The attraction of Jupiter and Venus on Earth causes important climatic events

The orbit of the Earth around the sun is almost perfectly circular. That is, except every 405,000 years, when the massive gravitational pull of Jupiter and Venus pulls Earth’s orbit in an ellipse of about 5 °, producing the Milankovitch cycles that cause the glacial and interglacial cycles of the planet. “Scientists can now link the changes in climate, the environment, dinosaurs, mammals and fossils from around the world to this 405,000-year cycle in a very precise way,” says geomagnetic researcher Dennis V. Kent of Rutgers University, who has documented this periodic deformation of our orbit. Before someone starts jumping from side to side screaming, “Yes, climate change is not our fault”, keep in mind that the temperature cycles through which Jupiter and Venus can be responsible happen for a very long time, extending before arriving here and continuing later. Orbital remodeling is “very low on the list of so many other things that can affect climate on time scales that matter to us,” says Kent.
This gravitational effect has been suspected for some time, but never goes back to the new research: 215 million years. “It’s a surprising result because this long cycle, which had been predicted from planetary movements about 50 million years ago, has been confirmed at least 215 million years ago,” Kent explains to Rutgers Today. Kent and his colleagues discovered the pattern as they dug into Arizona’s Petrified Forest National Park for evidence of magnetic polarity reversals in Earth’s past. A core, in particular, taken from the Chinle Formation, was 1,700 feet long, and dated back to the Triassic era from 202 to 253 million years ago. When they compared the 2.5-inch-diameter core with others extracted from the Newark Newark In the basin, they found a series of patterns that aligned with the orbits of the Earth’s sun, but one demanded their attention: it occurred every 405,000 years. “There are other shorter orbital cycles, but when you look at the past, it is very difficult to know which one you are dealing with at any given moment, because they change over time,” Kent explains, but the “beauty of this is that he is alone. Everyone else moves on him. ” Explaining the climatic ramifications of his discovery, Kent says: “Climatic cycles are directly related to the Earth’s orbit over the Sun and small variations in sunlight that reach Earth cause climate and ecological changes.” it only has a 5 ° deformation, but it is enough to feel its impact and leave a signature behind. And it is surprising that the celestial bodies so far away (Jupiter is 588 million kilometers from Earth and Venus has 261 million) can affect our climate.
