In July, I participated in the Union of Concerned Scientists’ forum on Science, Democracy, and Community Decisions on Fracking in Los Angeles that I've blogged about previously. The full webcast of the event is available at this new link, and a summary video here.
UCS has posted two short companion videos: The Curious Case of Fracking and Reflections from Experts and Citizens. includes some brief commentary from me on the need for 3-part regulation of unconventional oil and gas development - a Federal floor upon which states can build regulations that reflect their geology and geography, and a measure of local control to protect the health and safety of citizens and the integrity of communities. All of that regulation needs to be grounded in science.
My section of the clip begins at about the 3:50 mark.
