Sounds like a fun "What If?" question (xkcd). But our planet (and with it, atmosphere) is hardly affected by humanity's activities adding heat directly. Instead it's GHGs that affect the inflow/outflow balance of heat from the sun. The heat from gasoline you burn is quickly dissipated. But the CO2 produced has an effect for many decades to come.
