Atmospheric CO2 over the Past 66 Million Years from Marine Archives
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 …

[HTML][HTML] The Eocene–Oligocene transition: a review of marine and terrestrial proxy data, models and model–data comparisons
Abstract The Eocene–Oligocene transition (EOT) was a climate shift from a largely ice-free
greenhouse world to an icehouse climate, involving the first major glaciation of Antarctica …

Future climate forcing potentially without precedent in the last 420 million years
The evolution of Earth's climate on geological timescales is largely driven by variations in
