Experts have found that the Greenland ice sheet lost a record 1-million tonnes of ice per minute in 2019
The ice sheet shrank by 532bn tonnes last year as its surface melted and glaciers fell into the ocean.
This is enough ice to fill seven Olympic-sized swimming pools per second.
Satellite data has been collected since 2003. The 2019 loss was double the annual average since then of 255bn tonnes. Almost that amount was lost in July 2019 alone.
If the entire Greenland ice sheet melts, sea level would rise by six metres.
