more, a possible link between solar vari-
ability and peat bog records has been sug-
gested. A transect approach can be used to
test the following working hypothesis:
“Periodic latitudinal shifts in average
depression tracks over the North Atlantic
region have caused periodic, and some-
times abrupt, changes in mire surface
wetness, vegetation assemblages and
rate of peat decomposition over at least
the last 5,000 years ”
Furthermore, it may be suggested that a
component of such periodicity and abrupt
changes could be a result of changes in so-
lar output. This could be tested in turn by
attempting to correlate regional proxy cli-
mate records with long-term solar proxies
namely cosmogenic isotope concentrations
(Blackford and Chambers, 1995).
