A long-known but little-tested means of permanently storing carbon dioxide ( co2 ) underground , mineral carbonation , is now the subject of study in iceland and oman .
The good news is that mineral carbonation promises to lock away co2 a powerful greenhouse gas in a much more stable form than simply pumping it into an underground geologic formation .
Dr. pelchat added a few more interesting facts : women tend to prefer less carbonation in their wines and are usually more sensitive to bitter flavors than men .
