COVER Melting water streams from an iceberg in Disko Bay on the western coast of Greenland. The iceberg calved from the Ilulissat Glacier (also known as Sermeq Kujalleq or Jakobshavn Glacier), one of the world's fastest-moving and most studied glaciers. Melting polar ice sheets are one consequence of human-induced global warming and could contribute to a substantial increase in global sea levels in the future. See page 750.
