Figure 6.4 Series of
Holocene climatic records
from the Northern
Hemisphere with those at
the top of the page from
high latitudes and those at
the bottom of the page from
lower latitudes. Climatic and
environmental significance
of each record is noted in the
figure. Light gray columns
represent the timing of rapid
climate change (RCC) events
during the Holocene as
identified by the authors,
whereas darker gray shading
on individual time series
represents sections within
individual time series that
display anomalies. (From
Mayewski et al.(
2004
),
where details of the sources
of the individual curves can
be found)
