  journal={Earth-Science Reviews},
Abstract This study provides a comprehensive and quantitative estimate of how global temperatures have changed during the last 540 million years. It combines paleotemperature measurements determined from oxygen isotopes with broader insights obtained from the changing distribution of lithologic indicators of climate, such as coals, evaporites, calcretes, reefs, and bauxite deposits. The waxing and waning of the Earth’s great polar icecaps have been mapped using the past distribution of tillites… Expand
Paleotemperature record of the Middle Devonian Kačák Episode
New δ18Oapatite data from the Carnic Alps and the Prague Synform are provided, which suggest that SSTs of the southern hemisphere low latitudes were higher than previously assumed for this time interval. Expand
New paleogeographic and degassing parameters for long-term carbon cycle models
Abstract Long-term carbon cycle models are critical for understanding the levels and underlying controls of atmospheric CO2 over geological time-scales. We have refined the implementation of twoExpand
Spatial continuous integration of Phanerozoic global biogeochemistry and climate
Abstract It is important to understand how Earth's surface conditions have changed over geological timescales and what has driven these changes. Much of this understanding comes from combiningExpand

The Lower Cretaceous Dalazi Formation in the Yanji Basin, eastern Jilin Province is of particular interest because it contains key fresh water fossil taxa, oil and gas resources, a potentialExpand
Karst bauxite formation during Miocene Climatic Optimum (central Dalmatia, Croatia): mineralogical, compositional and geochronological perspectives
The Miocene Climatic Optimum (MCO) represents a global warm period (approximately 17–14.7 Ma) interrupting a long-term period of Cenozoic cooling. To elucidate if bauxitization took place inExpand
Earth history events shaped the evolution of uneven biodiversity across tropical moist forests
The model indicates that high biodiversity in Neotropical and Indomalayan moist forests is driven by complex macroevolutionary dynamics associated with mountain uplift, and lower diversity in Afrotropical forests is associated with lower speciation rates and higher extinction rates driven by sustained aridification over the Cenozoic.

Abrupt climate changes and the astronomical theory
Abstract. Abrupt climate changes constitute a relatively new field of research, which addresses variations occurring in a relatively short time interval of tens to a hundred years. Such time scalesExpand
Multidisciplinary approach as a key for paleoenvironmental interpretation in a Weichselia-dominant interval from the late Aptian Codó Formation (Parnaíba Basin, Brazil)
Abstract The presence of the fern Weichselia in a restricted sedimentary interval of a drilling core in the Parnaiba Basin (Brazil) was used as a lead for paleoenvironmental interpretationExpand

Abstract Increasing evidence shows that the recovery of marine ecosystems after the Permian/Triassic mass extinction (PTME) was coupled with environmental amelioration. Recently, abundant insects andExpand
Middle Jurassic–Lower Cretaceous glendonites from the eastern Barents Shelf as a tool for paleoenvironmental and paleoclimatic reconstructions
Abstract Glendonites are carbonate pseudomorphs after ikaite which use as indicators of near-freezing temperatures. We describe the first glendonites of Middle–Late Jurassic to Early Cretaceous ageExpand


Temperatures and oxygen isotopic composition of Phanerozoic oceans
Abstract The temperature of ancient oceans is an important constraint for understanding the climate history of our planet. The classical oxygen isotope paleothermometry on fossil shells, while veryExpand
Temperature evolution and the oxygen isotope composition of Phanerozoic oceans from carbonate clumped isotope thermometry
Abstract Surface temperature is among the most important parameters describing planetary climate and habitability, and yet there remains considerable debate about the temperature evolution of theExpand
Climate and geology – a Phanerozoic perspective
The Phanerozoic is comprised of over 540 million years and, with its defining accompaniment of abundant complex life, provides us with a unique perspective on the extremes of climate change.Expand
Modeling the early Paleozoic long-term climatic trend
The early Paleozoic climate has been described as warm and equable. However, recent data based on conodont oxygen isotopic composition reveal a large, long, cooling trend through the Ordovician,Expand
Paleoclimates, ocean depth, and the oxygen isotopic composition of seawater
A recurrent interpretation of ancient climate based on the oxygen isotopic composition of marine carbonates and cherts suggests that Earth's climate was substantially warmer in the distant past andExpand
Paleoclimate of the Kimmeridgian/Tithonian (Late Jurassic) world: I. Results using a general circulation model
Abstract The Kimmeridgian/Tithonian (154.7−145.6 Ma) (middle and late Late Jurassic) was a time of expanded continental rifting, increased sea-floor spreading, and a relatively high eustatic seaExpand
An early Cambrian greenhouse climate
The results support an early Cambrian greenhouse climate comparable to those of the late Mesozoic and early Cenozoic, offering a framework for exploring the interplay between biotic and environmental controls on Cambrian animal diversification. Expand
Very large release of mostly volcanic carbon during the Paleocene-Eocene Thermal Maximum
Boron isotope data are presented that show that the ocean surface pH was persistently low during the PETM, and enhanced burial of organic matter seems to have been important in eventually sequestering the released carbon and accelerating the recovery of the Earth system. Expand

This study explores the sensitivity of the simulated pre-PETM and PETM periods to change in cloud condensation nuclei (CCN) and microphysical properties of liquid water clouds and indicates that past differences in cloud properties may be an important factor in accurately simulating past warm climates.
