Fracking for shale gas `leading to dramatic increase in methane´
(World News UK)

The boom in fracking for shale gas has `dramatically increased` global methane emissions in the past decade, a study has warned. While the rapid rise in levels of methane, a significant greenhouse gas, in recent years has been attributed to biological sources such as cows, tropical wetlands and rice fields, new research points to the role of fracking. The research from Cornell University looks at the `chemical fingerprint` of methane in the atmosphere and concludes that around a third in the past decade has come from exploiting shale gas. Methane levels rose steadily in the last decades of the...
