Grasses, shrubs and mosses are growing and expanding around Mount Everest and across the Himalayan region as the area continues to experience the consequences of global warming, researchers have found. Scientists from the University of Exeter in the United Kingdom used satellite data to establish increases in subnival vegetation -- plants that grow between the tree line and the snow line -- in the Himalayas.
