article_snippet.sent: The gases - desflurane, isoflurane and sevoflurane - are potent greenhouse gases that have 2,500 times the impact on global warming compared to carbon dioxide.
article_snippet.sent: Atmospheric scientists who have been monitoring the gases say that while the concentrations in the atmosphere are low, Atmospheric scientists who have been monitoring the gases are having an increasing effect on the climate.
article_snippet.sent: Dr Martin Vollmer, who led New study at the Swiss Federal Laboratories for Material Science and Technology in Dubendorf, Switzerland, said the gases were capable of storing far more energy from the sun than carbon dioxide.
article_snippet.sent: He said: 'On a kilogram-per-kilogram basis, it's so much more poten . '
article_snippet.sent: By comparison, carbon dioxide gas currently makes up 400 parts per million in the atmosphere.
article_snippet.sent: However, one kilogram (2.2lbs) of desflurane produces the same greenhouse effect as 2,500 kg (5,512lbs) of carbon dioxide.
highlights_snippet.sent: The gases - desflurane, isoflurane and sevoflurane - have a greenhouse effect that is 2,500 times more potent than carbon dioxide, say scientists .
