At 260 square kilometres (30km long, 10km wide), the ice island (which is another way of saying "incredibly massive iceberg") that recently broke off the Petermann Glacier in Greenland is the largest since the 1960s. It was spotted by a Canadian scientist last week on the northwestern corner of Greenland. We're unlikely to have a re-enactment of Titanic, or another gushing oil well, as the ice island is pretty far from shipping lanes and oil rigs, and it still has to navigate the Nares Strait before escaping into Baffin Bay. Scientists are unsure as to exactly what caused this phenomenon, but "global warming" cropped up in the discussion. Read more: The AFP and BBC News.
