Antarctic Melting May Be Speeding Up, Scientists Say

Rising sea levels and melting polar ice-sheets are at upper limits of projections, leaving some human population centres already unable to cope, top world scientists say as they analyse latest satellite data.

...But even in east Antarctica, which is insulated from global warming by extreme cold temperatures and high-altitudes, new information shows the height of the Tottenham Glacier near Australia's Casey Base has fallen by 10 metres over 15-16 years.
