NASA announces that the dangerous Antarctic glacier is collapsing

A giant 40-square-mile and 300-meter-high steeple grows at the bottom of the Glacier Thwaites in the west of Antarctica, confirming that the ice disappears.

That is, a new investigation led by a research team has confirmed

Similarly, the observation of the observation at the bottom of the glacier in Antarctica is considered necessary to calculate how rapidly rising sea levels in the world respond to climate change.

Researchers discovered thunderstorms between Thwaites, where the flow of sea water and the bottom glacier melted.

The size and explosive growth of the new hole, however, surprised them. It's enough to have 14 million tons of ice, and in the last three years the majority of these ice melts.

"We suspect that Thwaites did not go well below the years," said Eric Rignot of the University of California, Irvin and NASA Jet Propulsion Laboratory (JPL). Rignot is the author of the new research
Published in Science Advancements. "Thanks to the new generations of satellites, we can finally see the details," he said.

The radar on the ice was revealed by NASA's Operation IceBridge, which analyzes the relationship between the campaign began in 2010 and the global polar regions and the global climate.

The researchers used the synthetic speed opening of the Italian and German spacecraft constellation data. This distinctive resolution is very important for treating it through an interferometric radar, since the bottom surface has been moved between images.

"[El tamaño de] The glacial cavity is essential in the melting process, "said Director General of the JPL's Pietro Milillo, researcher." As heat and water penetrate into glaciers, it melts faster, "he said.

The numerical shapes of ice sheets use a fixed shape to represent cavity beneath the ice, to change and grow the cavity. This new finding means that this limitation is likely to underestimate these patterns as Thwaites is losing ice.

Thwaites Glacier, Florida, the size of the United States, now accounts for approximately 4% of the global sea level rise. It is enough ice cream to increase the ocean in the world to more than 2 centimeters and make glacial areas around it, the sea level rising 2.4 centimeters when the ice is lost.

Thwaites is one of the hardest places to reach the Earth, but is better known than ever. The United States National Science Foundation and the United Kingdom's National Environmental Research Council are developing a five-year project to respond to critical questions about processes and features. The Thwaites Glacier International Collaboration will begin experiments in the southern hemisphere in the summer of 2019-20.

The giant summit is located below the main ridge of the Western West Glacier, the westernmost part of the Western Antarctic Peninsula. In this region, when the tide goes up and down, the ground connection is recovered and advanced approximately 3 to 5 kilometers.

From the freshwater edge, the year-to-year glacier has been a constant rate of 0.6 and 0.8 km. However, despite the fact that the landline's permanent retirement rate is stable, the fusion rate is very high for Glacier.
