Throughout Earth's history, CO2 is thought to have exerted a fundamental control on
environmental change. Here we review and revise CO2 reconstructions from boron isotopes …

Because of human action, the Earth has entered an era where profound changes in the
global environment are creating novel conditions that will be discernable far into the future …

2 Chapter 2 assesses observed large-scale changes in climate system drivers, key climate
indicators and 3 principal modes of variability. Chapter 3 considers model performance and …

The cause of the end-Cretaceous mass extinction is vigorously debated, owing to the
occurrence of a very large bolide impact and flood basalt volcanism near the boundary …

Event stratigraphy is used to help characterise the Anthropocene as a chronostratigraphic
concept, based on analogous deep-time events, for which we provide a novel …

The Cretaceous/Paleogene mass extinction, 66 Ma, included the demise of non-avian
dinosaurs. Intense debate has focused on the relative roles of Deccan volcanism and the …

The Chicxulub impact is thought to have triggered a global winter at the Cretaceous-
Palaeogene (K-Pg) boundary 66 million years ago. Yet the climatic consequences of the …

Abstract The Permian/Triassic boundary approximately 251.9 million years ago marked the
most severe environmental crisis identified in the geological record, which dictated the …

The geological record encodes the relationship between climate and atmospheric carbon
dioxide (CO2) over long and short timescales, as well as potential drivers of evolutionary …

Water plays a critical role in erosion and sediment transport and this relationship is most
evident in the hyperarid Atacama Desert of Northern Chile, a region characterized by …
