A research team, composed of climatologists and an astronomer, have used an improved computer model to reproduce the cycle of ice ages (glacial periods) 1.6 to 1.2 million years ago. The results show ...

Dec. 10 (UPI) --During the last million years of Earth's history, the planet's glaciers have regularly expanded and receded, triggering periods of dramatic climate change. These glacial-interglacial ...

These ancient cores may contain clues about an unexplained change in Earth’s glacial-interglacial cycles, and could shed light on how human-generated emissions will shape our planet’s future. Reading ...

The climate modeling community has been particularly vexed by the glacial/interglacial cycles of the past three million years, when the Northern Hemisphere oscillated between times with and without ...

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 ...

At the end of Taylor Glacier in Antarctica, a hypersaline brine known as “Blood Falls” flows onto the surface. The red color is from iron oxide. Mineral deposits formed in the past from such fluids ...
