After slogging through this article, one gets to the bottom:
Naturally, on top of this increase of the baseline terrestrial temperature, there are imposed much larger temperature oscillations caused by standard solar activity cycles of 11 and 350–400 years and terrestrial causes. The terrestrial temperature is expected to grow during maxima of 11 year solar cycles and to decrease during their minima. Furthermore, the substantial temperature decreases are expected during the two grand minima to occur in 2020–2055 and 2370–2415, whose magnitudes cannot be yet predicted and need further investigation. These oscillations of the estimated terrestrial temperature do not include any human-induced factors, which were outside the scope of the current paper.
So, if this is a correct prediction, then the terrestrial temperature should be decreasing during the predicted 2020-2055 mimina? Hmmm.....food for thought for those on the fence when it comes to "Global Warming".
