A quick scan suggests that since 2010, no summer has finished below 55th out of 135 on the warmest summers list. If you take being in the bottom 50% as a "cool summer", they are literally history for now. The last time we had a cool summer/bottom 50% of the totals in MDT history was in 2009 unless I missed one in scanning. Every one of the next 14 summers has been above the 50% line. The most telling stat of all, out of the top ten warmest summers at MDT, 6 have occurred since 2010. In a sample size that equates to just barely over 10% of all summers in recorded MDT history, 60% have been top 10.
