  Kossin et al. (2020) successfully test (over the last four decades) the
prediction of climate-change models that conditional tropical cyclone intensity
(the frequency of major [category 3-5] cyclones divided by the frequency of all
cyclones) should increase. Yet, the highest relative proportional increase in
incidence occurred in category 3 cyclones. The highest relative proportional
decrease occurred in category 5 cyclones. This inference is not due to
different treatment of measurement error. It is plausibly due to lower power
for relatively rarer category 5 cyclones.
