New Scientist;9/30/2006, Vol. 191 Issue 2571, p6
This article reports that according to the Norwegian Institute for Air Research, concentrations of powerful greenhouse gas, called HFC134a, above Mount Zeppelin doubled during 2001-2004. HFC134a has a warming effect on the climate more than a thousand times that of carbon dioxide. Since the ban on the chemically related chlorofluorocarbons, HFC134a is being used in air conditioning systems.

    CFC-113a (CF3CCl3), CFC-112 (CFCl2CFCl2) and HCFC-133a (CF3CH2Cl) are three newly detected molecules in the atmosphere that are almost certainly emitted as a result of human activity. It is important to characterise the possible contribution of these gases to radiative forcing of climate change...
