About 23 million years ago, a huge ice sheet spread over Antarctica, temporarily reversing a general trend of global warming and decreasing ice volume. Now a team of researchers has discovered that ...

New research shows how sea ice growth in the Southern Hemisphere during certain orbital periods could control the pace of ice ages on Earth. Earth is currently in what climatologists call an ...

Changes in Earth's orbit have helped pace climatic change for millennia. Scientists are now trying to understand whether - and how - these changes remodeled the landscapes our ancient ancestors ...

A pattern of encroaching and retreating ice sheets during and between ice ages has been shown to match certain orbital parameters of Earth around the sun, leading to researchers being able to predict ...

Over the last two-and-a-half million years the Earth has undergone more than 50 major ice ages, each having a profound effect on our planet's climate. But what causes them and how do we predict when ...

It has long been known that characteristics of the Earth’s orbit (its eccentricity, the degree to which it is tilted, and its “wobble”) are slightly altered on timescales of tens to hundreds of ...

In a recent publication in Science Bulletin, a multidisciplinary team of authors from Tongji University, the Second Institute of Oceanography (Ministry of Natural Resources), the Institute of Earth ...

PROVIDENCE, R.I. [Brown University] -- Earth is currently in what climatologists call an interglacial period, a warm pulse between long, cold ice ages when glaciers dominate our planet's higher ...

SANTA CRUZ, CA–About 23 million years ago, a huge ice sheet spread over Antarctica, temporarily reversing a general trend of global warming and decreasing ice volume. Now a team of researchers has ...
