Mars's Surprising Impact on Earth's Climate Cycles
Researchers have discovered a previously undetected 2.4-million-year climate cycle driven by the gravitational interaction between Earth and Mars, affecting deep-sea currents and global warming. By analyzing deep-sea sediment records spanning 65 million years, the study found evidence of a connection between the changing orbits of Earth and Mars, past global warming cycles, and the speeding up of deep-ocean currents. The findings suggest that warmer oceans have more vigorous eddy-driven circulation, which may play a crucial role in counteracting potential ocean stagnation in a warming future.
