"Without Mars, Earth's orbit would be missing major climate cycles. What would humans and other animals even look like if ...

Previous research on deep-sea sediments had suggested that Mars might influence Earth's climate, but the magnitude of this ...

Earth’s slow axial wobbles—known as precession cycles—do not just shape long-term climate trends. A new study led by ...

Researchers find that shifts in Earth’s orbit can trigger abrupt climate changes, even in warm periods without ice sheets.

How does Mars influence Earth’s climate cycles? This is what a recent study published in the Publications of the Astronomical Society of the Pacific | Space ...

Researchers discovered Mars subtly affects Earth’s orbit and axial tilt. These small changes help trigger ice ages and ...

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 ...

On its own, Earth would shift toward another ice age in about 10,000 years, scientists say. But humanity's greenhouse gas emissions may have radically shifted the climate's trajectory. Credit: Matt ...

Earth wobbles on its axis like a spinning top, a motion called precession. This wobble takes about 26,000 years to complete one full circle. Different stars have served as the North Star throughout ...
