  • Earth orbit variations effect on climates and biomes during one major climate transition 2021-11-10 By comparing the results of simulations of the climate of the Eocene and Oligocene epochs, describing different configurations of the Earth's orbit, a study published in the journal Science Advances, shows the role of these orbital variations in the ancient climate variability and their influence on the vegetation cover.
