What does a frequency vs GRB-energy (integrated gamma energy above the atmosphere) plot look like? There should be enough data collected by now. Extrapolating this, and making some general assumptions about the source distribution, how many 'devastating to life on Earth' GRBs might there have been in the last 1 billion years?

Possibly........however, there would be trace residules left..and there are not. For a better idea (perhaps) read the chapter on reoccurring extinctions from my book "Losing Faith" for a sustainable and provable argument.

What 'trace residules' would you expect there to be?

That's what I'm wondering as well. surely he doesn't mean left over gamma rays?
