Marine climate proxies (alkenone sea surface temperatures [SSTs] and CaCO<jats:sub>3</jats:sub>%) behaved remarkably like the Greenland Ice Sheet Project (GISP)‐2 oxygen isotope record during the Bølling‐Allerod, Younger Dryas (YD), and early part of the Holocene. During the YD, alkenone SSTs decreased by >3°C below mean Bølling‐Allerod and Holocene SSTs. The early Holocene (ca. 11.6 to 8.2 ka) was a time of generally warm conditions and moderate CaCO<jats:sub>3</jats:sub> content (generally >4%). The middle part of the Holocene (ca. 8.2 to 3.2 ka) was marked by alkenone SSTs that were consistently 1–2°C cooler than either the earlier or later parts of the Holocene, by greatly reduced numbers of the gyre‐diatom <jats:italic>Pseudoeunotia doliolus</jats:italic> (<10%), and by a permanent drop in CaCO<jats:sub>3</jats:sub>% to <3%. Starting at ca. 5.2 ka, coastal redwood and alder began a steady rise, arguing for increasing effective moisture and the development of the north coast temperate rain forest. At ca. 3.2 ka, a permanent ca. 1°C increase in alkenone SST and a threefold increase in <jats:italic>P. doliolus</jats:italic> signaled a warming of fall and winter SSTs. Intensified (higher amplitude and more frequent) cycles of pine pollen alternating with increased alder and redwood pollen are evidence that rapid changes in effective moisture and seasonal temperature (enhanced El Niño–Southern Oscillation [ENSO] cycles) have characterized the Site 1019 record since about 3.5 ka.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1382544420299348993","@type":"Researcher","foaf:name":[{"@value":"John A.
