The Thwaites glacier is an important glacier in western Antarctica. It is already thought to account for about 4% of global sea level rise. This glacier has suffered a rapid retreat from the land shelf in just 6 months – a process that can naturally take several centuries.
The bigger problem that Thwaites glacier currently brings, is the fact that this glacier seems to largely be the dam wall, holding much of the ice back. As a result, while Thwaites glacier can increase water levels by an alarming amount, a collapse is predicted to increase global sea levels by between 90cm and 300cm.
In other words, this glacier alone, with a full collapse, as much as 5% of the worlds population will have to move as their home will be under water. Unfortunately far more people may well find that their way of live is no longer possible.
Regular readers of this blog will remember me mentioning this not long ago, unfortunately the last 6 months has shown the situation to be far worse.
