Study documents reaction rates for three key greenhouse gases | R&D Mag The presence of these compounds in the atmosphere and their potential contributions to climate change were only recently recognized. Reaction with electronically-excited oxygen atoms is the only known pathway by which these compounds are destroyed at atmospheric altitudes below the ionosphere. Though present at relatively low levels today, studies show that their concentrations are increasingwith atmospheric levels of NF3 growing at more than 10 percent per year. These chemicals are relatively inert, which makes them useful for specific applications, Wine said. But because of their chemical inertness, they tend to have long lifetimes in the atmosphere and are available to trap radiation for a long time. That contributes to their high global warming potential. ------------------------------------- Doncha just hate Democrats with all that science and stuff? Chemical reaction, bonding, greenhouse gasses? Republicans know all about science. Ask them.
