balance causes competing edges favor flow forces greenland ice interior loss melting race recently sheet snow
The melting of ice at the edges of the ice sheet is also increasing, which causes the ice to flow faster. A race is going on in Greenland between these competing forces of snow build-up in the interior and ice loss on the edges. But we don't know how long they will be approximately in balance with each other or if that balance has already tipped in favor of the recently accelerating outflow from glaciers.
