Two new types of greenhouse gases are rising

According to an international research team led by scientists at Scripps Institution of Oceanography in the United States and scientist and Dr. Paul Fraser of the Australian Center for Climate and Climate Research, two types of greenhouse gases new is accumulating in the atmosphere.

Nitrogen trifluoride (NF3) and sulfuryl fluoride (SO2F2) are two very powerful greenhouse gases that have just been discovered, showing that they increase rapidly in the global atmosphere.

These gases are used in industrial processes, most of which serve as substitutes for harmful greenhouse gases that degrade the ozone layer.

NF3 is used in the electronics industry, it is an alternative to perfluorocarbons (PFCs) - especially used in the manufacture of liquid crystal flat panel displays. SO2F2 is used to replace methyl bromide, mainly present in structural smoke spray applications. New calculations on the amount of SO2F2 in the atmosphere are published in the March 12, 2009 issue of Geophysical Research magazine by Dr. Fraser.

Dr. Fraser said: 'Information about these gases in the atmosphere, their rate of increase, their life cycle and emissions has only recently been collected. Currently the level of these gases in the atmosphere is still low, but their concentrations are increasing. Besides, they have great potential to make the global climate hotter. '

The first observation of these gases in the atmosphere is that data is collected worldwide, especially in Trinidad Head and La Jolla, California, Cape Grim, and Tasmania will be announced at the GREENHOUSE 2009 conference.

Fraser said: "This study has affected the revision of the Kyoto Protocol later this year. Changes to existing greenhouse gases (such as carbonic, methane, oxide, PFC, hydrofluorocarbon, The sulfur hexafluoride) again leads to the accumulation of new greenhouse gases, many of the developed and developing countries will also participate in the revised Protocol '.
