Mars Strongly Influences Earth's Long-Term Climate
Scientists have discovered that Mars has a much bigger effect on Earth's climate than we thought.
Mars' gravity helps control Earth's tilt and orbit, which affects long-term climate cycles that last hundreds of thousands to millions of years.
These cycles can cause ice ages and other big climate changes.
Before, scientists thought Venus and Jupiter were the main planets affecting these cycles, but now they know Mars plays a big role too.
Mars helps keep Earth's tilt stable and makes some important climate cycles possible.
Without Mars, these cycles wouldn't exist, and Earth's climate would be very different.
Mars' gravity significantly influences Earth's tilt and orbit, affecting long-term climate cycles.
Milankovitch cycles, which control Earth's climate over millions of years, are impacted by Mars' gravitational pull.
Removing Mars from simulations eliminated two important climate cycles with periods of 100,000 and 2.4 million years.
Mars helps stabilize Earth's tilt, which fluctuates between 21.5 and 24.5 degrees every 41,000 years.
Mars' influence on Earth's climate is greater than expected due to its position in the solar system.
