In March 2011, Cornell professors Robert Howarth, Renee Santoro and Tony Ingraffea published a peer-reviewed study in the journal Climatic Change titled,  “Methane and the greenhouse-gas footprint of natural gas from shale formations” (see this MDN story). The study makes the claim that shale gas extraction is actually worse for the environment than burning coal because of greenhouse gases. Howarth et al’s conclusions were roundly refuted by both the U.S. Dept. of Energy (see this MDN story) and by a Carnegie Mellon University study (see this MDN story).

You can now add another group of Cornell professors to the list of those refuting the poor quality of the Howarth study. Cornell professors Lawrence M. Cathles, Larry Brown, and Andrew Hunter, along with Milton Taam (Electric Software, Inc.) have just published an article in the very same journal responding to the Howarth article. This new peer-reviewed article appears in the January 2012 issue of Climatic Change (a copy of the full article is embedded below).
