Today, an ultra-hot column of partial molten rock lies beneath Iceland and feeds the country's dramatic volcanic landscape, but it wasn't always this way. Due to the slow-shifting of Earth's crust in the region, this same hotspot sat beneath Greenland millions of years ago. And when it did, a new study has found, it softened the mantle rock in a way that has recently come to fool scientists trying to gauge ice loss in the area. So much so, that it has been losing around 20 gigatons per year more than we previously thought.
