In 405,000-year cycles, the tug of nearby planets causes hotter summers, colder winters and drier droughts on our home planet
Astronomers 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. But they lacked much physical evidence of this process—and have long debated the particulars of the effects. 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.
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. However, they lacked the ability to precisely date those climatic shifts. The Arizona core, however, contain layers of ash from volcanic eruptions that could be dated because it contains radioisotopes.
The researchers aligned the Arizona core dates to the ancient lake cores using bands found in all of the cores, marking reversals in Earth’s magnetic fields. This allowed them to compare the records. The analysis demonstrated that the climate swings took place every 405,000 years for at least the last 215 million years, or through the Late Triassic age when dinosaurs roamed the Earth.

The planets are not real and are only metaphoric representations of blah blah..blah blah. I just don't even feel like bothering anymore.

Interesting thread, thanks for sharing.
Not surprised to learn this happens but never really gave it any thought.
Kinda cool.

The other planets can effect what happens here on earth, but it would be hard to know for sure how it would effect climate. Maybe in fifty more years of observations they may figure it out better.

It'll probably be 100 years from now when people will be laughing saying, "they sure were stupid back in the early 2000's when those silly citizens let their governments and scientists talk them into solving climate change through taxes and carbon credits".

Half the people are laughing at it now, but laughing will not stop them from collecting taxes from us, making it sound like it is necessary to add taxes so people do not travel as much. Most fuels are used on going back and forth to work and to haul commerce all over the world. Raising prices of everything is not going to do the trick, they still want us to keep buying the junk, they are not going to increase the longlivity of things we buy or stop the planned obsollescence, that would disrupt the taxes they collect from workers and sales and import taxes. They just want us to pay more taxes.

Which brings us to yet another problem - trash! Out of sight, out of mind apparently. The older I get, the more I care about the trash I produce. Population keeps increasing and the garbage dumps are getting taller. Plastic is, by far, the most plentiful thing I throw away. And to think, it came from oil.

So why are Venus and Jupiter so influential on our orbit? Venus’s tug is so strong because it’s our closest planetary neighbor, approaching as close as 24 million miles. The sheer size of Jupiter—which is roughly 318 times as massive as Earth—means it also has an outsized pull on our planet. At the peak of that warped orbit, Earth undergoes hotter summers, colder winters as well as more intense periods of drought and wetness.
Knowing how this cycle works could impact on our understanding of past climate change and the arrival and disappearance of plant and animal species. “Scientists can now link changes in the climate, environment, dinosaurs, mammals and fossils around the world to this 405,000-year cycle in a very precise way," lead author Dennis Kent, an expert in paleomagnetism at Columbia University and Rutgers tells Doyle Rice at USA Today. “The climate cycles are directly related to how the Earth orbits the sun and slight variations in sunlight reaching Earth lead to climate and ecological changes.”

"This is truly complicated stuff," said Olsen. "We are using basically the same kinds of math to send spaceships to Mars, and sure, that works. But once you start extending interplanetary motions back in time and tie that to cause and effect in climate, we can't claim that we understand how it all works."

Interesting article thanks for the post.
Somehow people still managed to warp the discussion into taxes. Seriously taxes? is that what keeps you up all night?
Can't have a discussion about anything on this site anymore without it devolving into some government conspiracy.
