Warm Ocean Currents Play Key Role in Melting Antarctic Ice Shelves

Yale Environment 360: Warm ocean currents are melting many of Antarctica's floating ice shelves from beneath, which in turn is speeding up the flow of land-based glaciers into the ocean and increasing global sea levels, according to a new study. An international team of scientists, led by researchers from the British Antarctic Survey (BAS), used 4.5 million measurements from a satellite-based laser altimeter that precisely measures the changing thickness of ice shelves. Using those readings and other data, the researchers...
