These cycles, referred to as “astronomical grand cycles,” appear linked to gravitational interactions between Earth and Mars.
Climate and Earth’s ocean currents
Deep-sea currents, which alternate between stronger and weaker phases, significantly impact sediment accumulation on the ocean floor.
During periods of stronger currents, often called “giant whirlpools” or eddies, these powerful movements reach the abyssal depths and erode accumulated sediment there.
The findings of a new study now shed light on how these cycles align with Earth-Mars gravitational interactions."
The claim is that this affects our temperatures on a 2.4 million year cycle.
Of course, the article insists this does nothing to raise questions about the dogma of anthropogenic global warming
