Evaluating alternatives to the Milankovitch theory
Journal of Statistical Planning and Inference, 2016 The physical process that causes cycles in Earth’s precession, obliquity, and eccentricity is well established, and researchers have detected and modeled the orbital cycles for millions of years into the past.

Toward generalized Milankovitch theory (GMT) [PDF]
Climate of the PastIn recent decades, numerous paleoclimate records and results of model simulations have provided strong support for the astronomical theory of Quaternary glacial cycles formulated in its modern form by Milutin Milankovitch.

The Dependence of Earth Milankovitch Cycles on Martian Mass [PDF]
Publications of the Astronomical Society of the PacificAbstract The Milankovitch cycles of Earth result from gravitational interactions with other bodies in the solar system. These interactions lead to slow changes in the orbit and angular momentum vector of Earth, and correspondingly influence Earth’s climate evolution. Several studies have shown that Mars may play a

GENERALIZED MILANKOVITCH CYCLES AND LONG-TERM CLIMATIC HABITABILITY [PDF]
The Astrophysical Journal, 2010 Although the Earth's orbit is never far from circular, terrestrial planets around other stars might experience substantial changes in eccentricity that could lead to climate changes, including possible "phase transitions" such as the snowball transition (or its opposite).

Millennial-scale climate cycles modulated by Milankovitch forcing in the middle Cambrian (ca. 500 Ma) Marjum Formation, Utah, USA [PDF]
GeologyMiddle Cambrian offshore deposits of the Marjum Formation, Utah, USA, are characterized by four scales of superimposed cyclicity defined by varying fine siliciclastic versus limestone abundances; these include limestone-marl couplets (rhythmites; 5−10 cm)

Orbital eccentricity and internal feedbacks drove the Triassic megamonsoon variability [PDF]
Scientific ReportsThe evolution of the Triassic megamonsoon was closely linked to Earth’s orbital variations. Despite recognizing secular orbital cycles as a fundamental pacemaker of the megamonsoon, the driving mechanisms remain unclear. Here, we use data-model synthesis

The Effect of Additive and Multiplicative Cyclic Perturbations on Noise-Induced Tipping Dynamics [PDF]
EntropyThe dynamics of systems near tipping points attract considerable attention in the context of climate change, ecological regime shifts, disease spreading, and other complex systems undergoing transitions.

Decadal–centennial-scale solar-linked climate variations and millennial-scale internal oscillations during the Early Cretaceous [PDF]
Scientific Reports, 2022 Understanding climate variability and stability under extremely warm ‘greenhouse’ conditions in the past is essential for future climate predictions. However, information on millennial-scale (and shorter) climate variability during such periods is scarce,
