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-sea sediment cores. This evolution includes gradual trends of warming and cooling driven by tectonic processes on time scales of 105to 107 years, rhythmic or periodic cycles driven by orbital processes with 104- to 106-year cyclicity, and rare rapid aberrant shifts and extreme climate transients with durations of…

One-way and quasi-periodic climate changes: Geologic evidence
During the last three billion years, the Earth has been experiencing a slow global cooling, expressed in the progressively increasing frequency and scale of glacial events. Based on these
Orbital cyclicity in climate change over the last three million years
In the Earth’s climate history, there were substantial oscillations of the climate, reliable evidence of which remained in the sea and ocean sediments and ice sheets. The current glacial period, in
Global and African Regional Climate during the Cenozoic
The last 65 Ma of Earth’s history, the Cenozoic, has been a time characterized by significant climate change. Major global changes included massive tectonic reorganization, a reduction in atmospheric
Late Quaternary Climate History of Northern Europe
Understanding the full range of natural climate variability is a fundamental basis for palaeoclimate reconstruction and for estimating the magnitude of the anthropogenic influence on global change.
THE TENDENCY OF CLIMATE CHANGE OVER THE PAST SEVERAL MILLIONS OF YEARS AND THE CURRENT INTERGLACIAL DURATION
The Earth's climate, from regional to global, varies on all time scales. Large-scale climate variations in the past can be related to changes in geological processes (plate tectonic) and orbital
Thresholds for Cenozoic bipolar glaciation
TLDR
It is found that Oi-1 is best explained by Antarctic glaciation alone, combined with deep-sea cooling of up to 4 °C and Antarctic ice that is less isotopically depleted than previously suggested, which implies that episodic northern-hemispheric ice sheets have been possible some 20 million years earlier than currently assumed and could explain some of the variability in Miocene sea-level records.
Quaternary oceans and climate change: lessons for the future?
There is much interest in ice-age studies in recent decades, in the context of global warming. The relevant findings are these: large regular changes in climate occurred within the last million
Evolution of global temperature over the past two million years
TLDR
A spatially weighted proxy reconstruction of global temperature over the past 2 million years estimated from a multi-proxy database of over 20,000 sea surface temperature point reconstructions suggests that stabilization at today’s greenhouse gas levels may already commit Earth to an eventual total warming of 5 degrees Celsius over the next few millennia as ice sheets, vegetation and atmospheric dust continue to respond to global warming.
Late Miocene decoupling of oceanic warmth and atmospheric carbon dioxide forcing
TLDR
It is proposed that a relatively deep global thermocline, reductions in low-latitude gradients in sea surface temperature, and cloud and water vapour feedbacks may help to explain the warmth of the late Miocene.
Movement of deep-sea coral populations on climatic timescales
During the past 40,000 years, global climate has moved into and out of a full glacial period, with the deglaciation marked by several millennial-scale rapid climate change events. Here we investigate

TLDR
Nonlinear responses of the carbon system may help to amplify relatively weak orbital insolation anomalies into more significant climatic perturbations through positive feedback effects, and transformed orbital-climatic cycles into long-wavelength features on time scales comparable to the residence times of carbon and nutrient elements in the ocean.
Orbitally paced climate oscillations across the Oligocene/Miocene boundary
The late Oligocene and early Miocene periods, some 21 to 27 million years ago, have generally been viewed as times of moderate global warmth and ice-free conditions. Yet several lines of evidence

Throughout the past three million years, variability in the oxygen-isotopic composition of the ocean, caused by changing ice-sheet mass on the continents, has been concentrated at the frequencies
Climate Response to Orbital Forcing Across the Oligocene-Miocene Boundary
TLDR
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.

TLDR
It is investigated the possibility that sudden reorganizations in ocean and/or atmosphere circulation during these abrupt transitions generated short-term positive feedbacks that briefly sustained these transient climatic states.
New chronology for the late Paleocene thermal maximum and its environmental implications
The late Paleocene thermal maximum (LPTM) is associated with a brief, but intense, interval of global warming and a massive perturbation of the global carbon cycle. We have developed a new orbital
Modeling 100,000-Year Climate Fluctuations in Pre-Pleistocene Time Series
TLDR
Results reported here from a modeling study suggest that such a response can occur over low-latitude land areas involved in monsoon fluctuations, and simulated fluctuations resemble those found in records of Triassic lake levels.
