– Greenland's ice sheet is melting fast due to global warming and being replaced by vegetation
– An estimated 11,000 square miles of ice sheet and glaciers have melted over the past three decades, representing about 1.6% of Greenland's total ice and glacier cover
– The last time Greenland was this green was possibly during the Medieval Warm Period, according to Viking record
– Loss of ice mass in Greenland contributes to global sea level rise and freshwater intrusion into the ocean can affect climate and weather
– Greenland is projected to continue becoming greener as ice diminishes further and vegetation expansion
– High-resolution satellite images have been used to analyze the land cover changes that are taking place on Greenland
– Greening via vegetation expansion is already well underway in Greenland.
