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 ...

Earth's climate has swung between ice ages and warmer periods for millions of years, driven by subtle changes in our planet's orbit and axial tilt. These variations, known as Milankovitch cycles, ...

"Without Mars, Earth's orbit would be missing major climate cycles. What would humans and other animals even look like if Mars weren't there?" ...

Stephen Kane, a professor of planetary astrophysics at UC Riverside, was skeptical when he read recent studies that showed the gravitational pull from Mars being connected to Earth’s long-term climate ...

Milankovitch cycles describe slow, predictable changes in Earth’s orbit and tilt that influence long-term climate patterns. Over tens of thousands of years, these cycles have driven ice ages, warming ...

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 ...
