2.4-million-year cycle of deep-ocean currents linked to Mars' gravitational interactions, solar energy, and warmer climate discovered by researchers.

Researchers from the Universities of Sydney and Sorbonne have discovered a surprising 2.4-million-year cycle of deep-ocean currents, possibly influenced by Mars' gravitational interactions with Earth. The cycle corresponds with periods of increased solar energy and a warmer climate. The study, published in Nature Communications, suggests that understanding these ocean-bottom currents could help model future climate outcomes.
