In an upcoming issue of the journal Geophysical Research Letters, NASA reports that “new research indicates a powerful greenhouse gas might be at least four times more prevalent than has been thought.” The level of nitrogen trifluoride — which “is thousands of times more effective at warming the Earth’s atmosphere than an equal mass of carbon dioxide” — has increased by a rate of 11 percent per year. Previously, “emissions of nitrogen trifluoride were thought to be so low the gas has not been considered a significant potential contributor to global warming.”These are all true facts, and makes NF3 sound very scary. But what they don't tell you is that current NF3 emissions contribute only 0.15% of the total global warming effect of current manmade CO2 emissions.
UPDATE: The AGU issued a correction overnight. The correct figure for NF3's contribution is 0.04%.
