A 13-million-year continuous record of Oligocene climate from the equatorial Pacific reveals a pronounced “heartbeat” in the global carbon cycle and periodicity of glaciations. This heartbeat consists of 405,000-, 127,000-, and 96,000-year eccentricity cycles and 1.2-million-year obliquity cycles in periodically recurring glacial and carbon cycle events. That climate system response to intricate orbital variations suggests a fundamental interaction of the carbon cycle, solar forcing, and… 

Orbital pacing of carbon fluxes by a ∼9-My eccentricity cycle during the Mesozoic

Analysis of stable isotope fluctuations recorded by fossil cephalopods throughout the Jurassic–Early Cretaceous interval documents a prominent cyclicity of ∼9 My in the carbon cycle paced by changes in the seasonal dynamics of hydrological processes and long-term sea level fluctuations, an important metronome of the greenhouse climate dynamics.

Persistent 400,000-year variability of Antarctic ice volume and the carbon cycle is revealed throughout the Plio-Pleistocene.

This simulation of global ice volume over the past 5 million years with a coupled system of four three-dimensional ice-sheet models shows that the 400,000-year long eccentricity cycles of Antarctica vary coherently with δ(13)C data during the Pleistocene, suggesting that they drove the long-term carbon cycle changes throughout the past 35 million years.

The Plio-Pleistocene climatic evolution as a consequence of orbital forcing on the carbon cycle

Abstract. Since the discovery of ice ages in the 19th century, a central question of climate science has been to understand the respective role of the astronomical forcing and of greenhouse gases, in

Precessional pacing of tropical ocean carbon export during the Late Cretaceous

. The marine biological carbon pump, which exports organic carbon out of the surface ocean, plays an essential role in sequestering carbon from the atmosphere, thus impacting climate and affecting

A 100 Myr history of the carbon cycle based on the 400 kyr cycle in marine δ13C benthic records

Documenting the past coevolution of Earth temperatures and of the carbon cycle is of paramount importance for our understanding of climate dynamics. Atmospheric CO2 is well constrained over the last

Orbital pacing and secular evolution of the Early Jurassic carbon cycle

The Mochras δ 13CTOC record illustrates the continued impact of long-eccentricity orbital forcing on the carbon cycle over at least ∼18 My of Early Jurassic time and emphasizes orbital forcing as a driving mechanism behind medium-amplitude δ13C fluctuations superimposed on larger-scale trends that are driven by other variables such as tectonically determined paleogeography and eruption of large igneous provinces.

Climate Response to Orbital Forcing Across the Oligocene-Miocene Boundary

A major transient glaciation at the epoch boundary of late Oligocene–early Miocene climate and ocean carbon chemistry from two deep-sea cores recovered in the western equatorial Atlantic corresponds with a rare orbital congruence involving obliquity and eccentricity, resulting in an extended period of low seasonality orbits favorable to ice-sheet expansion on Antarctica.

Rapid Cenozoic glaciation of Antarctica induced by declining atmospheric CO2

In this simulation, declining Cenozoic CO2 first leads to the formation of small, highly dynamic ice caps on high Antarctic plateaux, and at a later time, a CO2 threshold is crossed, initiating ice-sheet height/mass-balance feedbacks that cause the ice caps to expand rapidly with large orbital variations, eventually coalescing into a continental-scale East Antarctic Ice Sheet.

The 100,000-year ice-Age cycle identified and found to lag temperature, carbon dioxide, and orbital eccentricity

At the 100,000-year period, atmospheric carbon dioxide, Vostok air temperature, and deep-water temperature are in phase with orbital eccentricity, whereas ice volume lags these three variables, and it is probably the response of the global carbon cycle that generates the eccentricity signal by causing changes in Atmospheric carbon dioxide concentration.
