Supplemental Information | STUDY NOTES: 4,500 year scaled summer paleotemperature reconstruction for the Great Basin, USA, based on three high elevation tree-ring collections of Great Basin bristlecone pine (Pinus longaeva). The GB3rwi tree-ring chronology is based on 3 P. longaeva collections: (1) Sheep Mountain, White Mountains, CA (SHP, 37.52 N. lat., 118.20 W. long.); (2) Mt. Washington, Snake Range, NV (MWA, 38.91 N. lat., 114.31 W. long.); and (3) Pearl Peak, Ruby Mountains, NV (PRL, 40.23 N. lat., 115.54 W. long.). Temperature anomalies were computed based on the AD 1000-1990 July-September mean of 20.32C 'near surface' from the ERIK2 model. A millennial-scale trend adjustment for the preindustrial period of 2575 BC to AD 1328 was then applied by adding a negative trend of 1.102C based on empirical data from treeline elevation change. There were no adjustments made to the period after AD 1328. ABSTRACT SUPPLIED BY ORIGINATOR: The instrumental temperature record is of insufficient length to fully express the natural variability of past temperature. High elevation tree-ring widths from Great Basin bristlecone pine (Pinus longaeva) are a particularly useful proxy to infer temperatures prior to the instrumental record in that the tree-rings are annually dated and extend for millennia. From ring-width measurements integrated with past treeline elevation data we infer decadal- to millennial-scale temperature variability over the past 4,500 years for the Great Basin, USA. We find that twentieth century treeline advances are greater than in at least 4,000 years. There is also evidence for substantial volcanic forcing of climate in the preindustrial record and considerable covariation between high elevation tree-ring widths and temperature estimates from an atmosphere-ocean general circulation model over much of the last millennium. A long-term temperature decline of ~-1.1 °C since the mid-Holocene underlies substantial volcanic forcing of climate in the preindustrial record. |
