No mention of the loss of albedo. Harvesting and shipping rock flour from Greenland to sequester carbon in ag fields in Denmark sounds a little far-fetched in terms of how that would add up to a net reduction of CO2.
Some rocks absorb CO2 as they weather. Also, rocks provide minerals to fields which provide extra benefit.
Greenland with melted glaciers aren’t the only option. Olivine is rock that absorbs CO2 in seawater. We could grind and dump gigatons of it, and it is more accessible.
Every calculation I've seen regarding olivine comes out saying that the grinding and transport will release more carbon than the olivine will absorb, even accounting for technology improvements and green energy.
