Milankovitch cycles in banded iron formations constrain the Earth-Moon system 2.46 billion years ago. [PDF]
Proc Natl Acad Sci U S A, 2022 Significance Milankovitch cycles recorded in 2.46-billion-year-old sediments indicate that Earth’s precession cycle had a significantly higher frequency than present, signaling shorter daylengths and Earth–Moon distance.

China Geology, 2021 As cyclical orbital movements of Earth, Milankovitch cycles can be recorded in sedimentary strata. The time they reflect can be used to accurately divide and compare strata.

Climate, 2021 Recent decades have registered the hottest temperature variation in instrumentally recorded data history. The registered temperature rise is particularly significant in the so-called hot spot or sentinel regions, characterized by higher temperature ...

Milankovitch cycles for a circumstellar Earth-analog within α Centauri-like binaries [PDF]
Monthly Notices of the Royal Astronomical Society, 2021 Abstract An Earth-analog orbiting within the habitable zone of α Centauri B was shown to undergo large variations in its obliquity, or axial tilt, which affects the planetary climate by altering the radiative flux for a given latitude. We examine the potential implications of these obliquity variations for climate through Milankovitch ...

Earth Orbit v2.1: a 3-D visualization and analysis model of Earth's orbit, Milankovitch cycles and insolation [PDF]
Geoscientific Model Development, 2014 Milankovitch theory postulates that periodic variability of Earth's orbital elements is a major climate forcing mechanism, causing, for example, the contemporary glacial–interglacial cycles.

Open Geosciences, 2019 Logs in the petroleum boreholes indirectly records the sedimentary cycles in the deep burial formation. In order to extract and understand the periodicity and cyclicity, it is necessary to process the data by digital signal analysis method.

Exo-Milankovitch Cycles. I. Orbits and Rotation States [PDF]
The Astronomical Journal, 2018 Abstract The obliquity of the Earth, which controls our seasons, varies by only ∼2.°5 over ∼40,000 years, and its eccentricity varies by only ∼0.05 over 100,000 years. Nonetheless, these small variations influence Earth’s ice ages. For exoplanets, however, variations can be significantly larger.

Pacing of Paleozoic macroevolutionary rates by Milankovitch grand cycles [PDF]
Proceedings of the National Academy of Sciences, 2018 SignificanceThere has been long-standing debate about the relative roles of intrinsic biotic interactions vs. extrinsic environmental factors as drivers of biodiversity change. Here, we show that, relatively early in the history of complex life, Milankovitch “grand cycles” associated with astronomical rhythms explain between 9 and 16% of variation in ...
