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:
USA CO² Scrubber german
Project Cypress english
Reading through these comments is depressing and my only hope is that I will be dead before the droughts lead to food shortages that effect me. I like eating, I like eating good food, I like having good food available when I want it. I don't like being hungry. I hope I'm dead before I have to deal with starvation. At least nuclear war would be quick.
Megaprojects are a pipe dream. We can't even deal with a lowball pandemic together as a nation. What hope do we have of coming together as a world? Let alone for something that isn't going to have immediate consequences slapping us in the face. We're a pathetic society that can't do anything good. All we do is consume. Mr. Smith was right, we're a virus.
We're heading for a post-apocalyptic sci-fi future, and all the horrible shit that goes along with it.
In a fucked up way, our only hope is if a mega power somehow dominates the world through some horrific war and consolidates power, while somehow avoiding nuclear war and then does a quick 180° straight into eco-fascism. That's the glorious future we have to look forward to. Life under a global authoritarian regime with severe austerity measures to deal with global warming. People will starve, people will be executed. The horrors of Stalinism will be our reality, and it is the only thing that can save us from ourselves.
I fucking hope I die, because I wasn't built for suffering.
My nation got pretty well behind the pandemic procedures and we had an vaccine like six months after the outbreak.
Oh, btw, I think a Mega-Project would be a much more feasable approach to the problem than Eco-Stalinism.
