study shows

The frozen fringes of western Antarctica have been melting 70% faster in the last decade, raising concern that an important buttress keeping land-based ice sheets from flowing to the sea could collapse or vanish in coming decades, a new study shows. An acceleration in the flow of massive ice sheets would add substantially to the ongoing rise of sea levels, according to Fernando Paolo, a geophysics PhD candidate at UC San Diego's Scripps Institution of Oceanography and lead author of the study published online Thursday in the journal Science. “They hold back the ice discharge from the ice sheet into the ocean," Paolo said. "In the long term, that is the main...
