Int'l - World's biggest iceberg FOUR TIMES the size of Greater London is steaming towards the open ocean and could pose a risk to shipping vessels

The 2,239-square-mile A68 iceberg is speeding up in its trajectory north towards the open Southern Ocean. The massive berg that's roughly the size of Delaware broke off from the Antarctic Peninsula back in 2017. A68 broke away due to iceberg calving – the breaking away of masses of ice from the edge of a glacier. Scientists are hopeful that the berg breaks apart once it reaches the ocean so it doesn't cause havoc for ships.

The world's biggest iceberg is about to enter the Southern Ocean after breaking free from the Antarctica more than two years ago.

The iceberg, called A68, measures nearly 2,300 square miles (6,000 square kilometres), making it about four times the size of Greater London and almost the same size as the US state of Delaware.

The enormous berg, which weighs one trillion tonnes, broke off from the Antarctic in 2017 and has been steadily travelling north ever since.

A68 is currently at about 63 degrees South latitude, but once it reaches the open ocean it's likely to break down due to rougher waters.

It's being carried north by currents and in the last year has started to accelerate in its journey northwards towards South Georgia, an island in the southern Atlantic Ocean.
