The crack-up

The world's largest ice sheet has started to melt along its coastal fringes, raising fears that global sea levels will rise faster than scientists expected. Scientists had thought the ice sheet was reasonably stable, but measurements taken from Nasa's gravity recovery and climate experiment (Grace) show that it started to lose ice steadily from 2006.

"If the current trend continues or gets worse, Antarctica could become the largest contributor to sea level rises in the world. It could start to lose more ice than Greenland within a few years," said Jianli Chen, of the University of Texas at Austin.


"We're seeing these kinds of climate change effects all around the world now," Chen said.

However, the Town Hall in the London Borough of Waltham Forest is well above sea-level, so there is really nothing at all to worry about.
