Replacing fossil fuels with nuclear helps prevent further CO2 emission but doesn’t mitigate past emissions.

What’s already been released is enough to have already changed the climate and will continue warming the planet as long as it’s in the atmosphere.

Planting trees helps remove CO2 from the atmosphere that we’ve already released.

We should be both planting trees (to reverse past emissions) and changing our energy sources (to minimize future emissions).
