Scientists have discovered that rock "powder" from Greenland could help to remove considerable amounts of CO2 from the air, which could potentially help countries to reach their climate targets. Not only that, but it could also help farmers to increase their crop yields. It's safe to say that both of these benefits are quite significant, and could help both the planet and humans. However, how exactly does it work?
As it turns out, the powder is created through grinding under glaciers in Greenland. From here, it can then be used to take in CO2 via natural chemical reactions which take place. Prof Minik Rosing from the University of Copenhagen stated the following: "Above all this is a scalable solution. Rock flour has been piling up in Greenland for the past 8,000 years or so. The whole Earth’s agricultural areas could be covered with this, if you wished.”
To give an example of just how scalable using the substance would be, researchers found that if it was spread across all the agricultural land in Denmark, over 27 million tons of CO2 would be captured, which is quite a significant amount.
In addition to advancements such as these, scientists and researchers from across the globe are also developing solutions such as CO2 fighting moss on buildings and CO2 capturing devices on a large scale. Combined, all of these solutions could help to contribute toward lowering global CO2 emissions, if implemented correctly.
