Researchers in Toronto have discovered a new greenhouse gas that is more powerful than carbon dioxide at warming the Earth. Perfluorotributylamine (PFTBA) is the name of the newly discovered gas, which has been used by the electrical industry since the mid-20th century.
The chemical (PFTBA) does not occur naturally and it breaks all records for potential impacts on the climate...
Geophysical Research Letters journal published the study and found PFTBA was 7,100 times more powerful at warming the earth over a 100-year time span than CO2.
PFTBA concentrations in the atmosphere are low-0.18 parts per trillion in the Toronto area – compared to 400 parts per million for carbon dioxide. So PFTBA does not in any way displace the burning of fossil fuels such as oil and coal as the main drivers of climate change.
Dr. Drew Shindell, a climatologist at Nasa’s Goddard Institute for Space Studies, said; “This is a warning to us that this gas could have a very very large impact on climate change – if there were a lot of it. Since there is not a lot of it now, we don’t have to worry about it at present...
PFTBA remains in the atmosphere for about 500 years, estimate the Toronto researchers, but PFTBA is long-lived and unlike carbon dioxide, that is taken up by fossil fuels and oceans, there are no known natural “sinks” on earth to absorb it.
... But i cant see how in the world it would get into the atmosphere in any amount to make the slightest difference.
