According to scientists, the Amundsen Sea Embayment, which is the fastest-changing region in Antarctica, has experienced a loss of more than 3,000 billion tons of ice in 25 years. If all this ice were to be stacked, it would tower over 2 km tall, which is equivalent to 7.4 times the height of the Sh

ard in London. Alternatively, if it were to cover Manhattan, it would stand at a staggering 61 km, or the equivalent of 137 Empire State Buildings stacked on top of each other.

Dr. Davison, a Research Fellow at the Institute for Climate and Atmospheric Science at Leeds, said: “The 20 glaciers in West Antarctica have lost an awful lot of ice over the last quarter of a century and there is no sign that the process is going to reverse anytime soon although there were periods where the rate of mass loss did ease slightly.

These would have resulted in periods of heavy snowfall and periods of very little snowfall or a “snow drought”. Dr. Davison said: “Changes in ocean temperature and circulation appear to be driving the long-term, large-scale changes in West Antarctica ice sheet mass. We absolutely need to research those more because they are likely to control the overall sea level contribution from West Antarctica.

As it retreated, one of its tributary glaciers became detached from the main glacier and rapidly accelerated. As a result, the tributary glacier has now been named by the UK Antarctic Place-names Committee, Piglet Glacier, so that it can be unambiguously located and identified by future studies.
