Editing Halothane (section)

===Greenhouse gas===
Owing to the presence of covalently bonded fluorine, halothane absorbs in the [[atmospheric window]] and is therefore a [[greenhouse gas]]. However, it is much less potent than most other [[chlorofluorocarbons]] and [[bromofluorocarbons]] due to its short atmospheric lifetime, estimated at only one year vis-à-vis over 100 years for many [[perfluorocarbons]].<ref name="potential">{{cite journal| vauthors = Hodnebrog Ø, Etminan M, Fuglestvedt JS, Marston G, Myhre G, Nielsen CJ, Shine KP, Wallington TJ |title=Global warming potentials and radiative efficiencies of halocarbons and related compounds: A comprehensive review |journal=Reviews of Geophysics |date=24 April 2013 |volume=51 |issue=2 |pages=300–378| doi = 10.1002/rog.20013 | bibcode = 2013RvGeo..51..300H | url = https://centaur.reading.ac.uk/31338/1/ReviewGWP_2nd_rev_v2.pdf }}</ref> Despite its short lifespan, halothane still has a [[global warming potential]] 50 times that of carbon dioxide, although this is over 100 times smaller than the most abundant fluorinated gases, and about 800 times smaller than the GWP of [[sulfur hexafluoride]] over 500 years.<ref name="Updated">{{cite journal | vauthors = Hodnebrog Ø, Aamaas B, Fuglestvedt JS, Marston G, Myhre G, Nielsen CJ, Sandstad M, Shine KP, Wallington TJ | title = Updated Global Warming Potentials and Radiative Efficiencies of Halocarbons and Other Weak Atmospheric Absorbers | journal = Reviews of Geophysics | volume = 58 | issue = 3 | pages = e2019RG000691 | date = September 2020 | doi = 10.1029/2019RG000691 | pmid = 33015672 | pmc = 7518032 | bibcode = 2020RvGeo..5800691H }}</ref> Halothane is believed to make a negligible contribution to [[global warming]].<ref name="potential"/>
