[liff] Upside/Downside: Canned "Air"

851 Those cans of "compressed air" (which, as it turns out, ain't really air) that you use to clean out your computer keyboard and dust off your printed-circuit cards...
  • Upside: Contains 1,1,1,2-Tetraflouroethane, street name HFC-134a, which, though being derived from flourocarbons, does not harm the ozone layer.
  • Downside: One 10-ounce can does, however, have thousands of times the global-warming punch of simple ol' CO2.
Eric DePlace at the Sightline Institute confronts the ugly truth here, with a follow up here.

This has been another edition of Upside/Downside.
