Flat screens a global warming risk?

The demand for plasma TVs could be adding to global warming, according to a recent Geophysical Research Letters article in which two US researchers noted that nitrogen trifluoride (N[F.sub.3])--used in the manufacture of flat-screen TVs--is also a potent greenhouse gas, with 17 000 times the global warming effect of carbon dioxide.

N[F.sub.3] is not covered by the Kyoto Protocol, so levels of this gas in the atmosphere are not currently measured.

CSIRO's Dr Paul Fraser says without measuring the quantity of N[F.sub.3] in the atmosphere, it is unclear what impact it will have on the climate.
