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 …

The alkenone–p CO2 methodology has been used to reconstruct the partial pressure of
ancient atmospheric carbon dioxide (p CO2) for the past 45 million years of Earth's history …

The early Eocene (56 to 48 million years ago) is inferred to have been the most recent time
that Earth's atmospheric CO 2 concentrations exceeded 1000 ppm. Global mean …

The Pliocene period is the most recent time when the Earth was globally significantly (∼ 3°
C) warmer than today. However, the existing pCO2 data for the Pliocene are sparse and …

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 …

Earth's modern climate, characterized by polar ice sheets and large equator-to-pole
temperature gradients, is rooted in environmental changes that promoted Antarctic …

Marine algae are instrumental in carbon cycling and atmospheric carbon dioxide (CO2)
regulation. One group, coccolithophores, uses carbon to photosynthesize and to calcify …

We present a summary of biomass data for 11 plankton functional types (PFTs) plus
phytoplankton pigment data, compiled as part of the MARine Ecosystem biomass DATa …

Calcification and biomass production by planktonic marine organisms influences the global
carbon cycle and fuels marine ecosystems. The major calcifying plankton group …
