    Hypotheses to explain the origin of species in Amazonia by J. Haffer

    “…The basic paleogeography model refers mainly to faunal differentiation during the Tertiary and in combination with the Refuge hypothesis. Milankovitch cycles leading to global climatic-vegetational changes affected the biomes of the world not only during the Pleistocene but also during the Tertiary and earlier geological periods. …”

    Subsidence of the Laguna Salada Basin, northeastern Baja California, Mexico, inferred from Milankovitch climatic changes by Juan Carlos Herguera, Arturo Martín-Barajas, Juan Contreras

    Published 2005-04-01
    “…The power spectrum of the gamma-ray log resembles the spectrum of δ18O Pleistocene isotopic variations from ice cores and from the deep ocean, known to be strongly controlled by Milankovitch cycles. We correlate δ18O stages with silty and sandy intervals in the log. …”

    Deep-sea hiatus record reveals orbital pacing by 2.4 Myr eccentricity grand cycles by Adriana Dutkiewicz, Slah Boulila, R. Dietmar Müller

    Published 2024-03-01
    “…Abstract Astronomical forcing of Earth’s climate is embedded in the rhythms of stratigraphic records, most famously as short-period (104–105 year) Milankovitch cycles. Astronomical grand cycles with periods of millions of years also modulate climate variability but have been detected in relatively few proxy records. …”

    On Time Scales of Intrinsic Oscillations in the Climate System by Anastasios A. Tsonis, Geli Wang, Wenxu Lu, Sergey Kravtsov, Christopher Essex, Michael W. Asten

    Published 2021-04-01
    “…We find the existence of a striking gap from ~1000 to about ~20,000 years, which separates intrinsic climatic oscillations with periods ranging from ~60 years to ~1000 years, from the longer time-scale periodicities (20,000 year+) involving external forcing associated with Milankovitch cycles. The absence of natural oscillations with periods within the gap is consistent with cumulative evidence based on past data analyses, as well as with earlier theoretical and modeling studies.…”

    Functionality of Ice Line Latitudinal EBM Tenacity (FILLET). Protocol Version 1.0. A CUISINES Intercomparison Project by Russell Deitrick, Jacob Haqq-Misra, Shintaro Kadoya, Ramses Ramirez, Paolo Simonetti, Rory Barnes, Thomas J. Fauchez

    Published 2023-01-01
    “…Because EBMs are far less computationally intensive than 3D general circulation models (GCMs), they can be run over large uncertain parameter spaces and can be used to explore long-period phenomena, like carbon and Milankovitch cycles. Because horizontal dimensions are incorporated in EBMs, they can explore processes that are beyond the reach of 1D radiative-convective models (RCMs). …”
