Four main climatic episodes can be distinguished in this # proxy paleoclimatic record. The first, a cold and moist interval from # A.D. 900 to 1070, was followed by a warm-dry period from A.D. 1080 to # 1250 correlative with the Medieval warm epoch of Europe. Afterward, a # long, cold-moist period followed from A.D. 1270 to 1670, peaking around # A.D. 1340 and 1650. These cold maxima are contemporaneous with two # principal Little Ice Age events registered in the Northern Hemisphere. # Warmer conditions then resumed between A.D. 1720 and 1790. These # episodes are supported by glaciological and palynological data in # Patagonia. Following a cold period in the early 1800s, tree-ring indices # have oscillated around the long-term mean, except for a warmer period # from A.D. 1850 to 1890. Correlations between the Rio Alerce # reconstruction and the regional weather stations indicate that the # tree-ring variations are correlated with a homogeneous summer weather # pattern covering Patagonia east of the Andes from 38° to 50°S. #-------------------- # Funding_Agency #-------------------- # Site_Information # Site_Name: Glaciar Frias # Location: South America>Argentina # Region: PAGES LOTRED SA # Country: Argentian # Northernmost_Latitude: -41.2 # Southernmost_Latitude: -41.2 # Easternmost_Longitude: -71.9 # Westernmost_Longitude: -71.9 # Elevation: 1200 #-------------------- # Data_Collection # Collection_Name: ARGE039 PAGES LOTRED SA # Earliest_Year: 1802 # Most_Recent_Year: 1985 # Time_Unit: AD # Notes: These are processed data.
