We can and do control nuclear fission, and should not automatically exclude that source of "renewable energy" (literally, new energy created out of mass). The objections raised by Andy and others seem more political than scientific. It would not, technologically, be impossible to build new reactors within ten years. Indeed if it became a world priority I believe it could be done in five years.
I really appreciate your insights - and have from the beginning of this forum. I cannot, however, agree with your 'renewable energy' label as there's nothing renewable about extracting finite radioactive materials from the planet and tapping the heat. We're not creating energy anyway as that would violate the laws of thermodynamics.
I've worked to clearly and accurately state my objections to using new nuclear generation to solve our carbon problem and have cited sources, and my position is absolutely not political. If we assume that we're going to build enough current tech light water reactors to replace fossil fuel use and thus satisfy WetEV's obsession with the Keeling curve over all else
then the science is clear - we do not have enough skilled people to build the plants we need in the time we need them, and we do not have enough fuel available on the planet in 'carbon neutral' quantities to refuel those reactors for the period of time we need to lock our climate where it will be on the day the reactors are finished. We're already tapping lower quality, more energy intensive uranium sources just as we're tapping lower-quality and more energy intensive fossil fuel supplies. All of that completely ignores politics, planning, environmental impact statements, and diminishing water resource availability on a warming planet.
Pro-nuclear folks will say (and have in this thread) that we have enough uranium in sea water to power the planet's fission reactors - all we have to do is sift it out - one molecule at a time. It is also true that atoms and molecules of metal fall off our metallic eating utensils and end up in our carpeting and in the water pumped from the dishwasher - but nobody in their right mind suggests that we should start super-vacuuming the house when one of our teaspoons goes missing. Again - the laws of thermodynamics at work. Entropy is...

Of course it should be a world priority to stop producing energy from coal. But that is just the dirtiest form of hydrocarbon. It also needs to be a world priority to stop producing energy from oil and natural gas. They are all destroying the earth. I don't buy the argument that we should try to slow pumping of carbon into the atmosphere by pulling ever more carbon out of its safe storage underground.

Some Americans are obsessed with the trillions of dollars of debt we are passing to future generations. That's not good, I agree, but it pales to insignificance compared with the quadrillions of dollars our children and grandchildren are going to be forced to pay to get all that excess carbon out of the atmosphere and ocean and back safely underground again. Forced, because if they don't do it climate change will become an existential threat to the survival of the species.

The people fixated on our national debt are not stopping to realize that our entire monetary system - and our entire system of economics - is based on debt. It's not just based on debt, it's based on the absolute NEED to continue to increase that debt. If We the People were to write a huge check and 'pay off our debt for the benefit of our children' our entire economy would crash. Good luck finding little Freddy a job after THAT happens. Good luck building a nuclear power plant - or anything else - as well.

Ray, since we cannot take the planet's (or country's or state's or even county's) power grid off-line for an overnight upgrade from fossil fuel generation to wind, water, and solar generation, the best we can do is to continue to measure emissions and keep working to make those numbers go to zero as quickly as we can. As far as I can tell, that means that we must get comfortable with the fossil fuel plants that keep running today as we count down to the day that they aren't. Not great, but I think it's best we can do.
