Land increases in size, with just the belt of the equator, scientists say. Our planet is put on weight "because of melting ice, which was caused by global warming. This increases the girth of the waist of our Earth . Our planet is not a ball in the full sense of the word, we all know this since the days of school. The earth's surface at the North Pole about 21 km closer to the nucleus than at the equator. Land acquired a form of 11 thousand years ago, as a result of the glacial period. Recall that while the planet for two and a half million years has experienced a temperature drop of the surface and atmosphere. One day, the moment when the mass of ice was so great that it changed the ice crust and mantle, the planet priplyusnuv top and squeezing the "superfluous" to the equator.
After the end of the Ice Age Earth gradually began to return to the ideal spherical shape. According to scientists, "bulge" at the equator every year decline of about a millimeter. But today the process of reducing the width of the girth suddenly turned around. This statement was made by researchers of the American University of Colorado. They studied this satellite program GRACE, which measure changes in climate and gravity on Earth.
To such conclusions American researchers at the University of Colorado, examined data from satellites of the program GRACE, which measure the gravitational and climatic changes on the planet. According to scientists, to reduce the width of the loops of the planet prevents the rate of melting ice in the North and South Poles. In the year of 382 billion tons of ice fill the volume of the oceans, and because of this huge influx of water stopped the Earth "lose weight", but instead began to increase at the equator.
As a result of ice melting this volume equator of the Earth every 10 years, increasing to seven millimeters. Scientists have determined that the Earth began to "plump up" since the early 90's. last century, when the change in mass of ice and water in the ocean for the first time in millennia acquired a massive character.
