Earth’s elliptical path around the Sun does more than keep the planet in a stable orbit. Because that path is not a perfect circle, the distance between Earth and the Sun changes throughout the year, ...

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 ...

Earth is closer to the sun at some times of year than at others, with the time of closest approach shifting over a period of 22,000 years. This affects Earth's climate, including ice ages, but a team ...

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 ...

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 ...

A terrazzo star map at Hoover Dam turns a sunny overlook into a 26,000-year clock marking human ambition against moving stars now.

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 ...
