Global warming has shifted the earth's axis

on Sat Sep 29, 2018 1:44 pm
The Earth's axis has shifted by 10 meters over the past 100 years. One of the reasons is melting glaciers against the background of global temperature rise

This is reported on NASA's website.

Unlike the globe model, Earth is not an ideal sphere at all. When it rotates around the axis (imaginary line through the North and South poles) it drifts and swings. This is called polar motion. Measurements during the XX century show that every year the axis deviates by 10 centimeters. Thus, for a century, it deviated by 10 meters.

Scientists have come to the conclusion that this process occurs through three factors, which have roughly equal impact. The first is thermal convection in the mantle of the earth, it occurs from the reasons independent of humans. The second one is glaciation (movement of the earth's surface in areas of glaciation). During the last glacial period, the Earth's surface sank under heavy glaciers - as a mattress sinks under the weight of a person. Since now that ice melts, Earth slowly returns to its original position.

And the third factor is the loss of glacial mass in Greenland. It is caused directly by human activity and caused by global warming. As the temperature increased during the XX century, the glacial mass of Greenland decreased. In fact, during this period, about 7,500 gigatons of Greenland ice melted. This raised the level of the oceans, and, accordingly, increased the drift of the earth's axis.

-The unusual inclination of Uranus, which distinguishes its orbit from others in the solar system, may be due to a collision with a huge icy protoplanet twice as hard as the Earth.

-New photos of the newborn planet were first obtained : European astronomers photographed the planet for the first time in history at the stage of formation in the protoplanetary disk surrounding the young star.

-Scientists say they have found evidence of the existence of water geysers on the smallest of the four largest Jupiter satellites, called Galilean, Europe.

-Find out how it's going to fly through the Orion Nebula . Astronomers and NASA visualization specialists combined data from the Hubble and Spitzer space telescopes (visible and infrared ranges) and created a video of such a flight.
