And yes Prince George and COP426 in 2051 will be saying exactly the same things.
Or maybe it will be: “How did we know we’d need to install a giant sunshade at L1 to avoid disaster when we closed down commercial space flight in the 2020s?”
I'm really not a fan of geo-engineering to solve global warming. Except for that very idea, actually.
The reason ?
a) it doesn't screw Earth proper, as would "iron in the oceans" or "sulfur in the sky" schemes.
b) if it eventually start screwing Earth by dimming the Sun (for some unexpected reason), at worse let the "sunshade" scatter away under Sun-Earth-Moon gravitational influences and solar pressure.
That's the one and only geo-engineering scheme against global warming I could eventually support.
Provided of course it doesn't become a pretext for a new "carbon porn fest" and "CO2 orgy".
"Hey, global warming is stopped, let's bring back coal and oil by the gigatons !"
In passing, it wouldn't mitigate ocean acidification since that scheme attacks global warming through the Solar flux - rather than CO2 emissions.
There is also a very real risk of destroying the lunar environement by seizing billions of tons of regolith to provide the starshade basic materials.
I wonder if somebody is calculating a "lunar dust shade against global warming" via BFR-Starship flights.
Imagine the headlines
"SpaceX stops global warming and save the day". For good or worse, Musk would become the all time hero of our era. This would be like "Tesla solved the electric car issues" except cubed.
