How to remove carbon dioxide from the atmosphere with olivine
Back in 2012, I read this article by John Rennie at ZDNet which literally changed my life. It describes scientific research that proves (in laboratory research) that mining olivine (a green mineral that is abundant on Earth), crushing it and distributing it in shallow tidal basins in the oceans where there is significant wave action will have two effects: pull carbon dioxide right out of the air, and also de-acidify the oceans at the same time. The authors of the paper claim that if we were to do this at scale, humans would be able to remove the amount of C02 produced in a year. In other words, it would be like humans just didn't produce any carbon dioxide that year. If that were to happen, the C02 level would stop rising, and the oceans would stop becoming more acidic. That, combined with lower carbon dioxide emissions in general, could halt our current climate change trend. This "enhanced weathering" technique doesn't require olivine ...
