On Monday , scientists warned in a major new study issued that Two-thirds of Himalayan glaciers, the world's "Third Pole", could melt by 2100 if global emissions are not reduced,. And even if the "most ambitious" Paris Agreement goal of limiting global warming to 1.5 degrees Celsius is achieved, one-third of the glaciers would go, according to the Hindu Kush Himalaya Assessment.
Reports show that the glaciers feed 10 of the world's most important river systems, including the Ganges, Indus, Yellow, Mekong and Irrawaddy, and directly or indirectly supply billions of people with food, energy, clean air and income. Glaciers in the Hindu Kush-Himalaya (HKH) region are a critical water source for some 250 million people in the mountains as well as to 1.65 billion others in the river valleys below.

However Impacts on people from their melting will range from worsened air pollution to more extreme weather, while lower pre-monsoon river flows will throw urban water systems and food and energy production off-kilter, the study warned. It was published by the Kathmandu-based International Centre for Integrated Mountain Development (ICIMOD) in Nepal, one of eight countries on the front line.
