Vast Antarctic iceberg 'threat to marine life'

A vast iceberg that broke off eastern Antarctic earlier this month could disrupt marine life in the region, scientists have warned.

They say the iceberg, which is 78km long and up to 39km wide, could make it harder for the area's colonies of Emperor Penguins to find food.

But British and Australian scientists disagree on whether it could also cause major problems to our own weather patterns.

Tom Symonds reports.
