Millimeter deviations from the expected wobble of the Earth's axis are giving geophysicists clues to what happens 1,800 miles underground, at the boundary between the Earth's mantle and its iron core.

On its own, Earth would shift toward another ice age in about 10,000 years, scientists say. But humanity's greenhouse gas emissions may have radically shifted the climate's trajectory. Credit: Matt ...

In 2019, scientists detected a strange wobble deep below the Earth’s surface that oscillates roughly every 8.5 years. Now, by mapping minute changes in the Earth’s rotation, the team has come up with ...

Last month I wrote about why the Tropic of Cancer and the Tropic of Capricorn are related to the 23.5 degree tilt of the Earth’s axis: The Sun’s furthest point north or south, called the solstice, is ...

Earth’s climate has never been static. It shifts between warm interglacial periods and deep freezes, driven by complex ...

Earth's core isn't exactly aligned with its mantle, which results in a cyclical wobble, new research finds. When you purchase through links on our site, we may earn an affiliate commission. Here’s how ...
