Just the first few pages seems to contradict you pretty strongly. The gist as far as I can tell is that complex systems behave in specific ways when changing from one state to another (eg. "an increase in variance in ... fluctuations"), and that the climate currently seems to be undergoing similar fluctuations. It doesn't seem to be particularly vague; I noticed references to things like the inverse power law of species body mass, so they're not just pulling numbers out of their ass. In real world terms? Mass extinctions most likely, just like the last major state shift.
