The tectonic history of Drake Passage and its possible impacts on global climate
This study provides an integrated review of plate tectonic models of the evolution of the Antarctica-Patagonia connection compared to geological records collected on land in Patagonia and Tierra delExpand
Asian monsoons in a late Eocene greenhouse world
Late Eocene climate records reveal marked monsoon-like patterns in rainfall and wind south and north of the Tibetan–Himalayan orogen, indicated by low oxygen isotope values with strong seasonality in gastropod shells and mammal teeth from Myanmar and by aeolian dust deposition in northwest China.

A ‘snowball Earth’ climate triggered by continental break-up through changes in runoff
Assessment of the palaeogeographic changes preceding the Sturtian glacial period and the long-term evolution of atmospheric carbon dioxide levels using the coupled climate–geochemical model GEOCLIM indicates that tectonic changes could have triggered a progressive transition from a ‘greenhouse’ to an ‘icehouse” climate during the Neoproterozoic era.

Modelling the primary control of paleogeography on Cretaceous climate
The low thermal gradients and clement winters characterizing climates of the Cretaceous period reveal that the climate system has modes of behaviour quite different from the present. Recent proxyExpand
Nutrients as the dominant control on the spread of anoxia and euxinia across the Cenomanian-Turonian oceanic anoxic event (OAE2): Model-data comparison
[1] The Cenomanian-Turonian oceanic anoxic event (OAE2) is characterized by large perturbations in the oxygen and sulfur cycles of the ocean, potentially resulting from changes in oxygen supply (viaExpand
Error analysis of CO2 and O2 estimates from the long-term geochemical model GEOCARBSULF
Long-term carbon and sulfur cycle models have helped shape our understanding of the Phanerozoic history of atmospheric CO2 and O2, but error analyses have been largely limited to testing only aExpand
The Sturtian ‘snowball’ glaciation: fire and ice
Abstract The Sturtian ‘snowball’ glaciation (730 Ma) is contemporary with the dislocation of the Rodinia supercontinent. This dislocation is heralded and accompanied by intense magmatic events,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
A GEOCLIM simulation of climatic and biogeochemical consequences of Pangea breakup
Large fluctuations in continental configuration occur throughout the Mesozoic. While it has long been recognized that paleogeography may potentially influence atmospheric CO2 via the continentalExpand
