The vast ice sheet of Greenland underwent a remarkable transformation for a few days this month when scientists observed an unprecedented melting of its frozen surface.
Scientists say there has been a freak event in Greenland this month: Nearly every part of the massive ice sheet that blankets the island suddenly started melting.
The total volume of water that has melted from all of the world's polar ice sheets, ice caps and mountain glaciers over the past decade would repeatedly fill Britain's largest lake, Windemere, more than 13,000 times, according to one of the most comprehensive studies of the Earth's frozen "cryosphere".
