Melting of Himalayan glaciers has doubled in past 20 years

The rate glaciers are melting in the Himalayas has doubled in just 20 years, according to a study which examined 40 years of satellite data.

Glaciers have been losing more than a vertical foot and a half of ice each year since 2000. This equates to 8 billion tons of water being released – or the equivalent of 3.2 million Olympic-size swimming pools.

The rate of melting is more than double that which took place between 1975 and 2000, according to the study published in Science Advances. It is the latest indication climate change is threatening the water supplies for 800 million people living downstream.

These glaciers currently harbour 600 billion tons of ice and they may have lost as much as one quarter of their mass over the past four decades.
