As Greenland glaciers melt, scientists warn again that the sea is rising

HELHEIM GLACIER, Greenland – This is where the refrigerator door of the Earth is left open, where the glaciers are dwindling and the sea begins to rise.

David Holland, a specialist in air and ocean science at New York University, who follows what is happening in Greenland from top to bottom, calls it "the end of the planet." He speaks more of geography than of the future. Yet, in many ways, this place is the writing of the warmer and wetter future of the planet.

On August 15, Mugu Utuaq, a Kulusuk resident in Greenland, said that winter, which lasts up to 10 months when he was a child, can now last up to five months. Scientists are working hard in Greenland to try to understand the extremely rapid melting of ice.

It's so hot here, just inside the Arctic Circle, that one day in August, coats stay on the ground and that Holland and his colleagues are working on melting ice without gloves. In one of the nearest cities, Kulusuk, the morning temperature reached a shirt sleeve 52 degrees Fahrenheit.

Ice Holland is on for thousands of years. It will be gone here a year or two, adding even more water to the rising seas in the world.

Summer this year hits Greenland hard with record heat and extreme melt. Scientists estimate that about 440 billion tonnes of ice, perhaps more, will have melted or wedged off the Greenland Ice Cap. It is enough water to flood Pennsylvania or the country of Greece with a depth of about one foot.

In just five days, from July 31 to August 3, more than 58 billion tons have melted from the surface. That's more than 40 billion tons more than average for this time of year. And these 58 billion tonnes do not even count the huge calving nor the hot water that gnaws the glaciers from below, which can be a huge factor.

And one of the places hardest hit by this hot summer in Greenland is here, south-east of the frozen giant island: Helheim, one of Greenland's fastest-retreating glaciers, has shrunk more than 10 km since the arrival of scientists in 2005.

Several scientists, such as NASA oceanographer Josh Willis, also in Greenland, are studying ice melt from above, explaining that what is happening is a combination of man-made climate change and natural weather but strange. The glaciers here are shrinking in the summer and growing in the winter, but nothing like this year.

Summit Station, a nearly 3-km-high research camp located to the north, warmed above zero a second time this year for a record time of 16.5 hours. Before this year, this station was above zero for only 6.5 hours in 2012, once in 1889 and in the Middle Ages.

Scientists report that this year is approaching, but not exceeding the extreme summer of 2012 – the worst year in modern Greenland history, scientists said.
