Complicating the feud between Mike’s defenders and his detractors is that he gave the latter group so much rope to hang him with. In the last years of his life, he publicly aired the sort of views about extra-worldly affairs (aliens, the symbolism of the appearance of an eagle at a particular time) which can never be substantiated. He’s not alone in believing that a spirit or god communicated with him or others in these ways. But they’re the sort of beliefs that anyone staking his reputation on concrete evidence would be advised to keep to himself.
One fact cited in the article which I’d like to clarify is the date of Peak Oil. Extrapolating from a graph in Crossing the Rubicon, the article implies that global peak took place in the 1960’s. The graph, however, was referring to the peak of discovery. There’s a significant gap between that and the peak of production which may have taken place c. 2008 or is taking place around now.
