q cnotes: Temperature estimates determined using linear regression between speleothem d18O and annual mean temperature. An "anomalous" period, from AD 1956-1976 was removed from this calibration. In the context of the Holocene, the application of this calibration results in temperature trends contrary to other published records for the last 10,000 years.
use in PAGES2k global temperature analysis: true
