Exponential feedback effects in a parametric resonance climate model [PDF]

open access: yesScientific Reports, 2023
The variations in the distribution of solar radiation due to the  ~ 105 years Milankovitch cycle, which is connected to the Earth eccentricity variation, cannot explain the sharp drop in temperature of 6 °C ÷ 10 °C that marks the transition from the ...

Characteristics of Milankovitch cycles recorded in Eocene strata in the eastern depression of North Yellow Sea Basin, North China

open access: yesChina 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.

Proterozoic Milankovitch cycles and the history of the solar system [PDF]

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2018
Significance Periodic variations in Earth’s orbit and rotation axis occur over tens of thousands of years, producing rhythmic climate changes known as Milankovitch cycles. The geologic record of these climate cycles is a powerful tool for reconstructing geologic time, for understanding ancient climate change, and for evaluating the ...

Pacing of Paleozoic macroevolutionary rates by Milankovitch grand cycles [PDF]

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2018
Significance There 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%

When volcanoes record Milankovitch cycles

open access: yesFrontiers in Earth Science
Cyclic fluctuations in the frequency and intensity of volcanic activity are recorded during periods of global climate change. Volcano-sedimentary successions (e.g., in near-coastal environments) may reveal the interplay of glacio-eustatic fluctuations ...

A method for the division of the conglomerate depositional cycle under Milankovitch cycles [PDF]

open access: yesJournal of Geophysics and Engineering, 2017
The conglomerate layer at the upper section of the 4th member of the Shahejie formation of the Yongan district at the Donying depression is a well-developed sedimentation of several periods. It lacks stable muddy layers and sophisticated classification of the sedimentation periods and the proportion of sedimentary layering in each period has long been ...

Orbital eccentricity and internal feedbacks drove the Triassic megamonsoon variability [PDF]

open access: yesScientific Reports
The 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]

open access: yesEntropy
The 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]

open access: yesScientific 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,

Uniformity of the upper Famennian Milankovitch cycle in China

open access: yesScience Bulletin, 2000
Research on chemo-biostratigraphy reveals that the periodic fluctuation of Ce/La ratios in carbonate sequence may reflect Milankovitch 100 ka eccentricity cyclicity. The Ce/La curve of the upper Famennian of Huangmao (Guangxi) may be well correlated to that of Muhua (Guizhou) and of Mid-Tarim (Xinjiang).
