I’ll bet when you think of all the studies being done on CO2 and Global Warming, you probably figure a lot of it has to do with the atmosphere or the ocean or plants of some kind—since that’s what it seems to affect the most. However, scientists have recently developed a method for finding and tracking CO2 underground. Why underground? Well, consider that a lot of emissions come from power plants—coal plants and the like—so, scientists started investigating underground caverns, fissures and coal beds to find places where those emissions can be stored; thus reducing the amount of greenhouse gases in the atmosphere. So, how do they find and track the carbon? They used colorless, non-toxic liquids called perfluorocarbon tracers. These tracers were used to fingerprint CO2 that was injected into a coal seam in New Mexico. By tracking the tracers, they were able to follow the movement of the CO2.
