long been known that the Earth is not perfectly spherical.As a result of the last ice age, which ended about 11 000 years ago, the equator was at a greater distance from the nucleus than the pole.Today, the volume of the planet are changing again.

how to change the volume of the Earth before



lingering ice age ended eleven thousand years ago and lasted, according to the ideas of scientists, about 2.5 million. Years significantly deformed the planet: a huge mass of ice that accumulate for centuries, in some pointIt exceeded the critical level, causing the earth's crust and mantle, in fact, flattened, displacing the "extra" on the line of the equator.So it turned out that the Earth's surface at the North Pole about 20 km closer to the nucleus than the surface on the "belt" of the planet.

After the ice age again a gr
adual return to a spherical shape, annually reduces the thickness of the equatorial bulge of about one millimeter.But at the moment this process stopped and even reversed.

As increasing amounts of the planet today



Scientists from the American University, located in Colorado, based on the data of satellites GRACE, claimed that the volume of the Earth's equatorial belt increases again.This is due to the fact that global warming is melting ice contributes to the active North and South poles: about 382 billion. Tons of ice annually into water.All the "surplus" by natural processes shrink to the equator, causing "growth" of the planet in this area.

What are the implications of these changes



distance from the core to the surface, increasing the influx of water from the poles, changing about 7 millimeters per decade.Globally, it would not seem like much, but geophysicists and meteorologists say that the living conditions are becoming less favorable: the changes in the climate provoke natural disasters and changes in the ecosystem.

Scientists predict sea offensive to some countries in the coming century: the water may be the northern islands, Scotland, part of Iceland.Floods will suffer the Netherlands and Denmark.On the south side of the melting of the ice threatens the island states of the Indian and Pacific Oceans.Significant climate change will occur in areas that flooding and flooding will not get any.
