This also unfortunately makes a case against nuclear. For instance the worst coal burning country in Europe is Poland, which 5 years ago decided to build nuclear plants. They are set to break ground in a couple years and the first plant will be finished 2033 or so. The last ones 2040. And this all if it goes according to plan, which it won't. And even then they will be left with a significant amount of coal burning plants in the system. So at least 15 years of effort to get one plant online during which time the country will continue to pump CO2 to the tune of 70% coal in their electricity mix. CO2 that will, as you say, continue to bake the earth. Nuclear is a terrible choice for decarbonization.
