Weathering is exactly how the earth brought itself back into equilibrium over millions of years after the mass extinction events. We just have to advance that process dramatically, and specifically target beaches and critical places in the ocean where ocean acidification would devastate ecosystems.
Edit: Also this is an affordable plan. It costs about $12 per metric ton of carbon removed compared to other carbon sequestration technologies which usually cost $100+/ton.
- fouc 7y agoDon't need a billionaire, just need a kickstarter or indiegogo to make that happen.
- halfjoking 7y agoLuckily someone else is already doing that and I've already donated to it: https://projectvesta.org/ https://projectvesta.org/ If we want to offset a huge chunk of human emissions we still need billionaire or government backing.
- carapace 7y agoOlivine weathering seems very hopeful!
