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 the Earth's main orbital parameters; precession (23 kyr), obliquity (41 kyr) and eccentricity (100 kyr). The astronomical theory of climate, in which the orbital variations are taken to drive the climate changes, has been very successful in explaining many features of the palaeoclimate records…

ABSTRACT The Pleistocene glacial cycles are the most prominent climate variations over the past three million years. They are the climatic response to variations in the incoming solar radiation,

Complex Climate Response to Astronomical Forcing: The Middle-Pleistocene Transition in Glacial Cycles and Changes in Frequency Locking

Through the past few million years large ice sheets have repeatedly grown and disappeared on the Northern hemisphere. These are the Pleistocene glaciations. They are related to the changing solar

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. The

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 the

Orbital Insolation Variations, Intrinsic Climate Variability, and Quaternary Glaciations

Abstract. The relative role of external forcing and of intrinsic variability is a key question of climate variability in general and of our planet’s paleoclimatic past in particular. Over the last

A theory of Pleistocene glacial rhythmicity

Abstract. Variations in Northern Hemisphere ice volume over the past 3 million years have been described in numerous studies and well documented. These studies depict the mid-Pleistocene transition

Quaternary glaciations: from observations to theories

The middle Pleistocene transition as a generic bifurcation on a slow manifold

The Quaternary period has been characterised by a cyclical series of glaciations, which are attributed to the change in the insolation (incoming solar radiation) from changes in the Earth’s orbit

Glacial cycles: Toward a new paradigm

The largest environmental changes in the recent geological history of the Earth are undoubtedly the successions of glacial and interglacial times. It has been clearly demonstrated that changes in the

Obliquity pacing of the late Pleistocene glacial terminations

A statistical test of the orbital forcing hypothesis is presented, focusing on the rapid deglaciation events known as terminations, and it is shown that the null hypothesis that glacial terminations are independent of obliquity can be rejected at the 5% significance level, whereas the corresponding null hypotheses for eccentricity and precession cannot be rejected.



Variability of the North Atlantic thermohaline circulation during the last interglacial period

Studies of natural climate variability are essential for evaluating its future evolution. Greenland ice cores suggest that the modern warm period (the Holocene) has been relatively stable for the

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 the

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, and

On the Structure and Origin of Major Glaciation Cycles 1. Linear Responses to Milankovitch Forcing

Time series of ocean properties provide a measure of global ice volume and monitor key features of the wind-driven and density-driven circulations over the past 400,000 years. Cycles with periods

On the Structure and Origin of Major Glaciation Cycles .2. the 100,000-year Cycle

Climate over the past million years has been dominated by glaciation cycles with periods near 23,000, 41,000, and 100,000 years. In a linear version of the Milankovitch theory, the two shorter cycles

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.

A climate model with cryodynamics and geodynamics

We present a highly simplified, zero-dimensional model of the climatic system. The model attempts to incorporate mechanisms important on the time scale of glaciation cycles, namely, 104–105 years. In

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.

Pleistocene evolution: Northern hemisphere ice sheets and North Atlantic Ocean

We analyze five high-resolution time series spanning the last 1.65 m.y.: benthic foraminiferal δ18O and δ13O, percent CaCO3, and estimated sea surface temperature (SST) at North Atlantic Deep Sea
