Satellite data collected by the US space agency NASA shows Thwaites has been losing alarming amounts of ice into the Amundsen Sea.
This is worrying because the glacier is losing more ice than it can recover further inland by snowfall.
Ted Scambos, a senior scientist at the University of Colorado, warned in 2020: “What the satellites are showing us is a glacier coming apart at the seams.
“Every few years a new area seems to be letting go and accelerating.
“Like taffy being stretched out, this glacier is being drawn into the ocean.”
