Gentlemanly Conduct on the Internet
HEINRICH VS BARBIERO

Can I kindly remind members of the Cambridge-
Conference network to avoid offensive or inflammatory
language. Since neither Dr Heinrich nor Dr Barbiero
are members of this list, a reminder of the
intellectual standards of this network is essential
should they wish to contribute any further messages.

Gentlemanly conduct also includes acknowledging well-
considered criticism. Evidently Dr. Barbiero does not consider
the two criticisms posted by me last week to be such, or else
he somehow did not receive them. In any event, do not let
the allegation that Heinrich missed Barbiero's point persuade
anyone that Bartbiero's model somehow retains credibility,
much less validity. I say this because the model in question
requires that a new equatorial bulge form as the present one
relaxes, all on the time-scale of the impact event. This is
preposterous on its face because the mantle is too viscous/stiff
to deform to such a degree on such a short time-scale--besides
the fact that it takes ca. 85 minutes for any impact to propagate
its effects over the entire body of Earth. The daily luni-solar tides
of ca. 18 inch amplitude do not justify the requirement that a new
ca. 11 km bulge form as the present one relaxes because the
mantle is still rebounding in Laurentia and Fennoscandia from the
melting of the last ice cap ca. 10,000 years ago. The 1/e time
for the relaxation of a mantle deformation is ca. 3,400 years,
which is borne out by the observed, ongoing post-glacial rebound
in the aforementioned regions. What is wrong with this criticism?
I am also still impressed with the immplications of the scaled-down
Barbiero model wherein a 1.0 mm grain of sand impact a 25 meter
diameter granite sphere. This, by itself, suggests the utter
impracticality of Dr. Barbiero's model. One other aspect of Heinrich's
criticism deserves reinforcement: there is NO VALID EVIDENCE
that the Earth experienced a pole shift in the early Holocene. All
of Hapgood's so-called evidence can be, and has been, explained
in terms that require no shift; plus, as Burns noted, the work of
Laskar published in 1993 shows that Earth's obliquity is stabilized
not only by the equatorial bulge, but also by the presence of the
Moon, in distinct contrast to the case with Mars which has no
large satellite and shows distinct physical evidence for ca. 90 degree
polar wander on geological time scales, as opposed to time scales
on the order of less than a day. What is wrong with this criticism?

Emilio Spedicato passed on to me a reply from Flavio Barbiero to
Paul Heinrich's criticism of Barbiero "pole shift" paper. I append Mr.
Barbiero's comments below. I have forwarded a copy to Mr. Heinrich.
