Scientists Warn of Unprecedented Changes to Earth’s Rotation

Every day, Earth takes a little longer to spin. This change is very small, just fractions of a millisecond. However, the forces behind this change are enormous.

A new study says this change is the biggest in 3.6 million years. It happens because polar ice sheets and glaciers are melting due to climate change. When this ice melts, water moves from the poles into the oceans. This change makes the Earth rotate slower.

Scientists already knew climate change affects Earth’s spin. Now, researchers from the University of Vienna and ETH Zurich looked at the past. They found that today’s change has never happened before.

The exact length of a day is always changing. Forces like the Moon’s gravity can pull on Earth. Researchers found that climate change is now as strong as these forces. They studied tiny sea creatures called benthic foraminifera to find out how Earth’s spin has changed over millions of years.

By the end of this century, climate change will be the main cause of longer days, even more than the Moon’s gravity. This small change can affect GPS systems and weather patterns. Scientists are now looking at how other factors, like groundwater loss, will change Earth’s spin.

True False

The change in Earth's rotation is primarily caused by the Moon's gravity.

True False

Researchers studied the impacts of climate change on Earth's spin over millions of years.

True False

The study found that today's change in Earth's rotation has happened several times before.

True False

Benthic foraminifera were used to understand the spin of Earth.

True False

Climate change will not have an impact on GPS systems and weather patterns.

True False

Earth takes a little longer to spin every day, changing by just milliseconds.

The study indicates this change in Earth's rotation is the biggest in million years.

When ice sheets melt, water moves from the into the oceans.

Scientists believe that by the end of this century, climate change will be the main cause of days.

Research shows that forces like the gravity also affect Earth's rotation.

The exact length of a day is always changing due to various such as climate change.
