Numerical experiments on paleoclimate modeling
Abstract The influence of climatic parameters (values of CO 2 concentration in the atmosphere, solar constant), the configuration of continents, as well as the distribution of the depths of the World Ocean, characteristic of the time periods under consideration, on the climate is investigated.
