ScienceDaily: Pioneering new research sheds light on the impact of climate change on subglacial lakes found under the Greenland ice sheet. A team of experts, led by Dr Steven Palmer from the University of Exeter, has studied the water flow paths from one such subglacial lake, which drained beneath the ice sheet in 2011. The study shows, for the first time, how water drained from the lake -- via a subglacial tunnel. Significantly, the authors present satellite observations that show that a similar event happened...
