2019 will likely be one of the hottest years on records, hotter than 2018, and 2015-2018 are the 4 hottest years on record. Also, this analysis did not include any years after 2000.
The analysis was done on 51 year time frames, so solar minimums would be averaged with solar maximums.
Also, the solar minimum should occur next year and it won't produce any more cooling than we experienced this year.
