🌊🧵 1/ Vanderford Glacier, holding more than half-a-metre of global sea level rise, is retreating faster than any other in East #Antarctica (18.6 km of grounding line retreat 1996-2020!) It’s one of a number of glaciers in Vincennes Bay melted by deep warm water getting underneath.

The amount of ice flowing from Thwaites Glacier in West Antarctica has doubled in the span of three decades. These satellite images from 2001 and 2019 show the fracture and retreat of the glacier ice tongue floating on the Amundsen Sea, as it's melted from below.

1/ Crabeater seals are the most abundant top predator in the Southern Ocean and probably the most numerous large wild mammals on earth. Because they live almost their entire lives amongst floating sea ice around #Antarctica, it’s difficult to count them – total population is an estimated 15 million.
