Comparing waste from coal, oil and natural gas to nuclear waste is a difficult discussion to have. Climate change is not caused by nuclear waste. We can hit any temperature goal we want regardless of how much nuclear waste is generated.

My own personal view is that the threat from global warming is worse than the threat of nuclear waste buildup. This is why I usually comment that we should ban burning fossil fuels for power generation and then first afterward start the discussion on how we want to create the energy grid of the future. Nuclear waste is a very relevant topic once we got to the point that we agree that burning fossil fuels has to stop and we decided which day the fossil fueled power plants must shut down.
