No. The car will still be running even if we fully stop right now. There is an excess of carbon in the atmosphere, there are feedback loops that are emitting carbon due to the already existing warming, you don't shutdown the greenhouse effect with just a halt or slowdown of emissions because what is already there will keep doing its job.

What you can do switching to nuclear (in some industries, at least) is to not increase as much as previous years what we add to the problem.

It's not stopping, nor slowing down or keeping the current speed, but just accelerating a bit less than before.

Massive carbon capture is needed (orders above the gigantic amount that is added each year, because you need to take out the carbon emitted in the previous years too, and there is the feedback loops playing too), along with bringing new emissions sharply down. And all of that at least for many years after reaching below preindustrial carbon levels (global temperature should drop enough to turn off the positive feedback loops).
