Researchers find new greenhouse gas : worldleaks

worldleaks greenhouse gas

Scientists in Canada have declared the discovery of a greenhouse gas with new potential to warm the Earth, and say the chemical has been lurking in the atmosphere for decades.

The substance – perfluorotributylamine (PFTBA) – ‘is the most radiatively effective 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 on Tuesday.

The man-made chemical has been used in electrical equipment later the mid-20th century, and currently is used for electronic testing and as a heat transfer agent.

It has only now been found to affect climate, and according to the University of Toronto chemists, there are no known processes for destroying or removing it from the lower atmosphere.

‘So it has a very long lifetime, possibly hundreds of years,’ said researcher Cora Young.

‘Calculated over a 100-year time frame, a single molecule of PFTBA has the equivalent climate impact as 7100 molecules of CO2,’ added her colleague Angela Hong.

The findings were printed in the online edition of Geophysical Research Letters.
