LiveScience: A greenhouse gas that is thought to have a potent impact on global warming was detected in trace amounts in the atmosphere for the first time, according to a new study.
Researchers at the University of Toronto discovered very small amounts of an industrial chemical, known as perfluorotributylamine (PFTBA), in the atmosphere. While only traces of PFTBA were measured, the chemical has a much higher potential to affect climate change on a molecule-by-molecule basis than carbon dioxide (CO2), the...
