For millions of years, the Earth has oscillated between ice ages and warmer episodes. The movements of the ground beneath our feet could play a much more important role in this cycle than previously ...

Scientists at the University of Southampton have uncovered evidence from ancient rocks that Earth's climate continued to fluctuate during its most extreme ice age—known as Snowball Earth. During the ...

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 ...

Researches used rhenium as a proxy for fossil carbon in order to quantify the rate at which Earth naturally releases carbon dioxide into the atmosphere and found that high rates of carbon breakdown ...

Beginning around 2.5 million years ago, Earth entered an era marked by successive ice ages and interglacial periods, emerging from the last glaciation around 11,700 years ago. A new analysis suggests ...

Cycles in the growth and decay of Antarctica's ice sheets once shaped marine biological productivity thousands of miles away in the subtropical ocean, according to new research led by scientists at ...

Our existence is governed by natural cycles, from the daily rhythms of sleeping and eating, to longer patterns such as the turn of the seasons and the quadrennial round of leap years. After looking at ...

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 ...
