Stochastic Resonance Elucidates the Emergence and Periodicity Transition of Glacial Cycles
Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.Abstract Glacial cycles emerged with a 41‐kyr period after the Pliocene and later intensified with a 100‐kyr period in the mid‐Pleistocene, which were attributed to Earth's orbital variations. However, no significant changes in the orbital forcing were found at the two transitions, and the forcing was too small to drive these cycles. Here, a stochastic

A spring forward for hominin evolution in East Africa. [PDF]
PLoS ONE, 2014 Groundwater is essential to modern human survival during drought periods. There is also growing geological evidence of springs associated with stone tools and hominin fossils in the East African Rift System (EARS) during a critical period for hominin ...

Molecular Ecology, Volume 35, Issue 2, January 2026.ABSTRACT Arctic‐alpine species are highly sensitive to long‐term temperature changes and associated glacial cycles due to their occurrence in cold environments to which they are adapted and spatially restricted. Unravelling their evolutionary responses to past climatic fluctuations can provide new insights into their diversification.

Self-sustained oscillations and global climate changes
Scientific Reports, 2020 The periodic changes of atmospheric CO2 and temperature over the last 5 Myr reveal three features that challenge current climate research, namely: (i) the mid-Pleistocene transition of dominant 41-kyr cycles to dominant 100-kyr cycles, (ii) the absence ...

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.Abstract The collision of continents typically leads to orogenesis as a result of crustal thickening and isostatic compensation. High topography is a main locus of precipitation‐fueled erosion, providing a feedback‐loop between tectonics, surface processes, and climate.

Bifurcations and strange nonchaotic attractors in a phase oscillator model of glacial-interglacial cycles [PDF]
, 2015 Glacial-interglacial cycles are large variations in continental ice mass and greenhouse gases, which have dominated climate variability over the Quaternary.

Evolution of Terrestrial Planetary Bodies and Implications for Habitability
Reviews of Geophysics, Volume 63, Issue 4, December 2025.Abstract The terrestrial planetary bodies of our solar system—Mercury, Venus, Earth, and Mars—share a common origin through nebular accretion and early magma ocean differentiation, yet they diverged significantly in geological evolution, tectonic regimes, and habitability.

Fifth-order cyclicity and organic matter contents relationship (Lower Eocene, Pyrenees)
Geologica Acta, 2007 The Upper Limestone Member of the Corones Formation of the Spanish Pyrenees consists of various units (Lower and the Upper Foraminifera Units, Shale Unit, Cherty-ostracode Unit, Ostracode Unit and Chara-ostracode Unit) and offers strong facies and ...

Dynamics between order and chaos in conceptual models of glacial cycles
, 2013 The dynamics of glacial cycles is studied in terms of the dynamical systems theory. We explore the dependence of the climate state on the phase of astronomical forcing by examining five conceptual models of glacial cycles proposed in the literature.
