![]() ![]() The Arizona core, however, contain layers of ash from volcanic eruptions that could be dated because it contains radioisotopes. However, they lacked the ability to precisely date those climatic shifts. Researchers noticed that lake sediment cores bear a regular pattern of ancient lakes drying up and refilling over the course of hundreds of thousands of years-a cycle that hints at cyclical changes in climate. The new study published in in the Proceedings of the National Academy of Sciences, demonstrates the influence of our planetary neighbor’s pull using a 1,500-foot rock core collected in 2013 from a butte in Arizona’s Petrified Forest National Park and cores from the site of ancient lake beds in New York and New Jersey. But they lacked much physical evidence of this process-and have long debated the particulars of the effects. Īstronomers have long hypothesized that other planets in our solar system have impacts here on Earth, shifting its whirl around the sun from nearly circular to five percent elliptical. ![]() As George Dvorsky reports for Gizmodo, a new study presents the first physical evidence that the Venus’ and Jupiter’s gravity can cause shifts in Earth’s orbit-and swings in its climate-every 405,000 years. ![]() And while this idea lacks scientific proof, it turns out that planetary alignments do affect some things on Earth. Astrologers have maintained for centuries that the position of the planets impact people’s personalities and emotions. ![]()
