The Miocene is characterized by a series of key climatic events that led to the founding of the late Cenozoic icehouse mode and the dawn of modern biota. The processes that caused these developments, and particularly the role of atmospheric CO2 as a forcing factor, are poorly understood. Here we present a CO2 record based on stomatal frequency data from multiple tree species. Our data show striking CO2 fluctuations of ≈600–300 parts per million by volume (ppmv). Periods of low CO2 are…

Effects of CO 2 , continental distribution, topography and vegetation changes on the climate at the Middle Miocene: a model study

Abstract. The Middle Miocene was one of the last warm periods of the Neogene, culminating with the Middle Miocene Climatic Optimum (MMCO, approximatively 17–15 Ma). Several proxy-based

Growth of subtropical forests in Miocene Europe: The roles of carbon dioxide and Antarctic ice volume

The middle Miocene is a crucial period for the evolution of apes, and it corresponds to their appearance in Europe. The dispersion of apes was made possible by tectonic changes and the expansion of

Middle Miocene climate instability associated with high‐amplitude CO2 variability

The amplitude of climatic change, as recorded in the benthic oxygen isotope record, has varied throughout geological time. During the late Pleistocene, changes in the atmospheric concentration of

Late Miocene cooling coupled to carbon dioxide with Pleistocene-like climate sensitivity

Earth’s climate cooled markedly during the late Miocene from 12 to 5 million years ago, with far-reaching consequences for global ecosystems. However, the driving forces of these changes remain

Atmospheric carbon dioxide variations across the middle Miocene climate transition

Abstract. The middle Miocene climate transition ∼  14 Ma marks a fundamental step towards the current “ice-house” climate, with a ∼  1 ‰ δ18 O increase and a ∼  1 ‰ transient δ13 C rise in the deep

Global perturbation of the carbon cycle at the onset of the Miocene Climatic Optimum

The Miocene Climatic Optimum (MCO; ca. 17-14.7 Ma) represents one of several major interruptions in the long-term cooling trend of the past 50 m.y. To date, the processes driving high-amplitude

New data are presented that overturns the notion that other radiative forcings such as changes in paleogeography or meridional heat transport were disproportionately more important than CO2 at this time and provide important insights into the climatic linkages during this Epoch.

Climate-vegetation modelling and fossil plant data suggest low atmospheric CO 2 in the late Miocene

Abstract. There is an increasing need to understand the pre-Quaternary warm climates, how climate–vegetation interactions functioned in the past, and how we can use this information to understand the

Climatic Controls on C4 Grassland Distributions During the Neogene: A Model-Data Comparison

Grasslands dominated by taxa using the C4 photosynthetic pathway evolved on several continents during the Neogene and Quaternary, long after C4 photosynthesis first evolved among grasses. The

Eccentricity-paced atmospheric carbon-dioxide variations across the middle Miocene climate transition

Abstract. The middle Miocene climate transition ~ 14 Ma marks a fundamental step towards the current “icehouse” climate, with a ~ 1 ‰ δ18O increase and a ~ 1 ‰ transient δ13C rise in the deep ocean,



Impacts of orbital forcing and atmospheric carbon dioxide on Miocene ice-sheet expansion

It is surmised that the thermal isolation of Antarctica played a role in providing sustained long-term climatic boundary conditions propitious for ice-sheet formation, and relatively constant, low summer insolation over Antarctica coincident with declining atmospheric carbon dioxide levels at the time of Antarctic ice- sheet expansion and global cooling, suggesting a causal link.

Atmospheric carbon dioxide concentrations over the past 60 million years

The boron-isotope ratios of ancient planktonic foraminifer shells are used to estimate the pH of surface-layer sea water throughout the past 60 million years, which can be used to reconstruct atmospheric CO2 concentrations.

CO2-Forced Climate and Vegetation Instability During Late Paleozoic Deglaciation

Major restructuring of paleotropical flora in western Euramerica occurred in step with climate and pCO2 shifts, illustrating the biotic impact associated with past CO2-forced turnover to a permanent ice-free world.

Miocene evolution of atmospheric carbon dioxide

Changes in pCO2 or ocean circulation are generally invoked to explain warm early Miocene climates and a rapid East Antarctic ice sheet (EAIS) expansion in the middle Miocene. This study reconstructs

Marked Decline in Atmospheric Carbon Dioxide Concentrations During the Paleogene

Stable carbon isotopic values of di-unsaturated alkenones extracted from deep sea cores are used to reconstruct pCO2 from the middle Eocene to the late Oligocene and demonstrate that it ranged between 1000 to 1500 parts per million by volume in the middle to late Eocene, then decreased in several steps during theOligocene, and reached modern levels by the latest Oligaen.

Stable Carbon Cycle–Climate Relationship During the Late Pleistocene

A record of atmospheric carbon dioxide concentrations measured on the EPICA (European Project for Ice Coring in Antarctica) Dome Concordia ice core extends the Vostok CO2 record back to 650,000 years before the present, suggesting that the relationship between CO2 and Antarctic climate remained rather constant over this interval.

Paleobotanical evidence for near present-day levels of atmospheric Co2 during part of the tertiary.

This reconstruction indicates that CO(2) remained between 300 and 450 parts per million by volume for these intervals with the exception of a single high estimate near the Paleocene/Eocene boundary, and suggests that factors in addition to CO( 2) are required to explain these past intervals of global warmth.

Coupling of surface temperatures and atmospheric CO2 concentrations during the Palaeozoic era

Estimates of sea surface temperatures that were obtained from fossil brachiopod and mollusc shells using the ‘carbonate clumped isotope’ method are presented, consistent with the proposal that increased atmospheric carbon dioxide concentrations drive or amplify increased global temperatures.

Global vegetation change through the Miocene/Pliocene boundary

Between 8 and 6 million years ago, there was a global increase in the biomass of plants using C4 photosynthesis as indicated by changes in the carbon isotope ratios of fossil tooth enamel in Asia,
