Glaciers on the edge: Stunning photos from Greenland

This is where Earth's refrigerator door is left open, where glaciers dwindle and seas begin to rise. New York University air and ocean scientist David Holland, who is tracking what's happening in Greenland from both above and below, calls it "the end of the planet." He is referring to geography more than the future. Yet in many ways this place is where the planet's warmer and watery future is being written. It is so warm here, just inside the Arctic Circle, that on an August day, coats are left on the ground and Holland and colleagues work on the watery melting ice without gloves. In one of the closest towns, Kulusuk, the morning temperature reached a shirtsleeve 52 degrees Fahrenheit (10.7 degrees Celsius). Summer this year is hitting Greenland hard with record-shattering heat and extreme melt. By the end of the summer, about 440 billion tons (400 billion metric tons) of ice — maybe more — will have melted or calved off Greenland's giant ice sheet, scientists estimate. That's enough water to flood Pennsylvania or the country of Greece about a foot (35 centimeters) deep. In just the five days from July 31 to Aug. 3, more than 58 billion tons (53 billion metric tons) melted from the surface. That's over 40 billion tons more than the average for this time of year. And one of the places hit hardest this hot Greenland summer is here on the southeastern edge of the giant frozen island: Helheim, one of Greenland's fastest-retreating glaciers, has shrunk about 6 miles (10 kilometers) since scientists came here in 2005.
