Ice output: Open process that accelerates care dragging 22:40

American scientists from the University of Colorado in Boulder showed an unexpected connection between the melting of glaciers and tectonic activity. 10 thousand years ago, the disappearance of Lawrence Ice Shield not only raised the sea level, but also accelerated the movement of the North American plate 25%. The study was published scientifically magazine Nature.

Using computer modeling, he rebuilt the geophysical events and then the last glacial age. The calculations showed that the discharge of a giant ice load was not only the vertical rise of the world shell (the so -called isostatic pipe reaction), but also a significant horizontal displacement of plates.

Especially in the inconsistency zone between the Atlantic Middle Rest-Tektonic plates, there have been noticeable changes. In the period of 12 thousand and 6000 years ago, the enlargement rate may increase by 40% per year compared to normal 2 cm. This discovery shows their sensitivity to climatic changes by changing the idea of ​​tectonic processes to extremely slowly.

The study also sheds light on the history of Iceland’s volcanic activity. Scientists argue that the accelerated expansion of Oceanic Ridge can contribute to intensive explosions during this period and provide additional ways to reach the surface of the magma.

These findings are particularly important in modern warming. Although the existing rates of Greenland glaciers are insufficient for a significant effect on tectonics, more students (ice loss) can re -activate such processes.

“The melting of the ice of Grönland and Western Antarctica can potentially strengthen volcanism on the ridges of Central Ocean,” he said.

For the first time, the study has made new expectations in understanding the interaction of climate and geodynamic processes by evaluating the impact of students on horizontal movements.

Previously, scientists discovered “Degradation” of one of the important climate regulation mechanisms.
