ABSTRACT
Affirmation that, in and around Europe, a salubrious warming trend was well sustained from sometime in the ‘Dark Ages’ to the thirteenth century has long been a sine qua non for scholars concerned with climate change. What basically occurred was a moderate rate of evolutionary progression over an extended time span. Secular changes in mean temperature were markedly slower than what was characteristic of the onset or conclusion of the Older or Younger Dryas events, or is of contemporary global warming.
