Article
Climate Cycles (book chapter) - Milankovitch and 405-kyr Earth-Sun Cycle is a peer-reviewed textbook published by Springer Nature (book chapter) in 2024. It is a textbook chapter explaining orbital climate cycles from 23,000-100,000 years, plus a highly stable 405,000-year eccentricity cycle used for dating ancient sediments.
The analysis focuses on 23,000-100,000 years (precession/obliquity/eccentricity), and 405,000-year long eccentricity cycle stable over hundreds of millions of years. This gives the cycle claim a specific numerical and evidential setting rather than presenting periodicity only as a visual impression.
The article reports the following result: The three most important orbital cycles have periods ranging from 23,000 to 100,000 years. One very long Earth-Sun cycle, with a period of 405,000 years, has been consistent for several hundred million years. The interpretation is strongest when it survives proxy uncertainty, model choice, dating error and comparison with established solar, orbital and ocean-atmosphere forcing.
For cycles researchers, the article brings together milankovitch cycles, 405-kyr eccentricity cycle, orbital climate forcing, astrochronology. It is relevant to climate-cycle research because observed periodicities may arise from orbital forcing, solar variability, ocean-atmosphere dynamics or internal stochastic behaviour.
Because it is a peer-reviewed textbook, the article is a strong starting point for discussion in the Climate & Weather forum, although its conclusions should still be compared with later replications and updated datasets.
