Climate Cycle Linked to Earth-Mars Gravitation

• 13 Mar 2024

New research reveals a previously undetected climate cycle tied to Earth-Mars gravitational interaction.

• Newly Discovered Climate Cycle: Study in Nature Communications unveils 2.4-million-year climate cycle linked to Earth-Mars gravitational tug-of-war.
• Cycle impacts deep sea currents and global warming patterns, adding to understanding of natural climate rhythms.
• Milankovitch Cycles and Ice Ages: Serbian astrophysicist Milutin Milankovitch's cycles influence Earth's long-term climate through orbit changes.
• Gravitational jostling of planets alters orbits, affecting ice ages with predictable patterns.
• Earth and Mars Relationship: Astronomical “grand cycles” include slower rhythms, such as 2.4-million-year cycle related to Earth-Mars orbits.
• Deep-sea sediment study reveals connection between orbit changes, global warming, and ocean currents.
• Impact on Ocean Circulation: Warmer periods coincide with more vigorous deep-ocean currents, shaping sedimentary records over millions of years.
• Intensifying deep-ocean eddies in warmer climates may counteract potential ocean stagnation.
• Future Trajectory: Interplay between Earth-Mars influence, Milankovitch cycles, and human-driven global warming depends on greenhouse gas emissions.
• Understanding long-term climate cycles crucial for predicting future climate scenarios.
