Mars' Influence Reveals Secrets of Earth's Climate Cycle

3/12/2026

Summary

Story summary

Mars influences Earth's orbital patterns and ice-age timing, according to the University of California, Riverside (UCR) researchers, with implications for planetary systems.
Removing Mars from the simulations eliminates the 100,000-year climate cycle.
Mars' mass affects Earth's axial tilt and seasonal sunlight, thereby influencing ice growth.
The findings may improve understanding of sediment records and geological dating.
The study is published in the Publications of the Astronomical Society of the Pacific.
