    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 increasing—with 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.

    All too many scientists keep repeating the mantra of staying below 450 ppm of CO2. They seem to think that this is a safe limit.

    Between the increase of CH4 to 1.7 ppm, and the industrial gases like those in the article, as well as many others not mentioned, we have already exceeded that limit in equivelant warming capability.

    We now can measure the amount that ocean clathrates are at present contributing to the methane levels, and that is not good.

    Now if only dumb old Earth would understanding the science and start warming...sigh.

    Now if Frank would only come down out of his Hollow Moon, and look around, he could see the warming.

    Said it before and I'll say it again: there's far more evidence that the Moon is an artificial, hollow body than there is for Manmade Global Warming, and I have the science to prove it.
