Global warming changes the axis of Earth's rotation

Global warming changes the axis of Earth's rotation

The axis of the Earth's rotation is not fixed. This is reflected in a shift in the position of the poles. A movement that scientists have been following for some time, and today they stress that man-made global warming and, more broadly, human activity have greatly accelerated this natural movement.

The slope of the axis of rotation of the Earth relative to the plane of the ecliptics is not stable. Scientists are still trying to understand what is behind this change. But the way the water is distributed across the surface of our planet seems to be an important factor. And today, researchers are telling us that the melting of glaciers due to the ongoing anthropogenic global warming has shifted water to sufficient to accelerate the shift of the North Pole from the south to the east in the mid-1990s.

In order to arrive at this conclusion, researchers calculated the total loss of water stored on land in the 1990s, based on the melting of glaciers and the estimation of groundwater runoff, and the loss of water from polar regions is the main driving force of the polar drift.

However, the increasing melting of global warming ice cannot explain the entire drift. Although researchers have not gone this far in their analysis, they believe that the remaining gap may be the result of disturbances in non-polar regions, particularly due to the unsustainable pumping of groundwater for agriculture.

These results show, according to researchers, the extent to which human activity can affect our Earth, even the movement of its axis of rotation, but without any real influence on our daily life, because the operation could at best change the duration of our days by just a few milliseconds.
