Chinese experts have come to the conclusion that over twenty years, a sharp acceleration in the melting of glaciers and global warming have changed the angle of inclination of the earth's axis. Scientists' research data is published in Geophysical Research Letters.
As you know, the rotation of any object or object depends on how its weight is distributed inside it. For our planet, the distribution of weight has changed constantly throughout its history, since the molten underground part of the Earth is constantly changing, involving changes in the surface of the ball in this process. The main factor in the displacement of the planet's weight is the huge masses of liquid water, both in underground cavities and on the surface.
The planet's constant fluctuations in weight since the early 2000s have been constantly tracked by satellite missions hosted by NASA. However, in their research, Chinese experts relied on data from the "pre-satellite" era of observations of changes in the tilt of the earth's axis.
To draw conclusions about changes on Earth since the early 1990s, experts analyzed data on the shrinking of glaciers at the poles, as well as statistics on data on the volume of groundwater that was pumped to the surface. It turned out that 26 years ago the direction of movement of the polar poles radically changed its direction.
Based on this, Chinese scientists have found that last year the pole drift speed was almost seventeen times higher than in 1995. These data will further help researchers to more accurately calculate the movement of the poles associated with climate change on our planet.
