  abstract = {{A} long terrestrial record, {C}olonia {CO}-3, from the {A}tlantic rainforest region in {B}razil (23 degrees 52'{S}, 46 degrees 42'20 "{W}, 900 in a.s.l.) registrates variations in the forest expansion during the last 100,000 yr. {T}he 780-cm depth core was analyzed at 2-cm intervals and arboreal pollen frequencies were compared to nearby speleothem stable isotope records and neighboring marine records from the tropical {A}tlantic. {T}o evaluate regional versus global climate forcing, our record was compared with {G}reenland and {A}ntarctic ice-core records. {T}hese comparisons suggest that changes in temperature seen in polar latitudes relate to moisture changes: e.g., to changes in the length of the dry season, in tropical and subtropical latitudes during glacial as well as interglacial times. {T}hese climatic changes result from changes in the frequency of polar air incursions to these latitudes inducing a permanent cloud cover and precipitation. {T}his is an important result that should help define paleoclimatic features in the {S}outhern {H}emisphere for the last glaciation.
