'Dream team' to study ice loss on Greenland glacier to better forecast rising oceans

Last month a new projection of sea-level rise by the year 2050 spurred headlines showing more coastal cities around the world will be submerged than earlier models have predicted. Just how fast and how high sea levels rise globally will be determined by the melting of ice sheets in Greenland and Antarctica. However, the acceleration, retreat and thinning of glaciers where they meet ocean water are still understood poorly.
