    The actual plot from the first reference in this Paper Coleslaw of an OP.

    From the reference :

    Comparison with previous reconstructions
    1, 35, 7, 9, 21, 71] of reconstructed NH mean temperature (Fig 7). To facilitate the comparison, all reconstructions were 30-year low-pass filtered, and scaled to the smoothed instrumental series by the variance and mean over the common period 1865–1973 AD. It was found that our reconstruction was very similar to those from other studies in terms of the multi-decadal variability. The MDVM reconstruction captured much larger cooling during the LIA relative to the reference period, but also comparable warming signals in the MWP. In particular, the low-frequency variability indicated by MDVM reconstruction was more evident than the two reconstructions [3, 4] based solely on tree-ring data. It appeared that for the NH, the LIA maximum cooling occurred mainly centering in 17th century, and the recent warming in 20th century seemed to be unprecedented over the past millennium. Fig 8 presents the correlation coefficient matrix for all above NH temperature reconstructions (30-year low-pass filtered) over the common period 1000–1973. The correlation coefficients between the MDVM series and other reconstructions were relatively high as a whole, without any values lower than 0.6. These results further illustrated that MDVM reconstruction was in good agreement with others particularly in terms of the multi-decadal variability.

    And I repeat:

    the recent warming in 20th century seemed to be unprecedented over the past millennium.

    No point looking any further .
