"Mars's Influence on Earth's Deep Ocean Circulation Uncovered"
A new study suggests that Mars may be influencing Earth's deep ocean currents, driving "giant whirlpools" through a gravitational interaction that affects the shape of their orbits and the distance from the sun. These 2.4 million-year cycles correlate with warmer climates and more vigorous ocean currents, but are not linked to current human-caused warming. The study's authors also propose that these eddies could potentially mitigate the impacts of a potential collapse of the Atlantic Meridional Overturning Circulation (AMOC), a crucial ocean circulation system. However, some experts caution that the link between Mars and ocean circulation is speculative, and the evidence for deep ocean circulation being stronger in warm climates is thin.
