Reducing emissions may not have the effect you might think. First, once the CO2 is in the atmosphere, it stays there for a very long time (centuries to millennia). So stopping emissions would not stop the heat. Second, emissions also contain sulfer dioxide, which has a cooling effect through the formation of sulfate aerosols. These do not stay in the atmosphere for very long (only weeks). So in a scenario where these emissions stop, the immediate result would be a loss of that cooling effect and thus even more heat.
