Abrupt climate shifts are well documented in Earth's history and are commonly associated with ice-sheet dynamics during past ice ages. However, how similar millennial-scale climate variability could ...

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

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

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 ...

Scientists have long debated what causes glacial/interglacial cycles, which have occurred most recently at intervals of about 100,000 years. A new study reported in the March 24 issue of Nature finds ...

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 ...

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 ...
