"Scientists have mapped a critical area of seafloor in front of Thwaites Glacier in West Antarctica in high-resolution for the first time, giving them a window into how fast it has retreated and moved in the past.
The glacier has been an important consideration for scientists trying to make predictions about global sea level rise.
This massive ice stream is already in a phase of fast retreat leading to widespread concern about exactly how much, or how fast, it may give up its ice to the ocean.
Experts suggest a total loss of Thwaites and surrounding icy basins could raise sea levels from three to 10 feet.
Thwaites is really holding on today by its fingernails, and we should expect to see big changes over small timescales in the future..." Evening Standard
Three to ten feet higher sea level would be catastrophic.
