HELHEIM GLACIER, Greenland (AP) – This is where the refrigerator door of the Earth is left open, where the glaciers are shrinking and the sea is starting 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.
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 10.7 degrees Celsius.
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 (400 billion tonnes) of ice, perhaps more, will have melted or become detached from the giant Greenland icecap. It's enough water to flood Pennsylvania or the country of Greece about 35 centimeters deep.
In just five days, from July 31 to August 3, more than 58 billion tons (53 billion tons) 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, southeast of the frozen giant island: Helheim, one of Greenland's fastest-retreating glaciers, has shrunk about 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 research camp nearly 3 km high and far north, has warmed above freezing point twice 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.
"If you look at climate model projections, we can expect to see larger areas of the ice layer melting for longer periods of the year and greater mass loss to the lake. 39; future, "said Tom Mote, scientist in ice sciences from the University of Georgia. "There is every reason to believe that years that look like this will become more commonplace."
A NASA satellite revealed that the Greenland ice cap had lost about 255 billion tonnes of ice a year between 2003 and 2016, with the loss rate generally deteriorating during this period. Almost all of the 28 Greenland glaciers identified by Danish climatologist Ruth Mottram have declined, including those from Helheim.
In Helheim, ice, snow and water seem to go on forever, encircled by bare mountains that show no sign of ice but overlap in winter. The only thing that gives an idea of the scale is the helicopter carrying Holland and his team. He is dwarf in the landscape, an almost imperceptible red dot against the ice cliffs where Helheim stops and his remains begin.
These ice cliffs measure somewhere between 70 meters and 100 meters high. Right next to them, the remains of Helheim – sea ice, snow and icebergs – form an almost white expanse, with a mixture of shapes and textures. It's common for water to get stuck in the middle of this bright white, nearly fluorescent blue that looks like windshield wiper fluid or Kool-Aid.
While pilot Martin Norregaard attempts to land his helicopter on the broken part of what used to be a glacier – a mixture called "muddy" – he searches for ice stained with earth, a sign that it is firm enough for the helicopter to settle. White ice could hide a deep crevice leading to a cold, deadly dive.
Holland and his team set up to install a radar and a GPS to follow the movement of the ice and to better understand why salt water, hot and once tropical, attacking the "belly" of the glacier bubble on the surface.
"It takes a long time to grow a layer of ice, thousands and thousands of years, but they can be broken or destroyed pretty quickly," Holland said.
Holland, like Willis of NASA, suspects that warm, salty water coming in part from the Gulf Stream in North America is playing a bigger role than predicted in the melting ice of Greenland. And if that's the case, it's probably bad news for the planet, because it means a faster increase in melting and a rise in sea level. Willis said that by 2100, Greenland alone could cause a rise in sea level of 3 or 4 feet (more than one meter).
It is therefore crucial to know what role air plays above and the water below.
"What we want for this is a forecast of the pack ice," Holland said.
In this distant landscape, the sound travels easily for miles. Every few minutes, there is a slight growl that sounds like a thunder, but it is not. It's the ice that crackles.
In the small town of Kulusuk, about 40 minutes away by helicopter, Mugu Utuaq says the winter, which lasted up to 10 months when he was small, can now be as short as five months. That counts for him because as a fourth-largest dog sled in Greenland, he has 23 dogs and must race there.
They can not run in the summer, but they must always eat. So Utuaq and his friends will hunt the whale with rifles in small boats. If they succeed, what they did not do that day, dogs can eat whale.
"People get rid of their dogs because there is no season," said Yewlin, who wears only one name. He ran a team of sled dogs for tourists at a hotel in the nearby town of Tasiilaq, but they can not do it anymore.
Yes, melting glaciers, less ice and warm weather are perceptible and very different from his childhood, said Kulusuk Mayor, Justus Paulsen, 58 years old. Of course, that means boats need more fuel to get around, but that's okay, he said.
"We like that because we like to have a summer," said Paulsen.
But Holland looks at the Helheim Glacier from his base camp and sees the situation as a whole. And that's not good, he said. Not for here. Not for the Earth as a whole.
"It's nice to have a planet surrounded by glaciers," Holland said.
