The atmospheric carbon situation is not good, and we (as a species) need to come up with actionable geo-engineering solutions. Here is one. Rainwater hits mountains and dissolves silicate minerals into cations that flow into rivers and then oceans. The oceans naturally uptake carbon from the atmosphere by reacting atmospheric carbon with cations in the water that come from those dissolved silicate minerals. This uptake de-acidifies the oceans and produces food for ocean life; for us to collect all the carbon produced in the USA last year, we would need to crush about 60km^3 of silicate rock (which is in abundance) and spread it along coastlines. To successful sequester enough carbon to save the ecosystem, this might one of the best options we have. This paper [1] does a good job of explaining what I've touched on here.
