By now most people will agree that solutions are needed to the solve climate change. Solutions exist but up to now trying to lock the carbon in the atmosphere safely and for long periods of time were not successful.
But now, scientists in Iceland have been able to turn the gas into stone and so lock it away in a permanent way. The gas is dissolved with water and the mixture is pumped into certain rocks. The reaction of the mixture with the rocks means that the mixture forms a mineral called calcite.
For the process to work some stones are better than others. Volcanic rocks called basalts are the best for this process as they are rich in calcium, magnesium and iron reacting with CO2 in an ideal way.
The great advantage of this process is that 95% of the carbon dioxide is converted into calcite and this happens very quickly, in less than two years. As the conversion is rapid so will be the monitoring of the process.
The negative about this new technique is that the scale of the projects would have to be larger than the ones being experimented right now, and a lot of water would be needed as well as the right kind of rock.
The best solution according to scientists would be to use the ocean floors and the margins of the continents to safely store the CO2. It seems as well that using sea water would also work well with the process.
Of course more testing still has to be done, nevertheless if this technique works perhaps the consequences of climate change could be mitigated to a large degree, giving us a chance to better be prepared for the unpredictable consequences of such a major upheaval.
