Identifying the causal role of CO2 during the Ice Ages

Abstract:

We investigate past climate variability over the Ice Ages, where a simultaneous-equations system is developed to characterize land ice volume, temperature and atmospheric CO2 levels as non-linear functions of measures of the Earth's orbital path round the Sun. Although the orbital variables were first theorised as the fundamental causes of glacial variation by Croll in 1875 following Agassiz's conception of a 'Great Ice Age' in 1840, their minor variations were thought insufficient to drive s...
