Abstract
The effect of CO2 concentrations on 13C/12C ratios in C3 plants, comprising most of Earth’s vegetation, is currently debated. Here, using ice core records and plant and animal fossils, Hare et al. find evidence for a pCO2 effect, with implications for palaeoecology and plant responses to climate change.
