The Earth’s axis is the imaginary line around which the planet rotates on itself. This is not solid, but moves slightly due to various natural factors, such as the movement of tectonic plates, the melting of glaciers or the gravitational pull of the moon and sun.
However, in recent decades, the Earth’s axis has undergone a more significant and accelerated change that has surprised and alarmed scientists.
According to a study published in Geophysical Research Letters, the Earth’s rotation axis has tilted about 80 centimeters eastward since 1993. The main cause of this phenomenon is excessive human extraction of groundwater for purposes such as consumption, agriculture or industry.
It is estimated that around 2,150 gigatons of groundwater were withdrawn during this period.
What are the consequences of this imbalance in the Earth’s axis?
The Earth’s axis determines the seasons, the length of day and night, and the distribution of heat and cold across the planet.
When the axis changes, these factors change, which can lead to extreme climate changes such as droughts, floods or storms. In addition, groundwater extraction lowers groundwater levels and reduces water supplies to rivers and oceans, affecting biodiversity and the water cycle.
Excessive groundwater extraction causes the Earth’s axis to tilt by almost a meter, endangering the balance and stability of our planet.
Urgent measures must be taken to reduce groundwater consumption and seek alternative and sustainable sources. This is the only way we can preserve our common home and secure our future.
