Earth’s elliptical path around the Sun does more than keep the planet in a stable orbit. Because that path is not a perfect ...

A strip of cool water stretches west from South America along the equator, helping set the pace for some of the planet’s most important weather swings. That Pacific “cold tongue” helps steer the El ...

BEIJING, Jan. 22, 2026 /PRNewswire/ -- 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 ...

Add Yahoo as a preferred source to see more of our stories on Google. New research links Earth’s orbital wobble to 4,000–5,000-year climate swings during a hot, ice-free Cretaceous period. (CREDIT: ...

The ebb and flow of Pleistocene glacial cycles is not random; it follows a predictable pattern dictated by the distinct and deterministic influence of Earth’s orbital geometry, according to a new ...

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 ...

Climate can change fast, even when the planet looks stable. Earth has flipped into new patterns within decades in the past. During the last Ice Age, Greenland warmed by as much as 16°C over short ...

A new study from China University explores how millennial-scale climate variability, traditionally linked to ice-sheet dynamics, occurred during warm greenhouse house periods when ice sheets were ...
