Abstract J. Hansen et al. (2015) provided six geological criteria “that support a rapid late-Eemian sea-level rise and superstorms“. However, we must state that none of these “geologic data” is seriously capable (i) of challenging an eolian origin of the so-called chevron and runup deposits exposed on several Bahamian islands, and (ii) of reliably excluding other processes than superstorm-related, long-period waves for transport of the large boulders on Eleuthera. The origin of the latter could as well be due to a low-frequency, high-magnitude, local tsunami related to submarine mass failure.
