In that case, neither is fusion, which is essentially free energy forever.

It opens up the avenue for many more warming and CO2 mitigation techniques that are a reality today (e.g. desalination on a global scale and massive reforestation of Africa and the Amazon)

As well as the ability to stop burning fossil fuels much quicker than transitioning to solar/wind.

It's interesting how you think it's possible to do massive reforestation in Brazil and Africa. Think about massive reforestation of Europe or the eastern USA and I think you'll see the fundamental problem with it. That land has already been put to other use (mostly agricultural use) and cannot simply be reforested. The government would have to repurchase the land from each individual land owner to do that which is not at all practical.

To be fair, France currently has more forests than it did a century ago.
