In the end we need any solution that reduces emissions. Nuclear could be one of those, especially the thorium reactors that can burn some of the existing nuclear waste, are looking promising. Other than that, renewables are the way to go for sure. Still it won't solve other carbon sources, its just the energy sector. It cannot fix agriculture emissions, but maybe indirectly the building emissions, with new tech like electrically recycled concrete or green steel.
Will this happen in our current society... probably not, its just more profitable to fck the planet.
