Global floating ice in "constant retreat" - study

The world's floating ice is in "constant retreat", showing an instability which will increase global sea levels, according to a report published in Geophysical Research Letters on Wednesday.

Floating ice had disappeared at a steady rate over the past 10 years, according to the first measurement of its kind.

"It's a large number," said Professor Andrew Shepherd of the University of Leeds, lead author of the paper, estimating the net loss of floating sea ice and ice shelves in the last decade at 7,420 cubic kilometres.
