text: I'm not sure I owe you or anyone else a resume but I do have a BS and MS in the Sciences, plus 50 yrs working the sciences.  So as to my "bold statement" about the words used in the article, any statement that is completely inclusive, ie. some act of nature being "totally driven by man" is on face value an error.  Nature is too chaotic, almost nothing in nature is totally driven by one force.  If an exotic like a mammoth walked the north slope today, would we consider this exotic to be totally caused by man, just because it is at this date an exotic? Exotic species is a relative term. Milankovitch Cycle theory describes the collective effects of changes in the Earth's movements over geologic time periods and these movements effects on Earth's paleoclimate, perhaps this bit of science might have some validity too.
