As the ice melts, the earth’s crust will melt. In a local way, the researchers thought until then. But satellite data now calls into question the idea. Over the past two decades, melting Arctic ice has caused significant erosion of much of the Earth’s crust in the northern hemisphere.
When the ice melts, the And this We have already shown this to researchers. But today a (United States) assumes that the affected area will extend far and wide. Hundreds, thousands of kilometers from melted ice.The bottom is distorted. Years of study
The researchers worked on satellite data collected between 2003 and 2018. . And how the Earth’s crust is deformed. They measured the horizontal displacement of the latter. They also observe that in some regions, the earth’s crust moves farther horizontally than vertically. On average, deformation is measured in tens of millimeters per year. This is a large part of the Northern Hemisphere.
To help us understand, Sophie Coulson, geophysicist, makes a proposal , Meaningful film. “Imagine a wooden board floating on the surface of the water . If you push the board down, the water at the bottom will also go down. If you remove the board, you will see water moving vertically to fill the empty space. “
Research shows that the Earth’s crust is shrinking beneath these plateaus as ice melts from Greenland, Antarctica and the Arctic Islands. https://t.co/F7sTA8YVBB

The implications are not yet clear
When ice melts, it changes the face of the earth. Because it’s especially boringThe crust of the created earth, will have an impact on it By changing the slope of the bed under the snow cap.
Researchers at Harvard University today recall that what they noticed already happened in the past. About 2.6 million years ago, a It covered northern Europe and Scandinavia with snow. Until about 11,000 years ago. “Even after the ice has melted, the earth is still dripping, Sophie Coulson insists. The earth acts like a very slow fluid. The processes of the ice age take a very, very long time to expand, so we can still see results today.. ⁇
According to the researchers, the effects of these movements Substantial. This study first shows the recent mass loss And glaciers cause motion in space on the Earth’s surface Spatial size is higher than previously identified. Searching this signal now in databases of regional and large-scale navigation satellite systems will, in principle, create advanced barriers to the distribution of ice mass or structural fluctuations. Of the earth.
