Global temperatures during the Medieval Warm Period from the years 1000 to 1200 closely matched the warming trend of the 20th century, says a study of tree rings appearing in today's issue of the journal Science. This was accepted as fact and is backed by large amounts of data, but the Global Warmers did some Scientific Genocide and used statistical majic and eliminated the Little Ice Age and Medieval Warm Period from the record to match thier lies.
The scientists who promoted the Mann hockey stick climate reconstruction should be arrested for fraud and quackery, now that this new study is out.
