A model/simulator to learn about changes in Earth’s climate caused by variations in the solar energy received by the planet over geological time scales and to understand the role of the orbital parameters (obliquity, precession, and eccentricity) in causing ice age cycles (Milankovitch cycles) on Earth.
Students can vary orbital parameters (eccentricity, obliquity, longitude of the perihelion) of Earth to observe the corresponding effect on the incoming solar radiation (insolation). They can also compare the global and seasonal distribution of insolation at two different points in time, and observe orbital data for particular times in the past and future (based on the paper by Laskar et al.).
