Rocks Around the Clock?

German scientists have suggested that much of the surplus carbon dioxide being released into the atmosphere could be removed by rock action ( They have found that crushing basalt and dunite rocks (the latter rock type has the greater impact)  causes them to react with carbon dioxide, forming bicarbonate ions that might well be washed away by rain water and eventually converted (with the help of organisms) into limestone. This would reduce the global warming effects of the 'greenhouse' gas. The only problem is that it would require activity on a par with coal-mining in earlier years.
