As per The Guardian, researchers believe that, by accelerating the process of rock erosion, we could remove billions of tons of carbon from the atmosphere, as these emissions can be trapped in the rock powder produced by the grinding of heavy glaciers.
Additionally, they discovered that spreading the rock dust on Denmark's fields lead to better crop quality and more yields overall. In Greenland, the ice sheet's movement produces around one billion tons of rock powder every year, which then flows in the form of mud.
While researchers agree that we should stop pumping more carbon emissions into the atmosphere, capturing some of the CO2 that is already there is also critical to avoid the worst effects of climate change.
"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", says professor Minik Rosing at the University of Copenhagen.
According to the estimates of the research team, around 250kg of CO2 can be captured under one ton of rock powder and additionally, just by spreading it across all of Denmark's fields, we could get rid of 27 million tons of dangerous emissions.
