A new study of the world’s glaciers reveals that they are melting at a faster pace than previously estimated, posing an increasing threat of inundation to coastal communities and low-lying islands around the world.
The research found that other than the ice sheets of Greenland and Antarctica, glaciers lost 676 gigatons of ice per year on average between 2000 and 2019. The losses were said to have accelerated sharply during the period as global heating became more acute. Some glaciers have already vanished, with others expected to do so by the end of the century.
This is a particular threat in South Asia, where mountain glaciers are an important source of fresh water to rivers such as the Ganges, Brahmaputra and Indus.
