TL;DR: 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.

TL;DR: In this paper, the authors present high-resolution (1-9 kyr) astronomically-tuned climate proxy records in two complete sedimentary successions from the northwestern and southeastern Pacific (ODP Sites 1146 and 1237), which shed new light on the middle Miocene carbon-isotope excursion and associated climatic transition over the interval 17.1-12.7 Ma.

TL;DR: In this article, high-resolution 3D ocean modeling and paleoceanographic reconstructions were used to understand the origin and causal links behind global climate changes, with ice sheets around the North Atlantic and its thermohaline circulation as prime candidates for a potential trigger mechanism.

TL;DR: In this article, high-resolution geochemical records from a depth transect through the Cenomanian/Turonian (C/T) Tarfaya Basin (northwest African Shelf) reveal high-amplitude fluctuations in accumulation rates of organic carbon (OC), redox-sensitive and sulphide-forming trace metals, and biomarkers indicative of photic zone euxinia.

TL;DR: In this article, high-resolution (1-3 k.y.) benthic stable isotope data with X-ray fluorescence scanner-derived biogenic silica and carbonate accumulation estimates in an exceptionally well preserved sedimentary archive, recovered at Integrated Ocean Drilling Program Site U1338, was used to reconstruct eastern equatorial Pacific productivity variations and investigate temporal links between high and low-latitude climate change over the interval 16-13 Ma.
