NASA has identified three processes responsible for wobbles in Earth's axis of rotation: ice mass loss primarily in Greenland, glacial rebound, and mantle convection.
Researchers used more than 120 years of data to decipher how melting ice, dwindling groundwater, and rising seas are nudging the planet’s spin axis and lengthening days. Days on Earth are growing slightly longer, and that change is accelerating.
However, the new research shows that persistent groundwater extraction over more than a decade shifted the axis on which our planet rotates, tipping it over to the east at a rate of about 1.7...
Earth’s axis has shifted due to climate change. Melting glaciers and overuse of groundwater account for much of the change. Regions like Alaska and the Himalayas have experienced the most...
Climate change is likely the cause of a recent shift in the Earth's axis of rotation, a new study suggests. Melting glaciers around the world – a result of rising atmospheric temperatures from...
As the Earth’s glaciers recede at unprecedented rates, the planet’s mass is being constantly redistributed. The team’s findings suggest that we can expect to see the hydrosphere continuing to cause the Earth’s axis to shift in coming years.
Earth’s axis hasn’t been wandering enough to affect the seasons, which are determined by the planet’s tilt. But fine patterns and variations in the planet’s spin matter hugely to the...
The Earth’s axis of rotation is shifting due to climate change and movements in the Earth’s interior. The corresponding polar motion is triggered by shifts in mass such as the melting of polar ice caps.
Climate change appears to be affecting Earth’s core, as well, as a result of melting ice and shifts in the planet’s rotational axis. The researchers behind the new study built a 120-year model...
NASA has identified three processes responsible for wobbles in Earth's axis of rotation: water mass loss primarily in Greenland, glacial rebound, and mantle convection. A typical desk globe is designed to be a geometric sphere and to rotate smoothly when you spin it.
