Canadian researchers discover new greenhouse gas

Scientists in Canada
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.
In a statement, scientists
at the University of Toronto said, “The substance - perfluorotributylamine
(PFTBA) - is the most radiatively efficient chemical found to date, breaking
all other chemical records for its potential to impact climate.”
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.
