I applaud your effort to bring actual data to the discussion, but I'm not certain those links support your claim of temperatures "equal to or higher than todays". Closest I could find in the first paper was:
The level of warmth during the peak of the MWP in the second half of the 10th century, equalling or slightly exceeding the mid-20th century warming, is in agreement with the results from other more recent large-scale multi-proxy temperature reconstructions
(emphasis mine) ... but we know global temperatures have risen significantly in the last 60 years. Do you have evidence that this is not the case in Europe?
The second link was paywalled, but the abstract says northern Sweden experienced "similar levels of summer warmth in the medieval period (MWP, c. CE 900–1100) and the latter half of the 20th century". Hard to pin down the comparison dates, but again, not "equal or higher than today".
The third link says that some reconstructions of northern Sweden and Finland specifically have indeed been up to 0.6C warmer 2000 years ago, when compared to the 1951-1980 mean (rather than today's warmer temperatures), but also says that proxy reconstructions can vary wildly, by 1.5-3C, depending on which Scandinavian record is used, and finishes with:
We conclude that the temperature history of the last millenium is much less understood than often suggested, and that the regional and particularly the hemispheric scale pre-1400 temperature variance is largely unknown.
So basically, it was certainly fairly warm in Europe during certain past periods, but the evidence is not reliable enough to say exactly how warm, and no paper supports the claim that it's "equal or higher than todays" temperatures. In any case, Europe in general (and Sweden/Finland in particular) are only one part of the global picture; temperatures were relatively low elsewhere in the world even during the MWP.
