Sea levels might rise much faster than thought, data from Greenland suggest

A new study suggests that the largest ice sheet in the world will add more water to the rising sea levels than previously thought. Scientists are concerned that the trend may not be limited to the island.

The study used a combination of gps and computer modeling to estimate how much ice is being lost due to climate change.

By the end of this century, NEGIS melting will add more than one inch of water to the ocean level. It's equal to the entire contribution to sea level rise made by the island of Greenland over the past 50 years.

Climate change can be seen from space.

After the coastal part of the ice stream broke off in 2012 the NEGIS ice-melt accelerated. The new data shows that the wave of rapid ice-thinning was much deeper than previously thought. Scientists were able to measure the thickness of the ocean from the northeastern coast of Greenland.

The contribution of ice dynamics to overall mass loss will be larger if this is true.

Morlinghem said that the whole system may be more sensitive to changes happening in coastal areas than previously thought.

It was found in the study that the melting continued even during the winter of 2021.

Shfaqat Abbas Khan, a researcher at the University ofDenmark and the first author of the new study, said that the basin is thin and the surface speed is increasing. We believe that the glaciers will retreat further inland over the coming decades and centuries. It is hard to imagine how this retreat could be stopped.

Sea level rise predictions will be affected if the findings are confirmed, as they show ocean levels rising by 8 to 38 inches by the end of the century. The authors concluded that the sea level rise will have catastrophic consequences for people in low-lying areas and coastal areas around the world.

Eric Rignot, a professor of Earth system science at the University of California, Irvine, is one of the co-authors of the paper. Data collected in the interior of ice sheets helps us better represent the physical processes included in numerical models and in turn provides more realistic projections of global sea-level rise.

The 27th Conference of Parties to the United Nations Framework Convention on Climate Change is taking place in the Egyptian coastal city of Sharm el-Sheikh. The summit aims to identify solutions for a wide range of climate related emergencies, including the energy crisis and the increasing severity of extreme weather events.

In the journal Nature, the study was published.
