... how much traction that the original authors obtained in the geologic community with their hypothesis.  For a fact, you are the only person I have ever met who seriously claimed that humanity was headed into a Permian-level extinction event because fossil fuel use.

Re:  methane burps, my understanding of the current science is informed by Ruppel's 2011 paper (involving numerical modeling, no less!), who concluded that it was highly unlikely in the modern world, even with projected anthropogenic inputs to global climate.  The reference is:  Ruppel, C. D. (2011), "Methane Hydrates and Contemporary Climate Change", in _Nature Education Knowledge_ 3(10):29.    Are you familiar with this paper, or similar efforts of more recent vintage?

(Ruppel, incidentally, is USGS and did this study at Woods Hole.  A credible source, I think - i.e., not _Mother Jones_ or Fox News.)  ;-)

Thank you for an interesting exchange of views.
