We’ve long known that the Moon affects the tides, but it now transpires that another great celestial force is playing games with the world’s oceans. Scientists have discovered a secret connection between the orbits of Earth and Mars, and found that this cosmic duet plays an important part in global warming.
Researchers have found that every 2.4 million years, the interaction between Earth and Mars results in key changes to deep ocean currents, which are linked to periods of increased solar energy and a warmer climate. The study, published in the journal Nature Communications, analyzed deep-sea sedimentary data to uncover these cycles.
