Large Antarctic iceberg seen very far north; global warming blamed

Giant iceberg heading for Australia - Telegraph

A giant iceberg double the size of Sydney Harbour is on a slow but steady collision course with Australia, scientists have said.
...
Dr Neal Young, a glaciologist working for the ADD, said that if the iceberg eventually reached Australia waters, it would crash into the continental shelf causing a magnitude three to to four tremor.
...
Dr Young said an iceberg the size of B17B had not been seen so far north since the days when 19th century clipper ships plied the trade route between Britain and Australia.
...
Originally three times its current size, the iceberg broke off Antarctica's Ross Ice Shelf in 2000 along with several others.

Dr Young said sightings of large icebergs could become more frequent if sea temperatures rise through global warming.
