New research suggests that Mars’ gravitational pull is influencing Earth’s climate and ocean currents in a 2.4-million-year cycle. This cycle, described as a cosmic butterfly effect, alters Earth’s orbit around the sun and leads to warmer climates and increased deep ocean circulation. By studying deep-sea sediment records, researchers discovered the impact of these cycles on the behavior of ocean currents. The findings indicate that this natural climate cycle is not connected to the current global warming crisis caused by human activities. However, understanding the role of deep ocean eddies in response to warmer climates could provide valuable insights into how climate change affects ocean circulation. Some scientists remain skeptical about the link between Mars and these cycles, highlighting the speculative nature of the proposed connection. The research suggests that deep ocean eddies could help maintain effective ocean circulation in the event of a collapse of the Atlantic Meridional Overturning Circulation.
