Since 65 million years ago (Ma), Earth's climate has undergone a significant and complex evolution, the finer details of which are now coming to light through investigations of deep …
Much of our understanding of Earth's past climate comes from the measurement of oxygen and carbon isotope variations in deep-sea benthic foraminifera. Yet, long intervals in …
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 …

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 …
Increasingly, environmental scientists, palaeoceanographers and geologists are collecting quantitative records of environmental changes (time series) from sediments, ice cores, cave …
An astronomically calibrated timescale has recently been established [Hilgen, 1991a, b] for the Pliocene and earliest Pleistocene based on the correlation of dominantly precession …
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 …
Spectral analyses of an uninterrupted 5.5-million-year (My)–long chronology of late Oligocene–early Miocene climate and ocean carbon chemistry from two deep-sea cores …

The upper Paleocene and lower Eocene are marked by several prominent (> 1‰) carbon isotope (δ13C) excursions (CIE) that coincide with transient global warmings, or thermal …
