Move over carbon dioxide : scientists have discovereda new nursery gas , and it ’s 7,000 times more powerful than CO2 in its effects of warming the Earth .
Scientists from the University of Torontohave discoveredthat perfluorotributylamine ( PFTBA ) , which has been in used by the electrical industry since the mid-20th 100 , can have a Brobdingnagian impact on the heating of the major planet . Their inquiry paint a picture that it is 7,100 times more potent at warming the Earth over a 100 - twelvemonth clock time span than CO2 .
In fact , speaking to the Guardian , one of the investigator points out that “ PFTBA has the highest radiative efficiency of any molecule discover in the atmosphere to date . Fortunately for us , the concentration of PFTBA in the atmospheric state is exceedingly gloomy , at just 0.18 parts per trillion ( at least , in the Toronto surface area ) compared to 400 part per million for atomic number 6 dioxide . So , while it ’s potent , it ’s not die to be causing the same problems as the CO2 released from burning fogy fuel . The researchis publish in Geophysical Research Letters .
An industrial chemical , PFTBA has long been used in the fabrication of transistors and capacitors . It remain in the line for about 500 years and , unlike CO2 which is take in by forests and ocean , there are no natural swallow hole for the gas . The overall content ? There ’s not too much to interest about — as long as we do n’t pump too much of the material into our ambiance . [ Geophysical Research LettersviaGuardian ]
