Antarctica latest: NASA satellites reveal 'biggest' ice melt in 50 years – It's 'worrying'

NASA satellites over Antarctica have made a “worrying” discovery about the George VI ice shelf, recording the “biggest melt” in nearly 50 years.

NASA ’s Landsat 8 satellite photographed an 86-mile-long stretch of azure blue water on the George VI ice shelf. According to Christopher Shuman from the University of Maryland and NASA’s Goddard Space Centre, the melt is one of the worst seen in the last five decades. The glaciologist said: “It is the only complete view of such as widespread surface melt event on the George VI ice shelf captured in the nearly 50-year-long Landsat record.” Alison Banwell from the University of Colorado Boulder added: “This is the biggest melt ever we know to have occurred on the George VI ice shelf.” READ MORE: Antarctica: NASA satellites have discovered worrying amounts of ice melt (Image: NASA/GETTY) Antarctica: NASA data shows Antarctica and Greenland are losing ice mass (Image: NASA) Big Bang breakthrough: 'Pale echo’ of universe birth discovery exposed NASA’s Landsat satellites have been keeping a watchful eye on Antarctica since Landsat 1 launched in 1972. Since 1973, the US space agency has been recording periods of ice melt on the George VI shelf. But the recently discovered meltwater is the most worrying seen to date. NASA’s scientists are yet to figure out why the ice shelf is melting at such alarming rates. In the past, seasonal melting has been caused by wind patterns dragging warm air along the surface of the ice shelf. Related articles Read more: Daily Express
