The Alarming Speed of Ice Sheet Collapse in Antarctica.

Ice sheets can collapse into the ocean at speeds of up to 600 metres a day, according to a study based on sea floor sediment formations from the last ice age. The finding is a “warning from the past” for today’s world in which the climate crisis is eroding ice sheets. The research shows that some ice sheets in Antarctica, including the “Doomsday” Thwaites glacier, could suffer periods of rapid collapse in the near future, further accelerating the rise of sea level.
