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 ...

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 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 ...

Scientists have finally put to bed a long-standing question over the role of Earth's orbit in driving global ice age cycles. Scientists have finally put to bed a long-standing question over the role ...

MOLINE, Ill. — It was in the 1920s that a Serbian geophysicist, Mulitin Milanković, theorized that variations in Earth's tilt and wobbling about its axis impact the amount of energy being received ...
