Among the large set of people who think we should take steps to reduce anthropogenic global warming there are at least two subsets who seem to oppose nuclear power. One is sort of pseudo-religious and believes that any disruption of the natural environment is a "sin" against Mother Nature. The other claims that nuclear power is too expensive and that we can solve the base load power problem more cheaply with battery storage, despite the lack of evidence that we'll be able to scale it up fast enough in the time available. And I have nothing against building more battery storage where it makes sense, but I don't think that's going to be sufficient by itself.
