Short summary

We analyzed climate model simulations to investigate what happens to the way the atmosphere moves heat around when the Sun is turned down to compensate for increased greenhouse gas concentrations. We found that the atmosphere transports less heat from the tropics to the poles, which helps us understand the patterns of warming or cooling at different latitudes. We also looked at the sources of uncertainty regarding changes in tropical rainfall patterns and found that clouds are the largest one.
