I don't know why we aren't going full bore on developing a sun shade that we have some control over so regardless of the cause we can just regulate the temperature of the planet. You can say it is risky to engage in terraforming projects like that but we have already been engaging in terraforming for hundreds of years now with no plan at all. Also humans are pretty good at uniting around one singular huge project, but pretty bad at the millions of small projects that are required to fix this problem the correct way.

Even at projected SpaceX lift prices of $1000/lb access to space is still prohibitively expensive. The Earth is big and a big mirror would be needed: millions of tonnes size range. Not only that but it would have to be delivered to the L1 Lagrange point, SpaceX prices are for lift to LEO only. https://en.wikipedia.org/wiki/Space_sunshade https://en.wikipedia.org/wiki/Space_sunshade Conceptually it would work fine, economics are a problem.
