We aren't at the point where we have zero waste. That's the problem because it doesn't matter if you have one kg or thousands of tons if it leaks it contaminates the environment all the same. Until we have fusion that's 100% safe and can get rid of all the waste it's not something we should be using.
Those are emissions, not atmospheric concentrations. And if you look at the real figures and not percentages you'd expect it to keep going up exponentially if it wasn't being used but it doesn't really, CO2 continues to make up just a fraction of atmospheric gasses.
Don't forget Three Mile island. Whenever nuclear safety is mentioned that one is always skipped. It should have been the death of nuclear at the time but the incident and its fallout was covered up as is a lot of nuclear fallout at the time it happens.
It hasn't been solved. It was left for future generations to solve on the assumption we'd have a means to actually dispose of it and the left over radiation by now but we are nowhere nearer today. Btw if we go the route of all nuclear our reserves would be depleted in a few decades in any case so it's not a viable long term solution.
You know, it really depends on your definition. ALL gasses absorb and release heat. It's what gives them volume. As they absorb heat they expand and this heat is transferred when they bump into one another or other gasses. So ALL gasses contribute to the greenhouse effect.
It has? Really it has?

Take another look especially at the parts just before man came on the scene.
Talk about morsels of truth, you know the moon does not have an atmosphere right? And while the sun does have a cycle it's not accurately repeated and there are times when it's hotter or colder. Why is it so inconceivable that we have this big fiery ball in the sky supplying ALL our energy that's driving our climate?
Who are also currently unable to return to the moon and have asked a South African billionaire to help them with their future space missions. Meh, sorry if I don't put much trust in them.
It's fallacious to compare the effect of huge quantities to miniscule ones. That's like saying if you die when I hit you at 100km/h with my car you'll still die if I hit you at 1km/h only slower.
Nope. You can only have models on things you actually understand. You can't understand things based on models. Adjusting models to fit your expected scenario is not science but BS. The only way to conduct real science on this would be to have a duplicate earth and see the effect between different conditions. Something the scale of the earth is simply too big to try and understand and put into models.
Has it occurred to you yet that the onus does not fall on anybody to prove it wrong (and there have been plenty) but on you to provide the burden of proof for your view? So you are aware but still make the statement and ask for counter proof. That is actually intellectual dishonesty.
