Earth's slow axial wobbles—known as precession cycles—do not just shape long-term climate trends. A new study led by researchers from China, Belgium, and Austria shows that these orbital motions can ...

Researchers find that shifts in Earth’s orbit can trigger abrupt climate changes, even in warm periods without ice sheets.

Climate can change fast, even when the planet looks stable. Earth has flipped into new patterns within decades in the past.

This illustration shows how Earth’s spin axis (blue) is tilted from perpendicular, causing it to precess and trace out a circle over about 26,000 years. The brightest star nearest the North Celestial ...

Regular readers of my column certainly know how to use the Big Dipper to find the North Star (aka Polaris). Some folks believe Polaris is important because it’s the brightest star in the heavens, and ...

Precession-driven fluid dynamics concerns the intricate motions arising when a rotating body experiences a slow, conical motion of its spin axis, a phenomenon that is pivotal in both geophysical and ...

Scientists have determined exactly how Earth's orbit and tilt affect glaciation and deglaciation, based on the length of ...
