Stopping emissions (which isn't even in the Overton window) means CO2 concentration will slowly reduce. "Between 65% and 80% of CO2 released into the air dissolves into the ocean over a period of 20–200 years. The rest is removed by slower processes that take up to several hundreds of thousands of years, including chemical weathering and rock formation. This means that once in the atmosphere, carbon dioxide can continue to affect climate for thousands of years." During the time of elevated CO2 levels, the temperature continues to rise.
