“We need to deal with rising carbon emissions. Scientists have turned carbon dioxide into stone in a matter of months by pumping it deep underground, offering a revolutionary new way of storing the greenhouse gas to tackle climate change. Carbon dioxide is a key factor in global warming, and experts have long called for innovative “carbon capture and storage” (CCS) solutions. A porous, blackish rock, basalt is rich in calcium, iron and magnesium, minerals researchers said are needed to solidify carbon for storage. The pioneering experiment in Iceland mixed CO2 emissions with water and pumped it hundreds of meters (feet) underground into volcanic basalt rock -- where it rapidly turned into a solid.
