We'll need to massively deploy technology that can suck CO2, trap it in something like silicate, and bury it deep underground. Or shift to a diet with less meat so land can be restored (this will suck some CO2 into biomass and soil). permalink fedilink source parent hideshow 1 child comment replies: [+] Cowbee@lemmy.ml 3 points 1 year ago (1 child) [removed by mod] permalink fedilink source parent hideshow 1 child comment replies: [–] emergencyfood@sh.itjust.works 2 points 1 year ago We actually have the tech - you just need to manufacture a CO2 scrubbing material and pass lots and lots of air through it. The hard part is the energy - you shouldn't be producing even more CO2 in the process. In other words, getting enough solar / nuclear power, and funding to actually build the thing. A cheaper alternative would be to pump nitrate and phosphate into some remote ocean, so as to cause an algal bloom. When the algae die, they sink to the bottom of the ocean, and take the carbon with them. But the local ecosystem will be fucked up in all sorts of ways. permalink fedilink source parent load more comments (-1 replies)
