More than 10 billion tonnes of ice melted in 24 hours in Greenland last week, scientists have said.
With historically high temperatures of 22C, Denmark's Meteorological Institute said the Greenland ice sheet ended July with a net mass loss of 197 Gigatonnes from the beginning of the month.
The highest daily total of the melt season was registered on 31 July with 11 Gigatonnes of mass loss, which equals over 10 billion tonnes of ice melted in 24 hours.
Documentary filmmaker Caspar Haarloev took videos of Greenland's ice melting at historic records on 1 August while producing a climate change documentary called "Into the Ice".

He said: "It has been incredibly fascinating to explore the big and mysterious cryosphere. All this ice is just lying there like a big sleeping monster.
"No one cared about it before it started to melt. Now everybody cares. And for a very good reason," Mr Haarloev told Reuters as he continues producing his documentary.
