Putting some kind of solar shield in L1 seems like a credible way to reduce energy input into the atmosphere. However, it creates a big “single point of failure”. And it’s difficult to believe we can build something of the size they propose (1.7 million sq km) in a timeframe that would make a significant difference to climate change without an Apollo or Manhattan-level of urgency.

Their plan is to make a lot of small devices rather than one large device. Just talking to the structure(s) is complex as there will be a huge noisy EM source right behind it.
