If every government had subsidized and pushed forward a transition to ~100% nuclear power back in the 70s it would have effectively solved climate change. Electricity, industry and heat production account for >50% of CO2 production.

Then there's all the other effects of not having a high demand for hydrocarbons including less Middle East entanglement, less mining and drilling, more abundant and cheaper oil for uses other than burning it, etc.
