During the Ordovician period, the concentration of carbon dioxide in Earth’s atmosphere was about eight times higher than today. It has been hard to explain why the climate cooled and why the Ordovician glaciations took place. A new study shows that the weathering of rock caused by early non-vascular plants had the potential to cause such a global cooling effect.
