Scientists from Harvard University have determined that human activity affects the movement of the magnetic poles of the earth. When a Natasha Valentich geophysical group discovered, the construction of nearly 7,000 large dams around the world distributed a block of water on the planet so that the rotating axis of the Earth's crust turned one meter compared to the inside generator.

The accumulation of water in reservoirs not only changes the balance of mass on the earth's surface, but also causes a decline at the level of the ocean to 21 million. The water was detained behind the dams, as the present, pulled out the rotating shell of the planet, resulting in a change of the position of the Arctic on the surface of the Earth – first to the east, towards Russia, and then to the west, to North America.
The authors noted that the North from the reality in the space did not change, but the planet's bark has changed, creating the effect of real polarization. The damaged dams were organized by about a quarter of sea level growth in the 21st century – about 1.2 mm per year, partly compensating for the consequences of climate change.
Experts emphasize: When evaluating future changes in sea level and the dynamics of magnetic poles, it is necessary to consider the influence of those technical projects. The location and size of the new reservoirs can significantly change these processes.
In April, scientists explained the acceleration of soil rotation by losing moisture from the soil and its repeatment, becoming one of the factors in the change of the balance of the planet's mass.
