A documentary filmmaker took videos of Greenland's ice melting at historic rates on Friday. With historically high temperatures of 22 degrees Celsius, scientists from Denmark 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 July 31 with 11 gigatonnes of mass loss, which equals over 10 billion tonnes of ice melting in 24 hours.
