Using statistical methods we have shown quantitatively that the transition in mean and variance observed inδ18O records during the middle of the Pleistocene was abrupt. By applying these methods to all of the available records spanning the entire Pleistocene it appears that this jump was global and primarily represents an increase in ice mass. At roughly the same time an abrupt decrease in sea surface temperature also occurred, indicative of sudden global cooling. This kind of evidence suggests… Expand
Exploring the structure of the mid-Pleistocene revolution with advanced methods of time-series analysis
Abstract The mid-Pleistocene climate transition is a complex global change leading to Late Pleistocene ice ages with increased mean ice volume and dominant 100-ka cycle. A thorough understanding ofExpand
Gradual and abrupt changes during the Mid-Pleistocene Transition
Abstract During the Mid-Pleistocene Transition (MPT), the dominant glacial-interglacial cyclicity as inferred from the marine δ 18 O records of benthic foraminifera (δ 18 O benthic ) changed from 41Expand
A low‐order dynamical model of global climatic variability over the full Pleistocene
A previously formulated dynamical model of the late Pleistocene ice ages (based on the hypothesis that the global CO{sub 2} system can provide the instability to drive a natural oscillation involvingExpand
The Mid-Pleistocene climate transition: onset of 100 ka cycle lags ice volume build-up by 280 ka
The Mid-Pleistocene Climate Transition (MPT) is the complex climatic change which brought the Late Pleistocene ice ages. We explore the MPT in the time and frequency domains by new methods of timeExpand
Plio-Pleistocene time evolution of the 100-kyr cycle in marine paleoclimate records
To constrain theories for the dynamic evolution of global ice mass through the late Neogene, it is important to determine whether major changes in the record were gradual or rapid. Of particularExpand
The Mid-Pleistocene Transition induced by delayed feedback and bistability
The Mid-Pleistocene Transition, the shift from 41 kyr to 100 kyr glacial-interglacial cycles that occurred roughly 1 Myr ago, is often considered as a change in internal climate dynamics. Here weExpand
Early–Middle Pleistocene transitions: Linking terrestrial and marine realms
Abstract Marked by a progressive increase in the amplitude of climate oscillations, an evolving waveform, and a shift towards a quasi-100 ky frequency, the Early–Middle Pleistocene transition (EMPT),Expand
A first-order global model of late Cenozoic climatic change II. Further analysis based on a simplification of CO2 dynamics
A model developed recently for the long-term variations of global ice mass, carbon dioxide, and mean ocean temperature through the late Cenozoic is simplified by hypothesizing a new equation for theExpand
Analysis of the probability distribution of the late Pleistocene climatic record implications for model validation
Some statistical properties of the late Pleistocene climatic changes, as inferred from the analysis of the Probability Density Function (PDF) of the deep-sea δ18O record, are discussed. Estimates ofExpand
A study of the climatic regimes of the Pleistocene using a stochastic resonance model
A global energy balance model employing the stochastic resonance mechanism, previously used to explain the climatic variability of the late Pleistocene, has now been extended to account for theExpand


Abstract In the later part of the Pleistocene, variations in global ice volume have been dominated by an approximate 100,000-year cycle. Analysis of 2-Myr-long oxygen isotope record from anExpand
The Mid-Quaternary Climatic Transition as the Free Response of a Three-Variable Dynamical Model
Abstract A simplified version of a previously described dynamical model governing global ice mass, atmospheric carbon dioxide, and mean ocean temperature (that may also be a proxy for some otherExpand
Matuyama 41,000-year cycles: North Atlantic Ocean and northern hemisphere ice sheets
Abstract During the middle Pleistocene, a change occurred in the climatic response of northern hemisphere ice sheets and the high-latitude North Atlantic Ocean to orbitally controlled variations inExpand
The Late Quaternary Glaciations as the Response of a Three-Component Feedback System to Earth-Orbital Forcing.
Abstract A climatic feedback system previously described, consisting of three prognostic nonlinear equations governing the mass of ice sheets ζ, the mass of marine and continental marginal ice χ, andExpand
Climatic evolution of the mediterranean sea during the last 5.0 million years
Abstract Planktonic foraminifera from DSDP Sites 125 and 132 have been used to monitor the climatic evolution of the eastern and western Mediterranean during the last 5.0 million years. By assumingExpand
The development of antarctic glaciation and the Neogene paleoenvironment of the Maurice Ewing Bank
Abstract A micropaleontologic, magnetostratigraphic, and sedimentologic analysis of 56 piston cores provides the basis of a geologic study of the late Miocene to Holocene depositional and erosionalExpand
Climate Change in the North Pacific Using Ice-Rafted Detritus as a Climatic Indicator
The variations in weight percent of the grain size fraction greater than 250 μ in nine cores from the North Pacific were determined using sampling intervals of 5 to 20 cm. Material in this sizeExpand
Paleomagnetic stratigraphy and micropaleontology of three deep sea cores from the Central North Atlantic Ocean
Abstract The paleomagnetic stratigraphy of 3 deep sea cores from the central North Atlantic ocean indicates that sediments as old as 2 m.y. were recovered. In one of the cores, CHAIN 61 (171), theExpand
Pleistocene Sedimentation in the Equatorial Atlantic: Stratigraphy and Faunal Paleoclimatology
