If you thought CO2 and methane were contenders for the most destructive greenhouse gases on the planet, then you will be shocked to learn that researchers have discovered another chemical that is considerably more damaging. Scientists at the University of Toronto say that a gas called perfluorotributylamine (PFTBA) is 7,000 times more potent than CO2 over a 100-year time period. Used in the electrical industry, each PFTBA molecule has a lifespan of 500 years and no known method of sequestration.
