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 ...

The general outlines of the ice ages of the last several million years are pretty well understood. The timing of the glacial cycles has been controlled by cycles in Earth’s orbit, with the temperature ...

Glacial cyclicity of the Earth has often been considered on 100,000 year timescales, particularly for the Late Pleistocene (~11,700 to 129,000 years ago) swapping between periods of extensive polar ...

Full moon, new moon. High tide, low tide. These are dependable rhythms of our planet. It is not surprising then, that news of a “wobble” in the moon’s orbit — one with implications for the growing ...

Current observations indicate the Moon recedes from Earth at 3.8 cm per year, a rate that, if extrapolated, conflicts with the Moon's 4.5-billion-year formation timeline. Researchers analyzed ...

Experts will gather Saturday and Sunday at the Westin Mission Hills Resort in Rancho Mirage to examine ancient cultures and theories tied to the Great Year — otherwise known as the "precession of the ...

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 ...
