Earth's internal heat drives rapid ice flow, subglacial melt
Science Daily GeologyThe North Atlantic Ocean is an area of active plate tectonics. Between 80 and 35 million years ago tectonic processes moved Greenland over an area of abnormally hot mantle material that still today is responsible for the volcanic activity of Iceland. The mantle material heated and thinned Greenland at depth producing a strong geothermal anomaly that spans a quarter of the land area of Greenland. That distant history of the North Atlantic region contributes to the present-day ice loss, suggests a new report.
