Obliquity pacing of the late Pleistocene glacial terminations

  title={Obliquity pacing of the late Pleistocene glacial terminations},
  author={P. Huybers and C. Wunsch},
The 100,000-year timescale in the glacial/interglacial cycles of the late Pleistocene epoch (the past ∼700,000 years) is commonly attributed to control by variations in the Earth's orbit. This hypothesis has inspired models that depend on the Earth's obliquity (∼ 40,000 yr; ∼40 kyr), orbital eccentricity (∼ 100 kyr) and precessional (∼ 20 kyr) fluctuations, with the emphasis usually on eccentricity and precessional forcing. According to a contrasting hypothesis, the glacial cycles arise… Expand
Obliquity and precession as pacemakers of Pleistocene deglaciations
Abstract The Milankovitch theory states that the orbital eccentricity, precession, and obliquity of the Earth influence our climate by modulating the summer insolation at high latitudes in theExpand
A conceptual model for glacial cycles and the middle Pleistocene transition
Milankovitch’s astronomical theory of glacial cycles, attributing ice age climate oscillations to orbital changes in Northern-Hemisphere insolation, is challenged by the paleoclimatic record. TheExpand
Combined obliquity and precession pacing of the late Pleistocene glacial cycles
Milankovitch postulated that deglaciation occurs when Earth’s obliquity is high and precession brings Earth’s eccentric orbit near the sun during Northern summer, and this general concept has beenExpand
The role of orbital forcing in the Early Middle Pleistocene Transition
Abstract The Early Middle Pleistocene Transition (EMPT) is the term used to describe the prolongation and intensification of glacial–interglacial climate cycles that initiated after 900,000 yearsExpand
Combined obliquity and precession pacing of late Pleistocene deglaciations
Deficiencies in time control that have long stymied efforts to establish orbital effects on deglaciation are overcome using a new statistical test that focuses on maxima in orbital forcing. Expand
Evidence for Obliquity Forcing of Glacial Termination II
A new speleothem-based North Atlantic marine chronology is presented that shows that the penultimate glacial termination commenced 141,000 ± 2500 years before the present, too early to be explained by Northern Hemisphere summer insolation but consistent with changes in Earth’s obliquity. Expand
Changing climatic response: a conceptual model for glacial cycles and the Mid-Pleistocene Transition
Abstract. Milankovitch's astronomical theory of glacial cycles, attributing ice age climate oscillations to orbital changes in Northern Northern-Hemisphere insolation, is challenged by theExpand
Links between eccentricity forcing and the 100,000-year glacial cycle
The 100,000-year glacial cycles are generally thought to be driven by the eccentricity of the Earth’s orbit. Statistical analyses of climate variability and orbital forcing over the past five millionExpand
Mid-Pleistocene revolution and the ‘eccentricity myth’
Abstract The mid-Pleistocene revolution (MPR) is the term used to describe the transition between 41 ka and 100 ka glacial-interglacial cycles which occurred about one million years ago. DespiteExpand
The Southern Glacial Maximum 65,000 years ago and its Unfinished Termination
Abstract Glacial maxima and their terminations provide key insights into inter-hemispheric climate dynamics and the coupling of atmosphere, surface and deep ocean, hydrology, and cryosphere, which isExpand


The timing of Pleistocene glaciations from a simple multiple-state climate model
The Earth's climate over the past million years has been characterized by a succession of cold and warm periods, known as glacial–interglacial cycles, with periodicities corresponding to those of theExpand
The timing of major climate terminations
A simple, untuned “constant sedimentation rate” timescale developed using three radiometric age constraints and eleven δ18O records longer than 0.8 Myr provides strong support for the validity of theExpand
The 41 kyr world: Milankovitch's other unsolved mystery
[1] For most of the Northern Hemisphere Ice Ages, from ∼3.0 to 0.8 m.y., global ice volume varied predominantly at the 41,000 year period of Earth's orbital obliquity. However, summer (or summerExpand
Orbital insolation, ice volume, and greenhouse gases.
Abstract The SPECMAP models of orbital-scale climate change (Imbrie et al., Paleoceanography 7 (1992) 701, Paleoceanography 8 (1993) 699) are the most comprehensive to date: all major climaticExpand
Modeling the Climatic Response to Orbital Variations
This article summarizes how the theory has evolved since the pioneer studies of James Croll and Milutin Milankovitch, reviews recent evidence that supports the theory, and argues that a major opportunity is at hand to investigate the physical mechanisms by which the climate system responds to orbital forcing.

Quantitative estimate of the Milankovitch-forced contribution to observed Quaternary climate change
A number of records commonly described as showing control of climate change by Milankovitch insolation forcing are reexamined. The fraction of the record variance attributable to orbital changesExpand
Variations in the Earth's Orbit: Pacemaker of the Ice Ages
It is concluded that changes in the earth's orbital geometry are the fundamental cause of the succession of Quaternary ice ages and a model of future climate based on the observed orbital-climate relationships, but ignoring anthropogenic effects, predicts that the long-term trend over the next sevem thousand years is toward extensive Northern Hemisphere glaciation.
