Surgical anesthetic gases coming under fire for global warming potential – Only one problem: they haven’t been observed in the atmosphere

The press release below is from the University of Copenhagen Department of Chemistry. The anesthetic gases isofluran, desflurane and sevoflurane are coming under scrutiny for global warming potential. However, what isn’t stated in the press release is this important paragraph of the scientific paper :

There are no production numbers available in the literature
for the anaesthetic agents. The three compounds have not yet been observed in the free atmosphere, and current atmospheric levels are expected to be small (of the order of part per trillion/volume). At these concentrations, when viewed in isolation, their present contribution to the relative forcing of climate change is negligible in comparison with the current forcing of 1.7 Watts/sq meter due to CO2.

Webmaster's Commentary: 

More proof that any fool can get a grant for any study as long as the words "global warming" appear in the title. So, my grant proposal is a study on the effects of global warming on the size and thickness of bikinis, and the relationship between global warming and the popularity of going topless. Anyone care to fund this study? I'll take lots of pictures! Honest!
