This photograph shows ripples in the surface of Denman Glacier in East Antarctica that throw shadows against the ice. The glacier is melting at a faster rate now than it was from 2003 to 2008. The glacier retreated 3.4 miles (5.4 kilometers) from 1996 to 2018, according to a new study by scientists at NASA’s Jet Propulsion Laboratory and the University of California, Irvine.
