"Fracking is the only way to achieve Obama climate change goals, says senior scientist"
America will only achieve the ambitious climate change goals outlined by President Barack Obama last week by encouraging wide-scale fracking for natural gas over the next few years. That is the advice of one of the nation's senior scientists, Professor William Press, a member of thepresident's Council of Advisors on Science and Technology.
Fracking – known officially as hydraulic fracturing – involves pumping high-pressure water through underground rocks to release natural gas trapped deep underground. It is believed that there are vast reserves of these subterranean gas fields across the US.
Thousands of wells have already been drilled in Texas, leading to a substantial rise in the use of natural gas in the US and a major decline in the burning of coal, a far more serious cause of carbon pollution. However, fracking is also controversial. Environmentalists say it can lead to the contamination of underground water reservoirs and the pollution of the surface with chemicals used to help to release subterranean gas stores. They also point out that burning natural gas releases carbon dioxide.
....Greenpeace says no proper analysis has been done on gas leakage from fracking sites. In particular, there is a fear that methane – which is a far more dangerous greenhouse gas than carbon dioxide – may be escaping from wells and adding to the warming of the atmosphere. Campaigners also claim that there have been more than 1,000 cases of groundwater contamination in the US because of fracking and have urged a moratorium on underground drilling....Yes - it would be great if to have coal companies stop tearing down mountains, It would be great to reduce emissions - but there are many problems with fracking. To say that 'Fracking' is the only way to solve our energy problems is to be blind to many other possibilities.
