The new data show generally higher temperature estimates than previous reconstructions based on Torneträsk tree-ring data. The late-twentieth century, however, is not exceptionally warm in the new record: On decadal-to-centennial timescales, periods around ad 750, 1000, 1400, and 1750 were equally warm, or warmer. The 200-year long warm period centered on ad 1000 was significantly warmer than the late-twentieth century (p < 0.05) and is supported by other local and regional paleoclimate data. The new tree-ring evidence from Torneträsk suggests that this “Medieval Warm Period” in northern Fennoscandia was much warmer than previously recognized.As the infamous Phil Jones recently admitted in an interview
"Of course, if the MWP was shown to be global in extent and as warm or warmer than today, then obviously the late 20th Century warmth would not be unprecedented. On the other hand, if the MWP was global, but was less warm than today, then the current warmth would be unprecedented"OK Phil, here ya go: Medieval Warming Period was Global
The Torneträsk pines have a sordid history thanks to Michael Mann's highly flawed "statistical" techniques and mentions in climategate emails. For more on this see:
This is interesting. I was just playing with some historical stuff and comparing it to the Jose Cycle and in the end ... I am starting to think the Holocene Interglacial is over.ReplyDelete
We both independently came to the conclusion the end of the Holocene and start of the next glaciation was around 500 AD. I guess the next Heinrich Event will push us off the cliff when the time comes, I'm betting within a millenium.
interesting chart - let me know if you'd like to write a paragraph or two on your analysis and I'll headline it as a new post. You might be interested in 2 papers predicting the current interglacial will be extended:ReplyDelete
