Antarctic Peninsula in 'dramatic' ice loss

Antarctic Peninsula in 'dramatic' ice loss:

 By Christina Garcés

 Satellites have cause a  dramatic change in the behaviour of glaciers on the Antarctica Peninsula, according to a Bristol University-led study.

_{The ice streams were  stable up until 2009, since when they have been losing   of 56 billion tonnes of ice a year to the ocean.}

_{Warm waters from the deep sea may be driving the changes, the UK-based team says.}

_{The details of the satellite research are published in Science Magazine.}

_{They include more than 10 years of space observations of a broad swathe of coastline roughly 750km in length, on the south-western sector of the peninsula.}

_{Here there is a multitude of glaciers slipping down mountainous terrain and terminating in the Bellingshausen Sea.}

_{"In  2009/2010, the surface in this part of the southern Antarctic Peninsula started to lower at a really quite dramatic rate, of 4m per year in some places. That's a pretty big signal," said Bristol's Prof Jonathan Bamber.}
