Human-Constructed Dams Have Shifted the Earth’s Poles, Scientists Say

People have built so many dams in the world so that the poles of the planet offers new researches away from the rotation of the planet.

People in the past 200 years, increase about three feet (one meter), and in global sea levels (a meter), and in global sea levels (21 millimeters) and global sea levels (21-millimeters) and global sea levels (21-millimeters) and global sea levels) Geophysical Research Letters.

This slip is possible, because the strong shell of the earth forms a stiff bark around the melted layer of Gooey Magma. This means that a significant amount of mass is redistributed along the surface of the planet, the most external rock layer wobbles relative to the melted interior of the ground. When this happens, different areas on the surface of the earth end directly over the planet’s rotation reading. As a result, the planet’s poles pass through different surface places than before, a phenomenon known as a true polar.

“When it trap water behind the warehouses, it produces water from the oceans, and the mass around the world also redistributes the mass,” Natasha Valencik, Harvard University is the author of a graduate student and the author of new work statement.

The study in the study affects the volume of the volume of water, their places, storage, and his team analyzed the previously published global database. Earlier, the database caused a decrease in the sea level of 6,862 large dams built between 1835 and 2011. Collectively, these paragraphs keeps water enough to fill the large canyon twice.

The results showed that the global paragraph cause the earth poles in two stages. The first stage, since 1835-1954, in the construction of a warehouse in North America and Europe coincided with a boom. These areas passed to the equator, and as a result, the North Pole, Russia, Mongolia and China moved about 8 inches (25 centimeters) to the east of the 103rd meridia.

During the second wave of the warehouse construction, most dams were built between 1954 and 2011, Asia and East Africa. As a result, the North Pole changed 22 inches (57 centimeters) to the 117th Meridian West passing from Western South America and the South Pacific. Is not a polar walking line; Instead, this is a road that does not add a total turn to full 3.7 feet.

Although the results are relatively subtle, the researchers stressed the need for water stored in the warehouses while predicting the increase in future sea levels. In the 20th century, global sea levels rose 4.7 to 7.7 centimeters (12 to 17 centimeters), but according to the valency, about a quarter of the dam was arrested.

“Depending on where you place paragraphs and reservoirs, the geometry of the sea level will change,” he said. “These changes are another factor we should think because it can be very great and important.”
