Earth’s Rotation Is Slowing Down Faster Than Expected
Scientists have reported that Earth’s rotation may be slowing down faster than expected. The finding has drawn global attention. Researchers believe the change could be linked to climate change and the continued melting of polar ice.
According to the study, modern environmental changes may be affecting the physical movement of the planet itself. This is reported by BBC Science Focus.
The research was carried out by scientists from the University of Vienna and ETH Zurich in Switzerland. Their goal was to understand how the speed of Earth’s rotation changed over millions of years.
To do this, they examined fossil shells from ancient marine organisms found in ocean sediments. These remains preserved chemical traces from Earth’s distant past. Scientists used this evidence to estimate ancient sea levels and compare them with changes in the planet’s movement.
The results revealed an unusual trend. Researchers say the planet rotation slowing down may now be happening faster than at any point in at least the last 3.6 million years.
This makes the discovery especially important. Changes in Earth’s rotation usually happen very slowly. However, the new data suggests the current shift may be accelerating.
Scientists believe polar ice melt is one possible reason. Ice in Greenland, the Arctic, and Antarctica continues to melt into the oceans. That water spreads across the planet over time.
This changes how Earth’s mass is distributed. Even small shifts in mass can affect how quickly a planet rotates. Researchers often compare it to a spinning skater. When the skater extends their arms, the spin becomes slower.
Scientists discovered that climate change may be influencing more than temperatures and sea levels. It may also be affecting the motion of Earth itself.
Another concern raised by scientists was previously reported. According to them, Africa could gradually split into two continents in the future as a massive rift widens. Deep underground, powerful tectonic forces continue to slowly pull parts of the continent apart.
