Stop global warming using technology? (lemmy.world)

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

I think this is not the way.

It's like with dental care. The solution is not to don't care and think that someday technology will fix it. Instead you should brush regularly, don't eat much sugar and visit the dentist now and then. It's prevention.

We currently don't have any technology that will save us and time is running out. Why bet on a tech wonder that needs to be mass ready in no time?

There are a few YouTube videos out there where science communicators (one of them is Kyle Hill) do a few basic calculations on these projects and conclude that it’s impossible.

For example, the mirrors would need to be a swarm of satellites that are launched by hundreds of rockets every day for decades with no pauses.
