By studying the history of Totten's advances and retreats,A full 300 km retreat may take "several hundred years", but still...
researchers have discovered that if climate change continues unabated,
the glacier could cross a critical threshold within the next century,
entering an irreversible period of very rapid retreat.
This would cause it to withdraw up to 300 kilometres inland in the
following centuries and release vast quantities of water, contributing
up to 2.9 metres to global sea-level rise.
