This peer reviewed report does not support the less accurate, less scientific, more popular climate change narratives bandied about today by people with low degrees of understanding about climate change issues.

ABSTRACT: The 1000 yr. climatic and environmental history of the Earth contained in various proxy records is reviewed. As indicators, the proxies duly represent local climate. Because each is of a different nature, the results from the proxy indicators cannot be combined into a hemispheric or global quantitative composite. However, considered as an ensemble of individual expert opinions, the assemblage of local representations of climate establishes both the Little Ice Age and Medieval Warm Period as climatic anomalies with worldwide imprints, extending earlier results by Bryson etal. (1963), Lamb (1965), and numerous intervening research efforts. Furthermore, the individual proxies can be used to address the question of whether the 20th century is the warmest of the 2ndmillennium locally. Across the world, many records reveal that the 20th century is probably not the warmest nor a uniquely extreme climatic period of the last millennium. ...
Many interesting questions on the geographical nature and physical factors of surface temperature or precipitation changes over the last 1000 yrs. cannot be quantitatively and conclusively answered by current knowledge. The adopted period of 1000 yrs. is strictly a convenience that merits little scientific weight. Climate proxy research provides an aggregate, broad
perspective on questions regarding the reality of Little Ice Age, Medieval Warm Period and the 20th century surface thermometer global warming. The picture emerges from many localities that both the Little Ice Age and Medieval Warm epoch are widespread and near-synchronous phenomena, as conceived by Brysonet al. (1963), Lamb (1965) and numerous researchers since. Overall, the 20th century does not contain the warmest anomaly of the past millennium in most of the proxy records, which have been sampled world-wide. Past researchers implied that unusual 20th century warming means a global human impact. However, the proxies show that the 20th century is not unusually warm or extreme.
