New NASA data shows accelerated snowmelt in Greenland:

To understand why these trends are important to track, Tedesco explained one of the consequences of melting snow. “Although wet and dry snow look similar at first glance, wet and re-frozen snow absorb more of the sun’s radiation, reflecting only 50-60 percent back into the atmosphere. Dry snow, on the other hand, reflects about 85 percent of the sun’s radiation,” he said. “In other words, melting snow absorbs three to four times as much energy as dry snow, greatly affecting Earth’s energy budget.”
