Scientists to drill through world's highest glacier
Climate-change scientists are set to travel to the Himalayas, aiming to become the first to successfully drill through the Khumbu glacier, world's highest glacier which elevates from 4,900 to 7,600 metres. Drilling in the 17-km-long glacier, located near Mount Everest in northeastern Nepal, will help study the glacier's internal structures, how water flows through it and measure its temperature.
