A quarter of the world depends on Glacier Melt for their Water; it will be Gone Sooner than Expected

The Conversation

By Mathieu Morlighem | – Mountain glaciers are essential water sources for nearly a quarter of the global population. But figuring out just how much ice they hold – and how much water will be available as glaciers shrink in a warming world – has been notoriously difficult. In a new study, scientists mapped the […]

Antarctica’s ‘doomsday’ Glacier: how its Collapse could trigger global Floods and swallow Islands

The Conversation

By Ella Gilbert | – The massive Thwaites glacier in West Antarctica contains enough ice to raise global sea levels by 65cm if it were to completely collapse. And, worryingly, recent research suggests that its long-term stability is doubtful as the glacier haemorrhages more and more ice. Adding 65cm to global sea levels would be […]
