A chunk of ice the size of Manhattan has broken away from Antarctica because of rising temperatures in the waters surrounding the continent, according to experts.
It comes as the UN World Meteorological Organisation announced on Friday that the ice surrounding the Arctic and Antarctic last month had hit a record low
"The missing ice in both poles has been quite extraordinary," David Carlson, director of the World Climate Research Programme, told a UN briefing in Geneva.
Satellite images released by NASA show a mile-long (1.6km) section of the Pine Island Glacier separating from the West Antarctic Ice Sheet between 24 and 31 January.
The glacier's last major iceberg break - an event known as calving - was in July 2015 when 225 square miles broke away from the glacier.
The most recent chunk is 10 times smaller, about the size of the island of Manhattan (22.7 square miles or 59 square km).
Scientists are still watching an iceberg - roughly a quarter of the size of Wales - which is said to be "hanging from a thread"
It is situated in the Larsen C ice shelf - the most northern major shelf in the Antarctic Peninsula.
Forecast to be one of the largest separations of its kind, the frozen mass has an area of 5,000 square km (1,930sq miles).
The iceberg will be 350m thick when it eventually breaks away.
Researchers believe the shedding of the shelf will lead to global sea levels rising by 10cm and could lead to the wider break-up of Larsen C.
