Earth’s Orbital Changes Have Influenced Climate, Life Forms For at Least 215 Million Years

Rutgers University-New Brunswick

Every 405,000 years, gravitational tugs from Jupiter and Venus slightly elongate Earth’s orbit, an amazingly consistent pattern that has influenced our planet’s climate for at least 215 million years and allows scientists to more precisely date geological events like the spread of dinosaurs, according to a Rutgers-led study. The findings are published online today in the Proceedings of the National Academy of Sciences.
