Scientists: Greenland losing 200 million tonnes ice every year
Using satellite data, Scientists confirmed via Glacier-covered Greenland has had an average net loss of 200 billion tons of ice every year since 2003.
The Gravity Recovery and Climate Experiment (GRACE) which can detect mass changes on the surface of the Earth over time. GRACE does this by detecting subtle increases and decreases in gravity, which is directly related to the mass below the two orbiting GRACE satellites.
Roughly, 200 million tonnes of ice is the amount needed to fill enough railroad coal cars to encircle the Earth.
The study was published in Proceedings of the National Academy of Sciences.
