Again, when you dig deeper, and I am following all the links here, there are lots of 'mays' and 'coulds' etc. and no exact science. Antarctica is melting faster than scientists thought it would. Thwaites Glacier is melting from the bottom, and when it breaks up and sinks into the sea, who knows what will happen.
