Sensitivity of temperature and precipitation to astronomical, ice, and CO2 forcing. a Mean annual temperature (MAT) and b mean annual precipitation (MAP) responses to precession and obliquity, ice, CO2, and coupled ice/CO2 forcing. Temperature and precipitation variances are spited into contributions for precession, obliquity, ice, CO2, and coupled ice and CO2 variation before the MPT (pre-MPT, gray) and after the MPT (post-MPT, blue), respectively. The combined ice/CO2 contribution is not estimated by simply adding up the individual impacts of ice and CO2 because their effects can partly cancel out each other
