Is the Earth approaching a never-ending day?
Our planet faces unprecedented challenges due to climate change, and these changes are not limited to rising temperatures or natural disasters only, but rather include astronomical phenomena that may affect our lives indirectly. Therefore, in this article, Earth Guards reviews the impact of climate change on the movement of the Earth, and how the melting of ice may lead to lengthening the day and changing the axis of rotation of the planet Earth, so continue reading to discover more about this important topic.
Climate change is not just a phenomenon embodied in hot weather or heavy rain, its impact includes the movement of our planet itself, as a recent study – a study supported by NASA – revealed that the melting of ice caps in the Arctic and Antarctic regions causes a gradual slowdown in the Earth’s rotation; Which leads to an increase in the length of the day, and at the same time indicates the extent of the impact of human activities on our planet.
The reason behind the long days
In a study published by the American Academy of Sciences (PNAS), it was found that the slowdown in Earth’s rotation is due to a change in the distribution of masses on the surface of our planet. As the ice melts in the polar regions, water flows into the tropical oceans, which changes the Earth’s center of gravity and slows down its speed. This effect is known in physics as “Moment of Inertia”, which is a term that refers to the force that affects the speed of rotation of objects based on the distribution of masses around the axis of rotation.
The observed slowdown in the Earth’s rotation
From the year 1900 to the year 2000, the Earth witnessed an increase in the length of the day. This increase ranged between 0.3 and 1 millisecond. Then this increase accelerated to reach 1.33 milliseconds. If climate change continues at the same pace, it is expected that this value will increase to reach 2.62 milliseconds by the year 2100.
The impact of the slowdown in modern technologies
The previous numbers may seem – at first glance – to be just a slight change, but these simple changes may have a severe impact on many sensitive technical systems, as the Earth’s slowdown affects – for example – systems that depend on precise timing, such as GPS systems, online financial services, and even some space technologies. These systems require constant modification. To ensure its continued proper operation.
Climate change takes over the moon
If the tidal movement of the moon affects the speed of the Earth’s rotation, then climate change has a more severe impact, which leads to an increase in the length of the day, which indicates the seriousness of this climate change! Regarding this, Benedikt Soja, a researcher at the University of Zurich, says: “Human influence on the planet has become greater than we imagined, and this indicates that climate change has profound effects that we may not be able to predict completely”.
In conclusion,Earth Guards stresses the need to take urgent measures to reduce gas emissions; To protect our planet from accelerating climate change. The article here raises a question about the extent to which we can slow down these changes, and whether the Earth will remain on this path towards an unknown future, or not?
