I don’t think human psychology will allow a united approach to global warming. Too man people are too stupid, to egoistic or just in such a tight spot they can not afford being “climate-friendly”.
So I wonder if there are Mega-Projects available to stop global warming?
Some coming to mind:
Reflector mirror at Lagrange1 between Sun and Earth - even a 1.000.000km² mirror from ultrathin film would weigh 1000 tonnes at most.
Giant Air Scrubers and I mean giant. They would dwarf the pyramids and remove pullutants and CO² from the athmosphere.
In addition I think a originator principle should become common: Any nation not really trying to act clean should simply be burdened with massive tariff measures. Using modern technology it shouldn’t be too hard to find nations who polute the ocean unnececerrally.
Edit, it became reality:
Pie in the sky mega projects won’t save us.
Honestly even humouring the idea is frankly dangerous, the only thing it will do is let shitheels kick back and do nothing because it’ll totally be taken care of by X.
Reminds me of all the Liberals (right wingers) in my country pushing carbon capture technology as the solution and undoing all the work done by the Greens.
Yeah, I’m usually a quite tech positive person. But things like carbon capture, hydrogen and so on are so often pushed as the solution.
But they simply are not viable or economic for anything but niche cases.
