- "How to Talk to a Climate Sceptic. The Medieval Warm Period was just as warm as today." February 23, 2006 - "Objection: It was just as warm in the Medieval Warm Period as today, in fact Greenland was green and they were growing grapes in England. This one often comes with additional anecdotal evidence, but it is not often useful to get into those details, just refer to the wealth of proxy studies that refute this idea.
- Answer: There is actually no good evidence that the MWP was indeed a globally warm period comparable to today. Regionally, there may have been places that did exhibit notable warmth but all of the various global proxy reconstructions agree that it is warmer now and the temperature is rising faster than at any time in the last one or even two thousand years. Anecdotal evidence like that above can never tell you a global story."
- NOAA materials on the issue. [1]
- "The idea of a global or hemispheric 'Medieval Warm Period' that was warmer than today however, has turned out to be incorrect."[2]
