Toronot researchers estimated PFTBA remains in the atmosphere for about 500 years, and unlike carbon dioxide, that is taken up by forests and oceans, there are no known way for the earth to absorb it.
Hong said the discovery of PFTBA and its warming potential raises questions about the climate impacts of other chemicals used in industrial processes.
PFTBA is used in electrical equipment, such as transistors and capacitors though researchers said it was unclear how widespread its use was today.
