Greenland shed an extraordinary 600 billion tonnes of ice by the end of summer last year.
This melt-driven loss would have raised global sea levels by 2.2mm, say scientists who've just published an analysis of satellite gravity measurements taken over the Arctic.
Of course, when winter set in, some of that mass would have been recovered as it snowed across the ice sheet.
The data comes from the joint US-German space mission known as Grace-FO.
It's actually a pair of satellites that circle the globe, sensing the "lumps and bumps" in Earth's gravity field that correspond to variations in mass.
Key signals being detected are changes in the amount of water stored on land surfaces and the withering state of the planet’s great ice fields.
