A new peer-reviewed paper looks at the historical temperatures in northern Scandinavia. It finds:
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.
This is just one region of the Arctic, of course, but it provides yet more evidence that we know very little about natural climate variability.
Of course, the authors do not actively cast doubt on the theory of “man-made global warming” so, by default, this is part of the literature supporting the “consensus,” according to the alarmists’ formulation.
