[Philip Lelyveld comment; My old schoolmate, Mark Zoback, gives a fact-based 1 1/2 hr lecture on fracking and its role in the transition from coal/oil to renewables.]
Geophysics professor Mark Zoback, a leading international expert on hydraulic fracturing, is working with governments in the U.S., Canada and China to address safe extraction of shale gas. He recently discussed this lightning rod issue with a highly-engaged audience in a new lecture series sponsored by the School of Earth Sciences and Stanford Continuing Studies. http://tinyurl.com/jwvpqkb
