claim: Tree-ring proxy reconstructions are reliable before 1960, tracking closely with the instrumental record and other independent proxies.
evidences.evidence_id: Divergence problem:8
evidences.article: Divergence problem
evidences.evidence: The deviation of some tree ring proxy measurements from the instrumental record since the 1950s raises the question of the reliability of tree ring proxies in the period before the instrumental temperature record.

evidences.article: Temperature record of the past 1000 years
evidences.evidence: The temperature record of the past 1,000 years or longer is reconstructed using data from climate proxy records in conjunction with the modern instrumental temperature record which only covers the last 150 years at a global scale.

evidences.evidence_id: Temperature record of the past 1000 years:19
evidences.article: Temperature record of the past 1000 years
evidences.evidence: As there are few instrumental records before 1850, temperatures before then must be reconstructed based on proxy methods.
