TL;DR: In this article, a compilation and synthesis of available planktonic foraminiferal δ18O and TEX86-SST proxy data for almost the entire Cretaceous Period is presented.

TL;DR: By comparing with observational datasets, it is shown that these models produce a good representation of many aspects of the climate system, including the land and sea surface temperatures, precipitation, ocean circulation, and vegetation, which motivates continued development and scientific use of the HadCM3B family of coupled climate models.

TL;DR: It is shown that, apart from a dry period in the middle Cretaceous, a monsoon system has existed in East Asia since at least the Early Cret Jurassic, with little influence from atmospheric CO2.

TL;DR: This article reported the discovery of the youngest well-preserved fossil palm leaves from Tibet, ca. 25.5 ± 0.5 million years, within the Lunpola Basin (32.033°N, 89.767°E) at a present elevation of 4655 m.

TL;DR: In this review, Earth system modeling, paleoaltimetry proxies and fossil finds contribute to a new synthetic view of the topographic evolution of Tibet, which suggests a flat-surfaced Tibet rose as a coherent entity.
