I would explore a carbon capture megaproject before the one in the article. If we're going to spend that much, let's get closer to the root cause.

- WalterBright 8y ago> carbon capture megaproject Planting trees ought to do it.
- nine_k 8y agoYou also need to prevent the resulting trees from burning or rotting, to keep the carbon they captured intact. It was "easy" when tree trunks kept falling into ancient swamps for millennia. Right now it's not as feasible.
- WalterBright 8y agoLog them and build things with the wood.
- Something1234 8y agoWe're already kind of doing this. It just needs to be on a much larger scale maybe. I'm not sure of the complete process of how much CO2 is captured by a tree, so it might not make sense.
- WalterBright 8y agoCoal comes from dead trees.
- Something1234 8y agoYes. Old dead trees who's carbon has been removed for millions of years from the system. What happens when you dump a bunch more of anything into a system. Usually the system blows up.
- ozzy6009 8y agoTrees are still falling into swamps. The difference is that microbes can digest lignin/cellulose now.
- barry-cotter 8y agoNot unless you stop them rotting after they die. I’m sure there are actual experts with better proposals but turning them into charcoal/terra preta and using that as a soil growth promoter works as dies leaving wood in salt water until it ceases to be buoyant and then dumping it in the deep ocean.
- Reason077 8y ago”carbon capture megaproject” It’s hard to imagine any carbon capture technology that has a better ROI compared to technologies that reduce emissions. Or to put it another way, it’s much cheaper to not emit carbon in the first place than to try and recapture it.
