These include changes in the radiation from the Sun, changes in the tilt of the Earth, changes in Earth's orbit, changes in greenhouse gas concentrations in the atmosphere, shifts in the location of land on earth through plate tectonics, and changes in ocean circulation.
This section discusses the causes of Atmospheric and Oceanic circulation and the roles that Atmospheric and Oceanic circulation have in regulating Earth's climate and Energy balance.
