Changes in latent heat flux, low-level cloudiness, and net solar flux at surface in response to CO2-radiative forcing, CO2-physiological forcing, and combined CO2-radiative and physiological forcing. They are averaged annual mean changes in response to a doubling of atmospheric CO2 calculated from the last 70-yr results of 100-yr simulations. Hatched areas are regions where changes are not statistically significant at the 5% level using the Student t-test.
