New Scientist: Fracking risk is exaggerated.
$$*%(%^$^. As per usual, this geologist is looking at a small subset of inputs, and generalizing them outwards to absolve fracking of most risk. There are multifarious ways fracking can harm the environment. The cement around the bore fails all too often (vibration+cement is a terrible idea in the first place). The layers of rock above the frack are not definitively known, so seepage and migration can and will often occur. We see this in Los Alamos, where the deep bores used for storing toxics are migrating to the surface way, way ahead of schedule (like, 550 years ahead of expectation). Perhaps the “impenetrable layer of rock” theory should be removed from its pedestal, and re-tested ... ? That would be the real scientific thing to do. Instead, some dig in their heels and refuse to be scientists.
