Antarctic glaciers are possibly more sensitive to changes in sea temperature than was thought, new research shows.
For the first time in history, scientists have drilled 600m (1,968ft) to the bottom of the Thwaites glacier in West Antarctica, and taken measurements of where the ice is melting.
Footage taken in 2019 at the start of the study shows researchers from the British Antarctic Survey and the US Antarctic programme discovering the bottom of the ice looking like “staircases”, suggesting the ice is melting at a faster rate in weak spots.
The study will enable scientists to make more accurate forecasts on how quickly sea levels will rise as global temperatures increase in the decades to come.
