Fréchette bianca.frechette@internet.uqam.ca A. de Vernal GEOTOP, Université du Québec à Montréal, C.P. 8888, Succursale centre-ville, Montréal, Québec, H3C 3P8, Canada Lake pollen records from southwest Greenland and eastern Baffin Island show strong regionalism in climate trends of the last 7000 years. Air temperature reconstructions from pollen indicate larger amplitude cooling in southwest Greenland (>3.0°C) than in eastern Baffin Island (<1.0°C). Such west-east gradient in climate change is consistent with paleoceanographical data that indicate decreasing temperature and/or strength of the North Atlantic Current to the east during the Holocene while the eastern Canadian margins under the Labrador Current influence display slight warming. Complementary to air and sea temperature records, the lake pollen data led to reconstruct increased cloudiness in southern Greenland, which points to increasing cyclonic activity since 7000 years west of Greenland. Together, the terrestrial and marine records of the northwest North Atlantic therefore suggest a shift from a dominant NAO+ during the early-mid Holocene to dominant NAO- in the late Holocene.
