Controversy abounds over the temperature history of the earth, particularly that of the past one to two millennia. The original debate was sparked by the papers of Mann et al. (1998, 1999), which challenged the long-accepted view that there was nothing unusual about earth’s climatic history subsequent to the inception of the Industrial Revolution; and it prompted the Intergovernmental Panel on Climate Change (IPCC) to disavow their original representation of the temperature history of the Holocene (Houghton et al., 1990), where several periods of time prior to the inception of the Industrial Revolution were depicted as having experienced temperatures that were higher than those of the latter part of the 20th century.
