POPSIce Shelf Collapses in Antarctica A trend of "extraordinary warming" over the past 50 years in Antarctica has caused the loss of several ice shelves, Matthias Braun of Bonn University, and Angelika Humbert of Münster University, said in a statement. The researchers also warned that the last strip of ice on Wilkins would disappear soon. "The remaining plate has an arched fracture at its narrowest position," they said, "making it very likely that the connection will break completely in the coming days." —Lauren Morse
