Greenland ice sheet darkening at the edges as it melts

Greenland ice sheet darkening at the edges as it melts

The changes in the reflectivity of the surface of the Greenland ice sheet where studied from the start of the 1980s up until 2015 using images from weather satellites.

This study revealed that the border areas of the ice sheet have clearly become darker during July and August of each year, particularly from the start of the 2000s through to 2012. The study confirmed that the flow of meltwater from the surface of the ice sheet into the sea has then the largest factor contributing to the recent shrinking of the ice sheet.
