Climate Change

[Alan V]

"Almost a quarter of all the glaciers in West Antarctica have been pronounced 'unstable'. This means, in the simplest terms, that they are losing ice to the ocean faster than they can gain it from falling snow. In the last 25 years most of the largest flows have accelerated the loss of ice fivefold. And in places some glaciers, including those known as Pine Island and Thwaites, have 'thinned' by 122 metres. That means that the thickness of the ice between the surface and the bedrock over which glaciers flow has fallen by almost the height of the Great Pyramid of Cheops in Egypt, and far more than the Statue of Liberty in New York or the tower of Big Ben in London. The conclusions are based on climate simulation matched against 800 million measurements of the Antarctic ice sheet recorded by the altimeters aboard four orbiting satellites put up by the European Space Agency between 1992 and 2017. The conclusion is published in the journal Geophysical Research Letters."
