TLDR
The world climate has changed from equitable global warmth during the Mesozoic to the present glacial climate which is characterized by strong differentiation between warm low latitudes and ice-capped polar regions as mentioned in this paper.About:

Journal ArticleDOI
Abrupt climate change and transient climates during the Paleogene: a marine perspective.
TL;DR: 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.

Miocene deepwater oceanography
Fay Woodruff,Samuel M. Savin +1 more
TL;DR: A global synthesis of Miocene benthic foraminiferal carbon and oxygen isotopic and faunal abundance data indicates that Miocene thermohaline circulation evolved through three regimes corresponding approximately to early, middle, and late Miocene times as mentioned in this paper.
Journal ArticleDOI
Cenozoic Glaciation in the Southern Hemisphere
TL;DR: For example, Cande et al. as mentioned in this paper argued that the fundamental cause of the formation of the Antarctic Ice Sheet and, eventually, to major glaciation in lower latitudes is generally held to have been the increasing thermal isolation of Antarctica as Australia and later South America, separated from it, allowing zonal oceanic circulation to develop.
Journal ArticleDOI
Pb and Nd isotopes in NE Atlantic Fe-Mn crusts: Proxies for trace metal paleosources and paleocean circulation
TL;DR: In this paper, high precision Pb isotopic data (2σ ≤ 100 ppm) together with Nd isotopes on depth profiles from two Fe-Mn crusts from the eastern Atlantic basin were reported.
Book ChapterDOI
Development of Cenozoic Abyssal Circulation South of the Greenland-Scotland Ridge
TL;DR: In this paper, the authors show that bottom-water sources for strongly circulating bottom water began in the late Eocene to early Oligocene, and that the gross nature of the circulation has not changed substantially since the middle Miocene.

Paleotemperature history of the Cenozoic and the initiation of Antarctic glaciation : Oxygen and carbon isotope analyses in DSDP Sites 277,279, and 281
TL;DR: An oxygen and carbon isotopic history based on analyses of benthonic and planktonic foraminifera in three overlapping subantarctic sections is presented for the last 55 m.y. as mentioned in this paper.
Journal ArticleDOI
Cenozoic evolution of Antarctic glaciation the Circum-Antarctic Ocean and their impact on global paleoceanography
TL;DR: Deep-sea drilling in the Antarctic region (Deep-Sea Drilling Project legs 28, 29, 35, and 36) has provided many new data about the development of circum-Antarctic circulation and closely related glacial evolution of Antarctica as discussed by the authors.
Journal ArticleDOI
Tertiary marine paleotemperatures
TL;DR: Oxygen isotopic compositions of the tests of planktonic foraminifera from several Deep Sea Drilling Project sites provide a general picture of low-latitude marine temperatures from Maastrichtian time to the present.
Journal ArticleDOI
The opening of Drake Passage
Peter F. Barker,J. Burrell +1 more
TL;DR: In this article, the authors used magnetic anomalies to deduce the history of the opening of Drake Passage, the deep-water channel between South America and West Antarctica, and concluded that the Antarctic Circumpolar current started at 23.5 ± 2.5 Ma, a time indistinguishable from the Oligocene-Miocene boundary.

Oxygen isotope and palaeomagnetic evidence for early Northern Hemisphere glaciation
TL;DR: Oxygen isotope and palaeomagnetic analysis of the lower half of LDGO piston core V28-179 shows that glacial-interglacial fluctuations have characterised Earth's climate for the past 3.2 Myr as mentioned in this paper.
