Many papers discus the controlling mechanisms that may have forced major climate change, such as geographical and oceanographic changes during the Late Ordovician or changing ocean gateways in the Cenozoic, while others discuss biological and chemical proxies that can be used to track ancient climate change, such as the use of Ca/Mg ratio of foraminifer tests or alkenones from surface- dwelling marine-algae.
