Short summary

We have discovered a new compound in the atmosphere, octafluorooxolane (c-C₄F₈O), from measurements in archived air samples. From our laboratory studies, we find that c-C₄F₈O is a very powerful greenhouse gas thereby contributing to global warming, and that it has a very long atmospheric lifetime of more than 3500 years. Based on our measurements we could reconstruct its atmospheric evolution over more than 4 decades. Based on this, we could estimate the global emissions of c-C₄F₈O.
