Mount Everest from research helicopter
View of the peak of Mount Everest from inside a research helicopter flying in the Himalayas. Scientists have been collecting snow and meltwater samples. The seasonal melting of the Himalayan snow and ice supplies water for the major rivers of south Asia, including the Ganges and the Indus, which provide irrigation for crops that feed millions of people. Loss of the ice will lead to low water levels and droughts. Bare rock absorbs more heat from the Sun than ice does, making the ice-free regions warm even faster. Filmed in the Himalayas, Nepal.
