Scientists in Canada on Tuesday announced the discovery of a greenhouse gas with unprecedented potential to warm the Earth, and said the chemical has been lurking in the atmosphere for decades.
The substance perfluorotributylamine (PFTBA) is the most radiatively efficient chemical found to date, breaking all other chemical records for its potential to impact climate, scientists at the University of Toronto said in a statement.
The man-made chemical has been used in electrical equipment since the mid-20th century, and currently is used for electronic testing and as a heat transfer agent.
It has only now been determined to impact climate, and according to the University of Toronto chemists, there are no known processes for destroying or removing it from the lower atmosphere.
