A Mathematical Model of Altruism
https://www.theatlantic.com/science/arch...ks/538842/

EXCERPT: [...] Of course, since any mathematical model excludes some features and oversimplifies others, we must be careful not to draw overly broad conclusions. History is littered with utopian ideas that looked great on paper but collapsed in practice. Still, mathematical modeling can be quite effective in separating promising ideas from those that are conceptually flawed. Recently, I led a team of investigators to mathematically model how the structure of a society can encourage or suppress the evolution of cooperative behavior....

soo.... after having a bit of a look, it appears what needs to be done is the cyclones need to be analysed
by their wind speed increase peaking time scale. it appears that irma has a second peak.
is there a developing trend for secondary peaking of wind speed now there is a warmer climate ?

Over the years, re-intensifications after post-peak-intensity weakening phases have resulted in secondary peak intensity being recorded for even lesser or smaller hurricanes. The secondary peak is usually if not always lower, but can still be significant if the hurricane is of powerful class to begin with.  

Data-wise circa the last four decades, when the peak intensities of hurricanes occur they seem to be experiencing a general trend-shift of moving locationally away from the direction of the equator and toward the direction of the poles. (Affecting areas formerly less assaulted by hurricane activity.)
