The producers of Bloggingheads.TV invited me to join Abrahm Lustgarten of ProPublica in a discussion of the drilling boom aimed at the vast deposits of natural gas identified in deep shale layers and other deposits around North America and, increasingly, the world. Lustgarten is a lead reporter and writer in ProPublica’s ongoing Buried Secrets project on environmental problems related to the gas boom.

We recorded the chat just one day after drillers lost control of a Pennsylvania gas well. Environmental officials did not detect significant contamination in nearby waterways, but the blowout prompted the drilling company, Chesapeake Energy, to suspend all hydraulic fracturing, or fracking, activities around the state while the incident is evaluated.

Here’s the opening video, with links to subsequent sections:

Here’s more from Dot Earth on issues and opportunities related to extracting natural gas.

Postscript: I spent an hour on Thursday exploring the state of the planet on “Dr. Kiki’s Science Hour” with Kirsten Sanford, a neurophysiologist and science writer and interviewer:

I discuss humanity’s “capacity to surprise ourselves in positive ways,” which so far has gotten us out of a variety of jams; the ideological blog wars; the intended meaning of my Pace University title, “senior fellow for environmental understanding”; how a scallop’s underwater dance inspired me to dive into science; and much more.
