The cliff stops the rapid rise of the sea level



A new study revealed that ice cliffs may appear in a process called slipping off and could cause a rapid rise in sea levels. The high cliffs of ice fall sharply, scientists say. ( Byron Pariz and colleagues )

Ice cliffs emit in the sea and emit in a process called "birth", but Greenland scientists believe that another process may cause a rapid rise in sea levels.

Helheim and Jakobshavn, a team of researchers who fled over glaciers on the eastern coast of Greenland, explained that a slumping process called ice slits could be much larger at a faster pace. Implications of this process can be huge.

Richard Alley, a co-author of the new study published in the journal GeologyHe said that if what happened in Helheim happened over the next hundred years, Antarctica suggests that the rapid increase in sea levels could be higher than expected.

What is Slumping?

The glaciers that drain the ice sheet often end up in vertical cliffs. While the glacier enters into the sea, its fragments break.

These incredible events often occur when the sea melts in the ice when the ice breaks down. However, Alley and his teammates have decided that the mass is not needed to flow into the sea, because it requires a solid one. This is all slumping.

Helheim glaciers end at the shore, at least 100 meters above sea level. In the last flight, the scientists saw the cracks, they went to the end of the glacier on Helheim ice.

Alley explains that when sinking or losing a mass of rock, it moves away from the ground and goes down a hill. The slumps are usually marked with a material broken by a stepped foot, which is moving downward to move the material.

Helheim's glacial features can usually be found in the slump field. That's why Alley and his scientists wonder if the fate of ice is the same. He has a headache and then emphasizes the ice in the water level that is maximized.

How rugged it is in the Arctic

Alley has said that geologists are worried about decades of slumps. He and his team had decided to try the slumps ice cliffs, Helheim glacier tracking event at an event. They measure the position, velocity and movement of the ice.

As they saw, there was a significant acceleration in the ice flow before the initial decline occurred and then the thickness of the glacier then rises. The rest of the ice clam rotates above and below the sea.

Alley and his colleagues realized that 100-meter-high ice-thumping ice rises to 100 percent. Community common events are very slow because the ice melts. On the other hand, the redundancy occurs without waiting to melt ice, researchers have found.

"Soon we will fall … baseball fan … boom," said Alley.

In some parts of Antarctica, the glacier bed is at least 2,000 meters above sea level, creating a much larger ice shelf. Alley was worried, the cliffs could face higher on the slopes. If slipping in Antarctica, the rise in sea level may be faster.

Meanwhile, Alley and his team will have more research in the future. He said he still wants to understand the breaking of the ice and how it is applied slipping. They plan to gather more observational data to improve their models.
