Capturing carbon dioxide from the atmosphere and storing it, also known as carbon sequestration, is one of many methods to mitigate climate change. Carbon dioxide is usually stored in underground geologic formations or biologic forms like forests, soils, or oceans through various methods. In new research, scientists found that applying basalt dust in croplands can effectively sequester atmospheric carbon dioxide at the gigaton scale. […]
