N2 - One of the key questions facing climate scientists, policy makers and
the public today, is how important is natural variability in explaining
global warming? Sedimentary archives from marginal marine environments,
such as fjordic (or sea-loch) environments, typically have higher
sediment accumulation rates than deeper ocean sites and thus provide
suitably expanded archives of the Holocene against which the 20th
Century changes can be compared. Moreover, with suitable temporal
resolution, the impact of Holocene rapid climate changes episodes, such
as the 8.2 kyr event can be constrained. Since fjords bridge the
land-ocean interface, palaeo-environmental records from fjordic
environments provide a unique opportunity to study the link between
marine and terrestrial climate. Here we present millennial to centennial
scale, independent records of marine and terrestrial change in two
fjordic cores: from Ìsafjardardjúp, northwest Iceland
(core MD99-2266; location: 66° 13' 77'' N, 23° 15' 93'' W; 106m
water depth) and from Loch Sunart, northwest Scotland (core MD-04 2832;
location: 56° 40.19'N, 05° 52.21 W; 50 m water depth). The cores
are extremely high resolution with 1cm of sediment representing
