A BBC story on the new study, “The spatial and temporal evolution of Pine Island Glacier thinning, 1995 – 2006,” (subs. req’d) explains:
Calculations based on the rate of melting 15 years ago had suggested the glacier would last for 600 years. But the new data points to a lifespan for the vast ice stream of only another 100 years.
The rate of loss is fastest in the centre of the glacier and the concern is that if the process continues, the glacier may break up and start to affect the ice sheet further inland.
