Mars's Gravitational Pull Influences Earth's Deep Ocean Currents, Study Finds

Researchers uncover a 2.4-million-year cycle linking Mars's orbit to changes in Earth's deep-sea currents and climate patterns.

A new study reveals Mars's gravitational pull may be strong enough to influence Earth's deep ocean currents, contributing to a 2.4-million-year climate cycle.
Scientists from the Universities of Sydney and Sorbonne University used deep-sea sediment records to establish a connection between the orbits of Earth and Mars, and changes in deep ocean circulation.
The cycle is not linked to current rapid global warming caused by human activities but offers insights into natural climate variations and ocean dynamics.
Deep-sea eddies, or giant whirlpools, identified as a key factor in these cycles, could help mitigate the effects of a slowing Atlantic Meridional Overturning Circulation (AMOC).
The findings could improve climate models and our understanding of ocean circulation in a warmer world.
