The above article summarizes and critiques a research paper
by Marcott, Shakum, Clark, and Mix. According to Hoffman that
paper was widely commented upon in the popular media, often
giving the impression that global temperature rises over the 
last half century or so are unprecedented.

Hoffman concludes that decade and century scale temperature
changes, for times before instrument-based written records, are
unknown. Hoffman also concludes that yearly average temperatures
over the last few decades are not higher than some years during
a warm period at 10,000 to 5,000 years ago.
