Bandersnatch said:We are not at risk of CO2 depletion, nor is human activity needed to maintain its natural levels, so what was this question even asked for? Was it an argument to the effect that CO2 is necessary for life, therefore we need more of it - in the same way as people affected by flooding need more life-giving water?.
That is a great analogy, almost. Thank you! Its important that the natural cycles are capable of subsorbing our contributions to them. However, too much CO2 will not flood and kill a field of crops. It won't overwhelm a dam (causing it to break and/or allow flooding). It was not an argument to say that we need more CO2. It was pointing out that we are closer to having CO2 deficiency than we are to having any negative effects of CO2 surplus that we know of with as much certainty as the negative effects of CO2 deficiency.
Bandersnatch said:Water vapour is a strong greenhouse gas, but it's irrelevant because, unlike CO2, it's also a condensing gas. If you put too much of it in the atmosphere, clouds form, followed by precipitation. Its concentration self-regulates.
Sounds like quite a life-giving event. More clouds and more rain water? I'm sure that could not possibly ever be anything other than benign, right? Should we go ahead and assume that the risk is negligible when we expand the scale of nuclear energy?
