“A regional approach to the medieval warm period and the little ice age“. Anthony Watts jabbers about the Medieval Warm Period and Little Ice Age again, using a paper by Dr. Fredrik Charpentier Ljungqvist by a history grad student at Stockholm University titled “A regional approach to the Medieval Warm Period and the Little Ice Age“. Has it been submitted? Reviewed? Published? Who knows.
Funny how denialists are always pointing out regional evidence to try to challenge global climate trends. Well, it’s not really funny, it’s kind of boring and a predictable intellectual bankruptcy. Strange that there’s no whining about Urban Heat Islands and sneaky “corrections” to proxies or mutterings about the failings of computer models, etc. when the denialists think the result suits them.
The paper, using only use northern hemisphere locations, claims that the Medieval Warm Period and Little Ice Age were global although they seem to have somehow happened a different times in different regions. Hmmm. But this is the first sentence of Dr. Ljungqvist’s concluding remarks:
The presently available palaeotemperature proxy data records do not support the assumption that late 20th century temperatures exceeded those of the MWP in most regions, although it is clear that the temperatures of the last few decades exceed those of any multi-decadal period in the last 700–800 years. (Emphasis mine)
Anthony seems to find the Greenland reconstruction fascinating, as it plays in to his meme that “it’s been warmer in the past, so why worry about this warmth (which isn’t happening).”
